Description

Cubic boron nitride is the second hardest material in the world invented successfully in 1957. The hardness of CBN’s single crystal is HV8000-9000 while the hardness of PCBN is HV2500-5000, so its abrasive resistance is considerably better than tungsten carbide and ceramics. With high temperature oxidation resistance at 1000℃, CBN will do not have any chemical reaction together with ferrous material at 1200-1300℃. So CBN material is ideal for cutting ferrous materials, the CBN cutting tools are used for cutting hardened steel, cast iron, sintered iron as well as powder metallurgy components. Features of Heavy Cutting PCBN Insert: 1. Welding area: 22mm², four cutting edges on both sides 2. Selected the most suitable imported PCBN materials 3. Larger cutting depth (1.5mm) improves production efficiency 4. High cost performance with competitive price, PCBN insert is a powerful tool for machining gears and bears Worldia Heavy Cutting PCBN Insert: 1. Premium CBN materials, U shape design increases the cutting depth and improves the machining efficiency, it is also less cost and better performance. 2. Clear mark of PCBN material makes it easily to recognize 3. Clear numbers of tips make the insert easily to management 4. The cubic boron nitride inserts can use double side of cutting edges which not only achieve the larger cutting depth, but also improve the machining efficiency (AP=1.5mm) 5. Special welding technology, the W shape welding joint increased the welding area which makes it more firmly 6. Clear serial number on carbide substrate makes it easily to track the PCBN insert quality and the feedback information
