Additionally, Cam Relief grinding produces finer surface finishes on the cutting tool due to the motorized rotation of the grinding operation. This offers greater edge integrity. Finer surface finishes offer fewer microscopic imperfections that can eventually lead to premature tool wear or failure. These improved surface finishes translate directly to improved finishes on the work piece.
Though cylindrical margins are desirable in some applications, such as the cutting of brass products, they are more often detrimental to the cutting of other materials, such as aluminum, copper and stainless steel. Cylindrical margins, in some materials, tend to overheat the cutting edges through friction with the work piece. Overheating the cutting edges can lead to annealing and spalling – chipping or flaking away, of the cutting edge. Cam Relief grinding offers the option of producing cylindrical margins, while conventional cutter sharpening does not.
Finally, Cam Relief machining data is specified on production drawings. This assures that the form relief on tools from any production order are manufactured identical to one another.
