One, brief introduction number controls a machine tool, machine tool of abbreviation numerical control (NC, numerical Control) , it is a kind of when will 30 years apply computer technology, automata, nicety integratedly to measure with the advanced technique such as machine tool design development to rise new-style machine tool; It is automation of implementation machine tool, and even a when innovate whole production process important way. 2, the composition of machining center is general machining center trades knife unit box, slide carriage, workbench, automatically by lathe bed, main shaft (ATC) , the partial composition such as device of ark of cooling box, lubricant box, control, pneumatic, case. 1, the fundamental component that lathe bed lathe bed is a machine tool, its situation getting power is more special. Lathe bed not only should bear the weight of the athletic component such as slide carriage, workbench and athletic concussion, and bear even the weight of the component such as pillar and the strong report ark that are hanged on pillar, numerical control ark, manipulator and knife library. 2, box of main shaft of main shaft box includes structure of main shaft drive, main shaft structure, cutting tool automatic clamp orgnaization, main shaft is directional orgnaization (stop an orgnaization definitely) , the part such as main shaft electromotor. Structure of main shaft drive uses alternating current machine and servo electric machinery commonly, conduct campaign to main shaft through taking drive, make main shaft reachs certain rotate speed thereby, will complete cutting treatment. Now economy machining center, general use vector transducer as drive component, the result is favorable. 3, trade knife unit automatically (ATC) trade knife unit automatically (ATC) have two kinds of forms commonly, one kind takes manipulator, another kind is do not take manipulator (change a knife without the arm namely) . This device is the mark of machining center distinction at CNC Milling. Decisive effect is having in treatment. 3, applied example stage installs V2 transducer to explain in the application of machining center: 1, main shaft by 4 extremely frequency conversion electric machinery procrastinates move, rotate speed limits is 50~6000r/m, according to the rotate speed of actual condition set of treatment. 2, main shaft electric machinery introduces drive of vector V2 transducer, can realize linear velocity to give a function, satisfy treatment requirement, prolong the service life of cutting tool. Because use, is vector controller, although be in low rotate speed (low frequency) move fall to also can output taller torsion smoothly, in order to satisfy the treatment need of different spare parts, can replace structure of traditional scroll bearing main shaft completely, and structure of this main shaft is simple, compact, OK the stepless speed regulation with true implementation. The rotate speed of this main shaft measures signal to control output frequency by exterior imitate, craft is machined in what differ (be like; Rough machining, finish machining) the rotate speed with different need, the imitate that can differ by output of numerical control system right now measures voltage signal to give transducer, realize different rotate speed, open at the same time stop signal to also be controlled by numerical control system, raise automation rate! 3, numerical control system suits a machine tool according to needing actually to choose commonly noumenal system (be like: The KND of Japanese FANUC, Beijing) , add outfit machine tool to reached journey spacing switch at 0 o'clock. 4, V2 parameter setting: The imitate signal that CTP5 = 1 of general use of P3 = 0 of control of general vector of P2 = 1 runs to control frequency of P6 = 2 to go up by TM2 by exterior instruction gives P21 = 10 to quicken P86~P90 of time of slowdown of time P22 = 5 to teach oneself be used to according to P91 = 1 of parameter of motor parameter set frequency of carrier wave of P117 = 8 5, last word article is with vector transducer exemple, showed vector controller adequately good to torsion pilot when low frequency performance.
