2. Machine tool accuracy:

No.	Grinding mode	Work piece size (MM)	Flatness	parallelism
1.	Through grinding	Standard sample	≤0.001mm	≤Ra0.2
2.	Entry grinding(press grinding)	Standard sample	≤0.002mm	≤Ra0.2

 Note: Rough grinding (generally grinding amount 0.05~0.15mm); Fine grinding (generally 0.005~0.02mm)
3.Spindle:
Use the spindle of well-known brand. The spindle is made up of SNCM-21H alloy steel, whose hardness reaches up to HRC-62° with a harden layer of over 1.5mm, after a quenching-tempering, carburizing heat treatments, and computer-control deep hardening.
The spindle is of hydrodynamic oil bearing, with a run out less than 2um.

4. Regulating wheel transfer system:
The regulating wheel spindle uses a servo driving motor (YAS KAWA) of brand delta, with a variable rotary speed within 0-350 rpm (digit control). When the wheel diameter changes during grinding, the wheel linear speed can still keep the constant and the optimum, to make sure the best grinding quality.
The servo motor is smartly assembled in the regulating wheel holder, and drives the spindle directly through synchronous belts, with the same tilting angle as the wheel, to keep parallel all along for the two belts, which can avoid inertia loss, and some other inconvenience brought by the old-type chain transfer system. Neither don't have to change the chain and spring often.
