Description

Technical Field

[0001] This application relates to the field of machine tool technology, specifically to a machine tool structure and machining center that integrates a worktable and a tool magazine. Background Technology

[0002] In the context of the rapid development of modern manufacturing, machine tools, as core processing equipment, directly impact production efficiency and manufacturing costs through their performance, structural rationality, and space utilization. As a widely used type of machine tool, the arrangement of the tool magazine in machining centers is one of the key factors influencing the optimization of the overall machine structure. Reducing the overall size of the machine tool, minimizing its footprint, integrating the machine tool structure, and minimizing redundant structures have become the main optimization directions and design concepts for machine tool tool magazine layout.

[0003] Currently, there are two main types of tool magazine layouts in machine tool machining centers, but both have certain limitations:

[0004] One approach is to place the tool magazine on the side of the machine tool. While this arrangement can avoid direct interference between the tool magazine and the machining area of ​​the worktable to some extent, it often requires reserving a large amount of additional space on the side of the main machine tool structure to ensure the installation space for the tool magazine and the feasibility of tool changing operations. This directly increases the overall width of the machine tool. In workshop production layout, the increased footprint of the machine tool reduces the number of devices that can be accommodated per unit area. This not only increases the rental or construction costs of production sites but also hinders the spatial planning of material transportation and equipment maintenance in the production process, contradicting the current trend in manufacturing towards compact and efficient production layouts.

[0005] Another approach is to mount the tool magazine on top of the machine tool base. This arrangement controls the machine tool's lateral dimensions to some extent, but to achieve tool changing, a separate drive mechanism is often required to move the tool magazine in a specific direction to coordinate with the spindle for tool changing. This additional drive structure not only increases the number of machine tool parts, making the overall structure more complex, but also increases manufacturing costs and assembly difficulty. Furthermore, an additional drive structure means an additional control and power transmission system, which increases the risk of malfunctions during machine tool operation, reduces equipment reliability, and contradicts the development principles of integrated and simplified machine tool structures, hindering the achievement of lightweight and high-efficiency operation.

[0006] Furthermore, both of the above-mentioned arrangement methods have room for improvement in tool changing efficiency. With a side-mounted tool magazine, the spindle needs to move a relatively long distance to reach the tool changing position during tool changing; with a tool magazine located on the top of the base and equipped with an independent drive, the coordination between its movement and the spindle requires more complex control logic, which can easily affect the tool changing speed due to synchronization issues.

[0007] Therefore, it is necessary to develop a tool magazine layout method that can effectively reduce the machine tool footprint, improve the degree of structural integration, simplify the drive system, and ensure tool changing efficiency. Utility Model Content

[0008] The purpose of this application is to provide a machine tool structure that integrates the worktable and the tool magazine, so as to solve the problems of large footprint or low integration level caused by the tool magazine layout in the prior art.

[0009] The technical solution adopted in this application is as follows:

[0010] A machine tool structure integrating a worktable and a tool magazine includes a base, columns fixed on both sides of the base, a crossbeam connected to the top of the columns on both sides, and a spindle mounted on the crossbeam. The machine tool structure includes a worktable and a tool magazine. The worktable is divided into a machining area and a tool preparation area along the Y-axis. The tool magazine is mounted in the tool preparation area through a rigid support structure. The worktable is movably disposed on the base along the Y-axis and arranged between the columns on both sides, so that the tool magazine moves synchronously along the Y-axis with the worktable.

[0011] In this technical solution, the tool magazine is installed in the tool preparation area of ​​the worktable with the aid of a rigid support structure. The worktable can move along the Y-axis and is located between the two columns, so that the tool magazine moves synchronously with the worktable along the Y-axis. This integrates the tool magazine and the worktable, eliminating the need for a separate drive structure for the tool magazine, saving power, and ensuring the synchronicity of their movements. In addition, the worktable is located between the columns, effectively utilizing the space between the column spans, making the machine tool structure more compact and reducing the overall footprint, which is in line with the development trend of machine tool integration and miniaturization.

