Precision Piano-type Surface Grinder

We are offering a wide range of Precision Piano-Type Surface Grinder.

1.Bed, table are made of high quality cast iron, with good guide precision.
2. Bed rail with organ type machine protection shield, good protective effect and long service life.
3. Bed and table rails lubricate automatically without pressure, and the oil flow can be adjusted.
4.The longitudinal drive of the table overcomes the weight of the long rod deflection, on the other hand, form a tank buffer and disc spring vibration buffer two buffer structure, overcome the impact of longitudinal movement reversing, reducing the effects of shock and vibration on the grinding. Hydraulic system equipped with hydraulic oil temperature control box regulate the oil temperature.
5. Grinding vertical feed slide uses a ball screw, driven by AC servo motor after deceleration, achieves the vertical feed motion.
6. The grinding spindle structure is the key of the grinder, directly affect the precision, roughness, waviness and grinding efficiency of grinding. The machine uses high-precision angular contact bearings into groups telescopic structure, the AC motor through V-ribbed belts and spindle unloading device drives spindle to rotate . This reduces the tension of the drive belt on the spindle, and guarantees precision and roughness of the grinding, and the machine also has a higher grinding efficiency. Grinding spindle bearings use the imported precision spindle bearings.
