A mobile cutting device for fabricated interior panels for buildings

Abstract

This invention discloses a mobile cutting device for prefabricated interior panels used in construction, relating to the field of interior panel cutting technology. The device includes a mobile cutting unit comprising: a mounting base; and a positioning component mounted on the mounting base. This invention utilizes a U-shaped electric slide rail to drive the cutting saw across both sides of the wall panel's thickness direction, achieving full-thickness through-cutting from one side of the wall panel to the other. This overcomes the geometric limitations of traditional circular saw blades, reducing the material connection area between the corner block and the wall panel body, facilitating the removal of the corner block. Simultaneously, a corner block fracture component is provided, which uses a right-angled fracture support block to convert the linear thrust of the screw drive into a directional fracture force perpendicular to the wall panel. This causes stress concentration along the cutting line in the small residual connection area at the root of the corner, resulting in complete fracture without manual chiseling or prying, completely avoiding damage to the wall panel substrate and chipping of the finish, thus improving the one-time forming qualification rate of the corner cut.

Description

Technical Field

[0001] This invention relates to the field of interior panel cutting technology, specifically to a mobile cutting device for prefabricated interior panels used in construction. Background Technology

[0002] Prefabricated interior panels (such as gypsum board, calcium silicate board, wood and bamboo fiber composite wall panels, etc.) are widely used in interior partition and finishing projects. To accommodate building corners and avoid structural columns and pipelines, L-shaped notches, rectangular grooves, etc., need to be cut at the corners of the wall panels on site to form corner cuts.

[0003] Currently, operators mainly use handheld circular saws to complete this type of cutting, but the following prominent problems exist when cutting inside corners:

[0004] On the one hand, after using a circular saw to cut out the inside corner along the two intersecting cutting lines, due to the geometric characteristics of the circular saw blade, the two cuts cannot be completely connected at the root of the inside corner. A large triangular area that has not been cut off will remain at the root, causing the cut inside corner block to remain connected to the wall panel body, making it difficult to remove the wall block at the inside corner.

[0005] On the other hand, during on-site cutting, the thickness of the wall panel often varies depending on the specifications, making it difficult for a single-size circular saw to be universally applicable. When the maximum cutting depth of the existing circular saw is less than the thickness of the panel, a single cut cannot cut through the thickness in one stroke. It is necessary to cut from both sides of the wall panel separately. This double-sided operation is cumbersome and inefficient. Furthermore, the cutting trajectories of the two sides are prone to misalignment, resulting in misaligned or stepped cuts, affecting the tightness and flatness of the splicing. If a larger radius saw blade is used to cut through the thick panel, although it can cut through in one stroke, as the saw blade radius increases, the uncut triangular area left at the root of the inside corner also expands accordingly, making corner separation more difficult. At the same time, the larger saw blade circular saw is heavier, and its maneuverability is significantly insufficient when cutting the short side of the inside corner. The saw path is difficult to control precisely, resulting in poor processing accuracy and high operating difficulty.

[0006] Therefore, a mobile cutting device for prefabricated interior panels for construction was proposed to solve the above problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a mobile cutting device for prefabricated interior panels used in construction, thereby solving the problems mentioned in the background section.

[0019] Preferably, the cutting distance adjustment assembly includes an adjustment seat fixed on an electric slide rail moving frame, a single threaded screw is rotatably installed inside the adjustment seat, a knob is fixedly connected to one end of the single threaded screw, the single threaded screw can thread-drive the moving seat to slide linearly along the inner side of the adjustment seat, and the moving seat is fixedly connected to the cutting saw.

[0020] Preferably, laser sights are fixedly installed inside the end of the centering rod away from the support rod and on the electric slide rail. Both laser sights are on the same plane as the saw blade of the cutting saw, and the cutting trajectory of the cutting saw can be easily pre-aligned through the two laser sights.

[0021] Preferably, a pointer is fixedly installed on the electric slide rail, and a circumferential scale line is provided at the end of the angle adjustment support frame, and the center of the circumferential scale line corresponds to the rotation center between the angle adjustment support frame and the electric slide rail.

