Phenanthrene is special but the flying development of dislocation gear hob as machinist job, the gear that regards transmission as the spare parts appears particularly important. Ask to have exact geometrical figure not only to the treatment of gear, and have even high rate, efficient. The high speed that introduces development of company of a kind of blue banner now, efficient but hob of cutting of burden of dislocation hard alloy. This is modulus of a kind of modern treatment 5 above are thick those who cut the special economy of gear is thick cut hob. Designing conception is use economy but the union of razor blade of dislocation hard alloy and well-known rolling cut dominant position, inside formulary time, a large number of metals can be excised below tall cutting speed. Be being ground again to traditional hob is indispensible, and not was necessary here, this saved long wear to be mixed originally change a knife. On individual tooth wear away trace because of the process different. To gear, they can come true partly through shift be equal, because this hob always is included,differ wear away the cutting tine of trace width. Should use but when dislocation razor blade, these razor blade are in achieved the biggest wear away to be rotated when trace width or be replaced. Change dislocation razor blade or knife, need not come down hob from the discharge on the machine tool, saved the time that need worker worker so. To use this kind of hob successfully, requirement machine tool has enough good tigidity and want rotate speed and drive power. Phenanthrene is special but the structure of hob of razor blade of dislocation hard alloy includes system of a hob, in twist with bolt above it on knife and but razor blade of dislocation hard alloy, use a closed circuit to close next. Among them knife secure through impaction bolt in blade holder, there is groove of a helix on columnar cutter hub, groovy flank undertook grinding according to the guiding of cutter hub. The circle outside this cylinder that makes via grinding always maintains partly between two groove, to the knife having bearing effect. Knife go up to sell the decision below the guiding in groove through two cylinder its position, knife secure through bolt go up in cutter hub, the blade holder of razor blade of dislocation hard alloy is made on cutter hub tangential installation. Knife the blade holder crisscross that go up is arranged is the axial that maintains action to go up in cutter hub counterforce and what go up in gear is tangential force as far as possible small. But razor blade of dislocation hard alloy must enclothe blade of cutting tool cutting completely. But the amount of dislocation razor blade distributings with theirs depend on the dimension of the dimension of bit and gear. To give scrape or grinding first-rate obligate the amount, hob of hard alloy of dislocation razor blade can produce a root to cut on gear or can pour wine cup. To the gear of M5 ～ M10, each tooth of hob has a bit only, it enclothed entire tooth form length. To the gear of M11 above, the each tine side of hob balances opposite side of a razor blade. Below special situation, it enclothed entire tooth form length. Anyhow, this kind of hob is the high speed of course of study of contemporary gear cutting, ideal cutting tool of efficient, economy.
