Definitions

  • the invention relates to a material processing disc for processing material surfaces with the features of the preamble of patent claim 1.
  • material processing discs comprising a base body and an abrasive, which is arranged on the base body.
  • the main body has a central recess for direct or indirect connection of a drive shaft of a tool.
  • material surfaces of objects to be machined can be ground or polished.
  • the removal rate of the known material processing discs is limited. Thus, a rough surface treatment is not possible. Rather, this requires a separate roughing disc, which is associated with high costs and additional effort.
  • the invention is therefore based on the object to provide a material processing disc which is suitable for both a fine and a rough surface treatment.
  • the material processing disc for processing material surfaces comprises a base body with a central recess for connecting a drive shaft of a tool, an abrasive and a roughing agent.
  • the abrasive is disposed on the base body and the roughing means surrounds the base ring.
  • a grinding angle that is, an angle included between the axis of the abrasive article and the material surface of the object to be processed.
  • the base body is a carrier plate, which consists of plastic and / or comprises a mixture of resin and abrasive grain.
  • the roughing agent of the material processing disc according to the invention may have a convex outer surface, which improves the roughing performance of the roughing agent.
  • the base body comprises on its lateral surface a recess into which the roughing means engages. In this way, a firm connection between the main body and the roughing agent can be ensured.
  • the roughing means on the inner surface comprises a circumferential projection corresponding to the recess of the basic body, which extends inwards in the radial direction.
  • the abrasive of the material processing disc according to the invention may be a flap abrasive, which is characterized by a good grinding efficiency and a uniform grinding pattern.
  • the abrasive may include abrasive slats that are glued in particular with an adhesive resin on the body, so that a secure fixation of the abrasive is ensured on the body.
  • the roughing agent comprises a mixture of resin and abrasive grain.
  • step (a.2.3) at least two layers S 1 , S 2 are applied to the first layer S 0 according to step (a.2.2), so that an at least three-layered stack is formed .
  • step (a.2.2) at least two layers S 1 , S 2 are applied to the first layer S 0 according to step (a.2.2), so that an at least three-layered stack is formed .
  • steps (a.2.2) and (a.2.3) layers S 0 and S 0 + u are applied, each having the radius r m, n , wherein the radius r m , n of the layer S 0 to S 0 + u and the layers S no to S n is greater than the radius r m, n of the layers S 0 + u + 1 to S n-0-1 and n - u - o ⁇ 1, so that on the base body a recess and on the roughing means a projection is formed.
  • the roughing agent may be manufactured in step (a) to include a concave outer surface, thereby improving roughing performance.
  • the abrasive lamellae are glued or fixed on the abrasive side of the main body in step (b), for example, with an adhesive resin or fixed thereto, wherein adhesive resins have particularly good adhesive properties.
  • Fig. 1 shows a material processing disc 10 according to the invention with a base body 20, an abrasive 30 and a roughing agent 40th
  • the main body 20 is disk-shaped and has a central recess 21 with a radius r i for connecting a drive shaft of a tool.
  • the roughing means 40 surrounds the main body 20 in an annular manner, wherein a lateral surface 22 of the main body 20 is in contact with an inner surface 41 of the roughing means 40.
  • the roughing means 40 comprises on an inner surface 41 a projection 42 corresponding to the recess 23 of the main body 20 and has a convex outer surface 43 with respect to an object 50 to be machined, ie in cross-section, the outer surface 43 of the roughing means 40 is arched outwardly.
  • the main body 20 and the roughing means 40 enclosing the main body 20 may comprise (n + 1) layers S 0 to S n .
  • the (n + 1) layers S 0 to S n each include a disc-shaped base layer and a disc-shaped roughing agent layer each formed of a mixture of resin and abrasive grain.
  • the base body layers each have an inner radius r i , which corresponds to the radius of the recess 21 of the base body, and an outer radius r m, n .
  • An inner radius r m, n of the roughing agent layer corresponds to the outer radius r m, n of the base body layer.
  • the base body may consist of a suitable plastic.
  • an abrasive 30 is arranged on an object 50 to be machined facing side or grinding side 24 of the base body 20 on an object 50 to be machined facing side or grinding side 24 of the base body 20, an abrasive 30 is arranged.
  • the abrasive 30 comprises abrasive fins 31 adhered to the abrasive side 24 of the base 20 with an adhesive resin.
  • the material processing disk 10 has an axis of rotation 11.
  • a surface of the grinding wheel 10 which is in contact with the surface 51 of the object 50 to be machined can be changed.
  • the surface 51 can be processed with the roughing agent 40. If the angle SW is large, in particular, close to or equal to 90 degrees, the surface 51 to be processed is in contact with the abrasive 30.
