The modern high technology precision machines in use at the German sites in Übach-Palenberg and Wurzen allow production to be tailored with great flexibility to changing customer requirements. These include, among others, a large portal grinding machine of 28 m length and a variety of processing centers, on which large cast and wrought iron pieces weighing several tons can be worked. Cylindrical components many meters in diameter can be processed easily on the vertical boring and turning mills. Heavy crankshafts several meters long can be milled up to the grinding tolerance, on 5-axes simultaneously in one set, using one of the largest turning lathes and milling centers ever built. The following finishing work is carried out on a crankshaft grinding machine, which can grind crankshafts for every size of compressor. These machines allow finishing tolerances within a few hundredths of a millimeter to be achieved.
