5 axes machine a machine tool to process medium application in 3 yuan of impeller

Introductive the crucial core component that 3 yuan of impeller are the equipment such as compressor of air-blower of high speed of centrifugal air compressor, only course, vapour, through rotating acting carries a fluid (clean air, vapor) what carry place the fluid is static pressure can the pressure that step up needs to systematic place. The discretion of equipment efficiency, depend on greatly design and make a standard of the type selecting of 3 yuan of impeller, lamina face. And compressor of air-blower of only course high speed, vapour serves as liquid waste of system of waste gas to decoke, MVR to evaporate respectively core equipment of the system, having crucial effect to the integral efficiency of whole set of equipment. Graph sketch map of 3 yuan of 1 impeller is current, domestic and international of 3 yuan of impeller blades model face treatment all uses machine tool of 5 axes linkage, our company is compressor kind product production makes specialization enterprise, had introduced Germany to breath out silent C40U/C50U, Germany at present Aomeite GS650, Switzerland the 5 axes such as STC1000/STC1250 machine Sitelage machine tool. 5 axes of series of haing silent C machining center is vertical, workbench swings (cradle type) machine tool, have tigidity good, stability the characteristic with tall precision of good, treatment. And Sitelage STC series 5 axes machining center is head of horizontal, main shaft place motive bed, main shaft power is great, workbench carrying capacity is strong. Our company is a basis the different characteristic of these two kinds of machine tools undertakes manufacturing plant layout. 2.

　 of brief introduction of machine tool of Ha Mo C50U (1) the numerical control system of the machine tool: Machine tool of Ha Mo C50U uses system of numerical control of Hai Dehan ITNC 530, monitor of color of 15 inches of TFT. Graph 2 Ha Mo C50U 5 axes machining center 　 (2) the configuration of the machine tool: Ha Mo C50U uses integral type to cast lathe bed, additionally axis of A, C makes a whole through special design and lathe bed. Such design makes Ha Mo's machine tool can come true very big bearing, c50U can come true bearing 2 000kg. And, precision of the tigidity of the machine tool, stability, geometry rises greatly. In the meantime, maintaining a respect, as a result of A axis installation is in of lathe bed exterior, slideway installs the upside in lathe bed, make maintenance is used convenient, fault rate is lower. Journey of linear axis X, Y, Z is 1 000mm, 1 100mm, 750mm respectively, corresponding linear and rapid floating rate is 60m/min, 60m/min, 55m/min, linear acceleration is 6m/s2, 12 000r/m In of main shaft rotate speed, the cradle turns over corner to spend from - 130 ° ～ 100 ° . 3.

Sitelage 　 of brief introduction of STC1000 machine tool (1) the numerical control system of the machine tool: STC1000 machine tool uses Sitelage numerical control of Sinumerik 840D S L controls a system, have compositive P L C. Computer number is controlled (CNC) use technology of SINUMERIKMDynamics5 axis milling machine, its include 5 axes treatment to be checked with batten fill (A, B and C batten) , before look up (L O O K -ahead) function, trends controls the function such as the function beforehand. The operating system uses WIN-XPProEmbSys, 19 inches make the same score operation board OP015A, take LCD of color of 15 inches of TFT (filmy clavier) . (2) the configuration of the machine tool: The machine tool provided commutative work platform, 1 000mm of × of tray dimension 1 000mm, central carrying capacity achieves 3 000k G. Rotate speed of working main shaft 20 ～ 8 000r/min, m of · of 940N of the biggest torsion, 95mm of diameter of the bearing before main shaft, 37kW of electric machinery rated power. 6min-1 of A axis rotate speed, · M of 4 000N of rated moment of force, 60 ° of circumgyrate area ＋ ～ - 100 ° . Journey of linear axis X, Y, Z is 1 700mm, 1 600mm, 1 950mm respectively. Graph 3 Sitelage STC1000 workbench and main shaft can see from machine tool configuration, sitelage STC1000 machine tool is more convenient when impeller workpiece is installed, workbench carrying capacity is large. Machine tool main shaft is better relative to tigidity, electromotor power is great, undertake burden of large vane wheel is machined aptly. 4.

The machine tool of two kinds of type is using the different characteristic in the process actually 5 axes of 5 axes machine tool are normally by 3 linear axis is adscititious a rotor and one swings the axis comprises, its structure means has very big difference however. Different configuration can make the machine tool is in the respect such as rigid, dynamic function and precision stability produces a few difference. Basis of machine tool of 5 axes linkage swings of the axis swing means cent is two kinds, one kind is main shaft head swings, another kind is workbench swings. 5 axes machine the vertical that the workbench that Ha Mo C50U is a kind of models swings machine tool, sitelage STC1000 is the horizontal that head of a kind of main shaft swings 5 axes machine a machine tool. Breath out the integrated characteristic of silent C50U machine tool: Main shaft tigidity is good, treatment efficiency is tall; Cutting tool clip runs length opposite shorter; Of the feed direction of the main shaft when treatment and cutting tool rotate center from beginning to end coincide, appearance error is small; Workbench swings the 5 axes treatment of means and the dimension that way of spare parts standard can machine when 3 axes are machined are identical, 5 axes linkage won't reduce treatment travel. But larger to diameter and high dimension vane wheel, the problem that installs dependability with respect to existence workpiece (workbench swings) , also put in the problem that workbench swings to be interfered with cutting tool. Sitelage the integrated characteristic of STC1000 machine tool: Used mechanical drive main shaft, main shaft tigidity is so better; Machine tool space is large, the installation of large vane wheel is more convenient, stable and reliable. When be being machined because of the machine tool, main shaft swings the meeting when angle is swinging the journey is eaten off inside plane, bring about what can machine when 5 axes are machined thereby decrescent of measure of the greatest work; Wear considering main shaft head generate interference likely when main shaft, cutting tool swings with workpiece tray, the cutting tool knife handle that uses so will be relatively longer, and of impeller come back to different, the distance that main shaft head should keep away from also differs somewhat. 5.

The difference that machines craft is on different machine tool, the machines craft otherness of 3 yuan of impeller is clearly. The diameter of 3 yuan of impeller that machine tool of Ha Mo C50U machines aptly is in φ 450 ～ 850mm. Because machine tool main shaft is electric main shaft, main shaft bearing is bearing of pottery and porcelain, by turns in 3 yuan of leaves thick when leaving, if technique used cutting of big feed burden, can cause harm to machine tool main shaft, affect machine tool precision and service life. The side chooses in cutting tool knife handle, thick mill adds man-hour to choose side solid knife handle to be able to satisfy a requirement commonly. The diameter of 3 yuan of impeller that machine tool of S T C1000 machines Sitelage aptly is controlled in 800 ～ 1 250mm. What machine tool main shaft uses is mechanical transmission way, cutting of burden of divisional big feed can choose when thick mill of 3 yuan of impeller is machined. When thick mill is machined, cutting tool knife handle should choose cutting tool of join of head of custom-built lengthen knife handle, screw, in order to make sure cutting tool whole is rigid. 6.

The machine tool of 5 axes treatment that epilogue breaths out silent C40U/C50U workbench to swing machines a diameter to slant aptly 3 yuan of little vane wheel, machine tool stability is good, treatment efficiency is tall, precision is reliable; STC1000 machine tool machines Sitelage aptly 3 yuan of impeller with largish diameter, workpiece installation is stable and reliable, the machine tool can undertake burden cutting. Current, our company had configured series 5 axes machine a machine tool, can satisfy company compressor kind the demand that the product expands.
