Upper Shaft Spherical Core 2-shaft Smoothing Machine with Automatic Conveyor UPA-2S-50-75D


Automatic processing of deep concave lenses with high precision

「中型上軸球芯加圧研磨機 UP-2P-50」の搬送機付きモデルです。投入トレイごとの連続加工が可能です。

The lens grinding surface is always pressed perpendicularly toward the sphere center to shorten the processing tact time and produce a high-precision radius surface with minimal irregularity, which is particularly effective when grinding concave surfaces.
Processing conditions are NC-controlled to ensure high reproducibility in setup changes.
By manually loading the lens tray, the transporter automatically loads the workpiece into the processing section, processes it, and stores it in the tray.
