Cutting tools are tools used for cutting in machine manufacturing. Most tools are machine-use, but there are also hand-use. Since the tools used in machine manufacturing are basically used to cut metal materials, they can also be called cutting tools. Knives for cutting wood are called woodworking knives. China’s cutting tools wholesale industry and manufacturing industry are still dominant in overall terms.
Tool materials are roughly divided into the following categories: high-speed steel, cemented carbide, cermet, ceramic, polycrystalline cubic boron nitride and polycrystalline diamond.
Because of the needs of the development of the manufacturing industry, multifunctional composite tools, high-speed and high-efficiency tools will become the mainstream of tool development. Faced with the increasing number of difficult-to-machine materials, the tool industry must carry out material innovation and new product development as well as a more reasonable tool structure.
Cemented carbide materials and coating applications have increased. Fine-grained and ultra-fine-grained cemented carbide materials are the development direction; nano-coating, gradient structure coating and new structure and material coating will greatly improve the performance of tools; the application of physical coating (PVD) continues to increase.
The application of new tool materials has increased. The toughness of tool materials such as ceramics, cermets, silicon nitride ceramics, PCBN, PCD, etc. is further enhanced, and applications are increasing.
Cutting technology is developing rapidly. High-speed cutting, hard cutting, and dry cutting continue to develop rapidly, and the scope of application is rapidly expanding.
In addition to the rapid development of cutting tools, the development of threading tools is also becoming more and more rapid. In addition to electricians, there are more and more places where people need to use threading tools in their daily lives, such as pipes and wires. Many people like to do it themselves, and some people make their own threading tools when they are bored, and the results are very good. This also makes both the material of the threading tool and the threading tool very popular today. Of course, some people choose to use an automatic threading machine for convenience and effort. Of course, the automatic threading machine can be produced and naturally has its advantages, but many wire workers still choose to thread the thread manually. Both have their own advantages. How to choose depends on your own needs.
