Description

Technical Field

[0001] This invention relates to the technical field of fixed beam gantry machining centers, specifically a high-precision fixed beam gantry machining center. Background Technology

[0002] A fixed-beam gantry machining center is a machining center in which the spindle axis is set perpendicular to the worktable. The overall structure is a gantry frame, consisting of double columns and a top beam, with a crossbeam in the middle. The crossbeam on the gantry frame is fixed and has multiple machining functions such as milling, boring, drilling (drilling, reaming, and boring), tapping, and countersinking. It is mainly used in machining, automotive mold making, and aerospace industries.

[0003] When machining workpieces in a fixed-beam gantry machining center, the resulting chips fall directly onto the machining platform. When the chips accumulate to a certain amount, they need to be cleaned. Current technology typically involves manual removal of the chips bit by bit using tools like shovels. This is not only time-consuming and labor-intensive but also inefficient. If not cleaned, the accumulated chips on the machining platform will affect the subsequent normal processing and operation of the fixed-beam gantry machining center. Furthermore, the accumulated chips can be blown onto the ground by the wind, affecting the working environment.

[0004] Therefore, it is necessary to provide a high-precision fixed-beam gantry machining center to solve the above problems. Summary of the Invention

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention, by setting an adjustment component, uses a drive motor to drive gear one, gear two, and gear three in a linkage to drive the coolant pipe to rotate at multiple angles, thereby realizing real-time dynamic adjustment of the cooling angle in the tool processing area. At the same time, by using three sets of limiting parts in cooperation with the swing rod, the bending state of the hose is automatically adjusted while adjusting the cooling angle, avoiding pipe interference or sagging. This solves the pain point of traditional fixed cooling pipes being easy to entangle or affecting processing accuracy, and realizes the self-adaptive limiting of the pipe.

[0028] By incorporating cleaning components one and two, when the cleaning plate encounters resistance, spring one is compressed, pushing the blockage in the movable oil port to move. The coolant flow rate is automatically adjusted according to the resistance level, achieving a self-adaptive flushing effect where the greater the resistance, the greater the flow rate. Simultaneously, by utilizing the cleaning resistance data monitored in real time by the pressure sensor when the cleaning plate encounters resistance, combined with the total count threshold and continuous count threshold, the cleaning difficulty is intelligently determined, triggering different cleaning modes. Furthermore, during continuous processing, the coolant spray direction can be adjusted to actively guide the dispersion of debris, preventing local accumulation and reducing manual intervention while improving the efficiency of continuous processing.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1-11 The present invention provides a technical solution: a high-precision fixed-beam gantry machining center, comprising a base 1, a worktable 3, a machining mechanism 6, and a cleaning mechanism 7. The worktable 3 is located at the top center of the base 1 and is slidably connected to the base 1. A drive unit 31 is fixedly installed inside the base 1. The drive unit 31 is driven by a motor and screw, and is connected to the worktable 3. The drive unit 31 is used to drive the worktable 3 to slide on the top of the base 1. The machining mechanism 6 is located above the base 1. The top of the worktable 3 is provided with several chip removal grooves. The chip removal grooves are used for chip removal, facilitating coolant flow and absorbing machining vibration. The cleaning mechanism 7 is located on the top of the worktable 3. The machining mechanism 6 is used to process the workpiece on the worktable 3, and the cleaning mechanism 7 is used to clean the debris from the worktable 3 after the workpiece is processed.

[0047] Specifically, such as Figure 1 As shown, two sets of telescopic guards 2 are slidably connected to the top of the base 1. The two sets of telescopic guards 2 are located on both sides of the workbench 3, and the side of the two sets of telescopic guards 2 closest to the workbench 3 is fixedly connected to the workbench 3.

[0048] Specifically, such as Figure 1 and Figure 2 As shown, chip discharge ports 32 are provided on both sides of the workbench 3. The chip discharge ports 32 are inclined and are used to discharge chips and coolant. The chip discharge ports 32 are connected to a coolant tank.

[0049] It should be noted that, for easier display of the internal structure of base 1, Figure 1 The telescopic protective cover 2 on the left side is not connected to the workbench 3.

