Cemented carbide indexable CNC tools are tools used for cutting in mechanical manufacturing, also called cutting tools. In a broad sense, cutting tools include both cutting tools and abrasive tools; at the same time, "carbide CNC cutting tools" include not only cutting blades, but also accessories such as tool holders and tool holders.
Want to be applied to high-performance, high-precision CNC machine tools, while achieving stability and better processing efficiency, generally put forward higher requirements than ordinary tools for carbide CNC tools from design to manufacturing and use. The advantages of high-quality alloy indexable CNC tools are as follows:
High-precision manufacturing: In order to stably process the surface of high-precision parts, the manufacturing of tools (including tool parts) has stricter requirements than ordinary tools in terms of accuracy, surface roughness, and shape tolerances, especially for turning To ensure the accuracy of the size of the insert tip (cutting edge) after indexing, the size, accuracy, and surface roughness of key parts such as the tool body slot and positioning parts must be strictly guaranteed. At the same time, to facilitate the tool alignment The tool setting and size measurement of the tool instrument, and the machining accuracy of the base surface should also be guaranteed.
Wide application of high-quality tool materials: In order to extend the service life of the tool and increase the strength of the tool, many new grades of cemented carbide (fine or ultrafine particles) and superhard tool materials are used for the body materials of many CNC tools.
Selection of chip breaker: The cutting tools used on CNC machine tools have strict requirements on the chip breaker. During processing, the cutting tool will not work normally (some CNC machine tools, cutting is carried out in a closed state), so regardless of CNC turning, milling, drilling or boring machines, the blades are optimized for different processing materials and procedures. The chip flute type enables stable chip breaking during cutting.
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 increase the hardness of the tool, reduce friction, and improve the cutting efficiency and service life, coating technology is used in more than 80% of all kinds of cemented carbide indexable CNC tools.
