Definitions

  • the present invention relates to a method and a processing device for surface processing, in particular for grinding and / or polishing, of workpieces, in particular for the surface treatment of implants or of implant parts.
  • the grinding or polishing effect is based on the fact that the moving ("dragged") workpieces in the bed of the surface treatment agent are a displacement or cause soft movement of the particles of the surface treatment agent, so that adjacent to a workpiece, relative to this moving particles have an abrasive effect.
  • some resistance to movement of the workpieces in the surface treatment agent is required. It was found that the abrasion formed in the surface treatment increases the resistance to movement over time and the abrasion must be removed from the bed. An attempt was made to stimulate the treatment container to vibrate, but this caused an uncontrollable decrease in movement resistance and treatment outcomes. For this reason, so far the treatment process of the workpieces to remove the abrasion had to be interrupted.
  • the present invention is based on the so-called drag dragging technique known as known, the invention being based on the object of further developing the method and the device, so that in particular the disadvantages described above are avoided as far as possible can be.

In particular, under the action of external forces, in particular directed forces or pressure on the powder, reversible and therefore temporary lumping or clumping occurs. A compression caused by external pressure or external forces is thus associated with a restriction or possibly even with a loss of flowability; in particular cohesive forces between the powder constituents can be responsible for this.
  • reversible baking means that the powders proposed according to the invention, on the other hand, have the property that the baking can be completely or at least partially eliminated by vibration or suitable vibrations, ie a loosening and "caking" is possible, according to one certain flowability (also depending on the nature and extent of the vibrations) can be completely or at least partially restored.

Such powders have hitherto not been used in drag grinding since baking undesirably occurs along the repeating trajectory of the workpieces for furrow formation in the surface treatment medium.
  • the Applicant has surprisingly found in experiments that the tendency to form bridges or to caking certain powders during drag grinding can even be advantageously utilized in a targeted manner, since limited caking of the powdery surface treatment agent leads to a likewise only limited increase in pressure at the surface the workpieces leads, so in addition to a friction effect, an increased pressure effect occurs and ultimately a more uniform and better surface treatment is possible.