[0012] The processing area is arranged near the first end of the base, and the tool preparation area is arranged near the second end of the base. The first end and the second end are opposite ends in the Y-axis direction, and the spindle is located on the side of the crossbeam facing the first end.

[0013] In this technical solution, the machining area and the tool preparation area are positioned along the Y-axis, with the spindle located on the side of the crossbeam facing the first end of the base. This layout ensures that during machining, the machining area of ​​the worktable is arranged as close to the spindle as possible, while the tool preparation area is kept as far away from the spindle as possible during machining operations. The machining area can precisely coordinate with the spindle, and the tool magazine in the tool preparation area will not interfere with the machining operation. When a tool change is required, the worktable can be moved to allow the tool magazine to quickly reach below the spindle, optimizing the spatial layout for machining and tool changing and improving the convenience of operation.

[0014] When the worktable moves, the tool magazine can move through the area between the two columns to the outside of the columns; when the worktable moves toward the first end to the end of the Y-axis travel, the tool magazine is located directly below the spindle; when the worktable moves toward the second end to the end of the Y-axis travel, the tool magazine is located in the area between the two columns or on the side of the columns away from the spindle.

[0015] In this technical solution, the position of the tool magazine is defined when the worktable is at the end of different Y-axis travels. When the worktable moves to the foremost point of the Y-axis travel (first end), the tool magazine is located directly below the spindle, which facilitates direct tool changing by the spindle. When it moves to the end of the Y-axis travel (second end), the tool magazine is located between the columns or away from the spindle, avoiding interference with the machining process. The position of the tool magazine in different working states is reasonably planned to ensure smooth machining and tool changing processes.

[0016] The machine tool structure also includes a protective cover that covers the tool magazine. The protective cover is fixedly installed in the tool preparation area and moves synchronously with the worktable.

[0017] In this technical solution, the protective cover can protect the tool magazine, preventing debris, coolant, and other contaminants generated during machining from damaging the tool magazine or affecting tool accuracy. At the same time, the protective cover moves synchronously with the worktable, without affecting the normal operation and position changes of the tool magazine, thus improving the tool magazine's service life and operational stability.

[0018] The top and / or side of the protective cover are provided with a tool changing window, and a protective door for opening or closing the tool changing window is installed on the protective cover.

[0019] In this technical solution, the design of the tool changing window and the protective door allows the protective door to open during tool changing, facilitating tool exchange between the spindle and the tool magazine; after the tool changing is completed, the protective door closes to continue protecting the tool magazine, ensuring both the feasibility of the tool changing operation and enhancing the integrity of the protective cover.

[0020] The rigid support structure includes support frames symmetrically arranged on both sides of the tool preparation area. The bottom of the support frame is fixedly connected to the worktable, and the top of the support frame is fixedly connected to the tool magazine.

[0021] In this technical solution, the rigid support structure adopts support frames symmetrically arranged on both sides of the tool preparation area. The bottom is fixed to the worktable and the top is fixed to the tool magazine. This symmetrical structure can provide stable and balanced support for the tool magazine, preventing the tool magazine from tilting or shaking when moving with the worktable or during operation, thus ensuring the accuracy of the tool magazine position and the stability of the structure.

[0022] The support frame includes a vertical section and a diagonal brace section from bottom to top, and the diagonal brace section is inclined towards the center of the tool magazine.

[0023] In this technical solution, the inclined support section of the support frame is tilted towards the center of the tool magazine, further enhancing the rigidity and stability of the support structure. The inclined support force can better resist the weight of the tool magazine itself and the inertial force generated during movement, making the connection between the tool magazine and the worktable more secure and reducing the impact of vibration on machining accuracy. In addition, based on the inclined design of the inclined support section, the closer the support frame is to the tool magazine, the smaller its structural size and the less space it occupies. Therefore, it can avoid creating a larger tool changing space near the tool magazine and reduce the risk of interfering with the spindle tool changing process.

