Product Description
MK11250 Wide Wheel Centerless Grinder
1. Salient features:
1.1.Grinding wheel and Regulating wheel
1.1.1.The diameter of grinding wheel is 600mm, with strong grinding force.
1.1.2.The 600mm wide grinding wheel can increase the grinding allowance in a single pass, and decrease repeating, to raise efficiency.
1.1.3.The grinder designed for double moving wheels, while grinding bracket fixed. The frame of regulating wheel moves for adjustment and workpiece fixed in order to equipped different feed devices.
1.1.4. 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.Gear motor driven the ball screw & stepless speed regulation are adopted on regulating wheel & grinding wheel dresser.
1.3.Cooling
1.3.1.The coolant system is equipped with magnetic coolant separator.
1.4.Control system
1.4.1.Touchable panel, automatic plunge-cut grinding, the load, speed, time and step level adjustable
1.4.2.PLC or CNC system optional.
1.5. Machine body and design
1.5.1. Equipped automatic plunge device in the grinder.
1.5.2. Iron casting with high rigidity, natural aging.