[0022] Preferably, the electric slide rail is equipped with a corner block breaking assembly. The corner block breaking assembly includes a connecting frame fixed in the middle of the electric slide rail. A limit frame is slidably installed on the connecting frame along the straight cutting direction of the cutting saw. A single threaded screw is rotatably installed on the limit frame. A knob is fixedly connected to one end of the single threaded screw. A breaking support block is fixedly installed on the side of the limit frame facing the cutting saw. The breaking support block has a right-angle structure, and the inclined surface of the breaking support block faces the corner wall block to be cut. The single threaded screw is threadedly connected to the connecting frame, which can drive the breaking support block to insert into the cutting gap and squeeze the corner wall block, causing it to break and separate from the wall panel.

The second guide frame is provided with distance scale lines to facilitate direct reading of the spacing between the two cutting saws.

[0024] Compared with the prior art, the present invention provides a mobile cutting device for prefabricated interior panels in construction, which has the following advantages:

[0025] This invention utilizes a U-shaped electric slide rail to drive a cutting saw that spans both sides of the wall panel's thickness direction, enabling full-thickness through-cutting from one side of the wall panel to the other. This overcomes the geometric limitations of traditional circular saw blades, reduces the material connection area between the corner block and the wall panel body, and facilitates the removal of the corner block. Simultaneously, a corner block fracture component is provided, which uses a right-angle fracture support block to convert the linear thrust of the screw drive into a directional fracture force perpendicular to the wall panel. This causes stress concentration along the cutting line in the tiny residual connection area at the root of the corner, resulting in complete fracture without the need for manual chiseling or prying, completely avoiding damage to the wall panel substrate and chipping of the finish, and improving the one-time forming qualification rate of the corner cut.

[0026] This invention utilizes a single-thread screw transmission structure in the cutting distance adjustment component to drive the cutting saw to make linear displacement along the direction perpendicular to the wall panel, achieving stepless and precise adjustment of the cutting depth, perfectly adapting to the thickness requirements of various specifications of prefabricated interior panels.

[0027] This invention uses two laser sights, one in front and one behind, that are coplanar with the rotation plane of the cutting saw blade. These sights can project a laser line corresponding to the actual cutting trajectory, enabling visual pre-alignment and facilitating rapid cutting line calibration. At the same time, the device is rigidly clamped and fixed to the wall panel by the positioning component, eliminating the need for manual hand-held operation and completely avoiding the problems of hand tremors and deviation during hand-held cutting.

[0028] This invention utilizes a double-threaded screw dual-drive structure in the spacing adjustment component to synchronously adjust the spacing between two sets of moving cutting devices. This adapts to the processing requirements of rectangular grooves and parallel slits of different widths, eliminating the need for repeated positioning and multiple cuts. Double-slit synchronous cutting can be completed in a single operation, improving the processing efficiency of grooves. With synchronous control from the control terminal, the two sets of cutting saws can be started, stopped, and fed synchronously, ensuring that the cutting depth, feed speed, and parallelism of the two slits are completely consistent. This avoids defects such as groove distortion, uneven width, and misaligned cuts caused by traditional multiple cuts, significantly improving the quality of groove forming.

[0047] 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.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0049] For an example, please refer to... Figures 1 to 5 As shown:

[0050] To address the problems mentioned in the technical solutions, this application provides a mobile cutting device for prefabricated interior panels used in construction, including a mobile cutting device comprising: a mounting base 1; a positioning component 2, which is mounted on the mounting base 1 and used to clamp and fix the entire device to the wall panel; an angle adjustment support frame 3, which is fixedly installed in the middle of the mounting base 1, and an electric slide rail 4 is rotatably connected to the angle adjustment support frame 3, which is used to drive the cutting saw 5 to move and cut along both sides of the wall panel thickness direction; and an angle adjustment component 6, which is mounted on the mounting base 1. It also includes an angle adjustment component 6, which is used to adjust the position of the electric slide rail 4 on the angle adjustment support frame 3, thereby adjusting the cutting angle of the cutting saw 5; a handheld frame 7, on which a control terminal 8 is fixedly installed, which is electrically connected to the electric slide rail 4 and the cutting saw 5 respectively, and the control terminal 8 controls the start and stop of the electric slide rail 4 and the cutting saw 5, and can also control and set the movement trajectory of the electric slide rail 4 driving the cutting saw 5; and a cutting distance adjustment component 9, which is set between the electric slide rail 4 and the cutting saw 5, for adjusting the cutting depth of the cutting saw 5 cutting the wall panel.

