YHDM750 Double Disc Grinding Machine
It is designed for grinding the two parallel side surfaces of the various high precise and thin work pieces with round and abnormal shape, no matter made of metal or nonmetal material, can be processed. Such as bearing, valve plate, seal, oil pump vane, piston ring, etc.
● CNC system chooses Siemens with friendly HMI and reliable performance.
● The parts’ processing for the upper and lower surfaces is simultaneous with high precision, and without assisted positioning ( such as disks )
● The program about the double disc grinding and wheel dressing control makes it to get high precision grinding.
● Wheel head feed adopts precise ball screw unit. Feeding precision: 0.001 mm.
● Wheel head spindle is driven by converter, 150-950r/min.
● The motor of the feeding carrier adopts converter control; the speed is 1-10rpm.
● The coolant is filtered by three steps including magnetic separation, paper tape filtering, sediment filtering two steps, cooling machine will be put into cycle use after temperature control.
● Adopt hinged carrier plate mechanism（Patent No:ZL200820052659.1）, which is easy to open to make a convenient replacement and dressing of the grinding wheel.
● The machine body adopts casting boxlike structure with good shock absorption and reliable rigidity and thermal stability; Wheel heads spindle are set by vertical configuration.
The device can be processed by a variety of special-shaped parts of the workpiece and the circular metal, non-metallic thin parts (bearings, valves, aluminum alloy plate, seals, oil pump blades, piston rings, etc.)
