Verfahren und Vorrichtung zum Formstechen und Formdrehen

摘要

The invention concerns a special process and a device for the form cutting and form turning of work pieces. It is proposed, for a processing of this type for the purpose of production of unround geometries of this type as well as also work pieces as also the machining tool to rotate with a precisely defined opposingly radially spacing, preferably in the like direction of rotation, and thereby the number of rotations of the two rotating components with a determined like rotation number relationship so to correspond with respect to each other, that a simple cutter of the machining tool during its orbit about 360 DEG comes into contact with the work piece to be machined only in a partial sector of an "active" sector. Thereby it is so controlled according to the invention within this machining sector and forcibly guided by means of a curve disk in a radial plane, that out of the relative movement to the rotating work piece the geometry to be machined is produced. With the device according to the invention complicated face side penetrations or, as the case may be, peripheral penetrations from behind, can be produced with a large number of unround shapes in a short processing time with a very high trueness to the original form.
