Technical characters：
● 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.
