Abstract

A device for machining workpieces a machining tool, a first workpiece-guiding element and a second workpiece-guiding element. The first workpiece-guiding element and the second workpiece-guiding element are designed to guide a workpiece, in a defined way, relative to the machining tool. The machining tool has an axis of rotation and a co-axial opening. The machining tool rotates about the axis of rotation for machining the workpiece. The first workpiece-guiding element is arranged in the opening of the machining tool co-axially to the axis of rotation.

First claim

1 . A device for machining workpieces, comprising
a machining tool; a first workpiece-guiding element; and a second workpiece-guiding element, wherein the first workpiece-guiding element and the second workpiece-guiding element are configured to guide a workpiece relative to the machining tool in a defined manner, wherein the machining tool has a rotational axis and a coaxial opening, wherein the machining tool rotates about the rotational axis for workpiece machining, wherein the first workpiece-guiding element is arranged in the opening in the machining tool so as to be coaxial with the rotational axis, and wherein the radius of the first workpiece-guiding element substantially corresponds to the protrusion of the machining tool.

2 . The device according to the claim 1 ,
wherein the first workpiece-guiding element is an element selected from the group consisting of a cylindrical element, a rod-shaped element and a pin-shaped element, or a combination thereof, and/or wherein the second workpiece-guiding element is a planar element.

3 . The device according to claim 1 ,
wherein the first workpiece-guiding element is configured to be static or so as to move or rotate together with the workpiece.

4 . The device according to claim 1 , wherein at least one of the machining tool and the first workpiece-guiding element is configured to be detachable and interchangeable.

5 . The device according to claim 1 ,
wherein the first workpiece-guiding element has a change in a diameter thereof, along a longitudinal axis thereof in parallel with the rotational axis.

6 . The device according to claim 1 ,
wherein the machining tool is configured as a hollow cone or has a defined conical lateral contour, wherein, inside the hollow body, the first workpiece-guiding element is arranged so as to be substantially not in contact with the machining tool.

7 . The device according to claim 1 , the device further comprising:
a drive means for the machining tool, wherein the machining tool is detachably connected to the drive means, and wherein the drive means is configured as a hollow drive shaft.

8 . The device according to claim 7 ,
wherein the second workpiece-guiding element is configured as a work table, wherein the work table is movable in parallel with the rotational axis, and/or wherein the surface of the work table is perpendicular to the rotational axis, and/or wherein the work table is configured such that a surface normal thereof is configured to pivot relative to the rotational axis such that the surface normal and the rotational axis are arranged so as to be non-parallel.

9 . The Device according to claim 1 ,
wherein the first workpiece-guiding element comprises an interchangeable tip or end region having a greater diameter than at least one of the first workpiece-guiding element and a ball bearing-mounted guide wheel.

10 . The device according to claim 1 ,
wherein the machining tool has a defined profile geometry to transfer said geometry to the workpiece to be machined.

11 . The device according to claim 1 ,
wherein the device has a discharge option for carrying away chips that accumulate.

12 . The device according to claim 1 ,
wherein the device is configured to be hand-held or stationary.
