Carbide cutting tools has big market potential

Carbide Drill Bits etc carbide cutting tool for hard turning, this technology after ten years of development and promote the application of the huge economic and social benefits. The following to roll processing industry, for example, indicating the popularization and application of hard cutting tool production.

Many large roll enterprises superhard cutting tool shortage of car chilled cast iron, hardened steel and other types of rolls, roughing and fine cars, have achieved good results 7 an average of 2 to 6 times the processing efficiency, saving processing timeand electricity 50% to 80% as the Wuhan Iron and Steel Company plant Roll hardness HS60 to 80 chilled cast iron rolls roughing, semi-refined car, cutting speed increased 3 times, a car rolls, saving electricity, working hours, feesmore than four hundred yuan, saving tool costs nearly a hundred dollars, has made tremendous economic benefits. My school FD22 cermet turning HRC58 ~ 63 86CrMoV7 hardened steel rolls (Vc = 60m/min, f = 0.2 mm / r, ap = 0.8 mm), single-edged continuous cutting roll. Diameter up to 15000m (tip after the flank wear with the maximum width VBmax = 0.2 mm) to meet the requirements of turning instead of grinding.

Domestic ballast pump plant 70% to 80% with super-hard tool. The ballast pump are widely used in mining, power and other industries, is urgently needed products at home and abroad, its sheath, shield is the high hardness HRC63 ~ 67 Cr15Mo3 cast iron pieces. Difficult turning this material due to a variety of tools in the past, so had to resort to the annealing softening after roughing and then quenching processing technology. Superhard cutting tool, the smooth realization of a hardening processing, eliminating the annealing and then quenching the two processes, saving a lot of hours of work and power.

In automobiles, tractors, and other industries in the crankshaft, camshaft, drive shaft machining, cutting tools, measuring processing and maintenance of equipment, often encounter the problem of hardened workpieces. Of a Rolling Stock Plant, Equipment Maintenance on the bearing inner ring processing, the hardness of the bearing inner ring (material GCr15 steel) to HRC60 inner ring diameter f285mm the grinding process, the grinding allowance uneven, need 2h to wear; superhard cutting tool first, only 45min processed into an inner ring.

Superhard cutting tool after years of research and exploration, China has made great progress, however, Carbide End Mills cutting tool is not widely applied in the production. The main reasons are the following aspects: production enterprises, the operator of the superhard cutting tool for hard turning effect do not know enough, generally considered only grinding hard materials; that the tool cost is too high. The hard turning initial tooling costs than ordinary carbide cutting tools (for example the PCBN more than 10 times more expensive than ordinary Carbide), but their assessed in? On the cost of parts than the grinding is low, and bring benefits much better than ordinary carbide; mechanism of super hard tool is not enough; super hard tool specification is not sufficient to guide the production practice.

Therefore, in addition to in-depth study of the mechanism of super hard tool, but also the need to strengthen the superhard cutting tool.
