PRODUCTS
- Stable, high-accuracy grinding
- Traditional Okuma 5-sided hydrostatic guideway
- Both cross-slide and table always raise with oil to achieve high follow-up accuracy.
- Higher rigidity with support on 5 sides from upper and lower portions of slide.
- Distance between two guideways is wide, and vibration absorption characteristics are improved simultaneously with high speed and high rigidity.
- With closed structure holds top and bottom solidly in place, accuracy and guideway durability are improved.
- The best machines for die/mold contour grinding.
- Thermo-Friendly Concept
- The Thermo-Friendly Concept delivers high machining accuracy with a unique machine construction design and thermal deformation control technology. The Thermo-Friendly Concept releases you from bothersome dimension compensation and warming-up, and provides outstanding dimensional stability even during long-time operation or changes in the plant temperature environment.
- Achieves high thermal stability not only during room temperature change, but also at machine startup and restarts.
- Thanks to stabilized thermal deformation, warming-up time is shortened and the burden of dimensional correction during machining restart is reduced.
※ This (TFC) is not available with 4WS and belt-driven grinding wheel specs.
※ The above are actual examples. Your results may vary due to differences in specifications, tooling and cutting conditions.
- Greater machining efficiency
- Benefits of numerically controlled oscillating traverse
- Higher removal rates, lower cycle times
- Improved surface roughness compared to conventional traverse grinding
- Ideal for long workpieces
-
- 2-wheel spindle (2WS)
-
Expanded range of uses for grinding wheel, including cylindrical and internal grinding, roughing, and finishing.
-
- 4-wheel spindle (4WS)
-
Up to 4 high frequency grinding wheel spindle sets can be mounted, enabling greater diversity of integrated grinding operations than with 2WS, and more efficient grinding.
