Abstract
The invention relates to an axially-functioning grinding tool (10) for fastening on a rotary shaft (14), wherein the tool (10) comprises an inner rotating area (11) and an outer rotating area (12). The inner rotating area (11) supports a cylinder-shaped grinding device with several layers of a grinding device support, which are arranged concentrically around the longitudinal axis of the rotating shaft (14). The outer rotating area (12) is provided with radially arranged strip-shaped grinding devices.
Claims28
An axially-functioning grinding tool for being fastened to a rotating shaft, characterized in that
- the grinding tool comprises an inner and an outer rotating area, wherein
- the inner rotating area has a cylinder-shaped grinding device with several layers of a grinding device support, which are arranged concentrically around the longitudinal axis of the rotating shaft, and
- the outer rotating area has radially arranged strip-shaped grinding devices.
The grinding tool in accordance with one of the preceding claims, wherein the strip-shaped grinding devices project past the cylinder-shaped grinding device.
The grinding tool in accordance with one of the preceding claims, wherein the cylinder-shaped grinding device primarily grinds by means of its front face.
The grinding tool in accordance with one of the preceding claims, wherein the strip-shaped grinding devices consist of flexible grinding device supports, which are provided with grinding devices at the upper edge or on one lateral face.
The grinding tool in accordance with one of the preceding claims, wherein the strip-shaped grinding devices are arranged in a tab shape along the circumference of the grinding tool.
The grinding tool in accordance with one of the preceding claims, wherein the outer rotating area has radially-oriented depressions for fastening the strip-shaped grinding devices.
The grinding tool in accordance with one of the preceding claims, wherein intermediate layers are used for fastening the strip-shaped grinding devices.
A material processing machine with a drive motor and a rotating shaft, on which an axially-functioning grinding tool in accordance with one of the preceding claims is fastened.
A method for processing a workpiece with at least one surface and one edge, wherein the following steps are performed:
- linear movement of the workpiece,
- cross-grinding of the surface of the workpiece by means of a multiple-layered cylinder-shaped grinding device arranged concentrically around a rotating shaft,
- edge grinding along the edge of the workpiece by means of strip-shaped grinding devices arranged in a radial direction in respect to the rotating shaft,
- wherein the linear movement, the cross-grinding and the edge grinding are simultaneously performed.
