Description

Novel diamond cutter for processing mesh surface

Technical Field

The utility model belongs to the technical field of cutting tools, and particularly relates to a novel diamond tool for machining a mesh surface.

Background

Cutting tools are tools used in machining for cutting operations. Most knives are machine, but also hand-held. Since tools used in machine manufacturing are basically used for cutting metal materials, the term "tool" is generally understood to mean a metal cutting tool. Metal cutting is generally divided into finish machining and rough machining, and the rough machining is most characterized by removing more material within a certain period of time, compared with finish machining. The most important objectives of the roughing are therefore: the time from the size of the raw material blank to the size required by the drawing process is shortened rapidly. Therefore, the rough machining has the characteristics of more removed materials, low cutting speed, large feed amount and tool consumption, low dimensional precision and low surface quality. There are still many areas of improvement in the existing roughing tools, such as the finish of the machined surface, which is detrimental to subsequent finishing processes. Therefore, it is urgently required to design a new diamond tool for textured surface processing to solve the above problems.
