2. Device description:
1) Ontology
   The body and components are cast by Milhanna high grade cast iron FC30, which is artificially normalized heat treatment and then treated by natural aging. 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)  Grinding wheel head feed shaft
  The grinding feed system is composed of a V and a flat track of hand-crafted precision shovel, with automatic lubrication system and C3 level precision grinding ball screw, which can achieve smooth movement, excellent repeated positioning accuracy and long track life.    


4) Grinding wheel spindle
   The grinding wheel spindle adopts FA-G high-precision bearings, the first four and the second two sleeve structure, without separate lubrication, simple maintenance, free of metal-to-metal contact, and can obtain nearly permanent service life. The grinding wheel spindle has the characteristics of high rigidity and high precision. For special workpiece grinding, the grinding wheel speed can be adjusted to increase the linear speed.

5) Tail seat
   The tail seat is designed to be both rigid and robust. A hardened alloy steel sliding cylinder encrusted in the cast iron body is designed to carry the MT4 top core. The jacking force of the sliding cylinder can be easily changed by adjustment knobs at the rear. Special accessories oil pressure tail seat with a pedal to facilitate unloading work parts.
6)  Matching device
    Equipped with inner hole grinding device for choice, inner hole spindle speed up to 20000 RPM, can achieve a good clamping to complete the grinding of outer circle and inner hole. At the same time, optional dual-axis optical ruler numerical control device, to achieve accurate 0.001mm feed.
