The Specific Repair Method Of The Grinding Wheel

1. The cutting edge of the new grinding wheel must be corrected with a special correction plate (75*75*1) before use. Correction method: suck the correction plate on the workbench of the equipment, and cut the correction plate with a new grinding wheel installed on the equipment. The cutting depth of the new knife can be controlled at about 0.5 mm, and the cutting speed gradually increases from 5 mm/s to 30 mm/s, cutting about 30 lines in total (can be divided into 5 mm/s, 10 mm/s, 15 mm/s, 20 mm/s, 25 mm/s, 30 mm/s each gear speed repair 5 knives .
2. The corrected grinding wheel can be pre-cut on silicon wafers. When pre-cutting, the feed speed must be controlled at about 10-20 mm/s at the beginning (the speed that meets the requirements of the kerf), and then slowly increase the speed , always raise the feed speed to 180-200 mm/s, and the whole speed-up process takes about 1-2 hours; or at the required cutting depth, try cutting from a slow speed and gradually increase the speed on the scrap workpiece until After reaching the operating speed and meeting the requirements of the cutting seam, it will be put into normal cutting.
3. If after cutting for a certain period of time, when burrs appear in the slit, you can reduce the feed speed, and then slowly increase the speed; or use a correction plate to correct the blade (the main reason is: as the outer circle of the grinding wheel wears out, the edge corrected by the original grinding wheel Width is not enough), the depth of correction at this time must be determined by the wear of the cutting edge of the grinding wheel. When correcting, the outer circle of the flange should not touch the surface of the correction plate, otherwise the flange will be easily damaged.
4. If there is a lot of wear on the outer circle of the grinding wheel and the exposure of the cutting edge is not enough, please use a small flange instead. Edge correction must be performed after replacing the flange.
