In the processing of hardware and electronic components, automatic polishing machine is a kind of equipment widely used. It is composed of base, polishing disc, protective cover, electric control part, hydraulic part and fixture. In the process of product processing, there are certain requirements for abrasives, that is, the automatic polishing machine needs to be used with abrasives.

When the automatic polishing machine is used for processing, the polishing abrasive shall maintain a certain toughness, that is, the abrasive particles of the abrasive shall have the ability to resist fracture when subjected to force or impact.

Just like human joints and ligaments, this toughness can play a certain protective role for the machine, so that the automatic polishing machine and abrasive micro edge can maintain the cutting performance. Even if the machine becomes passivated, its broken surface can produce new cutting micro edge, so as to continue to maintain a sharp state and complete the cutting. If the brittleness of polishing abrasive is large, it will be damaged before fully playing the cutting role.

Abrasive toughness largely depends on its crystalline state, defects such as cracks and pores in crystallization, crystal size, macro geometric formal shape of abrasive and granulation method.

It can be seen that the polishing abrasive of the automatic polishing machine has a direct impact on the polishing effect of the equipment. Xinmeisheng suggests that consumers must test the performance of the abrasive when purchasing the polishing abrasive to effectively ensure the best polishing effect.
