The layout of the machine is that its grinding wheethead is fixed and regulating wheehead is movabie.

The grinding wheel spindle is designed in cantilever structure and supported on muitiple long-secment hydrody-

namic oil-film bearing.

The regulating wheel spindle is also designed in cantilever structure and supported on conical sliding bearing with

1:30 taper in the front and rolling bearing on the back.

The regulating wheel feed slide is supported on dovetail needle roller guideway and a differential leadscrew is

used for performing feed motion.

AC frequency converter is used for changing the regulating wheel speed infinitely.

The machine is equipped with the plunge-cut mechanism.

The mounting surface of the workrest is located with T-slot.
