Generally speaking, the tools used in CNC machine tools should have high durability and rigidity, and the tool materials should have good brittle resistance, good chip breaking performance, and adjustable and easy replacement characteristics.
The correct use of the tool can make the cutting more stable, eliminate the sudden change of the feed direction between the adjacent tool paths, reduce the acceleration and deceleration of the cutting feed, and maintain the stability of the cutting load.
The precision required for the workpiece is higher, so the requirements of CNC machine tools for cutting tools will naturally be higher. There are many types of tools that can be used in CNC machining centers. The specific conditions of the different types of tools are as follows:
- If the tools are classified according to the manufacturing material, they can be divided into ceramic tools, cemented carbide tools, high-speed steel tools and superhard tools.
- According to the structure, it can be divided into four types: integral type, inlaid type, damping type and internal cooling type. The inlay type can be divided into welding and machine clamping. The machine clamping can also be divided into indexing and non- indexing. In addition to these, some types of tools are more special: for example, composite tools, reversible pattern tools and so on.
- According to the cutting process, it can be divided into milling props and hole processing tools. Milling tools include end mills, face milling cutters, mold milling cutters, etc.; hole processing tools include reaming tools, boring tools, and reaming tools And drilling tools.
