Turbine machinery lamina is country of form a complete set one of crucial component that great and advanced motivation equips, its engineering capability reflected a state on older rate the level of advanced manufacturing industry. The turbine machinery lamina with serve as home important without limited company of stannic turbine blade creates a company, used a large number of domestic and international advanced lamina machines equipment. Especially 10 old before, the homebred equipment at that time still cannot satisfy craft requirement completely, production business of blade of machinery of our country turbine is purchased used machining center of many entrance lamina. Company of blade of the turbine that do not have stannum is in 2004-2007 year, purchased 10 Switzerland Sidalagehaikete HX151 8 axes machining center of 5 linkage lamina. The A axis that HX151 firsts wife uses the numerical control revolving stage of structure of worm of OTT worm wheel, as the addition of use fixed number of year, its machinery spare parts wears away serious, especially of worm wheel worm wear away increased backlash, easy cause blade to enter, vent one's anger the edge is cut too, the effect that causes to compressor lamina particularly serious (compressor lamina is entered, vent one's anger the edge is feeble) . Limited company of blade of the turbine that do not have stannum transforms a project to axis of A of social invite public bidding, inc. of equipment of Yantai round-the-world machine tool uses the plan of revolving stage of straight drive of DDR electric machinery to win the bid, and at 2017-2019 year the A axis that finished 10 afore-mentioned machining center transforms the task. The respect such as the treatment precision of axis of the A after transforming, efficiency, time to failure all promotes significantly, transform the consummation of the project, got client reputably. The A axis after transforming reachs target of the following technology: Rotate speed ≥200r/min, rated torque ≥500Nm, acceleration ≥10800°/s2, bearing ≥80kg, end panel is jumpy ≤0. 005/360 is spent, taper hole of A axis locking is jumpy ≤0.
005/360 is spent, ≤0 of fixed position precision.
009 degrees, repeat ≤0 of fixed position precision.
006 degrees. Revolving stage of worm of original worm gear and straight drive revolving stage compare comparative result to see next tables: The manufacturer of lamina of machinery of domestic production turbine is very much, inchoate bought entrance equipment, because use ingredient of fixed number of year, the A axis revolving stage that is faced with worm wheel worm wears away wait for a problem, former plant maintenance changes cost is very high. Now, transform in the light of what this kind of equipment has straight drive revolving stage upgrade, already had successful case, can achieve better economic benefits. In other sphere, if aviation engine lamina makes equipment, similar transform a project to also have very good application latent capacity. CNC Milling
