CNC Ultra Precision Grinding Machine UPG-NC series

SERIES line-up

400series・600series・800series    

Concept

Own-developed Variable Pressure adjusts type Hydrostatic slide system and Ultra-precise temperature control technology achieved more cross-to-ZERO accuracy.  

Feature

  • Minimized Table Float for Superior Surface Finish: The machine minimizes table float, ensuring that the table reverse point maintains the same height for consistent contact with the workpiece surface. This results in improved surface finishes. The variable hydrostatic slide system maintains a constant gap across all work areas, ensuring strong rigidity and stability.
  • Exceptional Straightness Accuracy: Achieves straightness accuracy of 0.4 μm over 800 mm on the cross axis and less than 0.5 μm per meter on the longitudinal axis (UPG408NC model).
  • Proven Flatness Performance: In testing, the machine demonstrated excellent flatness accuracy. By grinding workpieces placed at the left, center, and right sides of the chuck and measuring 8 points on each side (24 points total), flatness remained within 0.5 μm for all positions, showcasing its resistance to eccentric loads.
