French Streit company is carapace of turbine of a professional production, flywheel and the automobile industry of intermediate carapace the business that distribute a packet. This company often comes up against treatment to have the stuff that challenges a gender, already became efficient and the expert that economic ground solves treatment difficult problem. Of Streit purchase manager Christophe Maldiney and craft engineer Pascal Marcotulio to discussing hill 3 tall the function of blade milling cutter. Streit group makes base and more than 650 employee composition by 8. Streit company is France the factory of Doubs is like the company such as Mercedes, Nissan, BMW and Volvo to produce a part for the most famous car manufacturer on a few worlds. This company uses the most advanced technology and technology, and seek the means that raises its to machine efficiency ceaselessly through the method that cooperates cheek by jowl with the supplier, perfect their core technology. "Our method is very simple, " of Streit purchase manager ShristopheMaldiney to say, "The income that we determine cutting parameter, computation is potential, undertake manufacturing experiment, actor to change technology, compare according to spare time and photograph of cutting tool life next, come accrual of test and verify. " after the process that having this kind of test and verify, come from a lot of cutting tool with tall hill to be introduced the product line of Streit, each already revealed his to make contributive ability to the profit of the company and efficiency. Win when Streit when machining turbine carapace contract for Nissan, it faces tall difficulty of a treatment material, contain nickel cast-iron problem. Milling of requirement of working procedure of this one treatment a 4mm is wide, the chamfer with deep 17mm. Streit evaluated the demand of this application, 335 what chose the diameter of hill tall cutting tool to be 125mm, wide 4mm. Milling cutter of 3 19 blade. The cutting tool that the hardness of workpiece material uses hereat to any using produces great stress, its are to may shorten as a result cutting tool life. The craft engineer Pascal Marcotulio of Streit complements: "The milling technology with high hill made sure bit is in its razor blade inside be held by firmer clip. This immediate result is the extension of cutting tool service life. " use cutting parameter is: Cutting speed 186m/min, head cut workbench feed is as high as 190mm/min, maintain next in 266mm/min. Rise in the round as use hill 3 tall the achievement of blade milling cutter, its productivity rose 20% , and cutting tool life also increased 35% . Of function raise the production that means Streit to be this workpiece now to be able to reduce a labour, and the quality that still promoted a spare parts (burr is fewer and exterior quality raises) .
