Principles
of
Selection

1、For precision processing the abrasive with small grains should be chosen and for rough process- in the abrasive with bigger grains should be used.
2、The abrasive should not be over big when used for processing small workpieces while the abrasive should not be too small for processing large workpieces.
3、The hardness of  the  abrasive  should  be decided  according to the efficiency of processing and polishing consumption.
4、For processing the workpieces with holes or troughs, the abrasive should be 1.5 times large than the holes or troughs while the small abrasive should be 1/3 smaller than the holes or troughs.
5、The proportion of the abrasive and workpieces should be 2:1-5:1 and be adjusted according to rough or precision processing.
