Produce large part to need durable cutting tool, in growing treatment course especially, and it is more difficult to wait for a circumstance to fall. The bold and generous company that is located in German Schopfloch (Homag) encountered this kind of situation. Manufacturer of world-renowned carpentry machine tool is in the service life problem that milling encountered cutting tool when large weldment, convert consequently the cutting tool that Waerte makes. Use the milling cutter of Xtra · Tec©right; that Waerte makes, bold and generous can improve cutting tool service life about 30% . Bold and generous use structural steel ST37 to be made for its carpentry system " fundamental machine tool " . Schopfloch(stands by Fuluoyidengshidate) manufacturing department manager uses term " fundamental machine tool " will describe what should assemble unfinished labour frame to go up the largest individual part. These spare partses include machine tool base / base (its length varies to 12m from 4m) , slideway of bridge of column of form of boom, door, chain. Weight of the heaviest individual spare parts amounts to 6 metric ton. Bold and generous use structural steel ST37 to be made for its carpentry system " fundamental machine tool " . Schopfloch(stands by Fuluoyidengshidate) manufacturing department manager uses term " fundamental machine tool " will describe what should assemble unfinished labour frame to go up the largest individual part. These spare partses include machine tool base / base (its length varies to 12m from 4m) , slideway of bridge of column of form of boom, door, chain. Weight of the heaviest individual spare parts amounts to 6 metric ton. Machine ST37 to be without a problem on milling machine normally, but treatment of heroic spare parts of fundamental machine tool can encounter difficulty. According to machine tool type, blaze cut craft can produce a few break on the spare parts. The account that produces break has at 2 o'clock: It is discontinuous cut firstly; The hot change in be blaze cut process secondly makes its have hard spot. Accordingly, all pledge steel structure can show the cutting state with very big difference sometimes normally. The weldment below corresponding tolerance means the difference that material purify measures to increase difficulty possibly also. On the orbit that grows in a 12m, the milling deepness when begin and ending may differ a few millimeter. Besides, structure of a few thin walls returns meeting occurrence vibration and deflection. Cutting tool, especially rough machining cutting tool, must can answer these adverse states -- the difference that purify of interrupted cutting, hard spot, material measures, vibration and deflection. The cutting blade that can make spent likelihood much to ensure, bold and generous the octagonal milling cutter that uses diametical limits to be 63-160mm when undertaking rough machining to growing the surface. Treatment job is dry type cutting normally, need 6 dragon door and double column milling machine to realize the optimum behavior of 2/3, or 20-25kW. Up to now, the milling that large part issues in optimal condition is relatively successful. However, "In the past, should encounter not steady working condition or cutting are irregular when material, the milling cutter that we use faces problem of cutting tool life ceaselessly, so we must interrupt treatment to perhaps can be only below finite cutting parameter have the job. " automatic production normally unworkable, because operator of this machine tool must observe the condition of workpiece and cutting tool ceaselessly. If working flow is more, this is unworkable, because it will expend a large number of manpower to be on machine tool operation, milling machines any working procedure in the process to need to await. Purchase a manager to complement: "We machine a respect to had had 20 old experience in large part, because of the technology with this best requirement. At that time impossible that with us the means of place conception uses contemporary cutting tool and material of cutting cutting tool to do today. We think its machine the expectation that cannot have satisfied us, begin to seek the cutting tool solution with credible other so " . We chose Waerte finally the milling cutter of F4080 octagonal razor blade of series of Xtra · Tec©right; . Harry Pfost recollects: "We are information communication in Waerte at first hereon was obtained in the activity kind milling cutter and Tec©right; of PVD Tiger · but the detailed information of dislocation razor blade, we think to be worth to undertake try out in manufacturing technology in those days " . The fact is really such. Waerte's technology supports say of personnel Joachim Schneider: "At first, our maintenance the engineer has a test to material of horniness wear-resisting cutting, but the treatment outcome