Optimize lathe tool to improve manufacturing efficiency substantially

65mm. Because used course of shape of this kind of geometry to optimize,the machine tool adds what work efficiency leads to rise is, the cutting tool that the surface has new-style coat exceeding nitrogen glossily pursues 4 now. With Supermini lathe tool. Can machine 12000 solid a system of fixed quotas for marketing, essence of life cuts exterior surface roughness to be able to be stabilized achieve Ra0.
08µm ～ 0.
14µm. And cutting tool service life increases one times plan 5 cutting tool are optimized after finishing. Urs Steinemann(is left) the favorable positive result that proves to quality inspection not only with Christoph Schlaginhaufen expresses satisfaction, and corresponding ground reduced quantity of do poorly done work over again to optimize make inside work efficiency of aperture lathe tool raises one times Andrea Esposito is director of workshop of much axis machine tool. Basically be in charge of daily (every week 7 days, everyday 24 hours) manufacturing project. Majority auto industry uses turning spare parts is the production on the machine tool that is in charge of in him, its model spare parts is to adjust the control a powerful person that oil of exhaust, platoon uses. Say according to Esposito. The machine tool of this workshop includes lathe of much axis of Tornos MultiDeco 20/6. The product that basically is used at machining batch to go to 1 million in 200 thousand above (graph 2) . Meanwhile, the short line product that this workshop still is in charge of machining batch to go to 50000 in 20000. But no matter why be planted circumstance, must achieve the exterior quality of the requirement and public errand. Material of this kind of workpiece basically is steel, stainless steel and brass. Came two years in the past, this company is machined with MultiDeco machine tool all the time 1.
4105 stainless steel make solid a system of fixed quotas for marketing. Diameter of the aperture inside the spare parts uses Horn Supermini lathe tool to machine to 5.
65mm. When treatment, rotate speed is 2700 ～ 2800r/min, feed rate turns for every 0.
01mm comes 0.
02mm, with much axis lathe but minutely treatment 6 spare partses. Esposito says: Original, what we use is the lathe tool of another manufacturer. In the meantime, try out a variety of replacement scheme, in an attempt to raises the dependability of treatment and the quality level that reach a requirement. We just succeeded really after using Horn bit. Say according to Schlaginhaufen, this company is to use lathe tool of Horn standard type to undertake machining at the beginning, but appeared a lot of problems, if grow,cut bits, the material function of each batches of products has change to wait. They find a kind of cutting tool structure that can break bits very quickly, but action the pressure on bit is very great, easy cause bit to rupture. Add on the blade breaking bits of H form cutting tool a deputy blade can make critical role stability comes down. Nowadays, blade grinds the cutting blade not need of new-style cutting tool, also won't rupture. Accordingly, this company had a kind of special bit that solved the problem that break bits. And can press a demand beforehand buy breakpoint. The special razor blade that designs by standard structure even also is such. After using investment of afore-mentioned new-style razor blade a few months only, inside workpiece apparently when machining groove. The problem that never has had a kind before appeared. This may be different material character be caused by. Schlaginhaufen says, after changing bit of better with quality coating exceeding nitrogen, this problem also was solved (graph 3) . "This kind of coating that develops by Horn company is had exceed large fine construction. The surface is slick. And the product than before more heat-resisting and wear-resisting. " Esposito emphasizes: "Use the Supermini that the course optimizes, capacity of spare parts treatment is jumped from 5000 rise 12000. Because form cutting problem of groove was solved before 3 months, a knife can use 2 days continuously, and have everyday before should change a knife. The exterior quality of treatment is able to rise substantially. From daily examine daily in light of, the exterior surface roughness that the regulation must achieve is Ra0.
20µm(graph 4) . The place before collecting in order to uses bit. Be in a long time only later. We dare not assure to achieve a requirement. Use Horn bit now, make treatment through subsequently light, exterior quality can be stabilized achieve Ra0.
08µm ～ 0.
14µm. Did not optimize in cutting tool before. Produces part often needs do poorly done work over again. Must reach the qualitative star level of the requirement completely through add treatment ability. The cost that controls treatment boils after dropping a car nowadays, qualitative check charge also decreases subsequently (graph 5) . " cutting tool is optimized should last in different and excessive phase, supermini can be applied to through optimizing mass-produced. With respect to its complex degree machines parameter with what change ceaselessly for, be in whole in optimizing a process, a few companies (the investment of Hauml;&ni, Dihawag and Horn) is larger. Nevertheless, this project still lasted one year between half. Project expense explained this category eye is mixed to the partner the importance that how solves mass-produced problem. Schlaginhaufen emphasizes, with respect to this project character, sincere letter is the foundation that cooperates with Häni company. Steinemann thinks: If we miss effectively work, we must are with sincere letter this, close the relation of we and supplier and client. As a result of the leader of departmental door, be like Mr Esposito, be in know sth like the palm of one's hand to the advantage of the supplier. Can fall in essential condition so, can make quick response to the client's requirement. Cutting tool is optimized is a durative project. Disclose according to Schlaginhaufen. The newest project that having is to let operator sleep good become aware. This respect still is put in a few problems. If there are 10 to be able to move reliably in 12 knives of much axis lathe, this project succeeded. This can make he is at ease. Let him feel better. His responsibility collects the information of the user and feeling uninterruptedly namely. Give manufacturer its. Horn criterion assemble these information. If special cutting tool is standardized ceaselessly, optimize the process can be accelerated and affect actively to other user generation. This is the thing of cutting tool itself not just, and it is to be engaged in every week the lifetime career of generator. The pressure with increasingly severe dark of our user face L, want to produce the product with lower, more reliable price quickly. As cutting tool the supplier must face up to this kind of pressure. Need is offerred ceaselessly more reliable with more durable cutting tool. Want to make a process more to understanding as far as possible. In Arch, what this kind of production process faces the whole world to compete namely is mass-produced. CNC Milling