[0051] Among them, the cutting saw 5 can be connected to an existing dust removal structure to reduce the impact of dust on the construction environment and related structures in the equipment.

[0052] Preferably, both the angle adjustment support frame 3 and the electric slide rail 4 are U-shaped, and the angle adjustment support frame 3 and the electric slide rail 4 are rotated at their ends.

[0053] Specifically, the U-shaped electric slide rail 4 can be fully connected to both sides of the wall panel in the thickness direction, driving the cutting saw 5 to achieve full-thickness through-cutting from one side of the wall panel to the other, breaking through the cutting depth limitation of traditional handheld circular saws.

[0054] Preferably, the positioning component 2 includes a guide frame 21 fixed on the mounting base 1 and a double-threaded screw 22 rotating on the mounting base 1. The double-threaded screw 22 can drive two movable seats 23 to move towards or away from each other along the guide frame 21. An adjustment knob 24 is fixedly provided at the end of the double-threaded screw 22. A support rod 25 is fixedly connected to each of the two movable seats 23. A centering rod 26 is fixedly connected to the end of the support rod 25 away from the movable seat 23. The centering rod 26 passes through the center of the rotating end of the angle adjustment support frame 3 and the electric slide rail 4, so that the clamping reference of the equipment is completely coincident with the angle rotation reference. Structurally, it ensures that the cutting trajectory and the preset cutting line will not deviate from the reference during the angle adjustment process, thus ensuring cutting accuracy. A clamping plate 27 is fixedly connected to the end of the centering rod 26 away from the support rod 25.

[0055] Specifically, when the adjustment knob 24 is turned clockwise, causing the double-threaded screw 22 to rotate, the two moving seats 23 will move synchronously towards each other along the guide frame 21. This, in turn, will cause the two sets of clamping plates 27 to clamp synchronously on both sides of the wall panel through the support rod 25 and the centering rod 26, thus achieving rigid fixation of the equipment. When the adjustment knob 24 is turned counterclockwise, the two sets of clamping plates 27 will move synchronously away from each other, releasing the wall panel. The guide frame 21 radially limits the movement of the moving seats 23, ensuring that they can only move in a straight line. There is no deflection or jamming during the clamping process, ensuring that the clamping force of the two sets of clamping plates 27 is evenly distributed. The maximum clamping force of a single set can reach 500N. During operation, the equipment does not shift or shake.

[0056] Preferably, the clamping plate 27 includes a suspension rod 271 and an arc clamping plate 272. The centering rod 26 is fixedly connected to the arc clamping plate 272 through the suspension rod 271. A hollow area can be formed between the suspension rod 271 and the arc clamping plate 272 to ensure that the cutting saw 5 cuts to the root of the inside corner to the maximum extent.

[0057] Specifically, the clamping surface of the arc clamping plate 272 is vulcanized with a nitrile rubber anti-slip pad, which can increase the friction with the wall panel surface and prevent scratches on the wall panel finish and damage to the substrate during clamping. The suspension rod 271 adopts an L-shaped cantilever structure. At the same time, the hollow area formed between the suspension rod 271 and the arc clamping plate 272 can completely avoid the feed path of the cutting saw 5 without any structural interference, ensuring that the cutting saw 5 can feed to the extreme position at the root of the inside corner, minimizing the cutting residue area and laying the foundation for the subsequent corner block breakage component 10 operation.

[0058] Preferably, the angle adjustment assembly 6 includes a rod sleeve seat 61 rotatably mounted on the mounting base 1, a multi-stage telescopic member 62 is fixedly provided inside the rod sleeve seat 61, a connecting rod 63 is fixedly connected to the inner side of the electric slide rail 4, and the telescopic end of the multi-stage telescopic member 62 is rotatably connected to the connecting rod 63.

[0059] Among them, the multi-stage telescopic component 62 adopts the existing three-stage or higher manual telescopic structure. Through the extension and retraction of the multi-stage telescopic component 62, the cutting angle of the electric slide rail 4 can be precisely adjusted. Both the fixed end and the telescopic end of the multi-stage telescopic component 62 adopt a fish-eye bearing hinge structure, which can adapt to the angle change during the rotation of the electric slide rail 4, ensuring smooth transmission without jamming. After the angle adjustment is completed, the position can be automatically locked, and no angle deviation will occur during operation, ensuring the long-term stability of the cutting angle.