[0050] Specifically, such as Figure 1 and Figure 2 As shown, two columns 4 are respectively provided on both sides of the base 1. The direction of the two sets of columns 4 is perpendicular to the direction of the base 1. A transverse frame 5 is fixedly connected to the top of the two sets of columns 4. The processing mechanism 6 is slidably arranged on the side of the transverse frame 5.

[0051] Specifically, such as Figures 3-6As shown, the processing mechanism 6 includes a transverse base 61, a drive motor 66, a spindle 67, and an adjustment assembly 69. The transverse base 61 is slidably disposed on the side of the transverse frame 5. A drive unit 62 is fixedly connected to the side of the transverse frame 5. The drive unit 62 is driven by the transverse base 61. A lifting seat 63 is slidably connected to the side of the transverse base 61. A drive unit 64 is fixedly connected to the top of the transverse base 61. The drive unit 64 is driven by the lifting seat 63. Both the drive unit 62 and the drive unit 64 can be driven by a motor screw, or other structures that can drive the lifting seat 63 to slide on the side of the transverse base 61 and the transverse base 61 to slide on the side of the transverse frame 5. The drive unit 62 is used to drive the transverse base 61 to slide along the setting direction of the transverse frame 5. The drive unit 64 is used to drive the lifting seat 63 to slide up and down on the side of the transverse base 61.

[0052] like Figures 4-6 As shown, a spindle box 65 is fixedly connected to the lower side of the lifting seat 63. A drive motor 66 is fixed to the top of the spindle box 65. The spindle 67 is connected to the bottom bearing of the spindle box 65. The output end of the drive motor 66 is connected to the pulley of the spindle 67. A tool 68 is connected to the bottom of the spindle 67. The drive motor 66 is used to drive the spindle 67 to rotate, thereby driving the tool 68 to rotate, so as to realize the processing of the workpiece to be processed.

[0053] The adjustment assembly 69 is located at the bottom of the spindle box 65. The adjustment assembly 69 includes a first gear 692, a second gear 693, a third gear 694, a first coolant pipe 696, a second coolant pipe 697, three sets of limiting parts 698, and a rocker arm 699. A rotating track 691 is fixedly connected to the bottom of the spindle box 65. The rotating track 691 is located around the spindle 67. The first gear 692 is rotatably connected to the bottom of the rotating track 691.

[0054] The bottom of the spindle box 65 is provided with a slot 6912, which is located on the left side of the spindle 67. The drive motor 6910 is installed inside the slot 6912. The bottom of the spindle box 65 is connected to a connecting plate 6911. The drive motor 6910 is fixed to the top of the connecting plate 6911. The output end of the drive motor 6910 passes through the connecting plate 6911 and is fixedly connected to a gear 693. The bottom bearing of the drive motor 6910 is connected to a gear 694. Gears 692, 693, and 694 are arranged sequentially from left to right. Gear 692 meshes with gear 693, and gear 693 meshes with gear 694.

[0055] A fixing plate 695 is fixedly connected to the bottom of gear 1 692 near gear 2 693. Coolant pipe 1 696 is fixed to the bottom of fixing plate 695. Coolant pipe 1 696 is connected to coolant pipe 2 697. Coolant pipe 1 696 is positioned towards the cutter 68. A nozzle is provided at the end of coolant pipe 1 696 near the cutter 68.

[0056] It should be noted that coolant pipe 696 is preferably made of rigid material, while coolant pipe 697 is preferably made of flexible material, which facilitates the adjustment of the angle of coolant pipe 696 and the subsequent length adjustment of coolant pipe 697.

[0057] The limiting part 698 includes a fixed seat 6981, a rotating seat 6982, two sets of limiting posts 6983, and a connecting seat 6984. The rotating seat 6982 is rotatably connected to the bottom of the fixed seat 6981. The two sets of limiting posts 6983 are located between the rotating seat 6982 and the connecting seat 6984. The two ends of the limiting posts 6983 are rotatably connected to the rotating seat 6982 and the connecting seat 6984, respectively. Thus, the rotating seat 6982, the two sets of limiting posts 6983, and the connecting seat 6984 can form a limiting area, which facilitates the limiting of the coolant pipe 697.

[0058] It should be noted that the distance between the two sets of rotating seats 6982 is greater than the diameter of the coolant pipe 697, and the distance between the fixed seat 6981 and the connecting seat 6984 is greater than the diameter of the coolant pipe 697. Therefore, the existing limiting area of ​​the limiting part 698 only limits the coolant pipe 697 and does not fix or clamp the coolant pipe 697.

