Successful modular tap combination plan is a when by function of the steeliness handle of tall tenacity and wear-resisting caustic combination of good hard alloy broach uses treatment program of kind of feasibility. This kind modular the cutting speed of tap is high-speed steel (HSS) one times of tap, cutting tool cost is less than its 50% even. Before early, car, mill and get treatment to begin to use modular cutting tool. Modular the advantage of cutting tool, it is above all can the component of accurate cutting tool that will differ according to the need of treatment undertakes be mixinged quickly be assorteded neatly. Through using modular cutting tool system, can reduce the preparative time of the machine tool not only, and the amount that can reduce treatment to produce manufacturer to provide cutting tool. Inside thread machining creates a field, mix in tap especially shape cutting tool respect, still offer without manufacturer on the market at present modular cutting tool. A few years ago, the expert of research and development of group of LMT cutting tool begins to try HPF of research and development (high-powered shape cutting tool) , be in later research and development Xchange is modular tap (graph 1) . Xchange is modular tap combines the advantage look of material of two kinds of cutting: Make the tenacity of the wear-resisting function of alloy material and high-speed steel forcedly. Pass the couple of these two kinds of advantages, cutting treatment efficiency advanced a new height. In the meantime, because screwy performance is good, can be in so carry taller cutting rate while the service life that prolongs cutting tool. In addition, xchange is modular the chuck of synchronous tap clamp that the partner Bilz firm that tap still used group of LMT cutting tool develops (graph 2) . Graph 1 use Xchange is modular the service life that tap can prolong cutting tool not only, still can raise cutting to machine speed to pursue 2 when processing work, xchange is modular the synchronous chuck of tap and Bilz company research and development is used along with all the others at present the tap on the market has 90% is HSS tap, cannot satisfy in batch treatment production to raise the requirement that machines security. And new Xchange is modular the success of tap should be to method: the hard alloy tap of wear-resisting caustic and tenacity tall steeliness handle union rises form separable assembly, after forehead tap exceeds service life, undertake changing. In the meantime, forehead tap has Poraris coat, prolonged its service life. New Xchange is modular silk attacks treatment rate is high, and exercise loop process is short, the treatment that dropped every whorl work greatly makes cost. Much practice experience makes clear, compare with HSS tap photograph, use new Xchange modular tap can make cutting machines speed to raise one times above. This kind new modular tap is to be treatment GG cast and GGG cast material technically simple work and cost short metallic work and of the design, the aluminium that uses its treatment to contain 12% silicon is made unchallenged also. Successful case pervades system of car, gear-box, fuel injection, crust and home appliance are made. New modular tap has in treatment decrease brace up function, decrease brace up degree and the material that process production work are qualitative direct and relevant. Common treatment needs to change 3 times only forehead tap, but be like after changing 10 times, need to change a new tap power. In undertaking big batch workpiece is machined, the cost of tap handle is negligible. Cost table bright: Use new Xchange modular tap treatment, its the 1/2 that the cost of every whorl is broach of use HSS-E glyph, the 1/5 of VHM broach. Supplier of spare parts of a car is inside time of a year, on a Heller MC 400 machine tool treatment made component of about 100000 motor. Life is the cutting tool of the HSS-E tap that its use to be able to machine 18450 whorl at most. And use Xchange is modular tap, its life is can machine 117670 whorl, be equivalent to prolonging service life 500% above. Compare with photograph of hard alloy tap, xchange is modular the manufacturing efficiency of tap rose 33% . As modular as Xchange of the manufacturing efficiency similar of tap still have HPF modular tap (graph 3) . Group of LMT cutting tool develops this kind modular tap is high-powered shape technical cutting tool, the whorl appearance of treatment is unlimited. In addition, its still have an advantage: Do not produce dig bit when machining whorl namely, raised the precision of the intensity of whorl and dimension from this. Graph 3HPF is modular shape cutting tool agrees with above all the treatment of steeliness workpiece and photograph of hard alloy tap are compared, modular tap place needed content of the tungsten in hard metal and cobaltic content to decrease to make an appointment with 85% , in the meantime, tap handle can repeat use, all n also reduced an in part. Its machine service life of working procedure on the safe side, cutting tool to grow. If undertake working processing work, can avoid those who affect the engine oil of human body health effectively to discharge. This shows, group of LMT cutting tool offers those who be used at the whorl inside treatment is modular tap not only economy is good, and zoology environmental protection, apply to big batch treatment to make.
