Abstract

The invention discloses a method for manufacturing a microstructure carbide blade. The method comprises the steps that a carbide blade forming mold with a microstructure feature is manufactured through a cubic boron nitride grinding wheel with a microstructure feature on the surface, carbide powder is rolled through the carbide blade forming mold with the microstructure feature to form a microstructure carbide blank, and vacuum sintering is carried out on the microstructure carbide blank to manufacture the microstructure carbide blade. The method for manufacturing the microstructure carbide blade has the advantages of being simple in preparation process, low in cost, good in repeatability and high in practicality, and mass production of the microstructure carbide blade can be achieved.

Description

technical field [0001] The invention relates to a method for preparing a micro-textured cemented carbide blade, which belongs to the field of tool preparation and cutting processing. Background technique [0002] During the cutting process of aluminum alloy, stainless steel, titanium alloy and other metal materials, the sticking phenomenon often occurs, which seriously affects the processing quality and the durability of the tool. [0003] In order to solve the above problems, the solution commonly used at home and abroad is to use micro-texture to reduce the friction between the chip and the tool surface, thereby reducing the cutting force and improving the durability of the tool. Commonly used micro-texture construction methods are femtosecond laser machining, micro-EDM, electrolytic machining, etc., and these methods are used to form micro-texture structures on the tool surface. [0004] A significant defect of the above-mentioned methods is that the process equipment is...
