Description

Technical Field

[0001] This invention relates to the field of deburring devices, specifically a deburring device for die-cast parts with surface flaw detection function. Background Technology

[0002] Die casting is a metal casting process characterized by applying high pressure to molten metal using the cavity of a mold. The mold is usually made of a higher strength alloy. This process is somewhat similar to injection molding. Most die castings do not contain iron, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. However, burrs on the surface of the die casting mold can affect the molding quality of the product.

[0003] Existing deburring equipment for die-cast parts may result in poor deburring effect due to the influence of the grinding force of the grinding device. In addition, the grinding process will generate a large amount of flying metal or other dust, causing pollution. Summary of the Invention

[0004] The purpose of this invention is to provide a deburring device for die-cast parts with surface flaw detection function, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A deburring device for die-cast parts with surface flaw detection function includes: a machine body with a cabinet door on its surface; a fixing device inside the machine body, the fixing device including: a hydraulic cylinder, the hydraulic cylinder being disposed on the top of the machine body, a rotating plate being rotatably mounted on the hydraulic rod in the hydraulic cylinder; a rotating platform being disposed at the bottom of the machine body, a support being disposed at the bottom of the rotating platform, the support being connected to the machine body; a motor being disposed within the support, the drive shaft of the motor passing through the support and connecting to the rotating platform; the rotating platform being rotatably connected to the machine body; a cooling plate being disposed within the rotating platform; and a grinding device being disposed inside the machine body, the grinding device being slidably connected to the machine body.

[0007] The worker opens the cabinet door and places the workpiece to be deburred on the rotating table. Then, the controller activates the hydraulic cylinder, causing the hydraulic rod to move closer to the rotating table. During this movement, the hydraulic rod drives the rotating plate, bringing it into contact with the upper surface of the workpiece. The interaction between the rotating plate and the rotating table fixes the workpiece in place. Next, the controller activates the cooling element inside the rotating table, transferring the low temperature to the rotating table and then to the workpiece. The burrs on the workpiece surface become brittle under the influence of the low temperature. The controller then activates the grinding device, which moves closer to the workpiece. Once the grinding device contacts the workpiece surface, the controller activates the motor inside the support, causing the drive shaft to rotate the rotating table. During this rotation, the rotating table rotates the workpiece, and the grinding device deburrs the sidewalls of the workpiece. Due to the low temperature, the burrs are easily removed during grinding, improving the efficiency and quality of deburring, resulting in a smooth and clean workpiece surface.

[0008] Preferably, the grinding device includes: a placement cavity, which is symmetrically arranged on both sides of the machine body, a high-pressure air pump is installed in the placement cavity to draw in outside air, a sliding groove is provided on the side wall of the placement cavity, a sliding block is provided in the sliding groove, a micro motor is provided in the sliding block, a pulley is provided on one side of the sliding block located in the sliding groove, and the drive shaft of the micro motor is connected to the pulley.

[0009] Preferably, the sliding block is provided with a channel, a grinding plate is provided on the side of the sliding block away from the placement cavity, a pipe is provided on the side of the sliding block away from the grinding plate, the end of the pipe away from the sliding block is connected to a high-pressure air pump, a plurality of air passages are provided in the grinding plate, a plurality of grinding components are provided in the air passages, and the grinding components provided in two adjacent air passages are arranged alternately.

[0010] Preferably, the grinding assembly includes: a vibrating tube disposed within an air passage, one end of the vibrating tube passing through a grinding plate, the other end of the vibrating tube suspended in the air passage, a vibrating rod disposed within the vibrating tube, one end of the vibrating rod extending out of the vibrating tube, and a grinding disc disposed on the side of the vibrating rod away from the vibrating tube.

[0011] Preferably, a swing rod is provided on one side of the vibrating tube, the vibrating tube and the swing rod are flexible, the swing rod and the vibrating tube are on the same vertical plane, and a brush is provided at one end of the swing rod through the grinding plate.

[0012] Preferably, a flow guide group is provided on the side of the swing rod away from the vibrating tube. The flow guide group consists of a lower flow guide and an upper flow guide. The upper flow guide is located on the side of the lower flow guide away from the swing rod. The lower flow guide is set at an obtuse angle with the horizontal plane, the upper flow guide is set at an acute angle with the horizontal plane, and the included angle between the lower flow guide and the upper flow guide is set at an obtuse angle.

