5% . Output power with main shaft with respect to utmost favourable geographical position for this problem, designing the HPC thick milling cutter that has blade of outline appearance cutting is a wonderful choice it seems that. Mix besides cutting of high speed metal optimize the requirement that uses main shaft to output power beyond, in the economy that machines in milling, the service life of cutting tool also is a decisive factor. Two kinds of afore-mentioned cutting tool are had wear away representatively the phenomenon makes clear, after using cutty time, the meeting on the blade of hard alloy cutting that has outline appearance produces the local phenomenon that cut bits, highlight place to cut bits to measure more in outline especially. The big penetration of a cutting tool in high feed rate and HPC milling is measured, the power of lateral seat supports that highlights the cutting blade on place plus outline appearance is reduced, exceeded current the rigid limit of character of the most advanced atomic carbide metal, can produce huge machinery load. Choose flowing cutting blade or blade of choice figuration cutting? When use hard alloy carries milling cutter, the figuration cutting tool of above discussion is in the advantage of metallic cutting respect, cannot use in HPC cutting craft absolutely on the technology. Hard alloy carries milling cutter service life too short, can make the use cost of cutting tool raises greatly, the economy that can machine a method to this kind thereby generates serious doubt. Accept treatment power is great this be related is solid, the cutting tool that carries blame figuration hard metal milling cutter is designed with the geometrical figure that is matched by photograph of treatment material limits, this is a train of thought that suits HPC treatment it seems that. The rough machining of the rolled steel that intensity obtains 68HRC is had when treatment more when the rolled steel that high strenth is worth, corresponding cutting cannot have had big mechanical negative charge on blade. In addition, when cutting tool and workpiece are occlusive, as a result of the influence of feed wallop, what there can be generation to cut bits on cutting blade is dangerous. Considering these phenomena of the generation in using the blame figuration hard alloy that has geometrical figure to carry milling cutter, make choice of a = of the biggest γ of negative cutting horn - 10 ° . Use traditional tolerancepublic errand part, be patient of is more than the big wedge horn of 90 ° , this meeting balances the cutting blade of cutting tool greatly. In addition, groove helix angle is designed very greatly, can amount to γ = 55 ° , so that be in " decorticate cutting " below the concept, when processing brittle horniness data, correctional cutting accepts resultant force. Although have higher cutting rate, and taller below this kind of circumstance HSC machines speed of every tine feed, but measure through increasing penetration of a cutting tool effectively, criterion cutting rate of the metal can increase 10 times. The HPC concept in steely whole treatment promotes role in helix of chamfer of cutting of cutting horn / in 3 kinds of different combination, use this one technics, but include all rolled steel size range of pipe bent, the high-powered process capability that its have (speed of = metal cutting) can transform those who be a client is direct be benefited (= reduced manufacturing cost) .
