CNC cylindrical grinder is designed with high efficiency, high accuracy and maximum operational convenience in mind.
The CNC Cylindrical Grinder Angular Wheel Head
(angular grinding) heavy duty type 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.
Angular Type Wheel Seat
Independent hydraulic and lubrication system with hydrostatic slideways and high precision ball screws ensure ultra-high positioning accuracy.
Wheel Spindle Hydrostatic Bearing
The hybrid hydrostatic bearings are used for the wheel spindle which prevent metal-to-metal contact and avoid vibration.”
G.W. Dressing
X and Z axis simultaneous movement dresses the wheel in specific shape for multiple step grinding purposes.
Rigid Work Spindle Head
The rigidly constructed work spindle head employs high precision bearings assuring maximum spindle stability. It guarantees outstanding accuracy for external and face grinding.
Uniform Load Distribution
There is uniform load distribution during face grinding and OD grinding.
Customised CNC Control system
Customised CNC Control System of FANUC/SIEMENS/MITSUBUSHI make the cylindrical grinding machines more reliable & flexible to operate.
Leak Proof Machine Guard
The cylindrical grinding machines are equipped with leak proof machine guard.
Compact Machine Footprint
The cylindrical grinding machines have compact machine footprint.