with passed the WSP45 with extremely strong hardness finally to obtain better. Because material is irregular, the wearability with the hardness of cutting material and PVD alumina so good coating offerred quite high treatment reliability for us " . Bold and generous typical and large part is machined. The crackle that combustion causes -- the hardness that points to interrupted cutting and brim solves interrupted cutting problem nowadays, bold and generous special to machining a process to feel satisfaction. Manufacturing preparation and Walter Gau of group leader of numerical control process designing say: "In cutting parameter changeless circumstance falls, the service life of milling cutter of Tec©right; of new-style Xtra · is made an appointment with than was being lengthened before 30% " . So good outcome also has positive effect to other craft, walter Gau emphasizes: "Manufacturing branch is very interested in the cutting tool solution that changes consistently; For example, use with type milling cutter and razor blade, before turning and using milling cutter of Xtra · Tec©right; , the circumstance is such, this kind of circumstance still can continue after using new cutting tool " . So the company has begun to use new cutting tool on all milling machine that produce large part. Additional, manufacturing department manager believes firmly small part is produced also the change cutting tool of benefit from benefit from. To the experts of Schopfloch, collaboration is used (is interior is used not only) it is very important. When the project that has scores a success, schopfloch headquarters can signal the result elsewhere manufacturing branch. Although each branch basically becomes independent to manage its to manufacture an activity and have a test alone when need, but the information that promotes about manufacturing efficiency exchanges to each branch word is quite important. Milling detail cutting tool: Waerte F4080 of milling cutter of razor blade of anise of series of Xtra · Tec©right; . Appearance of D=63-160 Mm, Z=5-9, razor blade is the Tec©right;) of WSP45(PVD Tiger · that contains PVD alumina coating for material of ODHT060512-F57, cutting tool. Use at the sample cutting parameter of D= 160mm milling cutter: Vc= 305m/min(n=607 R/min)fz=0. 33mm(Vf=1802mm/min)ae=155mmap=2mm workpiece: As carpentry machine tool (" fundamental machine tool " ) the 12 M of main component part grows weldment; According to machine tool type, these workpiece can be bridge of column of form of machine tool base or base, boom, door, chain slideway and top roller pressure wait. Material: Have break (interrupted cutting is caused) the ST37 with blaze cut brim. Process a system: Milling machine of a double column and 5 planer-type milling machine, with the spare parts that grows at machining 13 M. SK50 receives a power. The brim that accords with a requirement is located in German Schopfloch(to stand by Fuluoyidengshidate) limited company of equipment of machinery of industry of bold and generous timber (Homag Holzbearbeitungssysteme GmbH) held water 1960, it is the biggest company below division of bold and generous group. It is a holding company, a large number of business are owned in Germany and abroad. Its headquarters is located in Schopfloch, range of products includes to be used at the machine tool of plank treatment and furniture line of business, batteries and equipment of whole set plant. The expert of Schopfloch is in charge of considering to the brim is handled and supply the machine tool that has newest control and operating system, and elsewhere sawing of expert criterion research, auger cut, the other system such as grinding, include to stride machine tool control equipment of the system and software with Yu Hao even. Besides Schopfloch, they still have 10 plant area in Germany, the cutting that all has his is produced and assemble craft. What brim processing points to is brim cutting and brim agglutination, no matter be,be aimed at 10 thousand flowers board, real wood or layer pressing plate. Charge direct machine tool through designing number (its processing and agglutination the brim) of position of two side level, total position becomes the leader of world market at the with one action of bold and generous company of Schopfloch. The concept of another machine tool that bold and generous place designs is the fixed treatment that is based on principle of traditional machine tool and fixed board. The employee number of Schopfloch headquarters exceeds 1, the global employee sum total of 500(group exceeds 5, 000) . The turnover last year is the group about 7.
1.8 billion euro. Exit is occupied 75% , among them 25% exit reach home of Europe allied country. Be in only Schopfloch, have every months make an appointment with 100-120 stage new machine tool to leave assemble a workshop. CNC Milling
