CNC cylindrical grinding machine series
Rigid work spindle head
The rigid constructed spindle head employs high precision bearings assuring maximum spindle stability. It guarantess outstanding accuracy for external and internal diameter grinding (opt.) and face grinding.
Precision wheel spindle
The grinding wheel spindle is precisely machined form high quality alloy steel, normalized, tempered, carburized and sub-zero treated, precisely ground and mirror-effect treated. Non-deformation, maximum wear resistance and lifetime accuracy are assured.
Wheel spindle hydro-static bearing
The hybrid hydro-static bearings are used for the wheel spindle. Metal-to-metal contact will never occur with these highly rigid bearings design and also avoid vibration.
Tailstock lubrication system
An automatic oil bath lubrication system has been provided for the tailstock to maintain high-level accuracy. An oil level gauge enables quick oil status checking.
