Application:
Application:
Double side grinding and polishing for high hardness,thin,and high precision
product. metal or nonmetallic.
Like sapphire substrate, optical glass, quartz crystal, silicon wafer.
Principle and character
1, Using AC variable frequency motor to drive, soft start and soft stop,very stable.
2, Grinder with 4 steps in process:light/middle/heavy press and revise grinding.
3,Using button to operate and control, easily and simple.
4,Oil pressure lifting gear very stable,sun gear can adjust the position.
5,Designed a slow cylinder to load workpiece, avoid breaking and be controlled.
6,Can control the number of grinding turns with the pre-counter.
7,Can use diamond wheel to maintain the grinding wheel.
8,Good rigidity as the spindle is with higher dimension design.
