Job shops buys cutting cutting tool every time, the means that should differ with two kinds actually pays cost for this cutting tool. What pay above all is to purchase cost. Buy the price to know very easily -- tool supplier can quote directly. The cutting tool of a lot of manufacturer heretoes into devoir analyse. But, subsequently and those who come still have auxiliary cost, the integrated cost of all time that although use place of this kind of specific cutting tool,need expenditure, energy and extra step. This kind of auxiliary cost is aeriform, often be ignored easily by job shops, and did not undertake anatomize to its -- the proportion that although it is normally in cutting tool totle drilling cost,holds is larger. Those are dogging the job shops that every kinds of cutting tool does weller on real totle drilling cost, often can obtain first-rate cost effectiveness. Recently, the deep Kong Zuan of Yi Sika company cuts cutting tool supplier and bore with a reamer cut product manager Tom Edler to list manufacturer of component of a car to be in a crucial Kong Jia is versed in medium exact to using cutting tool to undertake cost is analysed. He says, cost analyses data to make clear, although differ of cutting tool buy price six to one, but so costly that much efficient cutting tool can save treatment totle drilling cost effectively actually. The basis analyses a result, what this manufacturer decides to abandon price of every razor blade be less than 5 dollars is cheap cutting tool, and choose price of a kind of every razor blade the efficient cutting tool of nearly 200 dollars. Although this is planted of new-style cutting tool buy the price to want 40 times more expensive above, but its assist the be far ahead on finished cost economicly. This specific treatment is the aperture of a blind on main body of fuel injector of car of the treatment on lathe of CNC numerical control. Workpiece material can be formed agglutinant cut bits. These cut bits to pile up very easily in Kong Zhong, return meeting card to be between hole wall and boring lever sometimes. Treatment dimension may be below the circumstance that does not have any adumbrating occurrence out of tolerance, because this factory must is opposite,every workpiece one by one undertakes checking. The cutting tool that Yi Sika company puts forward to differ completely with a kind replaces boring cutter to undertake machining. The Bayo T-Ream bore with a reamer that this company offers cuts a system by bore with a reamer of interchangeable hard alloy the head has the steeliness knife handle that changes orgnaization blocking an opening quickly to form with. The cooling passageway of cutting tool interior can cut cooling fluid guiding the 6 cutting blade of the head to go up to bore with a reamer. High-pressured cooling fluid and photograph of appearance of knife chamfer geometry are united in wedlock, can drive outside cutting bits to flow to give opening side by side up. With Chan Ren photograph of boring razor blade is compared, the design that this kind of bore with a reamer cuts a head is quite complex, accordingly its price is gotten high also much. But manufacturer discovery, it can save more finished cost. Company explanation says Yisika, the first respect of economic cost depends on needing bought bit amount. The experiment makes clear, the cutting tool life that a bore with a reamer cuts a head is razor blade of a boring 5 times (by be calculated by amount of treatment spare parts) . More cost save those who come from above to mention all sorts of auxiliary cost factors, include time, energy and extra measure. Concrete analysis is as follows: (1) time: This bore with a reamer cuts a head to have 6 cutting blade, and odd blade boring cutter has blade of a cutting only. To the same negative charge that cut bits, bore with a reamer cuts the feed rate of the head to be able to raise 5 times, handling time is the 1/6 of boring only. (2) energy: The cutting tool life with boring briefer razor blade is meant, must often break down treatment, in order to change bit -- because the whole life of boring razor blade still includes,arrive from dislocation of blade of a cutting especially the time of another cutting blade. And bore with a reamer cuts a system to be able to reduce cutting tool to install a number already, also can reduce the frequency of the new cutting tool that order. (3) extra step: This bore with a reamer cuts a system effectively control is agglutinant cut bits, the opening that treatment gives has very good consistency, can make sure dimension stability maintains it is in tolerancepublic errand limits. Accordingly, can cancel to add man-hour to pursue an examination measure indispensably with boring system. The real cost that machines blind aperture with cutting tool of these two kinds of cutting analyses as follows: Data is comparative: Odd blade boring cutter, Bayo T-Ream bore with a reamer cuts systematic aperture (inch) : 0. 75, 0.

The blind hole that 06 above analysis has not include to cancel to go out to treatment has the cost with economic institute of 100% all inspection. Although take no account of this one, the treatment totle drilling cost of every workpiece also was reduced 60% -- although Bayo T-Ream bore with a reamer cuts systematic price,want costly much. Edler thinks, "Productivity is mainer balance factor, its importance exceeded cutting cutting tool. " what those enterprises that are based on cutting tool price to choose to machine craft consider is cutting tool purchases cost only, and every finished cost with was ignored the most significant. Want to overcome this kind of prejudice, the key is the shadow cost that wants anatomize to use more efficient craft to be able to be saved. Those who need an attention is, the new approach that discovers economic cost often needs to change train of thought. Edler says, manufacturer of main body of this fuel injector uses boring craft to machine this key aperture before, and after its changeover cuts craft for bore with a reamer, with respect to can remarkable economic finished cost. Often also appear in milling treatment similar case. A lot of job shops can lead purify of its milling metal raise one times, but do need to take the step that violates intuition so -- change cut deep quantity to compare smaller now big feed milling cutter with a kind. This kind of milling cutter can undertake milling with very high feed rate, of its productivity rose to exceed greatly reduce cut profound influence, because this can save treatment totle drilling cost. In the treatment of such, the method that can enhance cost effectiveness often machines a method to be widely divergent with the tradition of some kind of spare parts or feature. CNC Milling
