It is mainly used for trimming and polishing dao parts, and is widely used in rough grinding, semi-rough grinding, fine grinding, super fine grinding, honing and other processing.
1. Coarse grinding and semi-coarse grinding. It is mainly used to process the workpiece quickly, the processing volume is large, and the surface finish requirements are not very high. According to the actual finish to be achieved, 16#180# particle size is generally used.
2. Fine grinding. You can choose the particle size 200#600#, if the roughness requirement is around Ra0.80.3, in order to improve the grinding efficiency, try to choose a slightly coarser processing.
3. Super-precision grinding. The roughness is within Ra0.2, the grinding amount is very small, and the precision requirements are also high. Selecting 800#1200# can achieve a more ideal effect.
4. Honing. Using 1200# fine oil stone, during the grinding process, the amount of feed control is relatively standard, the roughness needs to achieve the mirror effect, and the accuracy requirements are very high.
