3D Smoothing Machine

Medium-size 2-Shaft Smoothing Machine NS-3D-50C

NAGATA SEISAKUSHO CO., LTD.

Capable of polishing a variety of lenses with high precision

This is a medium-sized two-shaft smoothing machine with a maximum installed tool diameter of 150 mm.

The lower axis is used to adjust the position of the lens relative to the kanzashi in three directions: up/down, front/back, and angle.
The kanzashi part is more rigid than conventional machines because it is not necessary to adjust the position of the kanzashi part in relation to the lens. This makes it possible to obtain a smooth polished surface.
The upper axis is matched to the lower axis with a high degree of accuracy, and the machine has very few axial and mechanical differences.
Even when processing by moving the work axis, the same lens surface with the same accuracy can be obtained under the same conditions and jigs.
By using the constant dimension device*, it is possible to control the lens thickness of ±0.01mm.
