一、Main Characteristics:

The layout of the machine is that the grinding wheel is fixed and the regulating wheel is movable.

The grinding wheelheads are designed in cantilever support and rolling bearing structure while the regulating wheelheads are designed in twin-grip and rolling bearing structure.

Linear rolling guideway are used for regulating wheel feeding guideway which is driven by servo motor through ball screw.

Diamond dressing roller is used for grinding wheel dresser. The rolling wheel is driven by servo motor.

The structure of servo motor driving ball screws is used for the grinding wheel dresser feed motions and reciprocation movements, both the feeding guideway and reciprocation guideway are straight-line rolling guideway.  

The  reciprocation speed of regulating wheel dresser can be steplessly varied with a speed-reduction motor equipped with frequency converter.

The movement of regulating wheelhead is driven by spindle motor.

The coolant tank includes a magnetic separator and paper filter.

The machine is equipped with Siemens servo system.

二、Main Application:

The machine is mainly used for through-feed grinding of cylindrical surface of ring and shaft-type parts, as well as for plunge-cut grinding of various stepped, conical and cylindrical surfaces in semi-automatic or full-automatic operation. It is suitable for small batch and mass production.