[0059] A connecting block 6913 is fixedly connected to the bottom of the spindle box 65 on the side away from the rotating track 691. A rocker arm 699 is fixedly connected to the bottom of the gear 3 694. Three sets of limiting parts 698 are respectively fixed to the bottom center of the gear 2 693, the bottom center of the gear 3 694 and the bottom of the connecting block 6913. That is, the fixing seat 6981 in the limiting part 698 is fixed to the bottom center of the gear 2 693, the bottom center of the gear 3 694 and the bottom of the connecting block 6913. The coolant pipe 2 697 passes through the two sets of limiting posts 6983 in the three sets of limiting parts 698 in sequence.

[0060] In actual operation, the second drive unit 62 starts to drive the transverse moving seat 61 to move left and right along the setting direction of the transverse moving frame 5 on the transverse moving frame 5, the third drive unit 64 starts to drive the lifting seat 63 to move up and down on the side of the transverse moving seat 61, and the fourth drive motor 66 starts to drive the spindle 67 to rotate through the belt pulley drive, thereby driving the tool 68 to rotate and process the workpiece to be processed.

[0061] like Figure 4As shown, in the initial state, the three sets of limiting parts 698 are staggered, and the setting direction of the swing arm 699 is perpendicular to the setting direction of the two sets of limiting parts 698 located on both sides of the swing arm 699. That is, there is an angle between the coolant pipes 697 located on the three sets of limiting parts 698. When it is necessary to adjust the cooling angle of the coolant pipe 696 aligned with the tool 68 or to adjust the flushing angle of the coolant pipe 696, the drive motor 6910 starts to rotate clockwise, driving the gear 693 to rotate clockwise. Through the meshing of the gear 693 and the gear 692, the gear 692 is driven to rotate counterclockwise, synchronously driving the fixed plate 695 to rotate, thereby adjusting the angle of the coolant pipe 696 aligned with the tool 68. Since the coolant pipe 696 is fixed to the bottom of the fixed plate 695, the coolant pipe 697 is connected to the coolant pipe 696. The coolant pipe 697 is sequentially arranged on the three sets of limiting parts. On 698, when the fixed plate 695 rotates, the distance between the fixed plate 695 and the bottom limiting part 698 of the gear 2 693 increases, which pulls the coolant pipe 2 697. At the same time, the meshing of the gear 2 693 and the gear 3 694 drives the gear 3 694 to rotate counterclockwise, which in turn drives the bottom center rocker arm 699 of the gear 3 694 to rotate counterclockwise. This increases the angle between the coolant pipe 2 697 on the bottom limiting part 698 of the rocker arm 699 and the other two sets of limiting parts 698, making the coolant pipe 2 697 on the three sets of limiting parts 698 tend to be straight and reducing the actual length of the coolant pipe 2 697 between the three sets of limiting parts 698. This can cooperate with the pulling of the coolant pipe 2 697 when the fixed plate 695 rotates. Thus, through the above structure, the problem of the coolant pipe 2 697 sagging is avoided, thereby ensuring the normal operation of the processing cooling.

[0062] Similarly, in the initial state, when the drive motor 6910 starts to rotate counterclockwise, it can also adjust the cooling angle of the coolant pipe 696 aligned with the tool 68 or adjust the flushing angle of the coolant pipe 696. The working principle is the same as when the drive motor 6910 starts to rotate clockwise.

[0063] It should be noted that, in order to ensure that the cooling angle of the first coolant pipe 696 is aligned with the tool 68 or that the flushing angle of the first coolant pipe 696 is adjusted, the second coolant pipe 697 will not affect the normal machining of the tool 68. In the initial state, the first drive motor 6910 can only rotate clockwise and counterclockwise by a limited angle, usually not exceeding 90°. The second coolant pipe 697 is connected to the coolant tank, and the coolant tank is equipped with a filter mechanism to remove impurities that enter the coolant tank.

