Features :
- 1. Rigid Spindle Head
- (1) The rigid constructed spindle head employs high precision bearings assuring maximum spindle stability.
- (2) It guarantess outstanding accuracy for external and interna diameter grinding and face grinding.
- (3) The spindle head on the OPTMUM series cylindrical grinder is driven by servomotor, providing variable speed change.
- (4) The spindle head allows for swiveling positive 90° and negative 30°.
- 2. Precision Wheel Spindle
- (1) The grinding wheel spindle is precisely machined form high quality a loy steel (SNCM-220), normalized, tempered, carburized and sub-zero treated, precisely ground and mirror-effect treated. Hardness reaches to over HRC 62°. Non-deformation, maximum wear resistance and lifetime accuracy are assured.
- 3. Wheel Spindle with Hydro-static Bearing Absolutely No Metal-to-Metal Contact
- (1) Hybrid Palmary hydro-static Bearings are used for the wheel spindle bearings. Metal-to-metal contact will never occur with these highly rigid bearings which have a damping effect and make 0.5μm the new definition of wheel spindle rotational accuracy.
- 4. Tailstock Lubrication System Simplifies Maintenance
- (1)An automatic oil bath lubrication system has been provided for the tailstock to maintain high-level accuracy. An oli level gauge enables quick and sure oil level checks.
- 5. Precision Wheel Head
- (1) The grinding wheel spindle is precision machined from high quality alloy steel (SNCM-220), normal zed, tempered, carburized and sub zero treated, precision ground and mirror-effect treated. Hardness reaches to over HRC 62°, No deformation, maximum wear resistance and lifetime accuracy are assured.
