Definitions
- the present invention relates to a honing tool with an abrasive and a binding agent, the honing tool having two or more layers which are cut from the grinding surface.
- Honing tools are used, among other things, to manufacture and machine precision gears and worms, especially for straight and helical gears. Honing tools are generally known in the prior art.
- EP 0 692 342 shows a toothed honing tool in which ceramic fine grains are embedded in a synthetic resin matrix. Ceramic corundum abrasives are also known from EP 0 622 483.
- honing tools With honing tools, a long service life, high stock removal and a short honing time per workpiece are of particular interest. In addition, accuracies down to a range of 10000 millimeters (for example in motor vehicle transmissions) are expected for power honing. Improved profile retention is also important. Overall, a reduction in process costs should be aimed for. These criteria are not or only partially met by honing tools in the prior art.
- the object of the invention is therefore to create a honing tool which achieves significant improvements over the prior art in the sense of the above-mentioned criteria.
- the binder of the layers is different from at least two adjacent layers, at least these two layers containing abrasives.
- This layered structure of the honing tool ensures that the service life of the honing tool is significantly increased compared to known power honing tools and that the honing time per workpiece is significantly reduced. Furthermore, a profile shape retention is achieved, which is significantly improved compared to the prior art. Another advantage is the reduced process costs in the manufacture of the honing tool according to the invention.
- a preferred embodiment provides that the layers of the honing tool have a constant thickness.
- Another preferred embodiment provides that the layers alternately have ceramic and plastic as the respective binder of the layers.
- the layers of the honing tool are continuous in the direction of the layering. On the one hand this increases the stability, on the other hand there is no change in the grinding behavior even after prolonged use of the honing tool according to the invention.
- the layer boundaries are essentially perpendicular to the grinding surface. This also helps to ensure that the grinding behavior of the honing tool does not change even during long-term use.
- a favorable variant is that the layers have a disk shape, the individual disks lying against one another.
- a preferred embodiment of a honing tool which has a longitudinal axis, provides for the grinding surface to be in the form of a negative impression of the workpiece to be ground, the grinding surface along the longitudinal axis only having grinding surfaces lying essentially parallel to it.
- the grinding surface can thus be adapted to the shape of the workpiece to be ground both on the outer and on the inner surface of the layer honing tool.
- the honing tool can be used for honing, for example, gears with external teeth.
- the honing tool generally performs a linear back and forth movement along a longitudinal axis during honing, it is particularly advantageous that the grinding surface along the longitudinal axis only has grinding surfaces lying essentially parallel to it. Due to the linear back and forth movement of the honing tool during the grinding process, the cross-sectional shape can in principle be perpendicular to the longitudinal axis of the Honing tool can be adapted to almost any shape of the workpiece (for example, rectangular or oval cross-section), as long as the shape of the workpiece or the grinding surface of the honing tool is constant along the longitudinal axis. It is particularly advantageous here that the layer boundaries are perpendicular to the longitudinal axis.
- a particularly preferred embodiment provides that the outermost layers of the honing tool each have synthetic resin as a binder. This is reflected in a particularly good grinding behavior of the honing tool, while the ceramic matrix used in the inner layers alternately with a synthetic resin matrix guarantees a higher stability of the honing tool according to the invention.
- abrasives it is particularly favorable that preferably all layers have abrasives.
- all common abrasives such as Corundum, silicon carbide, diamond, borozone - preferably noble corundum and their mixture - can be used.
- the selection of the respective abrasive depends on the task and can be adapted to it.
- a variant which is particularly preferred in terms of construction provides that the honing tool is hardened.
- Fig. 1 shows a section perpendicular to the layers of the invention
- Fig. 2 is a perspective view of the grinding surface of a blank of the
- FIG. 3 shows an embodiment according to the invention for honing gears with external teeth
- Fig. 4 shows an embodiment of the invention for honing gears with internal teeth.
- continuous layers are alternately built up with a matrix of synthetic resin 1 and a matrix of ceramic 2, the respective outer layer 3 consisting of synthetic resin.
- the thickness 4 of the individual layers can be different, but this is generally between 0.5 and 50 mm.
- the honing tool is manufactured by alternately pressing layers with a synthetic resin matrix with fired layers with a ceramic matrix using the hot press method (pressing or hardening temperature 60 to 250 ° C). If necessary, hardening (fire) is carried out at elevated temperature after the pressing process.
- the binder contained in the synthetic resin disc is infiltrated into the ceramic disc and thereby creates a connection between the discs. No further addition in the form of a binder is therefore required for the connection of the panes.
- the materials used in the ceramic layers correspond to the material structure and in production to the process of producing a standard ceramic grinding wheel including firing. All common abrasives such as corundum, silicon carbide, diamond, borozone - preferably noble corundum and their mixture - can be used.
- the grain size used is between 30 and 1000 mesh.
- the density of the ceramic layer is between 1 and 3 g / cm 3 .
- a blank shown in FIG. 2 is manufactured as described above, it is adapted to the shape of the workpiece to be honed. This is done using suitable processing tools, e.g. made of diamond. Since the finished honing tool is usually linear along its longitudinal axis during honing 6 is moved back and forth, its grinding surface 5 can be adapted to almost all shapes of the workpiece to be machined.
- suitable processing tools e.g. made of diamond. Since the finished honing tool is usually linear along its longitudinal axis during honing 6 is moved back and forth, its grinding surface 5 can be adapted to almost all shapes of the workpiece to be machined.
- Fig. 3 shows an embodiment in which the layer honing tool for machining gearwheels with external teeth has been manufactured.
- the internal teeth 7 as part of the grinding surface 5 of the layer honing tool have a negative shape of the teeth of the workpiece to be machined, not shown.
- the layer structure and the layer sequence of layers 1, 2, 3 corresponds to that of the blank shown in FIG. 2.
- Fig. 4 shows an embodiment of a layer honing tool, which has been manufactured for the machining of gears with internal teeth.
- the teeth 8 must be part of the grinding surface 5 of the layer honing tool on the outer surface of the layer honing tool.
- the layer structure in turn corresponds to that of the blank shown in FIG. 2. It should be emphasized here in particular that both in FIG. 3 and in FIG. 4 the layers have continuously parallel layer interfaces which are perpendicular to the longitudinal axis 6.
- it is fundamentally possible to adapt a blank to almost any cross-sectional area of the workpiece to be machined e.g.
- the layer honing tool since the layer honing tool generally only has one during operation performs linear reciprocation along the longitudinal axis 6. However, it is important here that the grinding surface 5 of the layer honing tool along the longitudinal axis 6 only has grinding surfaces lying essentially parallel to the longitudinal axis.
