Definitions
- the invention relates to a grinding wheel according to the preamble of the claim 1.
- grinding wheels provided with diamond-containing cutting bodies and a conditional suitability for the treatment of coated, mineral substrates exhibit.
- the primary use of these grinding wheels is for mineral Substrates designed. From US 3,745,719 is such a grinding wheel with a circular grinding area, a central receiving area, a plurality of passage openings in the grinding area and several protruding from the grinding area, one rectangular base having cutting bodies in different radial Distances from the center of the receiving area are arranged, known.
- the invention is based on the object, an economically producible grinding wheel to create, with their cutting body, the coating of the substrate wedge-shaped can be cut and each cutting body a self-sharpening, sharp-edged cutting edge has.
- the cutting body is a wedge-shaped Cutting the ablated coating achieved.
- the wedge-shaped penetration of the Cutting body into the coating leads to a rapid removal of the same from the surface on which this adheres, without being heated and without that worn coating material sticks to the cutting bodies.
- a special High removal rate is achieved when the angle between the center of the receiving area facing longitudinal side of the cutting body and the radial 45 ° is.
- the good penetration of the cutting body in the coating leads to a smooth running in grinding operation.
- Each cutting body preferably has two matrix zones with different ones Diamond concentration, which in a parallel to the broad side of the cutting body extending Direction are arranged one behind the other. That matrix zone with the higher one Diamond concentration serves to remove the coating and the matrix zone with the Lower diamond concentration has the function of a support back.
- the removal of the coating done with a sharp-edged cutting edge can, which extends over the center of the receiving area facing longitudinal side of the cutter body and extends at the free end of the cutter body, conveniently has the closer to the center of the receiving area
- the first matrix zone has a higher diamond concentration than the center of the Receiving area facing away second matrix zone.
- the diamonds in the first matrix zone have a smaller grain size as the diamonds in the second matrix zone.
- the Diamonds are not as fast as in the second matrix zone.
- Even if the Diamonds break out in the first matrix zone, leading them due to their very small size Do not scale to a blurred cutting edge.
- Due to the larger grain size the diamonds in the second matrix zone break out faster than the diamonds in the first matrix zone.
- the second matrix zone thus allows greater wear of the back support, which forms in the grinding operation and thus the cutting edge of the Cutting body to a certain "exemption" helps.
- the parallel to the broad side of the cutting body corresponds measured width of the matrix zone with the higher diamond concentration of 0.15 bis 0.35 times the width of the cutting body.
- the grinding area is advantageously arranged in a plurality of radially offset from each other, at least partially radially overlapping coaxial with each other Divided annular surfaces, wherein in each annular surface at least one cutting body is arranged.
- An increase in the removal rate of the grinding wheel is preferably characterized ensures that each cutting body is arranged inclined relative to the disk plane.
- the inclined arrangement of the cutting body helps to remove the coating in that the coating material does not lie on a vertical surface during removal but meets an inclined surface of the cutting body and of this under one Angle - the so-called rake angle - is deflected from the ground.
- the inclined surface is the one facing the center of the receiving area Longitudinal side of the cutting body, which at an angle of 80 ° to 90 ° to a is arranged from the grinding area formed disc plane.
- This 80 ° to 90 ° give a rake angle of 10 ° to 20 °, which is between said longitudinal side and a projecting from the disk plane perpendicular.
- a good removal of the removed coating material from the processing area takes place by a plurality of passage openings arranged in the grinding area of the grinding wheel, expediently in an edge region opposite the edge Each cutting body is arranged a passage opening.
- the grinding wheel shown in FIGS. 1 to 3 serves for the removal of applied to mineral substrate coatings. Neither the coating yet the mineral substrate are shown in Figs. 1 to 3.
- the grinding wheel has a central receiving area 2, several Passage openings 3 in the grinding area 1 and several protruding from the grinding area 1, a rectangular base having cutting body 4.
- the grinding area 1 and the central receiving area 2 are arranged coaxially with each other, but in a parallel spaced from one another to the common central axis direction.
- the Transition 10 between the central receiving area 2 and the grinding area 1 is conical and provided with a plurality of through holes 9.
- the grinding area 1 is composed of a plurality of radially offset from each other, at least partially radially overlapping, coaxially extending annular surfaces D, E, F together, wherein in each annular surface D, E, F four or eight Cutting body 4 are arranged evenly distributed.
- the cutting body 4 thus have different distances from the central receiving area 2.
- Eight cutting body 4 are located in the farthest from the center of the reception area Circular ring surface D arranged. Of the three annular surfaces D, E and F overlap in the radial direction only the annular surfaces E and F.
- each cutter body 4 is at an angle B of 45 ° to one from the center of the receiving area 2 outgoing Radial R arranged.
- the radial runs through the Intersection point S between the center of the receiving area 2 facing Long side 5 and facing away from the center of the receiving area 2 wide side. 6 of the cutting body 4.
- Each cutting body 4 has two matrix zones 7, 8 with different Diamond concentration on, in a parallel to the broad side 6 of the cutter body 4 extending direction are arranged one behind the other.
- a the center of Receiving area 2 closer matrix zone 7 has a higher diamond concentration on as a remote from the center of the receiving area 2 second matrix zone 8.
- the diamonds of the individual matrix zones 7, 8 have different Grain sizes.
- all diamonds are in the first matrix zone 7 is a smaller grain size than the diamonds in the second matrix zone 8.
- the parallel to the broad side 6 of the cutting body 4 measured width of the matrix zone 7 with the higher diamond concentration corresponds to 0.25 times the width of the cutting bodies 4.
- Each cutter 4 is inclined relative to the disk plane, wherein the the center of the receiving area 2 facing longitudinal side 5 of the cutting body. 4 is arranged at an angle A of 85 ° to the receiving area 2.
- the central receiving area facing longitudinal side 5 and the center of the facing broadside 6 together form an edge (K).
- a passage opening 3 In one of the edge K opposite circumferential region of each cutting body 4 is a passage opening 3, through which the abraded coating material, for example with a Suction device, not shown, can be sucked off.
