Description

Technical Field

[0001] The utility model relates to the technical field of processing knives, in particular to a processing knife. Background Art

[0002] At present, processing tools are tools used for cutting processing in mechanical manufacturing, also known as cutting tools. The vast majority of tools are machine-used, but there are also hand-used tools. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood to refer to metal cutting tools, and tools used for cutting wood are called woodworking tools. In addition, there is a special type of tool used for geological exploration, well drilling, and mine drilling, which are called mining tools. Tools play a vital role in mechanical manufacturing. They remove materials by cutting to help manufacture parts and products of various shapes and sizes.

[0003] At present, the surface temperature of machining tools is relatively high during long-term operation. Therefore, an internal cutting fluid channel is provided inside the tool. Through the internal cutting fluid channel, coolant and cutting fluid are transported to the cutting edge area of ​​the cutting blade used for machining, thereby achieving the purpose of cooling the tool. However, due to the high actual rotation speed of the tool, the contact time between the cutting fluid in the cutting fluid channel and the tool is short, resulting in poor cooling effect, which in turn affects the service life of the tool.
