Definitions

  • the invention relates to a method for grinding in particular nickel-containing metallic workpieces, in which a grinding wheel, which is driven in rotation, is continuously dressed by a dressing wheel, which is driven in rotation, during the grinding of the workpiece by means of a continuous infeed of the dressing wheel.
  • the continuous dressing of the grinding wheel means that the grinding wheel always retains its exact shape. However, it has the drawback of a high consumption of the grinding wheel.
  • the grinding capacity i.e. the material-removal rate
  • the infeed rate of the dressing wheel is less than 1 ⁇ m/revolution, based on the grinding wheel.
  • the grinding-wheel speed of revolution i.e. the cutting speed, is at most 30 m/s.
  • the rotation of the dressing wheel is approximately 80% of the grinding-wheel rotational speed, running in the same direction as the grinding wheel.
  • the invention is based on the object of increasing the grinding capacity.
  • the dressing infeed rate is increased drastically to a level which is between 1 and 2 ⁇ m/revolution.
  • the grinding-wheel speed of revolution is set to at least 45 m/s.
  • the advance (table speed) can be set in such a way that the material-removal rate is at least 90 mm 3 /mms.
  • the grinding wheel is made from a highly porous material which forms an air volume of, for example, 50%, it is possible to improve the results still further.
  • the cutting speed can be increased to 60 m/s. It is then possible to achieve material-removal rates of more than 100 mm 3 /MMS, even for nickel alloys, which form long chips.
  • a grinding-wheel speed of revolution of 80 m/s and a dressing infeed rate of 2 ⁇ m/revolution it is possible to achieve material-removal rates of 300 mm 3 /mms.
  • the increase in the material-removal rate which is achieved by increasing the dressing infeed rate is explained by the fact that the increase in the dressing infeed leads to an increase in the sharpness of the tool.
  • the method using the sets of parameters according to the invention leads to faster wear to the grinding wheel, the consumption of the grinding wheel is surprisingly compensated for by the increased material-removal rate, so that overall the grinding capacity is increased.
  • the penetration depth of the grinding wheel which works using its circumferential surface, is preferably 3 mm.
  • the table speed can reach levels of over 1.8 m/min.
  • the abrasion to the grinding wheel caused by the dressing is greater than the abrasion during grinding.
  • FIG. 1 diagrammatically depicts the device for carrying out the method according to the invention
  • FIG. 2 shows sets of parameters with which optimum grinding results can be achieved.
  • the device for grinding the workpiece 1 comprises a grinding wheel 2 which is continuously driven in rotation and is operated at a rotational speed which is such that it acts on the workpiece 1 with a grinding-contact speed vs.
  • the direction of rotation is indicated by the arrow 2 ′.
  • the grinding wheel 2 is continuously dressed by a dressing wheel 3 which runs in the same direction 3 ′ and can be displaced in the direction of the arrow 3 ′′.
  • the dressing wheel rotates at approximately 80% of the rotational speed of the grinding wheel.
  • the circumferential surface of the grinding wheel 2 penetrates a depth ae into the workpiece 1 , which is resting on a moveable table 4 which can be displaced in the direction indicated by arrow 4 ′ at the table speed vt.
  • the grinding wheel consists of a porous material. 25% of the volume is formed by abrasive grain, 15% by a binder, while 50% of the volume of the grinding wheel is air. This is a porous grinding wheel. It is particularly suitable for nickel alloys.
  • the grinding wheel may have a specially reinforced hub (not shown).
  • the parameters illustrated in FIG. 2 are operating parameters at which the device illustrated in FIG. 1 gives good grinding results.
  • the first set of parameters 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 dressing infeed rate vfrd leads to an initially approximately proportional increase in the material-removal rate.
