Tungsten Carbide Dry Cutting Hob Introduction

Tungsten carbide dry cutting hob is a kind of high-speed and environmental friendly numerical control gear hobbing technology. It can conduct efficient and high-speed primary or secondary cutting machining towards gear blank of quenched steel and carburizing steel materials

Materials of current gear cutting tools can be divided into four categories: tungsten carbide, ceramics, powder metallurgy high-speed steel and high-speed steel with high performance. Ceramic material is used in this field for a long time, but it is seldom used to produce complicated hobs while tungsten carbide material is more commonly used. China's current production of powder metallurgy high-speed steel and high-speed steel with high performance is still rare, but because china is abundant in tungsten carbide resources, thus this kind of material is supposed to become the leading material type in processing high-speed dry cutting gear hobs.