[0060] Preferably, the cutting distance adjustment assembly 9 includes an adjustment seat 91 fixed on the moving frame of the electric slide rail 4. A single threaded screw 92 is rotatably installed inside the adjustment seat 91. A knob 93 is fixedly connected to one end of the single threaded screw 92. The single threaded screw 92 can drive the moving seat 94 to slide linearly along the inner side of the adjustment seat 91. The moving seat 94 is fixedly connected to the cutting saw 5.

[0061] Specifically, the inner side of the adjusting seat 91 is equipped with a high-precision linear guide rail that is compatible with the moving seat 94, which limits the movement of the moving seat 94 and ensures that it can only move linearly in a direction perpendicular to the wall panel surface. When the knob 93 is turned to drive the single threaded screw 92 to rotate, the moving seat 94 can be driven to move linearly along the guide rail, thereby driving the cutting saw 5 to move closer to or away from the wall panel, so as to achieve precise adjustment of the cutting depth. The surface of the adjusting seat 91 can be set with depth scale lines, with a minimum scale value of 0.05mm, so that the cutting depth value can be read directly. It is compatible with various specifications of prefabricated interior panels, ensuring that double-sided cutting can completely cut through the wall panel. The moving seat 94 and the cutting saw 5 are rigidly connected by 4 hexagonal bolts to ensure that the rotation plane of the saw blade of the cutting saw 5 is completely perpendicular to the feed direction, so as to avoid saw blade wobble and skewed cut during the cutting process.

[0062] For further embodiments, please refer to Figure 5 As shown:

[0063] Laser sights 12 are fixedly installed inside the end of the centering rod 26 away from the support rod 25 and on the electric slide rail 4. The two laser sights 12 and the saw blade of the cutting saw 5 are on the same plane. The two laser sights 12 can facilitate the pre-alignment of the cutting trajectory of the cutting saw 5.

[0064] Specifically, both laser sights 12 use Class II safety-grade linear green lasers with a rated power of ≤5mW, meeting national power tool safety standards and maintaining clear visibility even in bright sunlight conditions. The two laser sights 12 are positioned one in front of the other, with their emission planes completely coplanar with the rotary cutting plane of the cutting saw 5. After the equipment is started, the two laser sights 12 illuminate synchronously, projecting a complete linear laser line that coincides with the actual cutting trajectory. Workers do not need to bend over to observe the saw blade edge; they can quickly and accurately align the laser line by visually observing the overlap between the laser line and the preset cutting reference line on the wall panel. Furthermore, one of the laser sights 12 can quickly align with the corner of an inside corner. Simultaneously, the laser sights 12 are linked with the control terminal 8; the laser illuminates synchronously when the cutting saw 5 spindle starts and turns off after a 3-second delay when the spindle stops, eliminating the need for manual switching and making operation convenient.

[0065] Preferably, a pointer 13 is fixedly installed on the electric slide rail 4, and a circumferential scale line 14 is provided at the end of the angle adjustment support frame 3, and the center of the circumferential scale line 14 corresponds to the rotation center between the angle adjustment support frame 3 and the electric slide rail 4.

[0066] Specifically, when adjusting the cutting angle, the staff can extend and retract the multi-stage telescopic component 62 to drive the electric slide rail 4 to rotate. At the same time, they can observe the value indicated by the pointer 13 on the circumferential scale line 14 to accurately adjust and lock the required cutting angle without the need for repeated measurement and calibration using an angle ruler. Meanwhile, the circumferential scale line 14 is marked with positioning scale lines for commonly used angles, including 30°, 45°, 60°, and 90°, which can achieve quick coarse adjustment and improve the efficiency of angle adjustment.

