UGC
Small capacity ID Grinder

The Weldon UGC is a small part CNC grinding system ideally suited for internal, external and face grinding in a chucking mode. An optional “C” axis package provides non-round (cam) grinding capability.

Designed for the use or conventional or super abrasives, the UGC can accommodate both diamond and CBN grinding wheels.

The UGC can be equipped with up to three (3) grinding spindles for multiple feature grinding (bores, outside diameters, faces, etc.) in a single set-up.

Typical applications include small gears, rings, wear plates, bushings, valve components, and bearings.
