UPC 300

Ultra-precise machining of freeform optics



Introducing the UPC 300 / UPC 700

The compact UPC 300 is a three axis machine (X, Z, C) designed for the highly dynamic machining of freeform surfaces. The optional long stroke Fast Tool increases significantly the productivity in freeform machining. The Fast Tool can process a wide range of freeform geometries without
the need of time consuming Slow Tool machining - productivity and accuracy are combined in a very unique way.

The optional Y-axis turns this machine into an UPC 700 enabling additionally diamond milling and ruling of complex freeform geometries or micro features for maximum machining flexibility.

A high-quality optical metrology system allows for the machine integrated contactless measurement of freeform surfaces. In combination with the unique data handling capabilities a corrective remachining of freeform surfaces is possible to achieve highest precision.
