With  decades  of  production  practice  and  through  long-lasting  exploration  and  summing-up  we  have accum- ulated lots of experiences and developed different finishing technologies for different  objects  and  requirements  of customers. We have set  up a special laboratory with  technicians specialized in research for finishing technology, so that we can offer our experiences to customers, propose a complete  finishing  technology  as  well  as  train  techni- cians free of charges for them.

Principles
of
Selection

1、For precision processing the abrasive with small grains should be chosen and for rough process- ing the abrasive with bigger grains should be used.
2、The abrasive should not be over big when used for processing small workpieces while the abrasi- ve 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.