[0067] For further embodiments, please refer to Figure 7 As shown:

[0068] An electric slide rail 4 is equipped with a corner block breaking assembly 10. The corner block breaking assembly 10 includes a connecting frame 101 fixed in the middle of the electric slide rail 4. A limit frame 102 is slidably installed on the connecting frame 101 along the straight cutting direction of the cutting saw 5. A single threaded screw 103 is rotatably installed on the limit frame 102. A knob 104 is fixedly connected to one end of the single threaded screw 103. A breaking support block 105 is fixedly installed on the side of the limit frame 102 facing the cutting saw 5. The breaking support block 105 has a right-angle structure, and the inclined surface of the breaking support block 105 faces the corner wall block to be cut. The single threaded screw 103 is threadedly connected to the connecting frame 101, which can drive the breaking support block 105 to insert into the cutting gap and squeeze the corner wall block, causing it to break and separate from the wall panel.

[0069] Specifically, after cutting the two intersecting cutting lines of the L-shaped inside corner, the worker rotates knob 3 104 clockwise, causing the fracture support block 105 to be inserted into the cutting gap at the inside corner at a uniform speed. The inclined surface of the fracture support block 105 continuously applies pressure to the inside corner wall block, causing stress concentration along the cutting line in the tiny residual connection area at the root of the inside corner, thus resulting in complete fracture. The inside corner wall block can be removed relatively intact without manual chiseling or prying. At the same time, the feed stroke of the fracture support block 105 can be precisely adjusted through the single threaded screw 2 103 to adapt to inside corner cutting gaps of different thicknesses and depths, making it highly versatile. After the operation is completed, rotating knob 3 104 counterclockwise will cause the fracture support block 105 to return to its initial position without affecting subsequent cutting operations.

[0070] For further embodiments, please refer to Figure 8 As shown:

[0071] It also includes a spacing adjustment component 11. There are two sets of moving cutting devices. The spacing adjustment component 11 can adjust the distance between the two sets of moving cutting devices to meet the processing of grooves with different spacing. The spacing adjustment component 11 includes a mounting base 2 111. The handheld frame 7 is fixed in the middle of the mounting base 2 111. A guide frame 2 112 is fixedly installed on the mounting base 2 111. A double threaded screw 2 113 is also rotatably installed on the mounting base 2 111. A knob 4 114 is fixedly installed at the end of the double threaded screw 2 113. The double threaded screw 2 113 can drive two moving seats 3 115 to move towards or away from each other along the guide frame 2 112. The two moving seats 3 115 are fixedly connected to two mounting bases 111 respectively. The guide frame 2 112 is provided with a distance scale line 116 to facilitate direct reading of the spacing between the two cutting saws 5.

[0072] Specifically, when the knob 114 is turned to rotate the double-threaded screw 113, the two moving seats 115 move synchronously towards or away from each other along the double parallel optical axes of the guide frame 112, thereby driving the two sets of moving cutting devices to open and close synchronously, and precisely adjusting the distance between the two cutting saws 5. The minimum scale value of the distance scale line 116 is 0.1mm, which can directly read the distance value between the two cutting saws 5 without the need for additional measurement with a tape measure. It can quickly adapt to the processing needs of rectangular grooves and parallel cuts of different widths, without repeated positioning and multiple cuts. The double cut can be completed in one operation, which greatly improves the efficiency of batch groove processing. The handheld frame 7 is fixed in the middle of the mounting base 111, providing a unified gripping fulcrum for the two sets of cutting devices. At the same time, the control terminal 8 can synchronously control the cutting saws 5 and electric slide rails 4 of the two sets of moving cutting devices to achieve synchronous start and stop and synchronous feed of the two sets, ensuring that the cutting depth, feed speed and cut quality of the two cuts are completely consistent.

[0073] Complete working principle and usage process of this invention

[0074] Pre-treatment of panels: Use an ink fountain to mark the preset cutting baseline on the surface of the prefabricated interior panel. If it is a cut at an inside corner, mark two intersecting L-shaped cutting lines; if it is a cut at a groove, mark two parallel cutting lines; if it is a cut at a bevel, mark the cutting angle.

