Definitions

  • the invention relates to a cutting-off disc having in its free, operative side face at least one recess and at least one bore adjoining said recess for accommodating in countersunk position a member for fastening the disc to a driving shaft.
  • Such a cutting-off disc is known.
  • the cutting-off disc 1 has a shape such that it has a dish-shaped central part 7.
  • a disadvantage of this known design is that the known cutting-off disc requires a special method of manufacture so that it is relatively expensive.
  • a further disadvantage of the known disc is that due to the very high speeds in cutting-off and to the relatively large dimensions of the disc the centrifugal forces in the disc may become very high. As a result of the dish-shaped central part 7 the force occurring may be so heavy that the disc may exhibit certain elastic deformations, whilst there is furthermore the risk that the disc has to absorb forces in a direction in which it is not sufficiently capable of doing so, which results in rupture. This means a necessary replacement of an expensive disc, whilst the rupture of a disc may be extremely hazardous to the staff and may cause damage to material and machinery:
  • the bores 11 serve to pass the shanks of the screws 12, which co-operate with a stretching flange 14 arranged at the end of a driving shaft 15.
  • Fig. 3 shows a cutting-off disc 16 connected with a clamping flange 17 by using bolts 18 screwed tight by means of nut 22 to the clamping flange 17, the bolts having heads 20 countersunk in recesses 19. With respect to the recesses 19 the heads 20 have a size such that they do not project in front of the front face 23 of the cutting-off disc 16.
