	The flanks of grinding wheel worms for Reishauer type machines have to be dressed with diamond dressing disks. Tooth form correction, such as crowning and tip relief, for example, can be directly built into the dressing disks. Diamond dressing disks can be re-lapped several times. To counteract excessive edge wear, PCD inserts or triangular shaped Maccle diamonds are sometimes used for edge reinforcement. Two methods are used for the manufacture of SPA and DSA disks: Type DS Infiltration method (Sintered bond): Diamonds are sintered with powder-metallurgical bond (the more wear resistant type), particularly suitable if the root of the grinding wheel has to be dressed.




	Type EL Direct plated: A single layer of diamond crystals is electroplated onto a preformed steel body.

Search		Due to the pitch of the profiled grinding worm and the necessary traverse feed rate, the grinding worm has to revolve at a very low RPM (50 - 90min) while the dressing disks revolve at up to 2650 RPM. The resulting speed ratio qd is around 4 or larger (9.15)
