CONCEPT

The table structure is used by a linear motor on the longitudinal, and a variable static pressure slide system. 

It allows high speed turning and crowning grinding.

Ultra precision surface grinder that can perform on-machine measurement using accurate positioning.

Feature

・By using linear motor drive and variable oil static pressure slide for the longitudinal for tables, the speed can be freely controlled from stable low speed  of 40 m/min.

・Variety of options soft are available, including crowning, mulch works griding, measurement and correction grinding.

・The ultra-precision variable hydrostatic slide system minimizes changes in the guide-surface oil film.

　The flow rate of oil is flexibly controlled, and the change in oil film thickness is less than 1/7 compared to the conventional oil static pressure draft inner surface. In addition, less than 1/4 of the conventional amount of hydrostatic oil is used, making a significant contribution to improving accuracy and saving energy in temperature control.

・Suitable for ultra-precision machining and mirror finish by preparing the equipment environment.
