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

Features:
1.Each main spindle and each swing frame are driven independently.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 maximum inclination of 30º,this machine is best for polishing lens of high D/R.
3.Size and position of the eccenter stroke are easy to adjust.
4.Each working pressure is produced by adjustable pneumatic,pressure shows on pressure gauge.
5.Each timer controls the working time.It realizes automatic production.
6.Coolant or polishing slurry circulates to feed in one tank.
