3. 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
    Customers can choose automatic online end face measuring device, automatic online outer diameter measuring device, automatic hydraulic tailstock, automatic loading and unloading robot, inner hole grinding device, etc., according to the actual workpiece needs.

Automatic on-line end measuring device                                   Automatic on-line outside diameter measuring device    

(4)  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.
(5)  Grinding wheel spindle
     Standard grinding wheel spindle adopts bearing type, four front and two back structure, angular contact German F-AG bearing, with lubrication function. High precision dynamic and static pressure spindle can also be selected, which has the characteristics of high rotation precision, high dynamic stiffness, good vibration resistance, high grinding efficiency and good grinding surface quality. For special workpiece grinding, the grinding wheel speed can be adjusted, up to 3500 RPM and 65m/s.

(6)  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.
(7) Numerical control system
     Germany Siemens CNC system, with Siemens high performance servo motor, so that the equipment CNC system and drive system have better compatibility, at the same time with automatic sand repair and automatic compensation function, to ensure the stability and precision of feed and grinding.
