Railroad product applies efficient cutting tool to improve manufacturing efficiency

Regard the machining of railroad product as the enterprise, cutting treatment remains our main technology measure. Our company basically produces the component such as the piston on diesel locomotive diesel engine, supercharger, the material that its key forms a part is aluminium alloy of low carbon alloy steel, forge and nodular cast iron character, it is to forging for the most part semifinished product and cast semifinished product. Because product precision demand is very high, type of spare parts form is various, and treatment machine tool is numerical control machine tool for the most part, include center of milling machine of numerical control lathe, numerical control, turning, machining center to wait, accordingly the choice of the cutting tool of numerical control cutting to machining a process especially important. Importing cutting tool still is the mainstream: Be in 10 thousand or so about as a result of year of crop of our product, also be large quantities of quantities to produce pattern, the demand on the quality to cutting tool and service life is so higher, what choose for the most part is foreign entrance cutting tool, what basically choose like lathe tool is Yisika, agree the brand such as accept, what milling cutter chooses is Shanteweikekeleman, hill the brand such as porcelain of tall, Beijing, what tap chooses is the brand such as YAMAWA, OSG, give priority to with milling cutter of standard lathe tool, standard, basically use semifinishing machining and precision work, use low feed of high rotate speed, with the car era is ground, the value can achieve exterior surface roughness Ra=1.6 μ M is the following, the result is very right still. Annual cutting tool wastage is very big, once statistic passes, accumulative total more than kinds of 20 cutting tool year use up add up to about 339, total cost also is quite tall. Homebred individual plant also has been used during continent diamond, Taiwan a few cutting tool such as river source, opposite for show slightly inferior, basically be service life go up not as good as, for instance a razor blade, abroad imports can machine 30, and homebred can machine 25 or so only. PistonIn machining a process, standard cutting tool is occupied 6 into, the cutting tool that be not mark is occupied 4 into, what the major cutting tool that be not mark searchs is processing factory of domestic cutting tool the home uses his to only equipment undertakes making, early days also has looked for manufacturer of foreign brand tool, because the price is too high and give u, the price that although at present home is not mark cutting tool,machines manufacturer is cheaper, but product quality and treatment level still see one spot, the service life of cutting tool is inferior, pledge with the material of cutting tool with coating the technology matters. Tap is compared in our company commonly used, because piston and supercharger rely on bolt connection to assemble, the snail keyhole on the spare parts relies on tap treatment to come out. Look at present, compare without sexual price relative to taller tap, although have famous brand of YAMAWA, OSG, we also are being used all the time, but sexual price is compared is not very tall, this makes the tap that tall sex price compares with respect to manufacturer of need home tool, already good with cheap. Cutting cutting tool chooses undeserved meeting to bring about temperature of cutting muscularity, cutting as a result of cutting parameter tall, cutting tool is easy wear away, especially wrought alloy steel, aluminium alloy, cast-iron the spare parts that waits for different capable person to pledge, differ character besides cutting tool material besides, how to choose the most appropriate cutting parameter, want with reducing cutting tool to wear away to be weighed particularly. When to put forward to expect to domestic tool manufacturer: As the rapid development of machining industry, cutting tool industry of home also should catch up with modern pace, from research and development ability should rise ceaselessly to production level, accelerate the development of industry of domestic cutting tool. When does here put forward to expect to domestic tool manufacturer: (1) should master pulverous metallurgy high-speed steel to make cutting tool well, raise level of high-speed steel cutting tool. Performance of pulverous metallurgy high-speed steel is very superior, it is good to have high strenth, tall hardness, tall tenacity, tall wearability, machinability wait for a characteristic, inevitable in the future meeting replaces hard alloy predominate, the treatment industry that masters its to machine preparation to be able to give country is brought change brand-newly. (2) accumulates the application of new material of research and development, new coat. The large-scale construction of railroad of our country high speed and urban orbit traffic, brought huge market and business chance to new material market, believe cutting cutting tool also is met likewise such, satisfy the treatment need of each enterprise, get used to the client’s demand actively. (3) assures the dependability of output of cutting tool product and stability. The dependability of cutting tool quality and stability got the credit of the user not only, still built cutting tool brand famous degree. (4) has the capacity that offers money in time. Major manufacturing industry belongs to mass production, offer goods inadequacy temporarily, can lose a large number of order, company having damage is honorary. (5) technology personnel should be had seasonable and accurate the ability that solves spot cutting problem. Sometimes the likelihood because parameter of a certain cutting or what a certain angle chooses is impertinent, cause the effect that short of client wants, be badly in need of helping in the client at this moment when, no matter be the spot or phone,communicate, can take out a solution in time, help client solves a problem. Using efficient cutting tool is the measure that raises manufacturing efficiency to cannot be replaced, we should take the technology of cutting tool application seriously, raise the level that cutting of our country metal machines jointly.
