6.High precision CNC cylindrical grinding machine main featute:
1) Ontology:
 The body and components are cast by FC-25 cast iron. After two manual annealing treatment. After natural aging treatment. Components are processed by YASDA, MITSUI, SEIKI, TOSHIBA, ELB and other world-class equipment once clamping processing. Precision size can be up to micron level, to ensure high precision equipment basic components.

2) Automatic lubrication system:
  Machine guide rails and precision ball screws are continuously lubricated by automatic lubrication system to ensure longer service life and accuracy. The cooling system is separated from the body to eliminate vibration and favorable heat dissipation.
3) Automatic system:
 Customized, highly automated grinding system with a wide selection of options, including automatic end measuring device, automatic outside diameter measuring device, hydraulic tailstock device and highly integrated automatic loading and unloading system.
4) Grinding wheel head feed  shaft:
 The grinding feed system is composed of a V and a flat track with precise hand cutting, automatic lubrication system, precision ball screw, high precision and high power servo motor. It has the characteristics of smooth movement, excellent repeated positioning accuracy and long service life of the track.
