Compact 4-shaft Upper Spindle Smoothing Machine UP-4S-15


Capable of polishing small diameter deep concave lenses with high precision

UP-4S-15 is a 4-shaft smoothing machine specialized for small-diameter lens manufacturing.

The R surface can be polished with high precision and minimal irregularity by applying pressure in the direction of the spherical center of the R surface to the lens grinding eye.
An easy-to-operate LCD touch panel, a pressure setting function, and a forward-positioned swing-width adjustment mechanism ensure easy operation.
By specializing in small-diameter lens manufacturing, this machine saves space on the processing floor and enables easy layout changes.
By using the optional constant dimension device, it is possible to control the lens wall thickness of ±0.01mm.
