Abstract
A combined skiver and a smooth rolling tool with a skiver head and behind this a smooth rolling head, wherein between the skiver head and the rolling head an exclusive torque transmitting coupling is located which restricts the allowable axis shaft offset and/or the angular position of the axes of the rolling head and skiver head, to which the rolling head is connected, characterized in that the skiver head (2) is guided through a workpiece bore via a hydrostatic guideway.
Claims8
A skiving tool, comprising:
- a tool head;
- at least one skiving knife;
- at least one counterforce generation element, by means of which a counterforce (Fg) to a passive force (Fp) acting on the at least one skiving knife can be generated;
- a knife holder onto which the at least one skiving knife and the at least one counterforce generation element are fixed;
- and
- at least one adjustment device by means of which a diameter of a circumscribed circle (D), on which a cutting edge of the at least one skiving knife is located, is infinitely variable,
- wherein the at least one adjustment device is configured with a motor such that the knife holder can be elastically deformed by the motor in such a way that the diameter of a circumscribed circle (D) changes, and
- wherein the knife holder is mounted to the tool head such that it can be moved in the radial direction relative to the tool head.

A skiving tool, comprising:
- a tool head;
- at least one skiving knife;
- at least one counterforce generation element, by means of which a counterforce (Fg) to a passive force (Fp) acting on the at least one skiving knife can be generated;
- a knife holder onto which the at least one skiving knife and the at least one counterforce generation element are fixed;
- at least one adjustment device by means of which a diameter of a circumscribed circle (D), on which a cutting edge of the at least one skiving knife is located, is infinitely variable, wherein the adjustment device comprises a motor for electronically changing a diameter of a circumscribed circle (D);
- and
- a position control that is connected to the adjustment device and a diameter determination device, wherein the position control is configured to automatically adjust a diameter of the circumscribed circle (D) to a nominal diameter that can be predefined, and
- wherein the knife holder is mounted to the tool head such that it can be moved in the radial direction relative to the tool head.
5 more elements
A skiving tool, comprising:
- a tool head;
- at least a first skiving knife, a second skiving knife, and a third skiving knife;
- at least one counterforce generation element, by means of which a counterforce (Fg) to a passive force (Fp) acting on the first skiving knife can be generated;
- a knife holder onto which the first skiving knife and the at least one counterforce generation element are fixed;
- a torque transmitting device connecting the tool head and the knife holder;
- and
- at least one adjustment device by means of which a diameter of a circumscribed circle (D), on which cutting edges of the first skiving knife, the second skiving knife, and the third skiving knife are located, is infinitely variable;
- wherein the knife holder is mounted to the tool head such that it can be moved in the radial direction relative to the tool head, and
- wherein the at least one adjustment device includes a motor.
