Product Information

High Precision Aspheric and Free-form Surface Grinder ULC/ULG Series, LG Series

The ULC/ULG series has been developed with the goal of turning and grinding free-form surface (f-θ lens) and asphere lenses as well as their respective molds with high efficiency and high precision. Moreover, as shown in the figures below, optimized machine structure and options are available for various applications and high cost performance is achieved.

LG-100 Series

  • Rough and semi-finishing are effectively executed as pre-process uses for high precision machining via ULG Series machines. 
  • Mutual utilization of part programs with ULG Series is available.
