When the tool cutting edge cuts into the material, extreme
shearing strain is generated in the chip formation zone. This
causes the material to flow off over the face of the tool
as a randomly shaped chip. During the course of this process,
thermal influences and friction forces result in wear of the
tool cutting edge.

The machine control variables relevant for the chip removal
process and the cutting-edge geometry can be determined and
optimized by the operator as variables to achieve the required
result.
The remaining variables determining the service life and
quality of the tool cutting edge are its thermochemical resistance
against the o.e., the forces determining their wear and their
mechanical workmanship (chipping of cutting edge).
In this respect, superhard polycrystalline SYNCUT-D and SYNCUT-CB
cutting edges by far surpass conventional hard cutting materials
such as hard metal and ceramic inserts.
Furthermore, SYNCUT-D and SYNCUT-CB can be used to turn and
mill materials which previously could be machined only by
grinding them.
