1. Grinding and leveling stage Note:

A. A large amount of water is required during the grinding process of the machine (to avoid the temperature is too high)

B, excretion (avoid throwing on the mud)

C, pumping (the grinding machine can be ground in a clean place)

2. Grinding optimization stage:

The purpose of optimization is based on high light output

Gloss after grinding 50#, 150#, 300#, must be no less than 25 degrees, (this is no less than three times in each number of cross grinding)
