CNC cylindrical grinder is designed with high efficiency, high accuracy and maximum operational convenience in mind.
CNC-Plunge Grinding Series with Angular Wheel Head is
designed with high efficiency, high accuracy and maximum operational convenience in mind. The machine structure design fully meets ergonomic theorem for user-friendly operations.
Rigid and stable construction as well as a special wheel
spindle design are combined with advanced CNC control
to make cylindrical grinding easier and more accurate than ever before.
Rigid Work Spindle Head
The rigidly constructed spindle head employs high precision bearings assuring maximum spindle stability. It guarantees outstanding accuracy for external and internal diameter grinding (opt.) and face grinding.
Precision Wheel Spindle
The grinding wheel spindle is precisely machined from 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 Hydrostatic Bearing
The hybrid hydrostatic bearings are used for the wheel spindle. The highly rigid bearings design prevents metal-to-metal contact and avoids 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.
G.W. Dressing
X and Z axis simultaneous movement may dress the wheel in specific shape for multiple step grinding purposes.
