Carbide and cubic boron nitride tool types corresponding to workpiece material
1. Carbide tools and materials for processing materials
Cemented carbide is one of the most important tool materials available today. Most of the turning tools, end mills and partial end mills, deep hole drills, reamers, etc. have been made of hard alloy. Due to the poor manufacturing process of cemented carbide, it is still very limited for complex tools. The hardness of cemented carbide is 89~94HRA, which is equivalent to 71~76HRC. Therefore, the cutting speed of cemented carbide is 4~10 times higher than that of high speed steel. Tool life can be increased by several tens of times, but its bending strength is low, toughness, shock and vibration.
Commonly used carbide tools correspond to the material of the workpiece:
1, YG3x / K01 / 1420; 92.5 / for cast iron, non-ferrous metals and alloys, hardened steel alloy steel material small cutting section high-speed finishing.
2, YG6 / K20 / 1900; 90.5 / suitable for cast iron, non-ferrous metals and alloys, non-metallic materials, medium to cutting speed, semi-finishing and finishing.
3, YG6x / K15 / 1800; 92.0 / Suitable for chilled cast iron, ductile iron, gray cast iron, heat-resistant alloy steel material, high-speed finishing, semi-finishing of small and medium cutting sections.
4, YG6A / K10 / 1800; 92.0 / suitable for high-speed finishing of small and medium cutting sections of chilled cast iron, ductile iron, gray cast iron and heat resistant alloy materials.
5, YG8/ K30/ 2200; 90.0/ Suitable for low speed roughing of cast iron, non-ferrous metals and alloys, non-metallic materials.
6, YG8N / K30 / 2100; 90.5 / for high-speed cutting of cast iron, white cast iron, ductile iron and chrome-nickel stainless steel alloy materials.
7, YW1/ M10/ 1400; 92.0 / medium-speed semi-finishing for steel, heat-resistant steel, high-manganese steel and cast iron.
8, YW2 / M20 / 1600; 91.0 / suitable for heat-resistant steel, high-manganese steel, stainless steel and other difficult-to-machine steel, low-speed roughing and semi-finishing.
Second, the material of the workpiece material corresponding to the cubic boron nitride tool
The cubic boron nitride tool is another superhard material tool that emerges after the synthetic diamond. Its characteristics are: hardness is second only to synthetic diamond (8000~9000HV), good wear resistance, high thermal stability, and can withstand high temperatures of 1300~1500 °C. In addition, it has good thermal conductivity and a low coefficient of friction. The cubic boron nitride tool can cut hardened steel, chilled iron, high temperature alloy, etc. at the cutting speed of ordinary steel and cast iron, thereby greatly improving productivity. When the precision parts of the car are hardened, the machining precision and surface quality are enough to replace the grinding. The domestic cubic boron nitride tool brand Hualing super hard HLCBN is exported to Europe and America. Valin Super Hard HLCBN Product Type and Scope of Application Category BN-K10 Welded for continuous finishing of gray cast iron and wear-resistant cast iron materials, such as brake drums, brake discs, flywheels, cylinder liners, etc. BN-K20 is suitable for the finishing of gray cast iron and powder metallurgy materials, and is suitable for high-speed fine boring BN-H10. It is suitable for continuous finishing or slightly intermittent finishing of hardened steel materials, such as “car grinding” gears. Bearings, etc. BN-H20 is suitable for medium/strong intermittent finishing and ultra-high speed finishing of hardened steel materials, such as various contoured shaft parts and high precision gears, bearing turning and small bore machining. BN-S20 is the perfect balance of overall impact resistance and wear resistance. It is the first choice for roughing and semi-finishing. It is widely used in gray cast iron, wear-resistant cast iron, sand-filled sand, white cast iron and various cast steels. Processing of steel materials. BN-S30 pursues high wear resistance and appropriate impact resistance, is suitable for high-speed finishing of gray cast iron, and is suitable for high-speed and efficient boring and milling.