[0075] Cutting depth adjustment: According to the thickness of the wall panel to be cut, rotate the knob 93 of the cutting distance adjustment component 9 to drive the cutting saw 5 to move, and adjust the cutting depth through the depth scale line on the adjustment seat 91;

[0076] Cutting angle adjustment: The multi-stage telescopic component 62 of the angle adjustment component 6 extends and retracts, driving the electric slide rail 4 to rotate, and the target cutting angle is locked by the pointer 13 and the circumferential scale line 14;

[0077] Dual-set spacing adjustment groove cutting scenario: If a rectangular groove needs to be processed, rotate the knob 114 of the spacing adjustment component 11 to drive the two sets of moving cutting devices to open and close synchronously. Lock the spacing between the two cutting saws 5 through the distance scale line 116 so that it is completely consistent with the width of the groove.

[0078] Cutting parameter presets: In the control terminal 8, the spindle speed of the cutting saw 5 and the feed speed of the electric slide rail 4 are preset according to the type of wall panel substrate. For gypsum / calcium silicate board, the recommended spindle speed is 3000-4000 r / min and the feed speed is 1-2 m / min. For wood-plastic / wood substrate, the recommended spindle speed is 4000-6000 r / min and the feed speed is 2-3 m / min. For thicker plates and hard materials, the feed speed can be appropriately reduced.

[0079] Equipment clamping and positioning: The entire equipment is attached to the surface of the wall panel, so that the feed direction of the cutting saw 5 is parallel to the preset cutting baseline. Rotate the adjustment knob 24 of the positioning component 2 to drive the double threaded screw 22 to rotate, and drive the two sets of clamping plates 27 to clamp the two sides of the wall panel simultaneously, thus completing the rigid fixation of the equipment.

[0080] Precise alignment of the cutting trajectory: By controlling the terminal 8 to light up two laser sights 12, one in front of the other, a straight laser line is projected that coincides with the actual cutting trajectory. The clamping position of the equipment is finely adjusted so that the two laser lines completely coincide with the preset cutting reference line on the wall panel, thus completing the pre-alignment of the cutting trajectory. After alignment, the adjustment knob 24 of the positioning component 2 is locked to ensure that the equipment does not shift during operation.

[0081] Automated interlocking cutting operation: The cutting program is started via control terminal 8, and the system executes preset standardized timing interlocking control:

[0082] First, start the spindle motor of the cutting saw 5 to drive the saw blade to rotate at high speed. The control terminal 8 monitors the spindle speed in real time. Only when the spindle reaches the preset rated speed and runs stably will it send a feed command to the electric slide rail 4.

[0083] When the electric slide rail 4 is started, it drives the cutting saw 5 to feed at a constant speed in a straight line along the preset trajectory, completing the full thickness through-cut of the wall panel; during the cutting process, the two laser sights 12 continuously project the cutting trajectory, and the staff can observe the cutting status in real time. If an emergency occurs, the emergency stop button of the control terminal 8 can be pressed, and the system will instantly cut off all power and lock the equipment status.

[0084] When the electric slide rail 4 drives the cutting saw 5 to the preset cutting endpoint, the system first controls the electric slide rail 4 to stop feeding, and then delays for 2 seconds to shut down the spindle motor of the cutting saw 5 to complete the single-pass cutting operation; if it is a double-set groove cutting, the control terminal 8 synchronously controls the two sets of moving cutting devices to complete synchronous cutting, and two parallel cuts can be formed in one operation.

[0085] Corner block breakage and separation, corner cutting scene

[0086] After cutting the two intersecting cutting lines of the L-shaped inside corner, rotate knob three 104 of the corner block fracture component 10 to drive the fracture support block 105 to be inserted into the cutting gap at the inside corner at a uniform speed. The inclined surface of the fracture support block 105 continuously applies directional extrusion force to the inside corner wall block, so that the remaining connecting area at the root of the inside corner is completely broken along the cutting line. The inside corner wall block can be completely removed without manual chiseling or prying, thus completing the inside corner cutting operation. After the operation is completed, rotate knob three 104 in the opposite direction to drive the fracture support block 105 back to the initial position.

[0087] Completed work and reset equipment: After all cutting operations are completed, rotate the adjustment knob 24 of the positioning component 2 in the reverse direction to release the clamping plate 27 and remove the equipment from the wall panel; control the electric slide rail 4 through the control terminal 8 to drive the cutting saw 5 back to the origin, rotate each adjustment knob in the reverse direction to reset the equipment to the initial state, clean the dust on the saw blade, laser sight lens and equipment surface, and complete the entire process.
