Table feed mechanism eliminating ball screw waviness
For the sake of making stable high accuracy grinding possible over a long period of time, a JTEKT original table feed mechanism is adopted.
Straightness and surface texture is improved by notaffecting the table with ball screw waviness.

φ760mm 〜 φ1,065mm wheel specifications
We have prepared a wheel diameter of φ1,065mm to make the grinding of workpieces with significant swing possible.By using a wheel spindle with an even higher rigidity, machining with a wheel width of 300mm has been made possible.
