Okuma - CNC Cylindrical Grinders | GPW/GAW Series

CNC Cylindrical Grinders | GPW/GAW Series

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.

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.

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.

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.

Machining time is shortened with high speed feed at the top level in the class

Structure with unrivaled high following characteristics gives high feed speeds of ø30 m/min on the X axis and 20 m/min on the Z axis. Shorter non-cutting times contribute to improved machining efficiency.

• X-axis feedrate: ø30 m/min
• Z-axis feedrate: 20 m/min
