Because the circumgyrate campaign of main shaft has around milling cutter head, the compensation that need not require in that way like other machine tool consequently moves, the burden that reduced circumgyrate actuating device greatly wants the lamina of turbine of economic ground treatment and compressor, raise very tall requirement to machine tool and cutting tool. The 5 axes of BX 151 Win-Win that Starrag-Heckert company develops machining center, can satisfy quality of pair of precision, surface and the high demand that reduce workpiece cost to put forward (graph 1) . The 5 rods that are used at whole to machine turbine and compressor lamina machining center, the novel point of its machinery plan depends on main shaft tilting ahead. Because circumgyrate dot is located in on milling cutter head, when answering have a change of luck to move consequently nonexistent the danger that collides with baseplate. Accordingly, other axis also is restricted in the compensation motion when circumgyrate in the smallest degree. Because need quality minimum of motion, can achieve very tall acceleration to be worth consequently. Of force cut bit of clingy frame working face. Cutting component of force always is absorbed by main shaft directly. The machine tool structure of tall stiffness has balance stability, can reduce the negative charge of circumgyrate actuating device, because satisfy the fundamental premise requirement of high accuracy treatment however. Graph the dot is located in the 1 circumgyrate as a result of the main shaft that tilts ahead place of milling cutter head, when answering have a change of luck to move consequently nonexistent the 15000r/min of main shaft turn up of compound bearing uses the danger that collides with baseplate this kind of machining center, the milling job of the lamina of steam turbine and gas turbine can finish complete set to machine after one-time clamp (graph 2) . To turbine lamina, this machining center can be apart from treatment with the center of 800 Mm almost all blade place (the intermediate zone of predestined relationship of lip of area of going from place to place, face of blade, entrance and exit lip predestined relationship and foliaceous foot and foliaceous coping) . Blade carries ministry and blade root ministry to undertake machining with standard cutting tool. Blade is OK and direct undertake cutting into parts cutting on machining center. Besides be used at machining turbine lamina, this machine tool still agrees with 5 axes machine appropriative, if be used at machining milling to measure huge whole set,rotate component, only course or multistage BLISKS and structural part. Graph on 2 turbine treatment and compressor lamina almost all place can put undertaking machining main shaft of HSC electric machinery on machining center also is development of Starrag-Heckert company proper motion in same table, main shaft jacket has unit of compound bearing, its refrigeration and HSK interface. The asynchronous electric machinery of main shaft uses vector control, power is 27 KW. The biggest revolution of main shaft is 15000r/min. Because the tigidity of the machine tool is very tall, consequently the potential power of main shaft can be developed entirely, can achieve very high cutting rate already, also can achieve big torque and high power. This uses big diameter cutting tool to undertake the economic benefits of rough machining will produce positive effect to rising. When machining blade, tall acceleration is more significant than high rate: 0.

The acceleration value of 5g is very conspicuous for the machine tool to this kind of norms. Such it agrees with already preliminary precision work, also apply to final precision work. Won't produce oscillatory trace. Because the circumgyrate campaign of main shaft has around milling cutter head, also need not resemble other machine tool consequently in that way compensation moved. Rose to machine precision and cutting stiffness so, can drop the negative charge of circumgyrate actuating device. Component of all machine tool cooperates machining center to assemble each other have control equipment Sinumerik 840 D and the servo drive that match to it and advocate gearing. Like be the same as all other component on the machine tool, servo drive and control equipment and direct ball whorl transmission mutual a course is exact cooperate. Graph the slide of axes configuration cross of machining center BX 151 Win-Win and frame install 3 5 axes to go up in firm baseplate, frame is firm ground secures what go up in the foundation (graph 3) . Baseplate bearing is worn two crossed tool carrier, and frame criterion with circumgyrate actuating device tilt installed surface leads perpendicular slide. The installation on the machine tool has fluid to press gravitational equalizer, the quality that is in charge of pair of all and perpendicular motion undertakes compensating. The drive installation of transverse slide is on frame, be located in the central position of milling cutter head. The guide plate of linear Hua Zhu of 4 big norms is responsible and transverse slide very close to each other is unoccupied place and high accuracy ground glides, transverse slide criterion bearing is worn fore-and-aft slideway and fore-and-aft actuating device. Annular actuating device does not have clearance closely, tailstock criterion but fore-and-aft shift, workpiece is placed between both. The machine tool uses rigid structure, have decrease crackajackly brace up function, can undertake stable cutting, process stability is tall, cutting tool life is long. The slide cutting bits of workshop tilts installation, can make cut bits and refrigerant to arrange flow to move. Station interface accords with the tray system of Starrag-Heckert in the center of workpiece, all machine tools that make manufacturer with this are all and compatible. Cutting tool wearing installs a knife to have the separate unit that hold a knife, also can undertake operating in machining a process. Cutting tool box can assemble and unassemble at any time box of annular cutting tool contains change a knife implement, direct installation is on the side of the frame of machine tool base. Cutting tool box can follow fashionable dress discharge during treatment. Unit of feed a machine is standard configuration. Of meantime walk time is short, the time that change a knife is short, arrive from cutting consequently the time between cutting is short. Advocate operation door jacket has safe glass, consequently operator is observing or input process data while, also can observe milling process (graph 4) . Graph the door is observing the 4 machines that carry installation safety glass or input process data while the desire that the milling result that observes milling process machining center satisfies a client completely. With this kind new-style 5 axes machining center, the machine tool series that Starrag-Heckert makes machine turbine lamina attain at perfecting. Such, machining center also got 5 axes of existing SX and HX series odd main shaft complement. CNC Milling CNC Machining
