  • the end surface truer a cup-shaped truer
  • a truer having one or a plurality of ribs can be exemplified.
  • the peripheral surface truer and the end surface truer may be those employing diamond grains or the like, or may be those employing columnar diamonds.
  • truing is used as including both truing in a strict sense and dressing.
  • both a work for adjusting a shape of the grinding wheel and a work for adjusting surface condition of the grinding wheel are named as truing.
  • Truing is, for example, to adjust an outer peripheral surface of the grinding wheel to a desired shape
  • dressing is to adjust surface condition of a grinding surface of the grinding wheel, that is, to correct a drop, crush, clogging and so on.
  • truing and dressing are not strictly discriminated as practical terms for field use.
  • Both an apparatus for truing and an apparatus for dressing are called as a truing apparatus or a dressing apparatus in the same manner. It is considered that this is because when truing the grinding wheel is conducted, dressing is also completed at the same time, in many cases.
  • the end surface of the grinding wheel is trued with the peripheral surface truer, and the peripheral surface of the grinding wheel is trued with the end surface truer.
  • contact between the grinding wheel and the correcting tool is made in a form of point contact or linear contact, whereby the contact area between them can be made as small as possible.

  • the inner diameter of the end surface truer of the correcting tool is made larger than the grinding width of the grinding wheel to be corrected.
  • the inner diameter of the end surface truer is B
  • the grinding width of the grinding wheel is TW
  • relation between the inner diameter B and the grinding width TW is within a range satisfying TW ⁇ B ⁇ 1.2TW to 3TW. This is because in case where the inner diameter B of the end surface truer is made larger than this range, the truing apparatus will be upsized and become disadvantageous in respect of space and cost.
  • the truing apparatus for the grinding wheel according to the invention is " characterized in that the end surface truer of the correcting tool includes a columnar diamond".

  • the monocrystalline diamond is likely to crack sharply, there is a problem that a surface shape of the correcting tool remarkably changes depending on a manner of cracking, and truing performance of the correcting tool becomes unstable.
  • the end surface truer including the polycrystalline columnar diamond which cracks minutely is used, whereby the end surface truer is worn substantially uniformly. Therefore, change in the surface shape of the truer can be decreased to the least, and the truing performance can be stabilized.
  • the end surface truer may be provided with the columnar diamond only, or may be also provided with a holding member for holding the columnar diamond. Further, the peripheral surface truer may be also provided with the columnar diamond.

Further, relative movements of the grinding wheel T and the end surface truer 32 are controlled by the CNC control device 20 so that the contact part of the end surface truer 32 at the left side, that is, at the opposite side may not come into contact with the peripheral surface of the grinding wheel T.
