Gear cutter is a kind of cutting tool for machining gear, which is widely used in various fields of industrial production. Like all other industries at present, gear cutting tools are developing in the direction of environmental protection, high efficiency and low cost.

Traditional wet machining using coolant cooling, will form a large amount of oil mist in the process of processing, causing harm to the operator's health, a large amount of dust and oil mist emissions will seriously pollute the environment, and the dry cutting method does not need coolant, which not only reduces the cost of gear hobbing, but also can adopt higher cutting speed and improve the processing efficiency. Of course, dry cutting is not only for cutting tools and coating More demanding.

The multi-component nano composite coating prepared by Huicheng vacuum coating equipment on high-speed steel hob not only has good oxidation resistance, high-temperature wear resistance and diffusion resistance, but also can provide a turnkey project, including the pre-treatment, coating, post-treatment, quality inspection equipment, production process and abnormal treatment, etc. in the actual cutting test, it can also achieve To the international advanced coating technology level.
