Definitions

  • the invention relates to methods and devices for a machining of workpieces with a tool, in particular drilling and / or milling of workpieces made of wood or wood substitutes, such as fiberboard, and, where appropriate, also of plastics.
  • Drilling and / or milling belong to the classic machining of workpieces. Nevertheless, there is a fundamental difference between the processing of metal and wood or wood substitutes, possibly also plastics. Even if the tools are being machined with relatively low cutting speeds when machining metal workpieces, the tools nevertheless have to be cooled regularly.
  • a simple form of cooling is the introduction of a cooling liquid to the processing point from the outside.
  • drills it is known in particular with drills to provide them with axially extending cooling channels through which a cooling liquid flows and which usually exits at the processing point from the tool.
  • the invention has the object to provide methods and apparatus for a D cutting machining available through which the workpiece after machining is largely free of chips and provided with functional grooves, holes or the like.
  • Tool lifted chips is cleaned.
  • grooves and drilled holes can be cleaned without any problems and are immediately available after processing.
  • compressed air can be used as the gaseous rinsing agent, which is regularly available on a regular basis both in the required quantity and under sufficient pressure for corresponding machine tools for the treatment of wood or wood substitutes.
  • the chips blown away from the processing point do not deposit on the surface of the workpiece, it can be provided in a further embodiment of the method according to the invention that the chips removed from the workpiece by blowing are caught and sucked off in a suction box covering the processing point (s) ,
  • a suction box can be designed small volume and accordingly reduces the suction power.
  • a drilling gear for driving at least one receptacle for a clamping shaft of a tool according to claim 4 wherein the receptacle has an opening, the aperture corresponds to an inlet opening of the channel in the clamping shaft of the tool and the opening with a pressurized, gaseous rinsing agent is acted upon.
  • each receptacle is then provided with an opening and the apertures are connected to a manifold.
  • an opening is arranged axially extending in a receptacle, more preferably on a rotation axis of the receptacle.
  • the machining point (s) of the workpiece is enclosed by a suction box and that the suction box covers a gap between the workpiece and a receptacle (s) of the drilling gear.
  • the exit of the gaseous rinsing agent from the channel takes place directly at the processing point, so that chips are safely removed in the immediate vicinity.
  • the tip has two central recesses connecting a central spike and two radially outer prongs and that the blades are each provided with an outlet opening of a channel. It is further preferred that a normal on the surface of the inlet opening and / or the outlet opening is axially aligned, whereby a vertical blowing of the processing point takes place.

Abstract

L'invention concerne un procédé pour l'usinage de pièces (23) par enlèvement de copeaux à l'aide d'un outil (forets 5-7). Selon ce procédé, on fait passer un fluide de lavage gazeux à travers au moins un conduit traversant (24, 25) de l'outil (forets 5-7) lors de l'insertion de l'outil (forets 5-7) dans la pièce (23) et on élimine les copeaux enlevés par l'outil (forets 5-7) du point d'usinage (26) de la pièce (23) par expulsion à l'aide du fluide de lavage.
