Semi-automatic circular grinders are intended for outer grinding of workpiece’s cylindrical and low-taper conic surfaces by plunge-cut and longitudinal method of grinding under conditions of simple, serial and mass production.
On the semi-automatic machine the following functions are automatic and mechanized: plunge-cut and longitudinal methods of grinding; variation of cross-cut, longitudinal and circular feedings; workpiece start-up and stop; engagement and disengagement of cooling fluid; rapid advance and retraction of grinding wheel head and tailstock movable sleeve; grinding wheel head travel along the screw; grinding wheel balancing.
