Electrical development of cast iron material
In 2012July, Sumitomo Electric industries developed a cubic boron nitride ( CBN ) content is high, can be processing cast iron and sintered alloy general machining model CBN material --" SUMIBORON BN7000", in today's listing.
For the machining of cast iron and sintered alloy sintered CBN CBN content is higher, the higher the hardness of tool. The company in the original 50000pressure on the basis of further improve the sintering pressure, established with higher density of sintering solidified CBN particle production technology. Successful in reducing the amount of adhesive materials. Moreover, the binding of CBN ( KB0) particles in the adhesive material, the company has also developed the ability to play a stronger adhesive force of new materials. With the help of these applications, SUMIBORON BN7000 can play the original product is 1.5 times more resistant to defect. Also for China's iron industry has brought new vitality.
