Abstract

The invention discloses a high strength lathe tool blade machining technology. A lathe tool blade manufactured through the technology is high in surface hardness, the hardness of a core part is low, while the external cutting edge strength is guaranteed, the good toughness is achieved, breaking and cracking are not prone to occurrence, the cutting edge is not prone to being damaged, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of machining tool equipment, in particular to a high-strength turning tool blade processing technology. Background technique [0002] A turning tool is a tool for turning that has one cutting portion. Turning tool is one of the most widely used tools in cutting. In order to save materials and improve the tool change efficiency of lathes, many existing lathes use fixtures to hold turning tool blades instead of traditional turning tools. The turning tool blades are small in size and easy to replace. Compared with traditional turning tools, the cost is lower. Existing turning tool blades are made of high-speed steel or tool steel, and the blade itself has poor toughness, and is prone to cracking and chipping during use, which affects the processing quality. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a high-strength turning tool blade proce...
