Rigid Spindle Head
The rigid constructed spindle head employs high precision bearings assuring maximum spindle stability.
It guarantess outstanding accuracy for external and interna diameter grinding and face grinding.
The spindle head on the OPTMUM series cylindrical grinder is driven by servomotor, providing variable speed change.
The spindle head allows for swiveling positive 90° and negative 30°.
Precision Wheel Spindle
The grinding wheel spindle is precisely machined form high quality a loy steel (SNCM-220), normalized, maximum wear resistance and lifetime accuracy are assured.tempered, carburized and sub-zero treated, precisely ground and mirror-effect treated. Hardness reaches to over HRC 62°. Non-deformation,
Wheel Spindle with Hydro-static Bearing Absolutely No Metal-to-Metal Contact
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.
Tailstock Lubrication System Simplifies Maintenance
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.
Precision Wheel Head
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.
