Application:
For lapping and polishing spherical / plane surface of optical glass, quartz glass, crystal, electrical elements and other brittle materials.

Features:
1.Main spindles are driven independently in SC120.4.Three main spindle  linkage control in SC120.6. 
The main spindle speed are infinitely variable,speeds show on digital display.
2.Main spindles can be adjust to incline from 0º to 30º.It can adapt different curve of lens.
   With Max inclination of 30º,this machine is best for polishing lens of high D/R.
3.Size and position of the eccentric stroke are easy to adjust.
4.Working pressure is produced by adjustable pneumatic,pressure shows on pressure gauge.
5.Timers control the working time.It realizes automatic production.
6.Coolant or polishing slurry circulates to feed in two containers.
