The machine structure is strengthened with same design of heavy duty cylindrical grinder. The enlarge hydrostatic wheel spindle construction could equip max. 125 mm width grinding wheel for plunge grinding application.
The enlarge hydrostatic wheel spindle construction could equip max. 125 mm width grinding wheel for plunge grinding application. The variable frequency grinding wheel speed control could reach max. 60 M/s cutting speed.
The enlarge splash guard allows interior to equip the auto loading and unloading device. It also has the added benefit of shorter cycle time and space saving.
All Hydro-static slides designed for smooth move while grinding process. The taper fine adjustment tailstock is standard accessory and easy to adjust the taper if required.
The CNC conversational controller is ease of operation. The optional accessories such as O.D. measuring system is possible to equip for clients use.