[0013] Preferably, the grinding plate has an air outlet on the side away from the sliding block, the air outlet is connected to an air passage, the air passage is connected to a channel inside the sliding block, a dust collection chamber is provided between the two placement chambers, and a dust outlet is provided at the bottom of the dust collection chamber.

[0014] After the workpiece is placed on the rotating table surface, the controller starts the micro motor in the sliding block. The drive shaft in the micro motor drives the pulley to rotate, and the pulley drives the sliding block to move. The sliding block moves along the slide groove to the side closer to the workpiece. During the movement of the sliding block, the sliding block drives the grinding plate to move. During the movement of the grinding plate, the grinding plate drives the grinding assembly to move, so that the grinding assembly comes into contact with the surface of the workpiece.

[0015] When the grinding assembly comes into contact with the surface of the workpiece, the controller starts the high-pressure air pump. The high-pressure air pump draws in outside air, which is then pressurized and transmitted through a pipe to the channel in the sliding block. The air then enters the air passage through the channel in the sliding block. After entering the air passage, the high-pressure gas flows from the bottom of the grinding plate towards the side near the air outlet. During the flow of the high-pressure gas, it encounters the vibrating tube. Since the vibrating tube is suspended at one end of the air passage, the high-pressure gas blows onto the vibrating tube, causing it to vibrate. The vibration is then transmitted through the vibrating tube to the vibrating rod, which vibrates in response to the vibration. The vibration is transmitted to the surface of the grinding disc, and the grinding disc grinds the burrs on the surface of the workpiece under the action of the vibration.

[0016] When high-pressure gas flows through the vibrating tube, a vortex effect is generated between the vibrating tube and the swing rod, resulting in turbulence. After the turbulence flows through the swing rod, the swing rod swings irregularly under the influence of the turbulence. During the swinging process, the swing rod drives the brush to swing. When the brush swings, it cleans the burrs and debris remaining on the surface of the workpiece, avoiding the burrs and debris remaining on the surface of the workpiece, which would cause scratches on the surface of the workpiece, thus improving the quality of deburring the workpiece.

[0017] After the high-pressure gas in turbulence flows through the swing arm, it encounters the lower guide flow. The high-pressure gas changes from turbulence to oblique airflow through the lower guide flow, and then flows to the upper guide flow through the lower guide flow. Under the action of the upper guide flow, the oblique airflow changes from oblique airflow to vertical airflow, which rectifies the high-pressure gas. After rectification, the high-pressure gas moves to the next grinding assembly.

[0018] After the high-pressure gas flows to the air outlet, it is immediately discharged through the air outlet. The high-pressure gas blows towards the surface of the workpiece. As the high-pressure gas flows over the surface of the workpiece, it blows off the burrs and debris remaining on the surface of the workpiece. The burrs and debris are blown towards the side closer to the dust collection chamber by the high-pressure airflow. Then the burrs and debris enter the dust collection chamber and enter the ash outlet through the dust collection chamber, and are discharged through the ash outlet.

[0019] As the workpiece rotates under the action of the rotary table, it comes into contact with the grinding components when it rotates. The grinding components grind and remove the burrs on the surface of the workpiece. Since the grinding components in the two adjacent air passages are arranged in an alternating manner, after the grinding disc grinds the burrs, the brush immediately cleans up the debris that has been ground off.

[0020] High-pressure gas flows in the air passage. When the high-pressure gas encounters the vibrating tube, the vibrating tube vibrates under the action of the high-pressure gas. Subsequently, the high-pressure gas generates a vortex street effect under the influence of the vibrating tube. The swing rod is driven by the vortex street effect, which then causes the grinding disc to grind the burrs. Since the vibration of the vibrating tube is transmitted to the grinding disc, the efficiency of the grinding disc in grinding burrs is improved, and the quality of deburring the workpiece surface is improved.

[0021] By using high-pressure gas to drive the vibrating tube to vibrate and the swing rod to swing, energy consumption is reduced. At the same time, the high-pressure gas blowing and the brush work together to remove burrs and debris from the surface of the workpiece, which improves the quality and efficiency of burr and debris removal.

