With 120 ° conical positioning, the blade is tightly fixed with the tool body to complete the cutting of difficult-to-machine material workpieces. The service life is 5-10 times longer than that of cemented carbide tools and ceramic tools.
This kind of blade is efficiently applied to the finishing of turntable bearing raceway, realizing the replacement of grinding by turning, and the efficiency is increased by more than 5 times compared with grinding. Polycrystalline Cubic Boron Nitride Blade has extremely high hardness and red hardness, and can withstand high cutting speed which is suitable for ultra-high speed machining of steel workpieces. It is an ideal cutting tool for high-speed machining of quenched steel, chilled cast iron, high-temperature alloy and other materials. For CBN blade can obtain good machining surface roughness when machining high hardness parts, cutting hardened steel with CBN blade can greatly improve machining efficiency on the premise of ensuring quality, and has the longest service life among high-speed cutting tools. Polycrystalline Cubic Boron Nitride Blade is suitable for the turning and milling of high-strength steel, mainly for semi finishing and finishing. Adopting PCBN blade in finishing machining is significantly more efficiency than cemented carbide and ceramic tools.
