Features
|
- Stable and Rigid Spindle Head
- The spindle runs on precision bearings, assuring maximum spindle stability. It guarantees outstanding accuracy for external and internal diameter grinding and face grinding.
- The spindle head swivels +90°~-30°.
- The spindle head on the 20 series machines provides variable speed changed by frequency inverter.
- The spindle head on the 32 and 42 series is driven by servomotor, providing variable speed.
- Precision Wheel Head
- The grinding wheel spindle is precision machined from high quality alloy steel SNCM-220, normalized, 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.