[0022] Preferably, the machine body is further provided with an ultrasonic testing device, which is located between two grinding plates. A push cylinder is provided on the side of the ultrasonic testing device away from the cabinet door, and the push rod in the push cylinder is connected to the ultrasonic testing device.

[0023] After the burrs on the workpiece surface are removed, the controller controls the grinding device to reset, and the two grinding plates move away from the workpiece. Then, the controller controls the push cylinder to start, and the push rod in the push cylinder drives the ultrasonic detection device to move. The ultrasonic detection device moves closer to the workpiece, and then the controller controls the ultrasonic detection device to start. The ultrasonic detection device emits sound waves towards the workpiece. The sound waves are reflected after encountering the workpiece. After receiving the rebound sound waves, the ultrasonic detection device converts the sound wave signal into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. If the signal is not affected or only slightly affected, it indicates that the workpiece surface is smooth and flat. If the signal shows a large fluctuation, there are still burrs on the workpiece surface. The grinding device then grinds the workpiece again under the action of the controller, improving the quality of deburring and making the workpiece surface smooth and clean.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0025] 1. High-pressure gas flows in the air passage. When the high-pressure gas encounters the vibrating tube, the vibrating tube vibrates under the action of the high-pressure gas. Subsequently, the high-pressure gas generates a vortex street effect under the influence of the vibrating tube. The swing rod is driven by the vortex street effect, which in turn causes the grinding disc to grind the burrs. Since the vibration of the vibrating tube is transmitted to the grinding disc, the efficiency of the grinding disc in grinding burrs is improved, and the quality of deburring the workpiece surface is improved.

[0026] 2. High-pressure gas is used to drive the vibrating tube to vibrate and the swing rod to swing, which reduces energy consumption. At the same time, the high-pressure gas blowing and brush work together to remove burrs and debris from the surface of the workpiece, which improves the quality and efficiency of burr and debris removal.

[0038] 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.

[0039] Please see Figures 1-7 The present invention provides the following technical solution:

[0040] A deburring device for die-cast parts with surface flaw detection function includes: a body 1, the surface of which is provided with a cabinet door; a fixing device 2 is provided inside the body 1; the fixing device 2 includes: a hydraulic cylinder 21, which is located on the top of the body 1; a rotating plate 22 is rotatably mounted on the hydraulic rod of the hydraulic cylinder 21; a rotating platform 23 is provided at the bottom of the body 1; a support 24 is provided at the bottom of the rotating platform 23; the support 24 is connected to the body 1; a motor is provided inside the support 24; the drive shaft of the motor passes through the support 24 and connects to the rotating platform 23; the rotating platform 23 is rotatably connected to the body 1; a cooling plate is provided inside the rotating platform 23; and a grinding device 3 is also provided inside the body 1, which is slidably connected to the body 1.

[0041] The operator opens the cabinet door and places the workpiece to be deburred on the surface of the rotating table 23. Then, the controller starts the hydraulic cylinder 21, and the hydraulic rod in the hydraulic cylinder 21 moves towards the side closer to the rotating table 23. During the movement of the hydraulic rod, the hydraulic rod drives the rotating plate 22 to move, so that the rotating plate 22 contacts the upper surface of the workpiece. The interaction between the rotating plate 22 and the rotating table 23 fixes the workpiece. Then, the controller starts the cooling plate inside the rotating table 23. The low temperature generated by the cooling plate is transferred to the rotating table 23, and then to the workpiece. The burrs on the surface of the workpiece become brittle under the action of the low temperature. Then, the controller starts the grinding device 3, and the grinding device 3 moves towards the side closer to the workpiece. When the grinding device 3 contacts the surface of the workpiece, the controller starts the motor in the bracket 24. The drive shaft in the motor drives the rotating table 23 to rotate. During the rotation of the rotating table 23, the rotating table 23 drives the workpiece to rotate. The grinding device 3 then performs deburring treatment on the side wall of the workpiece. Due to the effect of the low temperature, the burrs can be easily removed when the grinding device 3 grinds them.

