Zerbst DP3/ S3 Facing centre lathe

ZERBST DP 3/S 3 Facing Centre Lathe DP 3/s 3- the Model 3 lathe

with triple-track longitudínal bed of the DP lathe system
We have commítted to meetíng customers specífíc requírements. Our approach of designíng functíon modules such that they can be variably arranged relative to each other permíts excellent matchíng to machíning jobs and component sízes. This advantage is particularly relevant in the productíon of bulky components. Also conventional manual operator control comes ín useful in such applications. The triple-track bed accommodates one or two saddles wíth varíous slíde configuratíons, steady rests, roller steadíes, and taíl- stocks. Thus, contínuous and accurate contours are readíly machíned even on extremely long components such that the desíred surface finísh is obtaíned. DP/S3 lathe models are the bargaín alternatíve to heavy-duty lathes.
