Definitions

  • the invention relates to a polishing device for polishing an object to be polished and a polishing method for polishing an object to be polished.
  • Grinding is a cutting, material-removing manufacturing process for changing surfaces or separating material parts using abrasives and bonded cutting grain.
  • DE 20 2012 100 088 U1 discloses a carrier plate for flap grinding disks with a dome-shaped inner part, on which a hub is designed for attachment to a shaft of a drive machine, and with an outer flange used to fix grinding flaps, which is connected to the dome-shaped inner part via a conical ring formed thereon, in which opening slots distributed over the circumference for the passage of air or for removing abrasion are incorporated, which run obliquely to the radial direction, with air deflection vanes being formed on the inside of the conical ring between the opening slots.
  • Polishing is a smoothing, finishing process for a wide variety of materials. Roughness peaks in the surface structure are deformed and thus leveled. However, there is no or at most minimal material removal, so that polishing is at least essentially abrasion-free.
  • the surface is leveled and smoothed with extremely fine polishing agent, which is bound in a paste or liquid, for example.
  • the polishing agent is, for example, bound in a cloth, felt, rubber, pitch or leather disc or is applied superficially. The actual polishing process therefore does not take place on the polishing body (particularly made of felt), but rather on the polishing agent provided on it or in it.
  • polishing refers to a decorative surface treatment without or without significant material removal for the purpose of refining the polished surface.
  • EP 1,313,594 B1 discloses a polishing tool for rotating drive by a machine tool, with a solid, ie not hollow (i.e. without cavities or holes), polishing body essentially made of a felt, the polishing body being divided into many areas.
  • DE 39 10 590 A1 discloses a cold gas processing device for polishing.
  • a compressed air vane motor is equipped with an angle head, to the drive shaft of which a polishing plate with a lambskin hood is attached. It is fastened by a nut that rests on the needle.
  • the cold gas is supplied using compressed air via a hose and the angle head into the hollow shaft. From there, the cold gas passes through holes into the working zone of the polishing wheel. By constantly pumping gas out of the work zone and replacing it with new cold gas, the polishing wheel is permanently cooled without prior cooling of the workpiece.
  • the polishing roller comprises a hollow cylindrical body, which is closed at its ends by shaft ends and contains a plurality of bores on its circumference, which establish a connection between the interior of the hollow cylindrical body and the outside.
  • An axial hollow bore in the shaft end is connected to the interior of a sleeve via radial bores.
  • the sleeve is provided with a connecting piece through which compressed air is supplied in the direction of an arrow by means of a compressed air blower. Cooling air is blown between individual polishing rings in a radial direction outwards and thus onto the rotating workpiece.
  • polishing errors occur on the surface of an object to be polished, particularly during prolonged operation of a polishing device.
  • so-called fish eyes can undesirably occur as local depressions on the surface of an object to be polished as polishing defects in conventional polishing devices.
  • a polishing device for polishing an object to be polished having a rotatable (in particular a rotatably mountable or rotatably mounted) carrier body, a polishing body attached or attachable to the carrier body (possibly comprising a polishing agent) for polishing the object to be polished, when the polishing body rotates with the carrier body and acts on the object to be polished, and has a heat dissipation device provided on the carrier body (in particular a heat dissipation device mounted thereon or integrated therein in one piece) for dissipating heat from the polishing body and / or the object to be polished, if the polishing body rotates with the carrier body and the polishing body polishes the object to be polished.
  • a polishing method for polishing an object to be polished wherein in the polishing method a rotatable carrier body is driven in rotation, the object to be polished is polished by means of a polishing body attached to the carrier body and rotating with the rotatably driven carrier body, and (in particular as a result of the polishing process) Heat is dissipated from the polishing body and/or the object to be polished by means of a heat dissipation device provided on the carrier body when the polishing body rotates with the carrier body and the polishing body polishes the object to be polished.
  • a polishing device is created in which, during the polishing process, the frictional heat generated by the interaction between the polishing body and the object to be polished is dissipated by a heat dissipation device provided on the carrier body itself.
  • the heat dissipation device is activated or operated synergistically by the rotation process of the carrier body. In other words, the heat dissipation is triggered by generating an air flow by rotating the carrier body including the heat dissipation device. This means that the drive energy of the polishing device can be used simultaneously to dissipate heat.
  • polishing errors such as the undesirable formation of polishing marks such as fish eyes
  • polishing defects can be promoted by polishing at temperatures that are too high.
  • Such overheating of the polishing body and/or the object to be polished can be efficiently suppressed by means of the heat dissipation device provided on the carrier body.

  • projections on the ventilation channels for example cooling fins to reinforce a fan effect
  • These projections clearly serve as air vanes or paddle wheels, which specifically introduce ambient air into the ventilation channels in order to increase the air flow as a coolant fluid in the direction of the polishing body and/or the object to be polished.