[0042] In one specific embodiment of the present invention, the grinding device 3 includes: a placement cavity 31, which is symmetrically arranged on both sides of the machine body 1. A high-pressure air pump is installed in the placement cavity 31 to draw in outside air. A sliding groove 32 is provided on the side wall of the placement cavity 31. A sliding block 33 is provided in the sliding groove 32. A micro motor is installed in the sliding block 33. A pulley is provided on one side of the sliding block 33 located in the sliding groove 32. The drive shaft of the micro motor is connected to the pulley.

[0043] In one specific embodiment of the present invention, a channel is provided inside the sliding block 33, a grinding plate 34 is provided on the side of the sliding block 33 away from the placement cavity 31, a pipe is provided on the side of the sliding block 33 away from the grinding plate 34, and a high-pressure air pump is connected to the end of the pipe away from the sliding block 33. A plurality of air passages 35 are provided inside the grinding plate 34, and a plurality of grinding components 36 are provided inside the air passages 35. The grinding components 36 provided in two adjacent air passages 35 are arranged alternately.

[0044] In one specific embodiment of the present invention, the grinding assembly 36 includes: a vibration tube 361, which is disposed in an air passage 35. One end of the vibration tube 361 passes through the grinding plate 34, and the other end of the vibration tube 361 is suspended in the air passage 35. A vibration rod 362 is disposed inside the vibration tube 361, with one end of the vibration rod 362 extending out of the vibration tube 361. A grinding disc 363 is disposed on the side of the vibration rod 362 away from the vibration tube 361.

[0045] In one specific embodiment of the present invention, a swing rod 364 is provided on one side of the vibration tube 361. The vibration tube 361 and the swing rod 364 are flexible. The swing rod 364 and the vibration tube 361 are on the same vertical plane. One end of the swing rod 364 passes through the grinding plate 34 and is provided with a brush 365.

[0046] In one specific embodiment of the present invention, a flow guide group 366 is provided on the side of the swing rod 364 away from the vibration tube 361. The flow guide group 366 consists of a lower flow guide 367 and an upper flow guide 368. The upper flow guide 368 is located on the side of the lower flow guide 367 away from the swing rod 364. The lower flow guide 368 is set at an obtuse angle with the horizontal plane, the upper flow guide 367 is set at an acute angle with the horizontal plane, and the included angle between the lower flow guide 367 and the upper flow guide 368 is set at an obtuse angle.

[0047] As a specific embodiment of the present invention, the grinding plate 34 is provided with an air outlet 37 on the side away from the sliding block 33. The air outlet 37 is connected to the air passage 35, the air passage 35 is connected to the channel inside the sliding block 33, and a dust collection chamber 38 is provided between the two placement chambers 31. A dust outlet 381 is provided at the bottom of the dust collection chamber 38.

[0048] When the workpiece is placed on the surface of the rotating table 23, the controller controls the micro motor in the sliding block 33 to start. The drive shaft in the micro motor drives the pulley to rotate, and the pulley drives the sliding block 33 to move. The sliding block 33 moves along the slide groove 32 to the side closer to the workpiece. During the movement of the sliding block 33, the sliding block 33 drives the grinding plate 34 to move. During the movement of the grinding plate 34, the grinding plate 34 drives the grinding assembly 36 to move, so that the grinding assembly 36 contacts the surface of the workpiece.

[0049] When the grinding assembly 36 comes into contact with the surface of the workpiece, the controller controls the high-pressure air pump to start. The high-pressure air pump draws in outside air, which is then pressurized and transmitted through a pipe to the channel in the sliding block 33. Subsequently, it enters the air passage 35 through the channel in the sliding block 33. After the high-pressure gas enters the air passage 35, it flows from the bottom end of the grinding plate 34 towards the side near the air outlet 37. During the flow of the high-pressure gas, the high-pressure gas encounters the vibrating tube 361. Since the vibrating tube 361 is located at one end of the air passage 35 and is suspended, the high-pressure gas blows onto the vibrating tube 361, causing the vibrating tube 361 to vibrate. The vibration is then transmitted through the vibrating tube 361 to the vibrating rod 362. The vibrating rod 362 vibrates after being affected by the vibration. The vibration is transmitted to the surface of the grinding disc 363, and the grinding disc 363 grinds the burrs on the surface of the workpiece under the action of the vibration.

