Polishing Machine

Medium Sized 2-shaft Upper Spindle Spherical Center Polishing Machine UP-2P-50


High-precision polishing of deep concave lenses by spherical-center pressure oscillation

UP-2P-50 is an upper shaft spherical center oscillating polishing machine with a maximum installed tool diameter of φ100 mm, which was developed based on our original design.

UP-2P-50 is especially effective on concave surfaces because the polished surface of the lens is always pressured perpendicularly toward the center of the radius. This enables the processing of high-precision surfaces with minimal irregularity.
The mechanism for adjusting the swing width of the upper shaft oscillation is located at the front of the machine to facilitate adjustment work.
