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) Automatic system:
   Standard use of Germany Siemens high-end CNC system, and after secondary development, fool type man-machine dialogue mode, with Siemens servo motor. There are many optional devices to choose from, including automatic end measuring device, automatic outside diameter measuring device, automatic hydraulic tailstock with pedal, automatic hydraulic chuck device, automatic grinding wheel balancing device, etc.
 

4) Grinding wheel head feed shaft:
    The grinding feed system is composed of Turcite coated V-flat track with precision spatula coupled with automatic lubrication system and precision grinding ball screw for smooth motion, excellent repetitive positioning accuracy and long track life.


5) Grinding wheel spindle:
    The grinding wheel spindle adopts high precision dynamic and static compression spindle, which has the characteristics of high rotary precision, high dynamic stiffness, good vibration resistance, high grinding efficiency and good grinding surface quality.
6) Tail seat:
    The tailseat 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.
7) Working head:
    The working head is a bearing type structure, the main shaft is fully sealed by the main shaft sleeve design, and then installed in a fixed position, and in the pulley outside the waterproof cover, can be waterproof, cutting fluid corrosion. Rotary cylinder can be installed, and can be matched with different workpiece clamp design to facilitate the grinding of different workpiece.
8)  Grinding wheel dressing method:
     Different grinding methods can be selected according to different grinding workpiece.
