Definitions

  • the invention relates to a method for deburring the Cutting edges of a cutting tool.
  • a device for deburring the cutting edges of a cutting tool having an axis of rotation is also a device for deburring the cutting edges of a cutting tool having an axis of rotation.
  • the invention is therefore based on the object of a method of the type mentioned at the beginning with which the Cutting edges in a gentle way without damage or rounding can be deburred.
  • Another object of the invention is to provide a Device for deburring the cutting edges of an axis of rotation having cutting tool, such as one Router, a drill or a tap.
  • the task of being under high pressure by at least at least one nozzle directed liquid in the mold a liquid jet with one for cutting off the burrs sufficiently high speed on the cutting edges is directed.
  • the fluid pressure or the speed at which the Liquid jet hits the cutting tool directs depending on the material from which the cutting tool is made is made.
  • the cutting area is within the pressure range between about 50 and 1000 bar, whereby for most Materials such as Titanium 200 to 400 bar are sufficient.
  • One for deburring cutting tools with an axis of rotation suitable device comprises a clamping means for the temporary Clamping the cutting tool to be deburred and at least one arranged transversely to the axis of rotation and liquid-carrying directed towards the cutting tool Nozzle, the nozzles and / or the clamping means for Set up a rotary movement around the axis of rotation are.
  • a plurality of nozzles are preferably annular and preferred axially symmetrical with respect to the axis of rotation arranged.
  • the nozzles can all be in the same plane or be arranged on several levels. With an arrangement on several levels there may be an additional shortening the machining time when deburring.
  • At a particularly useful nozzle arrangement are the individual nozzles on the inner circumference of a liquid-carrying Ring.
  • 1 and 2 comprises a deburring device 10 for deburring the cutting edges 14 of a rotation axis z cutting tool 12, e.g. a tap made of titanium, a clamping head 16 for temporary Inclusion of the cutting tool 12 and an annular Spray device 18.
  • a deburring device 10 for deburring the cutting edges 14 of a rotation axis z cutting tool 12, e.g. a tap made of titanium, a clamping head 16 for temporary Inclusion of the cutting tool 12 and an annular Spray device 18.
  • the cutting tool 12 is in the clamping head via a shaft 13 16 clamped and can be rotated by a Clamping head around the axis of rotation z in a rotary movement be transferred.
  • the coaxial to the axis of rotation z Spray device 18 has an annular arrangement Channel 20, which is connected to a liquid via a high-pressure pump 22, preferably with water.
  • the pressure in channel 20, for example, to a value between 200 and set to 400 bar.
  • nozzles 26 From the inner wall 24 of the annular spray device 18 protrude nozzles 26.
  • the nozzles 26 connected to the channel 20 are on the axis of rotation z or on the cutting tool 12 directed and lie in a common plane E.
  • Pump 22 emerges from nozzles 26 at high speed a jet of liquid 28.
  • the water pressure and the inside diameter of the nozzles is preferred adjusted so that the liquid jet 28 is a laminar Shows flow behavior.
  • the clamping head 16 with the cutting tool 12 is around the Axis z set in rotation.
  • the ring-shaped spray device 18 is in the direction of the axis of rotation z between two End positions moved back and forth. The two end positions are selected so that the liquid jets 28 cover the entire Cover the length of the cutting edges 14.
  • liquid jets emerge from the nozzles 26 28 out and hit the Cutting tool 12.
  • the spray device 18 By oscillating movement of the spray device 18, for example with a frequency of 0.5 Hz, the area with the cutting edges 14 in for example, run over 3 to 5 cycles. Through the spray treatment with high pressure the burrs from the cutting edges severed.
  • the device shown in the drawing is suitable basically for deburring any cutting tools Size. However, are preferred on the inventive Device cutting tools in a range between Deburred about 1 and 40 mm shaft or tool diameter.
