Transducer is online the application on cut machine

25 ～ 0.

When 63 μ M, cut speed is 20mm2/min. Ra is exterior surface roughness 2.

5 ～ 1.

When 25 μ M, cut speed is 40mm2/min. The treatment of entry and law of check proved recipe are concerned in pressing GB GB7926-87, when cut anise workpiece, its even if the dimension difference of section plane is 0.

006mm, the dimension difference of cross section is 0.

009mm. The position error that processes 4 aperture is 0.

008mm, the on size error of 4 aperture is 0.

012mm. Machine tool of due and efficient cut provides an user, top speed achieves 250mm2/min. The quota of above is current commercial to becoming take machine tool of silk thread cut quickly (or by current treatment technique) will tell, be achieved hard almost and come true. Accordingly, in last few years the new technology that machine tool of domestic line cut makes an industry begin exploration to raise line cut machine tool to machine precision and new technology. Appeared to walk along silk quickly for many times early or late cut, medium take many file fast for many times silk of cut, don't go yet for many times cut, into 3 remove 2 reciprocating type the new technology such as carry silk and technology. The course of manufacturer of machine tool production that executes GB individually relapses the machining error requirement that before experiment and test and verify 3 kinds of craft can satisfy GB GB7926-87. In the repetition that solved a machine tool the guide pulley on fixed position precision and machinery shakes, Chu Si canister silk of jumpy, electrode shakes after waiting for a problem, the treatment precision of the machine tool can be rivalled with entrance machine tool. Into the 3 treatment that cancel cut of 2 reciprocating type precision also is compared common the treatment precision that takes filar machine tool quickly had very big promotion. The implementation of the technology with new above and craft raised a lot of new requirements to the control of carry silk electromotor. If speed is adjustable, much archives fast move, into 3 retreat 2, electric machinery is frequent inverting, electric machinery is fast the requirement such as apply the brake. Before support the inverting of silicon controlled rectifier that takes filar machine tool quickly and electroanalysis d.c.braking of capacitance switch circuit is to cannot realize afore-mentioned functions. Transducer of cut of fast Lei line: The special application for industry of machine tool of cut of contented eye front asks, electric limited company passes fast Lei the market survey of a few months, constituent research and development line cut machine tool is special transducer. We already were in company of production of machine tool of cut of line of Home Su Zhong much, silk goes in reaching electronic-controlled the system makes manufacturer batch use line cut machine tool special transducer. Through relapsing the experiment was satisfied completely already go quickly silk, medium to take silk, much file fast carry silk, ask into the 3 use that retreat frequent and 2 carry silk, fast apply the brake, fast inverting, transducer work is steady, the breakdown of carry silk system of the machine tool is reduced greatly. It is machine tool of cut of line of electric to fast Lei limited company below special transducer is special the simple introduction of function and characteristic: Because take filar machine tool quickly,have rapid cutting rate, use accurate repetition locates and the treatment that comparatives with silk of don't go yet is had after the treatment craft of cut for many times precision, and the fault rate of the inverting circuit of the line cut machine tool that did not install transducer and circuit of apply the brake is higher. So we are developing line cut special transducer when retained the function that takes silk quickly. Because the speed of transducer is adjustable, the carry silk speed to the machine tool has the treatment precision that applies transducer at walking along machine tool of silk thread cut quickly to be able to be aimed at to differ so and cutting rate adjust, the size range of pipe bent of the machine tool is wider. The output frequency of transducer can adjust 50HZ above, when rate can move than labour frequency at least, the carry silk of such line cut machine tools raises 20% above, the treatment speed of the machine tool can get bigger rise. In side of machine tool distribution, special transducer is in line cut machine tool electric control respect is height is compositive. The electric installation of manufacturer of this prototype bed in the machine tool respect with respect to leave out a few fault rate are higher parts of an apparatus of switch of relay, contactor, silicon controlled rectifier, electroanalysis circuit and the parts of an apparatus such as capacitance d.c.braking circuit, the electric stability of the machine tool can get very big rise, the electric layout of the machine tool is simpler also, convenient at the same time. Transducer commands a respect, can pass transducer " target frequency " or call " digital set frequency " parameter has set to the working frequency of transducer, the ascendant key that also can pass transducer, drop key or frequency set potentiometer have frequency set. Fast Lei is electric machine tool of cut of limited company line is special transducer function: Silk of reciprocating type carry. The frequency with potentiometer set does transducer to turning X second, invert the positive and negative of Y second turns automatic switch moves. Much archives fast carry silk. The much file that signature of switch of 3 when offer by system of line cut numerical control pulse that dial a code uses transducer fast undertake for many times machining to workpiece. When terminal of the TA of transducer, TC is carrying filar speed reachs stable traversal speed, put through ignition spends report of high frequency pulse; Receive when transducer stop machine signal or breakpoint scintilla pulse is cut when inverting signal high frequency report. Connect to reference point scintilla since, igneous function. Stop in transducer machine (when molybdenum silk halts use) , the transducer when the machine tool machines an end automatically to stop machine or machine tool job to break phone has function of apply the brake. This function can replace the unit of apply the brake of silicon controlled rectifier in the line cut machine tool that did not use transducer, effect of apply the brake is better. Have all the switch terminal of fast carry silk and silk of much archives carry and silk of reciprocating type carry, can be in expediently all fast carry silk and much archives undertake switch between fast carry silk and silk of reciprocating type carry.
