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.
