When producing large part (grow in treatment course especially, wait for the circumstance with treatment irregular material to fall) the cutting tool with durable need. The manufacturer of world-renowned carpentry machine tool that is located in German Schopfloch -- bold and generous company is in milling encountered problem of cutting tool service life when large weldment, in convert after the milling cutter of Xtra · Tec that Waerte makes, the cutting tool service life of bold and generous company rose about 30% . Bold and generous use ST37 structure steeliness to make carpentry system " fundamental machine tool " . Schopfloch (stand by Fuluoyidengshidate) manufacturing department manager is used " fundamental machine tool " will describe what will assemble unfinished labour frame to go up the largest individual part, these spare partses include machine tool base / base (length varies from 4 ～ 12m) , slideway of bridge of column of form of boom, door, chain, individual spare parts is the heaviest amount to 6 metric ton. Normally, on milling machine treatment ST37 is without a problem, but bold and generous difficulty was encountered when spare parts of fundamental machine tool is machined. According to machine tool type, use blaze cut craft to be able to produce break on the spare parts, investigate its reason has at 2 o'clock: It is discontinuous cut; The 2 hot change in be blaze cut process make its have hard spot. Accordingly, in different cutting state all can be shown sometimes in simple steel structure. On the orbit that grows 12m in, begin to may differ with the milling deepness when the end a few millimeter, in addition, structure of a few thin walls returns meeting occurrence vibration and deflection, because of this cutting tool (especially rough machining cutting tool) must can answer these adverse states, the difference that measures like purify of interrupted cutting, hard spot, material, vibration and deflection. Use cutting blade more as far as possible to ensure, the octagonal milling cutter that the diameter uses to be 63 ～ 160mm when bold and generous company is growing exterior rough machining does type cutting, need 6 dragon door and double column milling machine to realize the optimum behavior of 2/3. Current, the milling that large part issues in optimal condition is relatively successful. Purchase manager Harry Pfost bold and generously to say: "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 or can have the job below finite cutting parameter only " . Because machine tool operator must observe the condition of workpiece and cutting tool ceaselessly, cannot have automatic production normally. If work flow relatively a long time is more difficult, in the machine tool operation admiral consumes a large number of labor power, and any working procedure in milling treatment process need to await. His complement says: "We machine a respect to had had 20 old experience in large part, because of the technology with this best requirement. In those day impossible with 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 " . Be in bold and generous, the large part that is used at assembling carpentry machine tool should pass blaze cut inside 10 days, solder, the flow such as machining and besmear outfit station, bold and generous and final chose Waerte the F4080 octagonal milling cutter of series of Xtra · Tec. Harry Pfost memory says: "Original we are information communication in Waerte hereon was obtained in the activity kind milling cutter and Tec of PVD Tiger · but the detailed information of dislocation razor blade, we think to be worth to undertake try out in manufacturing technology. " the fact is such really. Art of acrobatics of made of baked clay Er supports Joachim Schneider to complement: "At first, our maintenance the engineer has a test to material of horniness wear-resisting cutting, the WSP45 with final extremely strong hardness obtained better treatment result. 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 " . Solve interstitial problem bold and generous nowadays 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 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, if use,be the same as type milling cutter and razor blade, the circumstance before using milling cutter of Xtra · Tec is such, this kind of circumstance still can continue after using new cutting tool " . The company has begun to use new cutting tool on all milling machine that produce large part, manufacturing department manager believes firmly small part production to also will be changed because of cutting tool. To the experts of Schopfloch, collaboration is used (is interior is used not only) also be very important. Although each branch basically becomes independent to manage its to manufacture an activity and have a test alone when need, but when the project that has when place scores a success, schopfloch headquarters can signal the result elsewhere manufacturing branch, the information communication that about production efficiency promotes is quite important to each branch. Milling plan cutting tool: Waerte F4080 of octagonal milling cutter of series of Xtra · Tec, d=63 ～ 160mm, z=5 ～ 9, bit appearance is the WSP45 that uses PVD alumina coating for material of ODHT060512-F57, cutting tool (Tec of PVD Tiger · ) . Cutting parameter: When using sample of D=160mm milling cutter, vc=305m/min, n=607rpm, fz=0. 33mm, vf=1802 Mm/min, ae=155mm, ap= 2mm. Workpiece: The weldment of long 12m (the main component part of carpentry machine tool) , according to machine tool type, these workpiece can use as slideway of bridge of column of form of machine tool base or base, boom, door, chain and top roller pressure etc. 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, use at machining the spare parts of long 13m, SK50 receives a power. Accord with the brim of the requirement: Brim processing is pressing with a finger to 10 thousand flowers board, the brim cutting of real wood and layer pressing plate and brim agglutination. Because design number to charge direct machine tool (processing and agglutination the brim of position of two side level) , with one action of bold and generous company becomes the leader of world market. Bold and generous concept of design of another machine tool is the fixed treatment that is based on principle of traditional machine tool and fixed board. In machining a process, cannot avoid completely to need to change bit, tec of F4080 Xtra · has longer service life, make the frequency that change a knife is reduced greatly. Setting link: 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. As a holding company, a large number of business are owned in Germany and whole world, headquarters is located in German 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 system such as grinding, include to stride the control equipment of the machine tool and software with Yu Hao. Outside dividing Schopfloch, bold and generous there still are 10 plants in Germany, the cutting that all has his is produced and assemble craft. Schopfloch headquarters staff exceeds 1500 people, sum total of employee of whole world of bold and generous group 5000 people above. 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 about 100 ～ every months 120 new machine tools leave assemble a workshop. CNC Milling
