The invention relates to an adjusting device for the tool holder of a lathe and the like can be driven by a cam disk via an auxiliary slide.

In the case of a machine tool, for example, chisels in a chisel head are used for setting usually on the head itself adjustment means, such as microscrews, are attached which directly onto the chisel works. The adjustment means then form on the head near the chisels, especially if there are several Chisels are available and adjustability in different directions is required larger number of protrusions. These protrusions can be very annoying because chips get caught in them can, so that these points must be observed and the chips must be removed in good time. It is the constant presence of operating personnel is required, especially during processing certain metals, such as high-alloy steels, which produce very long, fine chips, the chips impossible ao can be easily removed by breaking and other mechanical devices.

In addition, there are the adjustment means, such. B. micrometer screws in these conventional devices at points that result in the automatic readjustment desired with full automation less suitable in accordance with the deviations found in the processed product.

In a known setting device with several holders for one tool each, the tools can act on the workpiece at the same time, each tool is operated by a separate one Driven cam disc. However, only one of the two tools acting on the workpiece can Machining one level of the workpiece, there are therefore only limited machining options.

The invention is based on the object of creating an adjusting device in which the action of the tools is not limited to just one plane of the workpiece, but in the case of the setting device It does not become any more complicated than the known one, with adjusting means for each tool in a simple manner are provided, which are located at a location remote from the holder, so that the setting the tools in relation to the workpiece is also possible during operation.

According to the invention, this object is achieved in that the one with a plurality of tools provided holder is arranged on an adjustable slide with one of the number the tools corresponding number of adjustable stops is provided, each of which is a switching adjustment device for the tool holder of a lathe and the like.