[0024] The machine tool structure also includes a drive mechanism disposed on the base, the drive mechanism being used to drive the worktable to move along the Y-axis; the drive mechanism includes a first drive motor and a transmission assembly, the first drive motor being fixed to one end of the base located on the Y-axis, and the transmission assembly extending along the Y-axis and connected to the worktable.

[0025] In this technical solution, the drive mechanism is specifically designed to move the worktable along the Y-axis, providing power for the synchronous movement of the worktable and tool magazine. This ensures that the worktable can move precisely to the appropriate position according to the needs of machining and tool changing, guaranteeing the normal operation of the entire machine tool workflow. The first drive motor is fixed at one end of the Y-axis of the base, and the transmission assembly extends along the Y-axis to connect to the worktable. This drive method has a reasonable layout, effectively transmitting power and making the movement of the worktable smoother and more precise. At the same time, the arrangement of the motor and transmission assembly does not occupy too much space, which is conducive to the compactness of the overall machine tool structure.

[0026] The tool magazine includes a tool magazine base, a tool disc, and a second drive motor. The rigid support structure fixes the tool magazine base, and the tool disc is rotatably mounted on the top of the tool magazine base. The tool disc is provided with multiple tool positioning fixtures along its circumference. The second drive motor is mounted on the tool magazine base and is used to drive the tool disc to rotate.

[0027] In this technical solution, the tool magazine itself includes a tool magazine base, a tool disc, a second drive motor, and other structures. The tool positioning fixture on the tool disc can fix multiple tools. The second drive motor drives the tool disc to rotate, which can realize the position switching of different tools, meet the machine tool's needs for using multiple tools, and enable the tool magazine to have independent tool storage and switching functions. In conjunction with the movement of the worktable, it realizes efficient tool changing operation and improves the machining efficiency of the machine tool.

[0028] The machine tool machining center provided in this application includes a machine tool structure integrating the worktable and tool magazine as described above, and has the effects of the integrated structure, which will not be elaborated here. Attached Figure Description

[0048] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0049] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0050] Furthermore, it should be understood in the description of this application that the terms "upper," "lower," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," "lateral," and "longitudinal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0053] In the embodiments of this application, reference is made to Figures 1 to 5As shown, a machine tool structure integrating a worktable and a tool magazine is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, the machine tool structure includes a base 1, columns 2 fixed on both sides of the base 1, a crossbeam 3 connected to the top of the columns 2 on both sides, and a spindle 4 installed on the crossbeam 3. It also includes a worktable 5 and a tool magazine 6. The worktable 5 is divided into a machining area 51 and a tool preparation area 52 along the Y-axis. The tool magazine 6 is installed in the tool preparation area 52 through a rigid support structure. The worktable 5 is movably set on the base 1 along the Y-axis and arranged between the columns 2 on both sides, so that the tool magazine 6 moves synchronously with the worktable 5 along the Y-axis. Figure 1 The Y-axis direction is indicated by a double-headed arrow Y.

[0055] This application improves or solves the defects of two traditional layouts: First, the tool magazine 6 is integrated into the worktable 5 and located between the columns 2, avoiding the problem of increased machine tool width caused by side layout. The machine tool structure is more compact, which can significantly reduce the workshop floor space in actual production, conforming to the development trend of machine tool integration and miniaturization, increasing the equipment capacity per unit space, and reducing site rental costs. Second, the tool magazine 6 does not require an independent drive structure and moves only through the drive of the worktable 5, reducing at least one drive mechanism and control system, saving power sources, reducing not only the cost of parts procurement and assembly, but also reducing failure points and improving equipment reliability. At the same time, the synchronous movement of the tool magazine 6 with the worktable 5 ensures precise matching of the positions of the tool magazine 6 and the worktable 5, avoiding the synchronization error of the traditional independently driven tool magazine 6. In actual machining, it can reduce tool change delays caused by positional deviations and improve production continuity.