[0050] When the high-pressure gas flows through the vibrating tube 361, a vortex effect is generated between the vibrating tube 361 and the swing rod 364, which causes the high-pressure gas to turbulent. After the turbulent flow passes through the swing rod 364, the swing rod 364 swings irregularly under the influence of the turbulence. During the swinging process, the swing rod 364 drives the brush 365 to swing. When the brush 365 swings, it cleans the burrs and debris remaining on the surface of the workpiece, so as to avoid burrs and debris remaining on the surface of the workpiece, which would cause scratches on the surface of the workpiece.

[0051] After the high-pressure gas in turbulence flows through the swing rod 364, it encounters the lower guide 367. The high-pressure gas changes from turbulence to oblique airflow through the lower guide 367, and then flows to the upper guide 368 through the lower guide 367. Under the action of the upper guide 368, the oblique airflow changes from oblique airflow to vertical airflow, which rectifyes the high-pressure gas. After rectification, the high-pressure gas moves to the next grinding assembly 36.

[0052] After the high-pressure gas flows to the air outlet 37, it is immediately discharged through the air outlet 37. The high-pressure gas blows towards the surface of the workpiece. The high-pressure gas flows over the surface of the workpiece and blows off the burrs and debris remaining on the surface of the workpiece. The burrs and debris are blown towards the side close to the dust collection chamber 38 by the high-pressure airflow. Then the burrs and debris enter the dust collection chamber 38 and enter the ash outlet 381 through the dust collection chamber 38, and are discharged through the ash outlet 381.

[0053] As the workpiece rotates under the action of the rotating table 23, it comes into contact with the grinding assembly 36 when it rotates. The grinding assembly 36 grinds and removes the burrs on the surface of the workpiece. Since the grinding assemblies 36 arranged in the adjacent two air passages 35 are staggered, after the grinding disc 363 grinds the burrs, the brush 365 cleans up the grinding debris.

[0054] As a specific embodiment of the present invention, an ultrasonic testing device is also provided inside the body 1. The ultrasonic testing device is located between two grinding plates 34. A push cylinder is provided on the side of the ultrasonic testing device away from the cabinet door, and the push rod in the push cylinder is connected to the ultrasonic testing device.

[0055] After the burrs on the workpiece surface are removed, the controller controls the grinding device 3 to reset, and the two grinding plates 34 move away from the workpiece. Then, the controller controls the push cylinder to start, and the push rod in the push cylinder drives the ultrasonic detection device to move. The ultrasonic detection device moves closer to the workpiece, and then the controller controls the ultrasonic detection device to start. The ultrasonic detection device emits sound waves towards the workpiece. The sound waves are reflected after encountering the workpiece. After receiving the rebound sound waves, the ultrasonic detection device converts the sound wave signal into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. If the signal is not affected or only slightly affected, it indicates that the workpiece surface is smooth and flat. If the signal shows a large fluctuation, there are still burrs on the workpiece surface. The grinding device 3 then grinds the workpiece again under the action of the controller, making the workpiece surface smooth and clean.

[0056] Working principle of the invention:

[0057] The operator opens the cabinet door and places the workpiece to be deburred on the surface of the rotating table 23. Then, the controller starts the hydraulic cylinder 21, and the hydraulic rod in the hydraulic cylinder 21 moves to the side closer to the rotating table 23. During the movement of the hydraulic rod, the hydraulic rod drives the rotating plate 22 to move, so that the rotating plate 22 contacts the upper surface of the workpiece. The interaction between the rotating plate 22 and the rotating table 23 fixes the workpiece. Then, the controller starts the cooling plate in the rotating table 23. The low temperature generated by the cooling plate is transferred to the rotating table 23, and then to the workpiece through the rotating table 23. The burrs on the surface of the workpiece become brittle under the action of the low temperature. Then, the controller starts the grinding device 3, and the grinding device 3 moves to the side closer to the workpiece. When the grinding device 3 contacts the surface of the workpiece, the controller starts the motor in the bracket 24. The drive shaft in the motor drives the rotating table 23 to rotate. During the rotation of the rotating table 23, the rotating table 23 drives the workpiece to rotate, and the grinding device 3 then deburrs the side wall of the workpiece.

