Positioning of workpiece and grinding wheel∗1

The pulse handle for positioning is equipped as a standard. The Workhead spindle and L/R axis operate in conjunction with the rotation of the pulse handle. Furthermore, semi-automatic function is also provided for easy positioning of tapered workpieces.

∗1: Synchronization function of workhead spindle and L/R axis by manual.

Corresponding to various machining

The rotary dress device behind the workhead spindle and our original grinding wheel-forming system enable various wheel shapes. The operator can set various shapes such as general standard screws, special shape screws, and ball screws with ease. Furthermore, our forming system corresponds to dress conditions that are suitable for rough and finish machining.
