DDG 450 / 600

Double-sided Surface Grinding to Perfection

Highly competitive, with its space saving footprint, high precision and extremely cost effective design. The double-disk surface grinding machines in the new DDG product range from PETER WOLTERS offer economic effectiveness at its best.

Where ever a simultaneous grinding of parallel surfaces is required for a variety of work pieces. Two models, one pledge: long lasting precision from the first to the last part. Even under the harshest operating conditions. Various grinding processes are available for the machining of different work pieces.
