A unique mechanism allows for fine adjustment of the kanzashi position for better reproducibility.
A mechanism that allows the angle of the plate axis to be varied by 0 to 30° in 2-axis units minimizes changes in NR.
Polishing Machine
Medium-sized Variable Tilt-axis 4-shaft Smoothing Machine NM-4S
NAGATA SEISAKUSHO CO., LTD.
Workability of mass-produced lenses is improved by a processing tank that can be tilted in 2-axis units.
This is a 4-shaft polishing machine designed for high-speed polishing of single lens for medium-sized lenses.