[0058] When the workpiece is placed on the surface of the rotating table 23, the controller controls the micro motor in the sliding block 33 to start. The drive shaft in the micro motor drives the pulley to rotate, and the pulley drives the sliding block 33 to move. The sliding block 33 moves along the slide groove 32 to the side closer to the workpiece. During the movement of the sliding block 33, the sliding block 33 drives the grinding plate 34 to move. During the movement of the grinding plate 34, the grinding plate 34 drives the grinding assembly 36 to move, so that the grinding assembly 36 contacts the surface of the workpiece.

[0059] When the grinding assembly 36 comes into contact with the surface of the workpiece, the controller controls the high-pressure air pump to start. The high-pressure air pump draws in outside air, which is then pressurized and transmitted through a pipe to the channel in the sliding block 33. Subsequently, it enters the air passage 35 through the channel in the sliding block 33. After the high-pressure gas enters the air passage 35, it flows from the bottom end of the grinding plate 34 towards the side near the air outlet 37. During the flow of the high-pressure gas, the high-pressure gas encounters the vibrating tube 361. Since the vibrating tube 361 is located at one end of the air passage 35 and is suspended, the high-pressure gas blows onto the vibrating tube 361, causing the vibrating tube 361 to vibrate. The vibration is then transmitted through the vibrating tube 361 to the vibrating rod 362. The vibrating rod 362 vibrates after being affected by the vibration. The vibration is transmitted to the surface of the grinding disc 363, and the grinding disc 363 grinds the burrs on the surface of the workpiece under the action of the vibration.

[0060] When the high-pressure gas flows through the vibrating tube 361, a vortex effect is generated between the vibrating tube 361 and the swing rod 364, which causes the high-pressure gas to turbulent. After the turbulent flow passes through the swing rod 364, the swing rod 364 swings irregularly under the influence of the turbulence. During the swinging process, the swing rod 364 drives the brush 365 to swing. When the brush 365 swings, it cleans the burrs and debris remaining on the surface of the workpiece, so as to avoid burrs and debris remaining on the surface of the workpiece, which would cause scratches on the surface of the workpiece.

[0061] After the high-pressure gas in turbulence flows through the swing rod 364, it encounters the lower guide 367. The high-pressure gas changes from turbulence to oblique airflow through the lower guide 367, and then flows to the upper guide 368 through the lower guide 367. Under the action of the upper guide 368, the oblique airflow changes from oblique airflow to vertical airflow, which rectifyes the high-pressure gas. After rectification, the high-pressure gas moves to the next grinding assembly 36.

[0062] After the high-pressure gas flows to the air outlet 37, it is immediately discharged through the air outlet 37. The high-pressure gas blows towards the surface of the workpiece. The high-pressure gas flows over the surface of the workpiece and blows off the burrs and debris remaining on the surface of the workpiece. The burrs and debris are blown towards the side close to the dust collection chamber 38 by the high-pressure airflow. Then the burrs and debris enter the dust collection chamber 38 and enter the ash outlet 381 through the dust collection chamber 38, and are discharged through the ash outlet 381.

[0063] As the workpiece rotates under the action of the rotating table 23, it comes into contact with the grinding assembly 36 when it rotates. The grinding assembly 36 grinds and removes the burrs on the surface of the workpiece. Since the grinding assemblies 36 arranged in the adjacent two air passages 35 are staggered, after the grinding disc 363 grinds the burrs, the brush 365 cleans up the debris that was ground off.

[0064] After the burrs on the workpiece surface are removed, the controller controls the grinding device 3 to reset, and the two grinding plates 34 move away from the workpiece. Then, the controller controls the push cylinder to start, and the push rod in the push cylinder drives the ultrasonic detection device to move. The ultrasonic detection device moves closer to the workpiece, and then the controller controls the ultrasonic detection device to start. The ultrasonic detection device emits sound waves towards the workpiece. The sound waves are reflected after encountering the workpiece. After receiving the rebound sound waves, the ultrasonic detection device converts the sound wave signal into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. If the signal is not affected or only slightly affected, it indicates that the workpiece surface is smooth and flat. If the signal shows a large fluctuation, there are still burrs on the workpiece surface. The grinding device 3 then grinds the workpiece again under the action of the controller, making the workpiece surface smooth and clean.
