3D Polishing Machine

Medium-sized 3D Type Polishing Machine NMU-2P


Capable of polishing a wide range of lenses with high precision

The rigidity of this device is extremely high due to the lower axis position adjustment mechanism.

A wide range of uneven workpiece shapes can be processed with high precision.

The position of the lens relative to the Kanzashi in three directions (up/down, front/back, and angle) is adjusted on the main axis (lower axis), and a digital counter is synchronized to each adjustment axis to enable precise reproduction of the position of the kanzashi relative to the lens.
Since the kanzashi section does not need to be positioned in relation to the lens, the kanzashi section is more rigid than in conventional machines, enabling a smooth polished surface to be obtained.
