Abstract

The invention belongs to the field of mechanical cutting tool manufacturing, and relates to a preparing method for a WS2/Zr soft coating micro-nano composite texture ceramic cutting tool. Base materials of the cutting tool are ceramic. The method comprises the steps that firstly, the laser machining technology is adopted to machine micrometer textures of different morphologies and sizes on the front tool face of the ceramic cutting tool, then the laser machining technology is adopted to machine nanometer textures on a negative chamfer and the front tool face, and finally the medium frequency magnetron sputtering deposition plus multi-arc ion plating method is adopted to deposit a WS2/Zr soft coating on the surface of the cutting tool, wherein the WS2/Zr soft coating is arranged on the surface of the cutting tool, and a Zr transition layer is arranged between the soft coating and a base body. According to the ceramic cutting tool, friction between tool chips can be effectively reduced during cutting, the cutting force and the cutting temperature are reduced, and the abrasion resistance capacity of the cutting tool is improved, so that the service life of the cutting tool is prolonged. The ceramic cutting tool can be widely applied to dry cutting and cutting machining of difficult-to-machine materials.

Description

1. Technical field [0001] The invention belongs to the field of mechanical cutting tool manufacturing and relates to a WS 2 / Zr soft-coated micro-nano composite textured ceramic cutter and its preparation method. 2. Background technology [0002] Ceramic cutting tools are widely used in the cutting of difficult-to-machine materials due to their excellent characteristics such as high hardness, heat resistance and good chemical stability. However, during dry cutting, the friction between the cutting chips on the rake face of the tool is extremely severe, resulting in serious wear of the tool. Therefore, it is urgent to improve the friction of the cutting tool to increase its tool life. [0003] Self-lubricating tool is a kind of green dry cutting tool because of its anti-friction, anti-wear and lubrication functions. In recent years, my country has made great progress in the research on ceramic knives and surface textured knives. Chinese patent "CN200410024226.1" reported a...
