Definitions

  • the invention relates to a method for grinding, in particular, nickel-containing metallic workpieces, wherein a rotationally driven grinding wheel is continuously dressed by a rotationally driven dressing wheel during the grinding of the workpiece by continuous feed of the dressing wheel.
  • the continuous dressing of the grinding wheel has the consequence that the grinding wheel constantly maintains the exact shape. But it has the disadvantage of high grinding wheel consumption.
  • the grinding performance, the chip removal rate is determined by the table speed. This is set in the prior art so that the removal rate is less than 30 mm 3 / mms.
  • the feed speed of the dressing wheel is less than 1 ⁇ m / rev. related to the grinding wheel.
  • the grinding wheel rotation speed, ie the cutting speed is a maximum of 30 m / s.
  • the rotation of the dressing wheel is about 80% of the Schleifraditchiere and is in line with the grinding wheel.
  • the invention has for its object to increase the grinding performance.
  • the problem is solved by the invention specified in Anspuch 1.
  • the Abrichtzustell Malawi is dramatically increased to a value of between 1 and 2 microns / Umdr. lies.
  • the grinding wheel rotation speed is set to at least 45 m / s.
  • the feed rate (table speed) can be set with these parameters in such a way that the time removal volume is at least 90 mm 3 / mms.
  • the grinding wheel is made of a highly porous material which, for example, forms an air volume of 50%, the results can be improved even further.
  • the cutting speed can be increased to 60 m / s.
  • the chip removal volumes of more than 100 mm 3 / mms can be achieved, even for long-chipping nickel alloys.
  • the claim 3 accordingly requires a grinding wheel rotation speed of more than 50 m / s, preferably more than 60 m / s and a feed corresponding to a removal rate of more than 100 mm 3 / mms or 150 mm 3 / mms.
  • chip removal volumes of 300 mm 3 / mms At a wheel rotation speed of 80 m / s and a dressing feed speed of 2 ⁇ m / rev. can be achieved chip removal volumes of 300 mm 3 / mms.
  • the increase in the removal rate achieved by increasing the dressing delivery speed is explained by the fact that increasing the dressing delivery leads to an increase in tool sharpness. This is also blamed for the barely observable increase in normal force.
  • the method with the parameter sets according to the invention has the result that the grinding wheel wears faster.
  • the consumption of the grinding wheel is, however, surprisingly compensated by the increased removal rate, so that overall the grinding performance is increased.
  • the penetration depth of the working with its peripheral surface grinding wheel is preferred 3 mm.
  • the table speed can reach values over 1.8 m / min.
  • the grinding wheel removal by dressing is greater than the abrasion during grinding.
  • the device for grinding the workpiece 1 consists of a grinding wheel 2, which is continuously driven in rotation and is operated at a speed that it attacks with a sliding contact speed vs on the workpiece 1.
  • the direction of rotation is designated by the arrow 2 '.
  • the grinding wheel 2 is continuously dressed by a co-rotating 3 'dressing wheel 3, which is displaceable in the direction of the arrow 3 ".)
  • the dressing wheel rotates at about 80% of the grinding wheel speed
  • the grinding wheel 2 engages with its peripheral surface with a depth ae in the Workpiece 1, which is located on a movable table 4, which can be displaced in the direction indicated by arrow 4 'with the table speed vt.
  • the grinding wheel is made of a porous material. 25% of the volume is grain, 15% volume is a binder, 50% of the grinding wheel volume is air. It is a porous grinding wheel. It is especially suitable for nickel alloys.
  • the grinding wheel can have a particularly reinforced hub (not shown).
  • Particularly suitable for this purpose is a grinding wheel according to the Austrian patent application A 314/2000.
  • the parameters shown are operating parameters in which the in Fig. 1 shown device provides good sanding results.
  • the first parameter set corresponds to the prior art.
  • the second set of parameters shows how a slight increase in the grinding contact speed and a drastic increase in the Abfeichtzustell Supreme vfrd leads to an initially approximately proportional increase in the Zeitspanvolumens.
  • the in the Fig. 2 The parameter sets shown were determined by performing loop experiments in which the cutting speed vs and the infeed speed vfrd of the dressing wheel were kept constant and the feed (table speed) vt was increased stepwise.
  • the in Fig. 2 The value for the chip removal volume shown corresponds to the experiment with the highest feed, in which a sufficiently good sanding result was achieved.
