The "PMR-80 model" is an NC centering plate alignment device that achieves high-precision plate alignment through centripetal oscillation and standardization of work processes and skill-less operation via digital control. By using a holder-type plate alignment tool that has the same shape as the lens, plate alignment can be performed under the same setting conditions as the lens processing conditions. We accept tool production. Please feel free to consult us. 【Features】 ■ Plate alignment and adjustment of processing plates using fixed plate and holder-shaped alignment tools ■ Single-axis model = space-saving ■ Can be installed in the space of a surface grinder ■ Oscillation condition input via touch panel ■ Numerical management = standardization of work processes and skill-less operation *For more details, please refer to the PDF document or feel free to contact us.
