CNC tool is used in machining machinery for cutting tools, also known as cutting tools. Generalized cutting tools, including both cutting tools, and abrasive; At the same time, "CNC tool" in addition to cutting blade, but also including cutter arbor, tool holders and other accessories!
Applicate in the high-performance, high-precision CNC machine tools, in order to obtain stability and good processing efficiency, CNC cutting tools generally with more higher requirement compare to general cutting tools in design ,manufacture and application ,the main difference between cnc carbide tools and ordinary tools In the following areas:
1, high-precision manufacturing quality
In order to stabilize the processing of high precision parts surface, and therefore the tool (including tool parts) manufacturing precision, surface roughness, shape and position tolerance, etc. put forward more stringent requirements than the average tool, especially the indexable tool, to ensure The size and precision of the key parts such as the size of the cutting edge and the position of the tool body and the surface roughness must be strictly ensured. In order to facilitate the setting of the tool on the tool And size measurement, the base surface machining accuracy should also be guarantee
2, tool structure optimization
Advanced tool structure can greatly improve the cutting efficiency, such as high-speed steel CNC milling tools in the structure has been more use of the wave edge and large helix angle structure, carbide indexable tool is used in the cooling, blade mounted type, module Can be changed and adjustable structure, such as the internal cooling structure, it is generally can not be applied to ordinary machine tools.
3, the wide range of high-quality cutting tool materials
In order to prolong the tool life and improve the tool strength, many CNC tool 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 volume, and tool life Can be significantly improved (the general tool is generally used after quenching and tempering in the carbon steel). In the tool blade material, CNC tool is more choice of a variety of new grades of carbide (fine particles or ultrafine particles) and superhard tool materials.
4, the rational choice of chip breaker
CNC machine tools on the application of the chip breaker has strict requirements. In processing, the cutting tools are not working properly (some CNC machine tools, cutting is in the closed state), so regardless of CNC turning, milling, drilling or boring machine, the blade is optimized for different processing materials and processes reasonable off Chip groove type, so that cutting can be a stable chip breaking.
5, the surface coating treatment
The emergence and development of surface coating technology is mainly due to the emergence and development of CNC tool. As the coating can significantly improve the hardness of the tool to reduce friction and improve cutting efficiency and service life, so in all kinds of carbide indexable CNC tool for more than 80% have adopted the coating technology
