Definitions
- the invention relates to a grinding wheel with a carrier wheel and one on the circumference the abrasive layer arranged thereon, the abrasive layer covering a large number has the circumference of distributed recesses, which in a radial view of the The circumference of the grinding wheel is cup-shaped or scoop-shaped.
- Grinding disks are already known, in which on a carrier disk Segments provided with abrasive grain distributed over the circumference, for example are glued on. It is also already known to circumfer these segments To be spaced from each other and in the formed between the segments Feed recesses of liquid coolant and / or lubricant. In particular it is known from DE 38 04 781 A1, the recesses between the segments To be V-shaped.
- the object of the invention is to improve the known grinding wheels, in particular with regard to improved grinding properties and greater stability.
- the recesses according to the invention are cup-shaped or scoop-shaped and limited on both sides, so that the cooling and / or Lubricant is held in the transverse direction and therefore better in the grinding zone lingers.
- V-shaped or U-shaped recesses allow one more additional effect, namely the guiding of coolant and / or lubricant from the peripheral edge the grinding wheel towards the center (i.e. towards the arrowhead of the V or towards the Vertex of the U).
- V's and U's can also be lined up and overall, for example, give a serrated shape of the recesses. It is coming thus to a hydrodynamic pressure build-up.
- Such grinding wheels with V or U-shaped recesses that are distributed over the circumference are general direction of rotation, d. H. the desired effect can only be achieved with one direction of rotation achieve, namely the one in which the V or U is moved forward open.
- a carrier or a carrier disc 1 for example made of steel, ceramic, damping carrier body, CF carrier body
- the abrasive grain (abrasive) and the type of binding are arbitrary in themselves.
- Corundum, CBN (Cubic boron nitride) suitable abrasives for example come as bonds Ceramic, synthetic resin or metal in question.
- the separate grinding segments are arrow-shaped, so that between give them V-shaped recesses 3, which are shown in black in Fig. 1 are. These V-shaped recesses are in a radial view of the circumference the grinding wheel is cup-shaped or scoop-shaped and laterally obscenely closed.
- FIG. 3 which is not tied to the direction of rotation are the grinding segments 2 angled at right angles twice in the plan view and so close together that no opening to the side of the grinding wheel exists, so essentially cup-shaped recesses 3 are formed.
- the grinding segments 2 angled at right angles twice in the plan view and so close together that no opening to the side of the grinding wheel exists, so essentially cup-shaped recesses 3 are formed.
- the laterally closed, cup-shaped recesses are sufficient for one To achieve improvement over conventional grinding wheels, where the Recesses to the side are completely open.
- FIG. 4 shows a highly schematized grinding wheel according to the invention and a Device 5 for the supply of coolant and / or lubricant in essentially tangential direction just above the contact area with the workpiece 6. According to the invention, not only can it run in the same direction but also in the opposite direction grind.
- cooling and / or Lubricant via radial channels 7 to the outside in the area of the recesses 3 to lead (see Fig. 5).
- Coolant and / or Lubricant supply can be combined with one another as desired.
- each recess extends here 3 in depth down to the carrier disc 1.
- Recess area 3a is available as a cup-shaped or scoop-shaped area stands: Instead of thicker grinding segments, one can also be preferred on the carrier single-layer thin layer of abrasive grain.
- the recesses can then mainly extend in depth in the carrier.
- FIG. 7a and 7b show further exemplary embodiments for the arrangement of the recesses 3.
- Fig. 7a alternate U-shaped and V-shaped recesses.
- 7b shows V-shaped recesses 3 distributed over the peripheral surfaces.
- the invention is not restricted to the exemplary embodiments shown.
- the shape of the segments or the recesses formed between them can vary, for example, a serrated shape of the recesses is possible.
- the length and the Dimensioning of the segments or the recesses can be the respective Grinding requirements are adjusted. Basically, it is also possible to get one to use continuous abrasive layer in which the recesses are formed are. In practice, however, the structure of a large number is directly lined up Segments expected to be cheaper. The concept of the grinding wheel can be seen widely and also includes dressing tools.
