In fact, in machining, which tool is chosen depends mainly on the material to be processed and the nature of the process. This is not only the processing efficiency and processing quality, but also the life of the tool. Today, CNC tool manufacturers share with you how to choose the right tool in the CNC machining process.
High hardness workpiece materials are machined with higher hardness tools, so the hardness of the tool material must be higher than the hardness of the workpiece material.
The higher the hardness of the tool material, the better its wear resistance. For example, when the amount of cemented carbide is increased, the strength and initial strength are increased, while the hardness is reduced, which is suitable for roughing; when the amount of cemented carbide is reduced, the hardness and wear resistance are increased, which is suitable for processing. High temperature mechanical properties of the tool. Particularly suitable for high speed machining.
In general, pcbn, ceramic tools, coated carbide and tcn-based carbide tools are suitable for processing metals such as steel. PCD cutters are suitable for processing non-ferrous materials such as aluminum, copper and their alloys and non-metallic materials.
Specifically, cubic boron nitride is suitable for surface treatment of various difficult-to-cut materials such as hardened steel, hard cast iron, superalloy, cemented carbide, and surface spray materials. Diamond cutters are suitable for processing all kinds of wear-resistant non-metallic materials, such as FRP powder metallurgy billets, ceramic materials, etc.; various wear-resistant non-ferrous metals, such as various silicon-aluminum alloys; various non-ferrous metal finishing. Ceramic cutters are suitable for cutting all kinds of cast iron (grey iron, ductile iron, malleable cast iron, cold-excited cast iron, high-alloy wear-resistant cast iron) and steel (carbon structural steel, alloy structural steel, high-strength steel, high-manganese steel, hardened steel) . It can also be used to cut copper alloys, graphite, engineering plastics and composites. Coated tools meet the high-speed machining needs of a wide range of steels and cast irons, heat resistant alloys and non-ferrous metals. Cemented carbide is mainly used for processing cast iron, non-ferrous metals and non-metallic materials.
