Definitions

  • the invention relates to a polishing disc or polishing roller of the type specified in the preamble of claim 1.
  • Polishing disks or rollers of this type are intended for use in polishing or buffing machines, in which they are made to rotate rapidly for polishing, polishing, lapping or clarifying the surface of prepared workpieces and provided with a polishing or clarifying agent on their free peripheral surface.
  • the compliant layer has so far mainly consisted of completely round sheets of fabric, which are either loose or quilted together.
  • the finest fabrics made of wool or cotton are mainly used, which should adapt to the contours of the workpiece to be machined as well as possible.
  • the invention is therefore based on the object of providing a polishing disc or roller which has a cloud or
  • the invention is based on the idea that cloud-free clarification of even complicated surfaces is only possible if the grain contained in the clarifying paste is hammered in evenly into the deepest corners of the workpiece surface, that is to say if there is a constant level of fogging, which can be controlled via the speed is maintained without local pressure.
  • this is achieved in that the individual threads do not hit the surface of the workpiece with a whip like length, and are pulled off over the disc as the disc continues to rotate. They avoid a pressure axially, so that the press values cannot add up, as is the case with polishing discs made of fabric sheets.
  • the heat development during the polishing process is also much lower than before, so that threads with a component of synthetic fibers can be used, which ensure a long service life.
  • the proportion of particle-repellent synthetic fibers for example polyester fibers, can increase steadily in the axial direction from one side of the pane to the other.
  • the workpiece surface can first be freed of coarse bumps and impurities by simply pushing it in the axial direction and brought to a high gloss with an increasing proportion of synthetic fibers in the threads.
  • the individual threads that are driven outwards due to the centrifugal force are 30 to 50 cm long and 0.02 to 1 mm thick and result in a thread density of 10 to 100 threads per cm 2 on the peripheral surface.
  • the polishing disk can be provided at its front ends with limiting rings made of textile material, which can be separated by radial cuts into individual, overlapping strips of fabric.
  • the limiting rings also have the task of stabilizing the air flow in the area of the polishing pad and of keeping the axial spreading of the thread layer within limits.
  • the polishing discs shown in the drawing consist of a rigid support ring 10 and a resilient layer 12 fastened to the circumference of the support ring, which layer contains a multiplicity of individual threads 14 arranged distributed over the circumference of the support ring.
  • the individual threads With a rapidly rotating polishing disc, the individual threads are under the influence of centrifugal force so that their free ends point essentially radially outwards.
  • the individual threads 14 are formed to form thread layers (not shown) with a thickness of approximately 10 mm a spiral or ring-shaped bandage 15 connected to each other.
  • these thread layers are attached to the support ring surface at a mutual axial distance of about 20 mm, for example glued or quilted.
  • the thread ring-side thread ends are wound onto the support ring surface in the circumferential direction before they are fixed there.
  • the at least 10, preferably 30 to 50 mm long, free thread ends are driven outwards by the centrifugal force in such a way that, despite the thread layers arranged at a distance from one another, they have a peripheral surface 16 with an approximately uniform thread density of approximately 10 to 100 threads per cm.
  • the twisted individual threads 14 have a diameter of approximately 0.02 to 1 mm and, after prolonged use, are spread apart like a brush at their free ends.
  • the polishing disc is provided at its front ends with limiting rings 18 made of textile material, which are separated by radial cuts 20 into individual, overlapping strips of material 22.
