Definitions

  • the invention relates to a grinding wheel according to the preamble of claim 1.
  • the stones may in particular be artificial stones, such as bricks, which, after their manufacture, are attached to their surface, e.g. may have ridges derived from cutting operations, which are the subsequent processing in the way and therefore to be machined.
  • the cutting wheel has a cutting means in its peripheral region, which has a working surface on a working side of a disk-shaped wheel body of the grinding wheel and is effective on this working side of the grinding wheel and accessible to the object to be machined.
  • the grinding wheel is rotated by a rotary drive, wherein the abrasive rotates in a ring zone.
  • this or these are moved on a conveyor track on the working side of the grinding wheel over so that they come into contact with the abrasive and machined.
  • This machining operation may be a grinding or milling operation.
  • grinding is used because this name is at least introduced in the brick industry.
  • a cutting wheel which represents a total of a top and bottom open frusto-conical structure whose inner circumferential surface is connected via six Verstrebungssegmente with a central hollow shaft, so that the Truncated cone - even after applying the hollow shaft to a vertical drive shaft - is open up and down.
  • the cutting parts or the polishing plates are mounted on the lower end face of the truncated cone, whereby the workpiece can be processed horizontally.
  • the Verstrebungssegmente In order to generate an air flow through the interior of the cutting wheel, so as to cool the workpiece during processing and to remove the cutting, milling or abrasion dust, the Verstrebungssegmente an equal inclination, resulting in a strong rotational movement of the cutting wheel to a ship screw-shaped suction or blowing of the workpiece with the ambient air leads.
  • a cutting device in which the cutting wheel is covered with a disc on the back and only between the disc edge and the abrasive segments has a gap (air gap).
  • the air gap can be supplied with a sufficient quantity of air which, on leaving the air gap, cools the abrasive segments and keeps them free from abrasion and grinding dust.
  • a grinding wheel which is designed as an impeller of a centrifugal pump in that a coolant is pressed circumferentially on the entire wheel width through a porous or cannulated grinding wheel.
  • the coolant is supplied, for example, the impeller by the shaft over which the impeller is pushed.
  • a grinding wheel for use in a grinding apparatus having dust removing drive vanes for reducing the distribution of dust in the air, and for increasing the cooling effect of the grinding wheel to improve the grinding ability and extend the life of the grinding wheel.
  • a cutting wheel of the type specified is in the DE 101 62 425 A1 described.
  • This prior art grinding wheel has a radially outwardly extending from a bearing assembly wheel body on the working side, a disc-shaped cover body with axial distance to the wheel body is mounted, wherein arranged between the wheel body and the cover body Conveying elements suck in air through a hollow shaft of the bearing assembly from the side facing away from the working side of the grinding wheel ago and promote outward to the abrasive out.
  • an air supply duct extends through a motor shaft designed as a hollow shaft. Due to the considerably long hollow shaft and due to a desired small construction not only a relatively small air supply cross section is available, but the air supply is relatively low due to the considerable length of the hollow shaft resulting line losses.
