Definitions
- the invention relates to a tool and a method for machining workpieces, as specified in the respective preambles of claims 1 and 6, in particular for simultaneous multiple machining of workpieces, and a cutting device according to claim 10 and a use according to claim 12.
- cutting and separating processes are carried out using rotating tools that are used in stationary or mobile devices.
- CONFIRMATION COPY Separation process created surface quality of a cut surface does not meet the requirements in laboratories in which the cut surface generated as a result of the process is to be examined in more detail. Also in industrial production, clean, burr-free cut surfaces are required for further processing of separate workpieces, which should be as free as possible from any kind of damage. Post-processing of the cut surface in question, for example by a grinding or polishing process, is usually still necessary. Individual influences in the
- the tool When cutting by means of rotating tools, the tool plunges into it in a radial working direction
- a small thickness in the axial direction is desirable for rotating cutting tools
- rotating grinding tools usually have a greater thickness in the axial direction. In this way, the axial forces that occur with the side surfaces of the tool during grinding processes are absorbed and in radial processes during grinding processes
- Cutting tool for making gentle cutting cuts, particularly suitable for cutting composite materials with poor thermal conductivity.
- the circumference of the disk-shaped separating tool becomes one
- Cutting gap is produced, which is then widened via convex secondary cutting edges arranged adjacent to the main cutting edge, some of which act radially and some axially.
- the high temperatures that occur during material removal are thereby brought together in both the tool and the workpiece spread out larger area.
- Workpiece material in the area of the cut surfaces, which has undergone temperature-damaging structural changes that damage the material during the production of the cutting gap, is removed during the subsequent expansion of the
- the guide elements do not project axially beyond the cutting width.
- the guide elements can therefore not act in the axial direction, but should be through the

- the display reacts particularly preferably autonomously to mechanical wear of the tool that exceeds a certain dimension, in particular in that another color appears or becomes recognizable.
- the tool takes into account design-related loads such as temperature and tool fatigue that impair the quality of the workpiece.
- the wear indicator now even provides information regarding the process parameters to be selected, such as tool speed and feed speed.
- the invention avoids carrying out the

- the tool according to the invention in particular a cutting-grinding-polishing wheel, preferably has a central bore in the axial direction, for fastening in the usual standardized tool holders of mobile and stationary cutting and
- the feed movement of the tool according to the invention in particular a cutting-grinding-polishing wheel, in the radial working direction for making the cutting cut,
- the tool according to the invention in particular a cutting-grinding-polishing disc, is provided with grinding and polishing agents on at least one side of the disc.
- the grinding and polishing agents are more finely grained or serrated or designed for less material removal than the release agents in order to achieve the intended improvement in the surface quality of the cut surfaces in the axial direction, while at the same time efficient cutting processing in the radial direction.
- the tool according to the invention ensures its usability on account of its combined geometric and kinematic properties and therefore does not have any of the problems and limitations described above. If during the cutting process the tool according to the invention touches the workpiece with its outer circumference in a radial feed movement several specific and specifically used factors for a defined deflection of the disk in both axial
- Cutting gap expansion which is given as an example for this explanation with 10%.
- the cutting gap is therefore 10%
- Cutting gap widening is made possible by certain properties of the disc.
- the operating speed of the cutting disc has a value that is a multiple of one of the natural frequencies of the cutting disc
- the cutting disc is excited to an axial vibration during operation, the amplitude of which is approximately up to 5% of the disc thickness.

- a radial consumption of the tool according to the invention is basically up to
- Tool holder of the operating machine possible. This leads to more efficient use of the tool and enables the use of binding materials that are subject to wear and tear of the abrasive grains responsible for the cutting process. This enables a precise but efficient cut.
- Machine control required, which enables the axial feed of the grinding / polishing elements to the cutting surfaces. Only a radial feed is required from the machine.

- This single-layer grinding layer on the side of the wheel can also be segmented towards the center of the wheel due to a different grain size or simply in a different color. If radial wear then reaches such a specific segment, conclusions can also be drawn about the state of wear. Wear in the radial and axial directions can thus be visualized.
