M1080B china factory manufacture centerless grinder

Structure of fixed grinding wheel and movable regulating wheel

The grinding wheel designed in cantilever type, and its spindle adopted multi-plate long bearing bushed static-hydrodynamical oil film bearing.

Cantilevered regulating wheel, the spindle supports solid bearing sliding with 1:30 taper.

The regulating wheel feed slide is supported on roller guideway.

AC frequency converter is used for regulating wheel speed control .

Hydraulic transmission & stepless speed regulation are adopted on regulating wheel & grinding wheel dresser.

Equipped plunge device in the grinder.

Main Application:
The grinder is mainly used for through-feed grinding of cylindrical surface and ring-type parts, as well as for plunge-cut grinding of various stepped, cones by manual operation .