[0056] It should be noted that the "workbench" mentioned in this application does not refer only to a single table structure that directly supports the workpiece. It can be the entire workbench with load-bearing function, or the basic load-bearing part of the workbench (such as the workbench base). Specifically, in the technical solution of this application, the workbench 5 is divided into a machining area 51 and a tool preparation area 52 along the Y-axis. The machining area 51, as the core area for workpiece machining, can be separately equipped with a detachable or adjustable machining table structure (such as a fixture mounting plate for clamping workpieces, a replaceable positioning table, etc.) according to actual machining needs. This machining table structure is fixed to the machining area 51 of the workbench 5 by bolt connection, guide rail cooperation, etc., to achieve synchronous movement with the workbench 5. The tool preparation area 52 is used to install the tool magazine 6 through a rigid support structure, and together with the machining area 51, it forms the overall load-bearing frame of the workbench 5. The advantages of this design are twofold: First, the machining area 51 can flexibly adapt to workpieces of different sizes and shapes through a separately designed machining table structure, improving the machine tool's adaptability to diverse machining needs. Second, the overall frame of the worktable 5 provides a unified load-bearing foundation for the machining area 51 and the tool preparation area 52, ensuring the stability and positional accuracy of the machining table and tool magazine 6 as they move synchronously along the Y-axis with the worktable 5, avoiding motion errors caused by the separate design. In short, the "worktable" of this application is an integrated load-bearing platform. Its core function is to achieve coordinated operation of machining and tool preparation through a partitioned design, and the specific load-bearing form of the machining area 51 can be flexibly adjusted according to the actual application scenario, and is not limited to a single fixed table.

[0057] In a preferred embodiment, the worktable 5 can be connected to the base 1 via a guide rail slider mechanism, improving the reliability of the worktable 5's movement. Specifically, as shown... Figure 2 As shown, a slider 7 can be fixedly installed at the bottom of the worktable 5, and a guide rail 8 extending along the Y-axis to both ends of the base 1 is provided on the base 1.

[0058] As a preferred embodiment of this application, such as Figure 2 and Figure 3As shown, the machining area 51 is arranged near the first end 11 of the base 1, and the tool preparation area 52 is arranged near the second end 12 of the base 1. The first end 11 and the second end 12 are opposite ends in the Y-axis direction. The spindle 4 is located on the side of the crossbeam 3 facing the first end 11. This layout ensures that during machining, the machining area 51 of the worktable 5 is arranged as close as possible to the spindle 4, and during machining operations, the tool preparation area 52 is kept as far away from the spindle 4 as possible. The machining area 51 can precisely cooperate with the spindle 4, and the tool magazine 6 of the tool preparation area 52 will not interfere with the machining operation. When a tool change is required, the worktable 5 can be moved so that the tool magazine 6 can quickly reach below the spindle 4, which optimizes the spatial layout of machining and tool changing and improves the convenience of operation. In practical use, during machining, the machining area 51 of the worktable 5 is located directly below the spindle 4, and the tool magazine 6 of the tool preparation area 52 is far away from the machining area 51, avoiding interference between the tool magazine 6 and the workpiece and the spindle 4. When changing tools, the worktable 5 can be moved to the first end 11 to bring the tool magazine 6 closer to the spindle 4 without the need for the spindle 4 to move a long distance, reducing tool changing time and improving batch production efficiency.

