CHIP REMOVAL WITH
POLYCRYSTALLINE CUTTING MATERIAL
 
     
 

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.