[0064] Specifically, such as Figure 2 , Figures 7-11As shown, the cleaning mechanism 7 includes two sets of drive motors 71, an oil storage frame 73, several cleaning components 75, and two sets of cleaning components 76. The oil storage frame 73 is slidably mounted on the top of the workbench 3. Two sets of equipment frames 78 are fixedly connected to the side of the oil storage frame 73. The drive motors 71 are located inside the equipment frames 78. Two sets of transmission frames 72 are fixedly connected to both sides of the workbench 3 along the direction of the transverse frame 5. The transmission frames 72 have openings on the side facing the workbench 3. The position and size of the openings correspond to the position and size of the output end of the drive motors 71. The output end of the drive motors 71 is connected to the transmission frames 72 by a gear and rack transmission. The gear is fixed to the output end of the drive motors 71, and the rack is fixed inside the transmission frames 72. When the drive motors 71 are started, they drive the oil storage frame 73 to move back and forth on the top of the workbench 3 along the direction of the base 1 through the gear and rack transmission.

[0065] like Figures 7-9 As shown, the oil storage frame 73 is provided with an oil storage area 731, a transmission area 732 and an equipment area 733. The oil storage area 731 and the transmission area 732 are arranged vertically. An inlet pipe 74 is provided on the side of the oil storage frame 73, and the position of the inlet pipe 74 corresponds to that of the oil storage area 731. The inlet pipe 74 is connected to the coolant tank. The equipment area 733 is located on the side of the oil storage area 731 away from the inlet pipe 74. A drive motor 77 is provided inside the equipment area 733.

[0066] like Figures 7-9 As shown, the second cleaning component 76 and the first cleaning component 75 have the same shape as the chip removal groove on the top of the workbench 3. The two sets of second cleaning components 76 are located on both sides of the several sets of first cleaning components 75. The output end of the third drive motor 77 is connected to the several sets of first cleaning components 75 and the two sets of second cleaning components 76 through a pulley drive. The first cleaning component 75 and the second cleaning component 76 are connected to the bearing of the oil storage frame 73. The pulley drive connection part is located in the transmission area 732. The third drive motor 77 is started to drive the several sets of first cleaning components 75 and the two sets of second cleaning components 76 to rotate synchronously and in the same direction to adjust the cleaning range.

[0067] Furthermore, such as Figures 10-11 As shown, the cleaning component 75 includes an oil storage box 751, two sets of cleaning plates 753, several extrusion parts 756, and a pressure sensor 757. The oil storage box 751 is connected to the oil storage frame 73 by a bearing. The oil storage box 751 is connected to the output end of the drive motor 77 via a pulley drive. The oil storage box 751 has grooves on both sides, and several springs 752 are installed in the grooves. The two ends of the springs 752 are fixedly connected to the oil storage box 751 and the cleaning plates 753 respectively. The cleaning plates 753 are installed in the grooves and are slidably connected to the oil storage box 751. Several liquid outlets 754 are provided on the cleaning plates 753. A limiting groove 7541 is provided on the side of the cleaning plates 753 near the oil storage box 751. The limiting groove 7541 is located on both sides of the liquid outlets 754 and communicates with the liquid outlets 754.

[0068] Several movable oil ports 755 are fixedly connected to both sides of the oil storage box 751. Pressure sensors 757 are fixed to both sides of the oil storage box 751. The outer wall of the movable oil port 755 is provided with a slope. The position of the movable oil port 755 corresponds to the liquid outlet 754. The outer diameter of the movable oil port 755 matches the inner diameter of the liquid outlet 754. Sliding grooves 7551 are horizontally provided on both sides of the movable oil port 755. Pressure sensors 757 are electrically connected to a pressure acquisition module. The pressure acquisition module is used to collect the pressure when the cleaning component 75 cleans the debris inside the chip removal groove.

[0069] The extrusion section 756 is disposed within the movable oil port 755. The extrusion section 756 includes a connecting frame 7561, two sets of springs 7562, and a blocking block 7563. The connecting frame 7561 is U-shaped, with both ends of the connecting frame 7561 located within the sliding groove 7551. The outer wall of the connecting frame 7561 fits against the inner diameter of the movable oil port 755. The connecting frame 7561 is slidably connected to the movable oil port 755. The limiting groove 7541 matches the position and size of the connecting frame 7561. The two ends of the springs 7562 are fixedly connected to the connecting frame 7561 and the oil storage box 751, respectively. The blocking block 7563 is disposed inside the oil storage box 751. The blocking block 7563 matches the inner diameter of the movable oil port 755. The limiting groove 7541 and the sliding groove 7551 are used to limit the position of the connecting frame 7561.

