CNC Cylindrical Grinders

Smaller machine space achieved with use of wheelhead traverse structure :
A wheelhead traverse structure requires a stronger foundation than a table traverse structure. Okuma’s high-rigidity technology meets the conditions needed for a wheelhead traverse structure to achieve a compact body.

CNC Cylindrical Grinders

Superior user-friendly design supports automation :
The upper portion of the front door can accommodate various loader positions. Line flexibility from the space-saving design also contributes to greater automation.

CNC Cylindrical Grinders

Hydrodynamic bearing provides for heavy-duty and highly accurate grinding—with shorter cycle times :
Non-round plain bearing wheel spindle with a dynamic pressure structure supports the wheel spindle with wedge-shaped oil film pressure that is generated by wheel spindle rotation. Retention strength is a powerful 1 t, in addition to which wheel rotation accuracy is kept to within 0.01 µm for a good balance of high accuracy grinding even in heavy-duty cutting. Also, because the wheel spindle has no metal contact, its original performance is maintained semi-permanently.

CNC Cylindrical Grinders

High machining efficiency maintained
with wide V—Flat guideway:
A widened V—Flat guideway system is used that expands the span between the V and Flat guideways beneath the saddle. Higher workpiece support rigidity enables grinding with full power of 7.5 kW (optional 15 kW). The grinding load on the wheelhead during heavy-duty grinding is supported by wide V—Flat guideway for high machining efficiency.
