Many people will find that the existing CNC horizontal lathe FANUC is not enough for us to process metal objects. At this time, someone will have a whim and continue to work. How hard metal can it process?
For ordinary hard aluminum alloy lathe turning tools, the general cutting hardness is between 20°-30°. If the hardness of the raw material exceeds 40 degrees, you need to use super hard lathe turning tools, such as CBN CNC blades or diamond blades, but super hard CNC blades are used. When inserting inserts, it should be decided according to the type and specifications of the lathe you are using at this stage and the main parameters of actual drilling. The cutting speed cannot be changed at will. A professional project engineer must choose for you.
Special coating hard aluminum alloy milling cutter for turning, can process HRC60 upper and lower heat-treated parts. The processing of high-hardness parts has nothing to do with whether there is a CNC machine tool or not, and has nothing to do with other types of CNC lathes. The key is the raw material of the CNC blade edge. Different workpiece materials must use relative tool materials, and coating materials and coating processing techniques are also different. Use different CNC blades to process different raw materials, and the main parameters of drilling must refer to the recommended values of the CNC blade manufacturer.
For high-speed steel lathes, the hardness of cutter milling metals is generally HB220, and the hardness of hard aluminum alloy lathe cutters is generally HRC40. For metals with higher hardness, CBN CNC blades or diamond blades are required. The number of cutting tools and the amount of cutting tools should be determined according to the specific conditions of the CNC lathe, product workpiece, raw material and processing technology.
Choose game props: The tool material is YT30 hard aluminum alloy. Negative rake angles are used for the main drilling cutting edges, and the intersection of the main and auxiliary front sides is convex, resulting in a large blade inclination. The compressive strength of the sharp knife is much greater than that of the ordinary CNC blade. The cutting edge half length (R=1~2mm) is larger than ordinary CNC blades, and it has good heat dissipation performance, anti-wear, and improves the service life of CNC blades. It is used for processing hardened steel products with hardness HRC62 on ordinary lathes.