[0070] It should be noted that the cleaning component 2 76 has the same structure and the same internal connection method as the cleaning component 1 75, but the number of structures and the overall shape are different; the drive motor 3 77 starts and drives the cleaning component 1 75 and the cleaning component 2 76 to rotate at an angle of less than 90°; the oil storage box 751 and the cleaning component 2 76 have hollow internal structures.

[0071] The bottom of the cleaning plate 753 can completely cover the top of the cleaning component 1 75 and the cleaning component 2 76, thereby preventing debris from entering between the cleaning plate 753 and the oil reservoir 751, thus avoiding affecting the flow of coolant and the effect of pressure detection.

[0072] In actual operation, the initial state of the cleaning mechanism 7 is that the oil storage frame 73 is located at one end of the top of the workbench 3, and the block 7563 seals the movable oil port 755 inside the oil storage box 751, so the coolant cannot flow out from the equipment area 733. When it is necessary to clean the top of the workbench 3, the second drive motor 71 is started, driving the oil storage frame 73 to move back and forth on the top of the workbench 3 along the setting direction of the base 1, so that the first cleaning component 75 and the second cleaning component 76 clean the processing chips inside the chip removal groove. When the amount of chips is large or adheres to the inside of the chip removal groove, the cleaning plate 75... The increased cleaning difficulty of part 3, i.e., greater resistance, causes the cleaning plate 753 to move towards the oil reservoir 751 relative to it, compressing the spring 752. At the same time, the cleaning plate 753 presses the connecting frame 7561, causing the connecting frame 7561 to move towards the oil reservoir 751 within the slide groove 7551. This releases the blockage block 7563 from the inside of the movable oil port 755, allowing the coolant inside the oil reservoir 751 to flow out through the movable oil port 755 and the outlet 754, flushing and lubricating the accumulated area, thus reducing the resistance and difficulty of cleaning.

[0073] When the resistance is high, the cleaning plate 753 moves a large distance, and the squeezing connecting frame 7561 drives the block 7563 to move a large distance into the oil reservoir 751, so that the cleaning plate 753 can completely release the blockage of the movable oil port 755, and a large amount of coolant can flow out from inside the cleaning plate 753, resulting in a significant flushing effect. When the resistance is low, the cleaning plate 753 moves a small distance, and the squeezing connecting frame 7561 drives the block 7563 to move a small distance into the oil reservoir 751, so the cleaning plate 753 does not completely release the blockage of the movable oil port 755, and a small amount of coolant can flow out from inside the cleaning plate 753, resulting in a less significant flushing effect, but it can still reduce the cleaning difficulty. Therefore, the cleaning component 75 can adjust the coolant flow rate according to the cleaning difficulty.

[0074] When the cleaning plate 753 encounters resistance, it can compress the spring 752 and also squeeze the pressure sensor 757. The pressure sensor 757 can obtain the pressure during squeezing, thereby further judging the overall cleaning difficulty. When the overall cleaning difficulty is high, the drive motor 77 can be started by controlling the drive motor 77 to drive the cleaning component 75 and the cleaning component 76 to rotate, adjust the actual cleaning range, and avoid damage to the equipment due to high cleaning resistance.

[0075] like Figure 1 and Figure 2 As shown, an operating table 8 is fixedly connected to the top of the transverse frame 5. The operating table 8 is connected to the pressure acquisition module for signal connection. The operating table 8 is used to set and display processing parameters. The operating table 8 is electrically connected to the worktable 3, the processing mechanism 6, and the cleaning mechanism 7.

[0076] Working method of high-precision fixed beam gantry machining center:

[0077] Step 1: Clamp the workpiece to be processed on the top of the worktable 3 and process the workpiece. At the same time, control the coolant to flow into the coolant pipe 696 to cool, lubricate and flush the processed part.

[0078] Step 2: Remove the finished workpiece, control the cleaning mechanism 7 to clean the top of the worktable 3, and the pressure acquisition module collects the pressure on cleaning component 1 75 and cleaning component 2 76 during cleaning.

