The R22079-8160-40 with tall hill inserts factory of electric machinery of milling cutter Harbin finite liability company only then was being built 1951 is production big, medium-sized generate electricity equipment, large and medium-sized the key company that makes dc machine and equipment of control of form a complete set. Main product has: The control equipment of form a complete set of lead plane of hydraulic turbine, water turbogenerator, turbogenerator, power station and large and medium-sized hand in dc machine to wait for a few kinds big. With company of German Xi Menzi, United States day of house company, Japan establishs A Ersi of company, France to tell 12 states such as company of ABB of company, Switzerland on the west many 30 enterprise has collaboration to concern. Existing employee 6200 more than person, have equipment gross to be more than 3800, among them high spirit equipment 309, numerical control equipment 37. It is one furniture has the state-owned and large company that produces per year 5000 million to cover with tiles turbogenerator, 2500 million cover with tiles water turbogenerator group and 600 million tile fall productivity of dc electric machinery. For the Yangtse River at present the large water conservancy project such as dam of 3 gorge, arrowroot continent offers unit of water and electricity. Graph the bottleneck that the mill treatment of lamina of water turbogenerator of spare parts of lamina of 1 hydraulic turbine is efficiency of influence lamina treatment all the time, because blade semifinished product is cast, size is large (the 1) that be like a graph, and blade skirt edge is structure of screwy curved surface. Want the treatment on the mill of door of numerical control dragon in 5 axes linkage commonly, former technique uses treatment of mill of side of corn milling cutter, treatment efficiency is very low, machine a lamina to need commonly one, time of 2 days. And because machine tool price is high,wait for a reason, the amount of numerical control planer-type milling machine of 5 axes linkage is little, man-hour cost is high, more big the finished cost of blade. To resolve this one difficulty, hill collects those who use him research and development high to insert milling cutter, not only the treatment efficiency that improved blade, and implementation is machined on the numerical control planer-type milling machine of 3 rounds of linkage, reduced the finished cost of blade greatly. Use the R220 with tall hill now. 79-8160-40 inserts milling cutter handling time to shorten to 5 ～ 6 hours, also enlarged the size range of pipe bent of the spare parts at the same time. The treatment material of blade is the martensite stainless steel such as 1Cr13 normally. The treatment capacity of blade skirt edge has left and right sides of 50 ～ 70mm. Bit body uses the R220 of diametical Ø160mm.
79-8160-40) inserts milling cutter, bit uses SCET120612T-M14, t250M and SCET120612T-M14, combination of razor blade of two kinds of 620470 brands is used, cutting parameter is: Vc=200 M/min. Fz=0.
1mm/t, Ap=30mm, Ae=70 Mm, the machine tool is planer-type milling machine of numerical control of 3 axes linkage (the 2) that be like a graph. Planer-type milling machine of numerical control of graph 2 XKA2140 X 80A because the bed of iron of door of numerical control dragon of 3 axes linkage is used in home more general, because this seeks treatment partner very easily, alleviated the treatment pressure of planer-type milling machine of numerical control of the 5 axes inside the factory, also make machine efficiency to rise greatly at the same time. Current, means of the treatment that insert mill has applied to other component treatment. CNC Milling
