CNC tool is a tool used for cutting in mechanical manufacturing, also known as cutting tools. Generalized cutting tools include both cutting tools and abrasive tools; At the same time, in addition to the cutting blade, the "CNC tool" also includes the tool bar and the tool handle and other accessories!

In the application of high-performance, high-precision CNC machine tools, in order to achieve stability and good processing efficiency, the general CNC tool from the design, manufacturing and use have put forward higher requirements than ordinary tools, CNC tools and ordinary tools the main difference in the following aspects:

1, high precision manufacturing quality

In order to stabilize the machining of high-precision parts, the manufacturing of tools (including tool parts) has more stringent requirements than ordinary tools in terms of accuracy, surface roughness, form and position tolerance, especially indexable tools, in order to ensure the repeated accuracy of the blade tip (cutting edge) after the rotation of the size, The size, accuracy and surface roughness of key parts such as the tool groove and positioning parts must be strictly guaranteed, and the machining accuracy of the base surface should also be guaranteed in order to facilitate the measurement of the tool and the size of the tool in the tool setting instrument.

2. Optimization of tool structure

Advanced tool structure can greatly improve the cutting efficiency, such as high-speed steel CNC milling tools in the structure has been more waveform edge and large spiral Angle structure, carbide indexable tools are used in the internal cooling, blade vertical mount, module replaceable and adjustable structure, and such as internal cooling structure, it is the general ordinary machine tool can not be applied.

3, the wide application of high-quality materials

In order to extend the service life of the tool and improve the strength of the tool, many CNC tool body materials are made of high-strength alloy steel, and heat treatment (such as nitriding and other surface treatment), so that it can be applied to large cutting amounts, and the tool life can also be significantly improved (ordinary tools are generally used after tempering treatment of medium carbon steel). In the tool edge material, CNC tools are more used a variety of new grades of cemented carbide (fine particles or ultrafine particles) and superhard tool materials.

4. Reasonable selection of chip breaker

The cutting tools used in CNC machine tools have strict requirements for chip-breaking slots. When processing, the tool continuously chips, the machine tool can not work normally (some CNC machine tools, cutting is in a closed state), so regardless of CNC turning, milling, drilling or boring machine, the blade is optimized for different processing materials and processes of reasonable chip breaking slot, so that the cutting can get stable chip breaking.

5, surface coating treatment

The emergence and development of surface coating technology is mainly due to the emergence and development of CNC tools. Because the coating can significantly improve tool hardness, reduce friction, improve cutting efficiency and service life, coating technology is used in more than 80% of all kinds of carbide indexable CNC tools.
