Definitions

  • the invention relates to a grinding plate with a carrier body with a central connecting hub on one side of the grinding plate and a grinding surface on the other side of the grinding plate and with diamond-containing grinding segments, which are arranged on the casing of the support body and at least on the side facing away from the connecting hub Extend the carrier body, the grinding segments being wider in the circumferential direction of the grinding plate than in the radial direction.
  • a grinding plate of this type is described in AT-PS 378 345.
  • Such grinding plates are used in particular in stone processing.
  • the object of the invention is to develop a sanding plate with which grinding can be carried out in one operation both on the face side and on the casing side. Another object of the invention is to improve such a grinding plate so that higher removal rates can be achieved with it compared to conventional grinding plates.
  • an abrasion ring is provided next to the grinding segments, which is connected to the side of the carrier body facing away from the hub, which is formed by foamed plastic with fillers and which has radially projecting sections between them at a distance from one another arranged grinding segments protrude.
  • the abrasion ring helps to stabilize the tool when grinding at the front.
  • a grinding plate according to the invention produces four times the removal capacity of a conventional grinding plate with roughly comparable roughness values when grinding on the face side.
  • the grinding plate according to the invention can be used as a combination milling cutter, ie it can be used to grind both the front and the casing side.
  • the grinding plate according to the invention can be used as a combination milling cutter, in particular with granite of all wear classes and with concrete.
  • one embodiment of the invention provides that the plastic of the wear ring is polyurethane and that the fillers are at least partially formed by silicon carbide.
  • the carrier body has a cylindrical edge which is surrounded by the abrasion ring. In this way, a good bond between the wear ring and the carrier body is achieved.
  • the abrasion ring is conical on the inside, the abrasion ring being the widest on the end face on the grinding side, and that the carrier body has a central inlet channel for the cooling liquid in the hub area, that this inlet channel is designed as a blind hole, which ends on the grinding side in a cylindrical projection which has at least one radial outlet hole for the cooling liquid.
  • Radially extending through-channels for a coolant are provided in the wear ring.
  • the conical design of the wear ring keeps the coolant in the area of the tool for a long time. This effect can also be improved in that the cylindrical extension is provided at its free end with an outer deflection ring for the cooling liquid.
  • FIGS. 1 and 2 each show a diagram of a grinding plate according to the invention
  • FIG. 3 shows a section through a grinding plate according to the invention
  • FIGS. 4 to 11 schematically show different possible uses of the grinding plate according to the invention.
  • the grinding wheel is marked with S and the workpiece with W.
  • the three essential components of the grinding plate according to the invention are the carrier body 1, the grinding segments 2 and the wear ring 3.
  • the carrier body 1 is plate-shaped and the grinding segments 2 are arranged on its circumference in such a way that they project beyond the carrier body by a dimension a1, a2 on both sides. This is of particular importance for flute grinding.
  • the grinding segments 2 are designed to be relatively narrow, ie their length in the circumferential direction is substantially greater than the width in the radial direction of the grinding plate. When grinding at the end, the cutting ring formed by the cutting segments 2 is therefore relative narrow, which ensures that the outer cutting edge K is always sharp.
  • the abrasion ring 3 adjoins the grinding segments 2.
  • the wear ring 3 is connected to the side of the carrier body 1 facing away from the hub 12.
  • the grinding segments 2 are spaced from one another, so that sections 4 of the wear ring 3 protrude between the grinding segments 2.
  • the inside of the abrasion ring 3 is designed with a conical wall 7.
  • the wear ring 3 is made of foamed plastic, preferably polyurethane with silicon carbide as a filler.
  • the carrier body 1 is provided with a central inlet channel 8 for the cooling liquid.
  • the inlet channel 8 is formed as a blind hole and ends in a cylindrical shoulder 9 of the carrier body 1.
  • the shoulder 9 has a lateral outlet hole 10 for the cooling liquid, which is thereby sprayed radially onto the wear ring 3.
  • the attachment 9 is provided with a deflection ring 11, which contributes to the coolant being in the area of the tool for a long time. This effect is reinforced by the inner cone of the wear ring 3.
  • the grinding plate according to the invention is also suitable for grinding curved edges and for grinding curves inside (FIGS. 8, 9).
  • the foaming between the grinding segments 2, d. H. sections 4 provide damping during grinding, i. H. a chatter-free run is achieved.
  • the grinding plate is provided on the outside with a cylindrical jacket.
  • a conical slip ring could also be provided.
  • the best performance is achieved with the grinding plate according to the invention if it is carried out at a relatively high speed, ie. H. with a peripheral speed of 45 m / sec. is used.
  • a relatively high speed ie. H. with a peripheral speed of 45 m / sec.
  • it is mounted on a grinding machine which has a speed of approx. 10,000 rpm. performs and advantageously has a central water supply through the spindle.
  • FIG. 4 shows schematically a side view of the grinding plate when used in surface grinding.
  • 5 shows the same view for edge grinding.
  • 6 and 7 show side views of the grinding plate for corner grinding.
  • FIGS. 8 and 9 show the grinding plate in plan view when grinding curves and
  • FIGS. 10 and 11 show an end view and a side view of the grinding plate when grooving.
