1.1 Grinding wheel and Regulating wheel
1.1.1.Structure of fixed grinding wheel and movable regulating wheel
1.1.2.The grinding wheel designed in cantilever type, and its spindle adopted multi-plate long bearing bushed static-hydrodynamical oil film bearing.
1.1.3.Cantilevered regulating wheel, the spindle supports solid bearing sliding with 1:30 taper.
1.1.4.The swallow tailed roller guideway & differential screw supports the regulating wheel feeding
1.2.Electric
1.2.1.AC frequency converter is used for regulating wheel speed control .
1.2.2.Hydraulic transmission & stepless speed regulation are adopted on regulating wheel & grinding wheel dresser.
1.3. Machine body and design
1.3.1. Equipped automatic plunge device in the grinder.
1.3.2. Iron casting with high rigidity, natural aging.
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 that the conicity less than 1:20 .