[0059] Furthermore, when the worktable 5 moves, the tool magazine 6 can move through the area between the two columns 2 to the outside of the columns 2; when the worktable 5 moves towards the first end 11 to the end of the Y-axis travel, the tool magazine 6 is located directly below the spindle 4; when the worktable 5 moves towards the second end 12 to the end of the Y-axis travel, the tool magazine 6 is located in the area between the two columns 2 or on the side of the columns 2 away from the spindle 4. Figure 1 and Figure 2 The diagram shows the state of the tool magazine 6 within the area between the two columns 2. By limiting the position of the tool magazine 6 at different ends of the Y-axis travel of the worktable 5, when the worktable 5 moves to the foremost end of the Y-axis travel (first end 11), the tool magazine 6 is located directly below the spindle 4, facilitating direct tool changing by the spindle 4; when it moves to the end of the Y-axis travel (second end 12), the tool magazine 6 is located between the columns 2 or away from the spindle 4, avoiding interference with the machining process. The position of the tool magazine 6 in different working states is rationally planned, ensuring smooth machining and tool changing processes. For example, during milling and drilling operations, the tool magazine 6 does not occupy the machining area 51, allowing the worktable 5 to move the workpiece within a wider range, meeting the machining needs of large workpieces. Simultaneously, the design that allows the tool magazine 6 to move to the outside of the columns 2 not only facilitates tool changing by moving it below the spindle 4, but also allows operators to change tools or maintain the tool magazine 6 when not machining, without needing to enter the machine tool, thus improving operational safety.

[0060] As a preferred embodiment of this application, such as Figure 3 and Figure 4As shown, the machine tool structure also includes a protective cover 9 covering the tool magazine 6. The protective cover 9 is fixedly installed in the tool preparation area 52 and moves synchronously with the worktable 5. In actual machining, metal chips (especially cast iron and aluminum alloy chips) generated during milling may splash into the tool magazine 6, causing a decrease in tool positioning accuracy; if coolant seeps into the transmission components of the tool magazine 6, it will accelerate the corrosion of gears and bearings. Therefore, the protective cover 9 can protect the tool magazine 6, preventing chips, coolant, etc. generated during machining from damaging the tool magazine 6 or affecting tool accuracy, thus extending the service life of the tool magazine 6. In addition, the protective cover 9 moves synchronously with the worktable 5, and its protective effect will not be affected by changes in position. For example, when the worktable 5 moves rapidly, the protective cover 9 always tightly covers the tool magazine 6, avoiding protection failure and improving the service life and working stability of the tool magazine 6. In a preferred embodiment, the bottom of the protective cover 9 can be fixedly installed on the side of the worktable 5 with screws.

[0061] Furthermore, such as Figure 3 and Figure 4 As shown, the protective cover 9 is provided with a tool changing window 91, and a protective door 10 for opening or closing the tool changing window 91 is installed on the protective cover 9; in a preferred embodiment, the tool changing window 91 can be provided on the top or side of the protective cover 9, or as shown in the figure. Figure 4 The shield 9 extends from its top to its side. The design of the tool change window 91 and the protective door 10 allows the protective door 10 to open during tool changes, facilitating tool exchange between the spindle 4 and the tool magazine 6. For example, as mentioned earlier, when the worktable 5 moves to the foremost point of its Y-axis travel (first end 11), the tool magazine 6 is directly below the spindle 4. At this time, the protective door 10 can be in the open tool change window 91 state, allowing the spindle 4 to change tools through the tool change window 91. After the tool change is completed, the protective door 10 closes, isolating the tool magazine 6 from the machining area 51 and continuing to protect the tool magazine 6. This ensures the feasibility of tool changing operations and enhances the integrity of the shield 9's protection. In actual use, the protective door 10 can be driven to open and close using pneumatic, electric, or other suitable methods to achieve automated control, reduce manual intervention, and improve the continuity of the tool changing process.

[0062] As a preferred embodiment of this application, such as Figure 3 and Figure 5As shown, the rigid support structure includes support frames 20 symmetrically arranged on both sides of the tool preparation area 52. The bottom of the support frames 20 is fixedly connected to the worktable 5, and the top of the support frames 20 is fixedly connected to the tool magazine 6. Those skilled in the art will understand that in actual use, the tool magazine 6 has a relatively large weight (for example, most of the time it contains more than 20 tools, weighing several hundred kilograms). When it moves with the worktable 5, it generates inertial force. Therefore, in this solution, the rigid support structure uses support frames 20 symmetrically arranged on both sides of the tool preparation area 52, with the bottom fixed to the worktable 5 and the top fixed to the tool magazine 6. This symmetrical structure can balance the forces on both sides, providing stable and balanced support for the tool magazine 6, preventing the tool magazine 6 from tilting or swaying during movement with the worktable 5 or during operation, thus ensuring the accuracy of the tool magazine 6's position and the stability of the structure.

