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)  Grinding wheel spindle
   Grinding wheel spindle adopts FA-G high-precision spindle bearing sleeve structure, without separate lubrication, simple maintenance, free of metal-to-metal contact, grinding wheel spindle has the characteristics of high rigidity and precision, can obtain nearly permanent service life. For special workpiece grinding, optional motorized spindle, with the function of increasing linear speed.
(4) Numerical control system
     Siemens numerical control system as the standard configuration, after secondary development, all Chinese operation interface, easy to use. Equipped with Siemens high performance servo motor, 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.
4.Installation environment requirment:

1	Power supply  voltage	380V
2	Installed machine ultimate capacity	15KW
3	Operating environment temperature	8-40ºC
4	Grinding fluid filtration method	Self-precipitation or combined filtration
5	Cooling water tank	0.37KW
6	Cooling water pump	120L

5. Double spindle machine:
6. Main characteristics of high precision cylindrical grinding machine:
1)  The body and components are cast by FC30 cast iron. After two manual annealing treatment. After natural aging treatment. Component processing adopts YASDA, MITSUI SEIKI, TOSHIBA, ELB and other world-class equipment one-time clamping processing. Precision size can be up to micron level, to ensure high precision equipment basic components.

2) Longitudinal and transverse table support base surfaces are machined entirely to achieve the highest level of accuracy. The worktable uses full support guide rail, which is characterized by good rigidity and large bearing capacity. Under the condition of high load, it can also run without error and with high precision.
