Definitions

  • the invention relates to a method for dressing profiled grinding wheels with diamond or cubic crystalline boron nitride as an abrasive, in which a dressing roller and a dressing aid roller made of silicon carbide or corundum, which is driven with a peripheral speed that is different from the peripheral wheel peripheral speed, is used.
  • a driven auxiliary dressing roller is provided as the dressing aid.
  • the grinding wheel For dressing and sharpening, the grinding wheel must also be braked to a peripheral speed of approximately 1 m / sec in this method in order to break diamond grains out of the surface of the grinding wheel to be dressed.
  • this process is associated with an uneconomically high expenditure of time.
  • a fixed dressing stone to sharpen a profiled grinding wheel dressed with a diamond dressing roller has proven to be imperfect. If, for example, a grinding wheel is to be provided with a thread profile, the teeth of which have only very small tip radii, the teeth of which, viewed in cross-section, are pointed, the subsequent use of the fixed dressing aid will undesirably round off the tooth tips if the relative speed between the fixed dressing aid and the grinding wheel is not very low. In addition, the relative speed between the grinding wheel and the dressing stone must be low in order to remove sufficient bonding material during sharpening. The use of the fixed dressing stone therefore requires a very low peripheral speed of the grinding wheel, so that the dressing process is time-consuming.
  • the dressing roller is a driven diamond roller and the relative speed between the grinding wheel and the auxiliary dressing roller is 0.5 to 6 m / s.
  • This enables dressing while maintaining a high rotational speed of the grinding wheel and thus also during work, because if there is only a relative speed of preferably 1 m / s between the auxiliary dressing roller and the grinding wheel profiled by a diamond dressing roller, this is sufficient on the one hand, to create a sufficient grain protrusion, and on the other hand too low for the risk of rounding the diamond or profile tips.
  • the diamond dressing roller can have a different circumferential speed than the grinding wheel, it being assumed that it is generally expedient to rotate the diamond dressing roller in the opposite direction to pre-profile a grinding wheel, so that, for example, the grinding wheel and also the diamond dressing roller rotate counterclockwise, While both discs are working in the so-called synchronous process during the final profiling, one rotating clockwise and the other counter-clockwise, thereby already a certain grain protrusion is then enlarged to the desired size by the dressing auxiliary roller working at a low relative speed.
  • the grinding wheel 1 shown in the drawing with a coating 2 of diamond or cubic crystalline boron nitride rotates clockwise according to arrow 3.
  • a rotary-driven diamond dressing roller 4 is provided, which rotates counterclockwise in accordance with arrow 5 and can be adjusted in accordance with arrow 6.
  • the dressing auxiliary roller 7 is driven such that it has a peripheral speed of 29 m / s when the peripheral speed of the grinding wheel 1 is 30 m / s, so that the relative speed between the two wheels is 1 m / s.
  • This low relative speed makes it possible to work out the individual grains beyond the bond when dressing the grinding wheel 1 by means of the diamond dressing roller 4, even if a workpiece 10 that can be delivered in accordance with the arrow 11 is also ground simultaneously with the grinding wheel 1 .