[0063] Furthermore, such as Figure 5 As shown, the support frame 20 includes a vertical section 201 and a diagonal support section 202 from bottom to top. The diagonal support section 202 is inclined towards the center of the tool magazine 6. The vertical section 201 bears the vertical weight of the tool magazine 6, while the diagonal support section 202, inclined towards the center of the tool magazine 6, further enhances the rigidity and stability of the support structure. The diagonal support force can better resist the weight of the tool magazine 6 itself and the inertial force generated during movement, making the connection between the tool magazine 6 and the worktable 5 more secure and reducing the impact of vibration on machining accuracy. In addition, based on the inclined design of the diagonal support section 202, the closer the support frame 20 is to the tool magazine 6, the smaller its structural size and the less space it occupies. Therefore, it can provide more space for tool changing near the tool magazine 6, reducing the risk of interfering with the tool changing process of the spindle 4. This structure also reduces the overall height of the support frame 20, lowers the center of gravity of the tool magazine 6, and improves the stability of the worktable 5 during movement, making it particularly suitable for high-speed machining scenarios.

[0064] In a preferred embodiment of this application, the machine tool structure further includes a drive mechanism mounted on the base 1. The drive mechanism is used to drive the worktable 5 to move along the Y-axis. The drive mechanism is specifically designed to drive the worktable 5 to move along the Y-axis, providing power for the synchronous movement of the worktable 5 and the tool magazine 6. This ensures that the worktable 5 can be precisely moved to the corresponding position according to the needs of machining and tool changing, thus guaranteeing the normal operation of the entire machine tool workflow.

[0065] In a preferred embodiment, such as Figure 1As shown, the drive mechanism includes a first drive motor 30 and a transmission assembly. The first drive motor 30 is fixed to one end of the base 1 along the Y-axis, and the transmission assembly extends along the Y-axis and connects to the worktable 5. This drive configuration is reasonable, effectively transmitting power and making the movement of the worktable 5 smoother and more precise. Simultaneously, the motor and transmission assembly do not occupy excessive space, contributing to the compactness of the overall machine tool structure. The attached figure shows an embodiment where the first drive motor 30 is located at the second end 12 of the base 1, away from the machining area 51, thus avoiding corrosion from coolant and debris. The transmission assembly is not shown in the figure, but it can be a ball screw, linear guide, or other similar structure.

[0066] In alternative embodiments, the drive mechanism may also be a linear motor, hydraulic drive, pneumatic drive, or other structural forms.

[0067] As a preferred embodiment of this application, such as Figure 5 As shown, the tool magazine 6 includes a tool magazine base 61, a tool disc 62, and a second drive motor 63. A rigid support structure fixes the tool magazine base 61. The tool disc 62 is rotatably mounted on the top of the tool magazine base 61. Multiple tool positioning fixtures 64 are arranged circumferentially on the tool disc 62. The second drive motor 63 is mounted on the tool magazine base 61 and is used to drive the tool disc 62 to rotate. The tool magazine 6 itself includes the tool magazine base 61, the tool disc 62, the second drive motor 63, and other structures. The tool positioning fixtures 64 on the tool disc 62 can fix multiple tools and can accommodate tools of the same type but different specifications or different types of tools (such as end mills, drills, and taps), realizing multi-process machining in one clamping. The second drive motor 63 drives the tool disc 62 to rotate, realizing the position switching of different tools. It can quickly rotate the target tool to the tool changing position, meeting the machine tool's needs for using multiple tools. This gives the tool magazine 6 independent tool storage and switching functions. In conjunction with the movement of the worktable 5, it realizes efficient tool changing operations and improves the machining efficiency of the machine tool.

[0068] The machine tool machining center provided in this application includes the machine tool structure integrating the worktable and tool magazine as described above.
