1. Salient features:
1.1.Grinding wheel and Regulating wheel
1.1.1.The wide grinding wheel can increase the grinding allowance in a single pass, and decrease repeating, to raise efficiency.
1.1.2.The frame of regulating wheel moves for adjustment and work piece fixed in order to equipped different feed devices.
1.1.3.The spindles of grinding wheel and regulating wheel adopted five-plate short bearing bushed static-hydrodynamical oil film bearing, which with better rigidity, and meet the need of heavy loading grinding and precise grinding.
1.2.Electric
1.2.1.The regulating wheel feed slide is equipped plastic coated guideway and servomotor that drives high-precision turbine reducer to work, through the couplings driving ball screws. The minimum feed is 0.001mm.
1.2.2.AC frequency converter is used for regulating wheel speed control .
1.2.3.Hydraulic transmission & stepless speed regulation are adopted on regulating wheel & grinding wheel dresser.
1.3.Cooling
The cooling system is equipped with magnetic coolant separator.
1.4. Machine body and design
1.4.1.Equipped automatic plunge device in the grinder.
1.4.2. Iron casting with high rigidity, natural aging.
