Polishing Machine

Medium-sized 4-shaft Variable Tilt-axis Semi-automatic Smoothing Machine NS-60TC-4S-Ⅱ


Lower axis tilting machine capable of automatically processing lenses in 4 processes

Automatic conveyor with inverting function enables continuous processing of the front and back sides of each input tray.

Lenses are automatically transported by manually loading the lens tray and processed by the kanzashi.
NC control is employed for the oscillating motion of the kanzashi, enabling advanced processing operations and setting of the kanzashi’ positions.
The processing method of the conventional diagonal-shaft polishing machine is followed, which facilitates smooth setting of the processing conditions.
The tilting axis is equipped with a counter to ensure high repeatability in setup changes.
