[0068] Workpiece grinding diameter range: 90 to 150 mm.

[0069] Workpiece grinding thickness range: 2.6 to 4.0 mm.

[0070] In order to meet the working needs of the grinding wheel dressing unit 68, before dressing the grinding wheel, the right spindle box locking screw 56 should be loosened and removed, and then the right spindle box should be moved to the right by about 180mm by rotating the main handle 59 clockwise, so that the working space of the dresser is vacated between the left and right spindle boxes. When dressing the grinding wheel, the grinding wheel dressing hand wheel 72 is rotated, and the fixed seat 70 (dresser) moves back and forth, driving the diamond pen 75 to dress the grinding wheel. The allowance for each dressing of the grinding wheel is recommended to be 0.10mm, that is, the fine-tuning hand wheel is rotated two circles.

[0071] After the grinding wheel is dressed, take out the diamond pen 75 and use it to tilt the corners of the grinding wheel to facilitate the smooth entry into the grinding area when grinding the workpiece. Note that the diamond pen must be held firmly by hand to prevent the diamond pen from falling into the gap between the grinding wheel and the grinding wheel cover, causing damage to the grinding wheel.

[0072] An operation panel 76 is provided on the frame 1. A left grinding wheel adjustment unit 77 is provided in the left spindle box 7;

[0074] The right spindle box 10 is provided with a right grinding wheel adjustment unit 83 having the same structure as the left grinding wheel adjustment unit 77. In the present invention, the adjustment accuracy of the grinding wheel adjustment handwheels of the left and right grinding wheels is 0.05 mm per turn. The left grinding wheel adjustment handwheel 79 rotates clockwise, and the grinding wheel moves to the right. The right grinding wheel adjustment handwheel 79 rotates counterclockwise, and the grinding wheel moves to the left. The grinding thickness of the workpiece can be accurately adjusted by adjusting the position of the grinding wheel. After trimming the grinding wheel, the position of the left grinding wheel can also be adjusted by a knife edge ruler. For example, the size of the workpiece after vulcanization is 3.4 mm. The size requirement after grinding is 3.0. In order to ensure that the depth of the oil groove of the workpiece is consistent on both sides after grinding, the grinding amount of the left and right grinding wheels must be equal, that is, the plane of the left grinding wheel needs to protrude 0.2 mm from the plane of the angle plate, and a knife edge ruler is used to close the plane of the grinding wheel. A 0.2 mm feeler gauge is used to detect the gap between the knife edge ruler and the plane of the angle plate, and the position of the left grinding wheel is adjusted.

[0075] After the position of the left grinding wheel is adjusted, move the right spindle box to the left, close to the left grinding wheel cover, and adjust the grinding wheel in and out through the grinding wheel adjustment handwheel of the right grinding wheel to adjust the grinding thickness of the workpiece. The adjustment accuracy of the grinding wheel adjustment handwheel (fine-tuning handle) is 0.05mm / turn. To obtain higher adjustment accuracy, the dial indicator can also be placed on the right spindle box, with the dial indicator head against the end face of the sleeve. In this way, the adjustment of the machine tool will be more effective and intuitive. In addition, since the fine-tuning device adopts the transmission method of worm gear + screw nut, the backlash of this transmission method will generally reach 0.3mm, that is, the handwheel rotates about 6 turns to eliminate the reverse clearance. It is recommended to fine-tune the grinding size in the following way:

[0076] The size of the workpiece after grinding is 2.95mm. The customer requires a size of 3.0mm. In this case, the right grinding wheel needs to be retracted 0.05mm. It is recommended that the user's adjustment method strictly follows the following process: first loosen the sleeve locking bolt, tap it lightly backward to separate the sleeve locking bolt from the sleeve, then turn the handwheel clockwise for 10 circles to let the grinding wheel retract, and then rotate it counterclockwise for 9 circles. In this way, the gap of the fine-tuning mechanism can be eliminated and the grinding size adjustment can be completed quickly.

[0077] An observation window 85 is provided at the front end of the right spindle box 10 and the left spindle box 7, and a dust removal port 86 is provided at the rear end of the right spindle box 10 and the left spindle box 7. A cloth bag is provided at the dust removal port 86. The observation window 85 facilitates observation of the processing state, and the dust removal port 86 collects impurities generated by the processing into a cloth bag (not shown in the figure).

[0078] In addition, as a preferred embodiment of the present invention, sleeve locking units are provided in both the left spindle box 7 and the right spindle box to lock the sleeve. Each time the grinding wheel is fine-tuned, the handle must be loosened first and gently tapped to the rear side to disengage the locking sleeve device. When grinding a workpiece, the device must be locked to prevent the grinding wheel position from changing during grinding and causing the grinding size of the workpiece to be unstable.

[0079] When in use, if you want to remove the machine cover or the machine tool needs to be repaired, the machine tool must be turned off for at least 5 minutes before opening the cover. Regardless of any time during machine commissioning or maintenance, standard warning signs must be implemented for live circuit components. When performing periodic cleaning or preventive maintenance on the machine tool, the machine tool power supply and air supply must be disconnected, and the remaining air must be exhausted. Wait at least 5 minutes before starting the operation. When the machine tool is unattended or not used for a long time, the machine tool power supply and air supply must be disconnected. In an emergency, the user should press the emergency button to cut off the power supply and air supply to stop the machine tool. Release the emergency stop button and turn it in the direction of the arrow to open it.

[0080] The optimal working principle of the present invention is as follows:

[0081] A plurality of workpieces to be processed 100 (friction plates) are placed in a workpiece trough 20, and then the workpiece is pushed by the workpiece clamping cylinder 21, and the right motor 9 and the left motor 6 respectively drive the right grinding wheel and the left grinding wheel to rotate, and the workpiece 100 is pressed down by the workpiece insert plate 19, so that the pressed workpiece 100 falls from the feed port to between the left grinding wheel and the right grinding wheel, and is ground by the rotating right and left grinding wheels as the workpiece 100 falls, and slides out through the discharge port 12 after processing is completed, and a collecting tray can also be provided at the receiving trough 62 for collecting the processed workpieces.
