Abstract
Instead of receiving universal joint crosses (1) like in the prior art in a special chuck of a turning machine and machining one respective pinion (2) and subsequently cycling the work piece by 90°, a contact surface (18) with a clamping device (19) is provided in the operating area according to the invention, wherein the raw part can be placed on the clamping device and can be clamped so that two opposite faces can be machined in this first clamping step including machining centering boreholes, wherein clamping is performed thereafter between centering points (22) at the centering boreholes for machining the adjacent enveloping surfaces.
