Abstract
The invention relates to a tool for securing on a tool holder of a machine tool for machining vegetable and/or mineral materials, comprising a tool body which is equipped with a machining attachment that points in a tool feeding direction and comprises a cutting region, in particular a cutting element, and on which a fitting element for meshing with a mating element provided on the tool holder is formed on a support surface facing the tool holder. The dependability and operational reliability when using a machine tool can be ensured if the fitting element has at least two molded regions with different contour regions over the vertical course of the fitting element with respect to the support surface.
Claims19
A tool system for a machine tool for machining vegetable or mineral materials, the tool system comprising:
- a tool holder;
- a tool, including:
- a tool body including a supporting surface, the supporting surface being configured to engage the tool holder and a fitting element projecting from the supporting surface, the fitting element including a first molded region projecting a first distance in a first direction from the supporting surface, and the fitting element including a second molded region projecting from the first molded region a further distance from the supporting surface, wherein the first molded region has a first contour defined as an outline of the first molded region in a first plane normal to the first direction, and the second molded region has a second contour defined as an outline of the second molded region in a second plane normal to the first direction, the first contour being non-circular and different from the second contour;
- and
- a cutting element configured to be attached to the tool body;
- and
- wherein the tool holder includes a counter element formed as an indentation in the tool holder, the counter element including first and second indentation portions molded in the tool holder, the first and second indentation portions being configured to receive the first and second molded regions of the tool body, the first indentation portion being non-circular and complementary to the non-circular first contour such that engagement of the non-circular first contour of the first molded region with the non-circular first indentation portion prevents rotation of the tool relative to the tool holder.
A tool for fastening to a tool holder of a machine tool for machining vegetable or mineral materials, the tool comprising:
- a tool body including:
- a receptacle defined in the tool body and configured to receive a cutting element pointing in a tool feed direction;
- a supporting surface facing away from the tool feed direction for engagement with the tool holder;
- a fastener receiving bore defined in the tool body and extending through the supporting surface, the fastener receiving bore having a longitudinal bore axis;
- and
- a fitting element projecting from the supporting surface, the fitting element including a first molded region extending from the supporting surface and projecting a first distance in a first direction parallel to the longitudinal bore axis from the supporting surface, and the fitting element including a second molded region projecting from the first molded region a further distance from the supporting surface, wherein the first molded region has a first contour defined as an outline of the first molded region in a first plane normal to the first direction, and the second molded region has a second contour defined as an outline of the second molded region in a second plane normal to the first direction, the first contour being non-circular and different from the second contour;
- wherein the first contour is symmetrical about a first axis of symmetry;
- wherein the second contour is symmetrical about a second axis of symmetry;
- and
- wherein the first and second axes of symmetry of the first and second contours are angularly offset by an angle relative to one another about an axis parallel to the first direction.
