Carbide hobbing is suitable for high efficiency production with excellent hobbing precision, and moreover, it can make it possible to cut hard material gears. Recently it was been adopted by factories of automobile, electric and gear production. To decrease the cost of the tools, the authors want to lengthen the life of the carbide hob. In this paper, we report on the carbide hobs made by the PVD methods. For determining the life of carbide hob, the authors examined the effect of coating on carbide hobs. The results are as follows: (1) Coating a carbide hob of PVD methods can delay the occurrence of flank wear on a carbide hob. (2) It can delay the microchipping on a cutting edge with a small entrance. (3) It can delay the large chipping on a cutting edge with a large cutting volume. (4) It can delay the thermal crack on a cutting flank edge.
