Definitions

  • V f f f Peripheralgrinding wheels include a hub portion having a central bore therein adapting the hub portion to be mounted on a shaft or spindle.
  • the hub portion is itself formed from some suitable support material commonly used in the art such as steel, bakelite or a light metal. Carried on the periphery of the hubportion in a position to make effective contact with a workpiece, is the effective grinding portion.
  • This portion commonly has a thickness of the, order of either onefourth inch or one-eighth inch (approximately 6 mm and 3 mm respectively).
  • This peripheral portion has abrasive particles such as diamond embedded in a cured synthetic resin or metal matrix.
  • Peripheral grinding wheels which incorporate abrasive particles such as aluminum oxide or silicon carbide can be suitably dressed both'forgood grinding efficiency, i.e. high stock removal, and for relatively low grinding efficiency, i.e. good surface finishing or polishing.
  • good grinding efficiency is first required then good polishing for a given workpiece, it is possible to dress the same wheel to achieve both effects.
  • dressing a peripheral grindingwheel incorporating diamond or cubic boron nitride is not easily achieved and hence different wheels have in the past generally been required to achieve both high stock remove] and good surfacefinish.
  • a peripheral grinding wheel having an'effective grinding portion containing diamond or cubic boron nitride abrasive particles, characterised in that the effective grinding portion, comprises two co-axial sections, the one section having coarse particles and providing, in use, a high stock removal (hereinafter referred to as the coarse section) and the other section having fine particles and providing, in use, a good surface finish (hereinafter referred to as the fine section");
  • the effective grinding portion consists of two such co-axial sections.
  • the effective grinding portion consists of a central fine section sandwiched between two outer coarse sections.
  • the coarse section is preferably wider than the fine I section the width in any given case being influenced by the amount of crossfeed during grinding.
  • the widths of the sections will preferably be 20 percent or more greater than the amount of crossfeed.
  • concentration of abrasive particle in the fine section or sections is greater than, preferably three times greater than, the concentration of abrasive particle in the coarse section or sections.
  • concentration is determined by taking the weight of abrasive particle per unit volume of the finished grinding element. The grinding element in'this ease-is the effective grinding portion. The concentration is expressed relative to a standard of where the weight of abra-
  • the preferred concentrations of abrasive particle in the fine section will vary with matrix being used. In the case of a cured synthetic resin matrix, the preferred concentration of abrasive particle in the fine section or sections is 100 to 150. In the case of a metal matrix, the preferred concentration of the abrasive particle in the fi'ne'section or sections is 100 to 300.
  • the preferred concentration of abrasive particle in the coarse sectionor sections is 50 to 100, irrespective of the matrix material.
  • the fine abrasive particles preferably have a size between 170/2 00 mesh and 300/350 mesh andthe size of the coarse particles is preferably between 60/80 mesh and 100/120 mesh.
  • the particles are metal coated.
  • FIG. 1 there is shown the effective grinding portion 10 of a peripheral grinding wheel which consists of two co-axial sections 12 and 14.
  • Section 12 is the fine section and contains fine diamond grit of size 170/200 mesh while the section 14 is the coarse section and contains coarse diamond grit of size 60/70 meshr
  • the grit concentration of the fine section is (i.e. 108 carats per cubic inch).while the grit concentration of the coarse sectionis 50.
  • the matrix material for both sections is cured synthetic resin and the-diamond grit is metal coated grit known as DX DA MC. e
  • the sections 22 and 26 are the coarse sections with grit size and concentration as for the section 14.
  • the section 24 is the fine section, with grit size and concentration as for the section 12.
  • The-matrix material is again synthetic resin and the grit is DX DA MC.
  • thewheels are used for grinding workpieces such as metal workpieces.
  • 'a grinding process can be carried out with cross-feeds from opposite directions.
  • the sharp edges 28 shown in' dotted lines
  • the outer sections 22, 26 will remove-most of the material being ground whereas the central section 24 will polish the surface left by the outer sections.
  • the grinding wheel 10 of FIG. I may be used for grinding with the crossfeed being applied in only one direction i.e. the crossfeed of the workpiece in the direction of the arrow 16.
  • the profile of this wheel, in use will have less curvature than that shown in FIG. 2, the curvature being indicated by solid lines in FIG. 1. This will have the effect of considerably reducing the waviness.
  • such a grinding process is more efficient as a greater amount of the diamonds are used during grinding. Therefore, lower wheel costs and better surface finish are obtained when an abrasive wheel, as shown in FIG. 1 is used with crossfeed in only one direction.
  • a peripheral grinding wheel having an effective grinding portion containing abrasive particles selected from diamond and cubic boron nitride abrasive particles, characterised in that the effective grinding portion comprises two co-axial sections, the one section containing coarse particles, from 60/80 mesh to 100/120 mesh in size, and the other section containing fine particles, from 170/200 mesh to 300/350 mesh in size, and the concentration of abrasive particle in the section containing the fine particles being greater than the concentration of abrasive particle in the section containing the coarse particles.
  • a wheel according to claim 1- wherein the efi'ective grinding portion consists of a central section containing fine particles sandwiched between two outer sections containing coarse particles.
