It is possible to produce exact and complex shapes with tight tolerances upon dressing wheels by using diamond rolls. Diamond shape-rolls, also called pointed rolls, have a high number of diamonds and a very high lifetime. They are best suited to produce small exact radii as well as free shapes continuous path controlled. In this case the desired contour will be projected onto the grinding wheel by a CNC continuous path controlled interpolation of the axes. The diamond is electrically connected to the carrier. On the diamond profile roll the diamonds will be connected in negative order to the carrier via the same electrical method. Because of that, twist-free profiles can be transferred to the grinding wheel. On the reflecting contour far more diamonds are connected, which may have a technological effect on various advantages and disadvantages. Both variants are excessively used in mass production.
