Verfahren und Vorrichtung zum spanenden Bearbeiten von Stangen, Rohren oder Rohrluppen

摘要

The method is such that the workpiece to be machined, supported in the transverse plane of cutting, is milled longitudinally and peripherally, while the tool and workpiece are continuously longitudinally movable w.r.t. each other. At least one tool concentrically circulates round the fixed workpiece in a plane inclined to the work longitudinal axis and simultaneously machines two opposite regions of the workpiece surface by its cutting edges. Pref. with two adjacent tools, concentrically circulating round the work in two different planes, the latter are inclined to a common long work axis in mutually offset directions by 30 degrees .
