Abstract

The invention relates to a machine tool for the machining of a workpiece by means of a tool, wherein the machine tool is designed to clamp the tool for the machine-controlled machining within a machining program on the work spindle and to clamp the tool on the machine bench of the machine tool, characterized by a tool magazine which can be secured on the machine bench, on which a tool or a plurality of tools may be clamped individually in a replaceable manner.

First claim

1 . Machine tool for the machining of a workpiece by means of a tool, wherein the machine tool is designed to clamp the workpiece for the machine-controlled machining within a machining program on the work spindle and to clamp the tool on the machine bench of the machine tool, characterized by
a tool magazine which can be secured on the machine bench, on or at which a tool or a plurality of tools may be clamped individually in a replaceable manner.

2 . Machine tool according to patent claim 1 , characterized in that the tool magazine is designed so that different tools can be clamped in different directions on the tool magazine.

3 . Machine tool according to patent claim 2 , characterized in that the tool magazine has a substantially rectangular or cuboidal base body, on whose outer surfaces clamping means are provided for the clamping of the tool or tools.

4 . Machine tool according to patent claim 1 , characterized in that the tool magazine comprises at least one driving means by which individual or multiple tools can be driven independently of the movement of the machine bench.

5 . Machine tool according to patent claim 1 , characterized in that the tool magazine comprises a clampable pallet.

6 . Machine tool according to patent claim 5 , characterized in that the machine tool moreover comprises a pallet changer and a pallet magazine, especially a round or linear magazine, so that the pallet changer in combination with the round or linear magazine can bring about an automated interchanging of a plurality of tools which are clamped on the pallet.

7 . Machine tool according to patent claim 1 , characterized in that the machine bench is a swivel rotary table.

8 . Machine tool according to patent claim 1 , characterized in that the machine tool moreover comprises a wheel magazine, which is designed to store a plurality of workpieces and a changing mechanism by means of which the workpieces can be swapped in and out from the wheel magazine to the work spindle.

9 . Machine tool according to patent claim 8 , characterized in that the wheel magazine is moreover designed to hold tools and the changing mechanism is moreover configured to swap tools in and out from the wheel magazine to the work spindle.

10 . Machine tool according to patent claim 1 , characterized in that the machine tool is designed to fasten the workpiece to the work spindle by a tool interface, especially a HSK interface.

11 . Method for machining a workpiece on a machine tool with the steps:
Providing of a plurality of workpieces in a magazine, Swapping of one of the workpieces in the work spindle of the machine tool, Providing of a tool magazine with a tool or a plurality of tools, mounted on a machine bench of the machine tool And machining of the workpiece clamped in the work spindle with one tool or a succession of several tools kept in the tool magazine.

12 . Method for machining a workpiece on a machine tool according to patent claim 11 , characterized in that, for the replacing of the tools, the tool magazine with the tools stored therein is replaced by means of a pallet changer for another tool magazine with tools stored therein.

13 . Method for machining a workpiece on a machine tool according to patent claim 11 , characterized in that tools are also stored in the magazine besides the workpieces and a handling device is used to swap in workpieces and tools in the work spindle in alternating succession and workpieces are also stored in the tool magazine besides tools and the method involves the step of machining a workpiece clamped in the tool magazine by a tool provided in the work spindle.