[0079] Specifically, drive motor 71 starts, driving oil storage frame 73 to move back and forth on top of worktable 3 along the setting direction of base 1, so that cleaning components 75 and 76 clean the machining debris inside the chip discharge groove. Pressure sensor 757 can obtain the pressure when cleaning plate 753 is resisted, and the pressure is recorded as f. ij , i∈[1,k], i is the sequence number of cleaning component 1 75 and cleaning component 2 76 arranged from left to right, k is the total number of cleaning component 1 75 and cleaning component 2 76, and also the total number of chip removal slots, j∈[1,2], j takes an integer, j=1 and j=2 represent the pressure data detected by the pressure sensors 757 located on the left and right sides of the oil storage box 751, respectively.

[0080] Step 3: The pressure acquisition module determines the difficulty of cleaning based on the acquired pressure data and adjusts the cleaning method accordingly.

[0081] Specifically, the pressure acquisition module is set with a pressure threshold, F. When f ik >F indicates that the chip removal trough is difficult to clean. At the same time, the pressure acquisition module counts the chip removal troughs with high cleaning difficulty, and the total value is n. For the continuous storage of chip removal troughs with high cleaning difficulty, the maximum continuous count is m.

[0082] The pressure acquisition module also has a total count threshold and a maximum continuous count threshold. The total count threshold is N, and the continuous count threshold is M. N≥M. When n>N, the overall cleaning is difficult. When m>M, the cleaning is difficult for a local area.

[0083] It should be noted that the pressure threshold F is the pressure at which the pressure is released when the cleaning plate 753 is resisted, causing the connecting bracket 7561 to completely release the blockage 7563 from the movable oil port 755.

[0084] Case 1: When n≤N and m≤M, it is the normal situation when the cleaning mechanism 7 is cleaning; when n=0 and m=0, it is the ideal state.

[0085] Scenario 2: When n > N and m ≤ M, due to the difficulty in cleaning the chip removal grooves and the dispersed nature of the cleaning area, the pressure acquisition module feeds back to the control console 8. The control console 8 then controls the drive motor 3 77 to start rotating forward, driving the cleaning components 1 75 and 2 76 to rotate, reducing the actual cleaning range and thus reducing resistance to avoid damaging the equipment. When the drive motor 2 71 drives the oil storage frame 73 to move from one end of the top of the workbench 3 to the other end, the pressure acquisition module feeds back to the control console 8. The control console 8 then controls the drive motor 3 77 to start rotating in reverse, so that the cleaning components 1 75 and 2 76 completely cover the chip removal grooves, re-cleaning the chip removal grooves to ensure complete cleaning.

[0086] Case 3: When n≤N and m>M, the pressure acquisition module feeds back to the control console 8, which then controls the start of drive unit 2 62 and drive unit 3 64. The cutter 68 is adjusted to approach the chip removal groove where there is a localized area that is difficult to clean, and then the drive motor 1 6910 is started. The drive motor 1 6910 rotates, so that the coolant pipe 1 696 can assist in flushing the debris in the chip removal groove where it is difficult to clean, thus achieving the effect of auxiliary cleaning.

[0087] Case 4: When n > N and m > M, Case 2 and Case 3 are carried out simultaneously. This involves flushing and assisting in cleaning the chip removal trough within a local area, while actively reducing the actual cleaning range to avoid damaging the equipment. Furthermore, the number of cleaning cycles is increased to ensure that there are no chip residues or accumulations inside the chip removal trough.

[0088] It should be noted that when the cleaning mechanism 7 cleans the top of the worktable 3 after multiple workpieces have been processed, and situations three and four occur, during normal workpiece processing, the pressure acquisition module feeds back to the control console 8, which then controls the drive motor 6910 to start. The drive motor 6910 rotates and adjusts the angle of the coolant pipe 696 aligned with the tool 68, actively adjusting the flushing direction of the debris generated during processing. This prevents the debris from being flushed in a single reverse direction, which would increase the difficulty of cleaning debris in a localized area.

[0089] The above steps enable the cleaning of debris generated after workpiece machining by the fixed beam gantry machining center, reducing the workload of manual cleaning and preventing debris accumulation and scattering from affecting normal workpiece machining. This, in turn, helps improve the machining accuracy and efficiency of the fixed beam gantry machining center.
