Change about numerical control of grinder of the channel inside 3MZ1310A upgrade transformed circumstance explains

7 inches of F940GOT) , source of communication servo drive (MR-J2S-200A) , deserve to have the communication servo electric machinery that brings 17 photoelectricity coder (HC-SFS201) etc make half closed circuit electric control system. Now I before transforming, introduce with the circumstance after transforming: One, transform around to machine precision to be opposite relatively before transforming: Dimension spends dispersedly: ± 0.

After 010mm transforms: Dimension spends dispersedly: ± 0.

003mm 　 circularity: 0.

003mm circularity: 0.

Variation of 002mm 　 diameter: 0.

004mm diameter variation: 0.

003mm 　 surface roughness: Ra0.

40 μ surface roughness: Ra0.

Actual measurement of 32 μ 　 achieves P5 class precision completely. Precision of the treatment after clearly is transformed has rise apparently, can use at precision to process more accurate product, of the class that be like P5. 2, transform around electric, mechanical part compares electric share: What before transforming, use is EX40 but program controller, periphery is electric circuit is more complex, the fault rate of together with EX40 is higher, it is more difficult to be safeguarded so; Screen of electric machinery of source of drive of module of the program controller that after transforming, component of electric control body all uses 3 water chestnut of Japanese to produce, fixed position, servo, servo, feeling makes place of half closed circuit feedback link, whole system work is steady, periphery is electric circuit is simpler, contain show through touching screen from diagnostic system, be clear at a glance, maintenance technician can undertake maintaining according to showing breakdown hints, save maintenance time greatly, improve manufacturing efficiency. Mechanical part: The feed before transforming, compensation, manipulator, nap implement, jump to introduce hydraulic pressure drive, everybody knows stability of hydraulic pressure system is poor, location is not exact, still put in leakage oily phenomenon, it is very difficult to safeguard and maintain, fault rate is frequent, the labor strength of benchwork is great. The feed after transforming, compensation, jump to use to adjust safeguard guide screw of very easy and simple ball of positive and negative, said to simplify from rigid structure the feed orgnaization of system of primary hydraulic pressure and compensation orgnaization. Machine tool precision and the stability that process work rise greatly, whole machine tool is original 7 electromagnetism a powerful person, now only remnant 4 electromagnetism a powerful person. Have a board of a powerful person only, maintenance quantity is reduced apparently. And safeguard much more convenient. 3, choose 3 water chestnut the reason 　 of electric control system 1. The history that because of Japan product of company of 3 water chestnut uses in our country is longer, control person is more, tall, stability compares credit reliable; 2. Company of 3 water chestnut but program controller programming language is straightaway, can use echelon scheme pattern to write a program, go to the lavatory simply, read easily, the person that does not have process designing experience is in OK control inside short time, with other of a few companies but program controller is compared, can reduce the time that reads echelon figure, improve the maintenance efficiency of maintenance technician. Additional, still can use line and modulation section air implement undertake be debugged remotely and be maintaininged, can undertake modification to the program of the user, diagnostic breakdown, can shorten maintenance, diagnose, debug time and economic force poor expenses. 3. The photoelectricity coder on electric machinery of servo of company of 3 water chestnut is 17 (217) than OMRON company (215) many, grating resolution raised 4 times. Locate unit module can undertake process designing of numerical control type, improved process designing efficiency greatly, simplified program structure. 4. Use color to feel screen set parameter and state of indication data, job, monitoring, call the police etc, man-machine interaction goes to the lavatory simply, make operate more human nature is changed. 5. Look from function, the use function of the system of 3 water chestnut that uses on 3MZ1310A and OMRONC200HE is same, but system of control of on the price 3 water chestnut has clear price advantage, sexual price is compared tall. Additional, the product of company of 3 water chestnut already was in course of study of one's own profession applies in great quantities, a lot of equipment manufacturer already used system of 3 water chestnut gradually or replaced ohmic dragon system completely. 4, before adjusting a respect to transform: Need adjusts hydraulic pressure pressure, rate repeatedly according to the experience of handlers, temperature change impact is very big, differ to fluctuation midday very; After transforming: Passing feeling screen to input all sorts of speed, feed is the certain value of digitlization, do not appear unusual appearance, it is changeless commonly, operate simplification, master easily, feed machinery needs to adjust scarcely partly, reduce auxiliary time and breakdown time greatly, raised a machine tool significant handling time, reduced maintenance cost. 5, the new numerical control 3MK1310A that transforms overhaul charge respect to purchase a same configuration needs many yuan 20, numerical control is changed transform include to heavy repair a need 11.

50 thousand yuan (treatment precision and efficiency are close to new machine tool) , 57 what be equivalent to purchasing new facility value only.

5% , purchase 10 to mix transform overhaul 10 photographs are compared, purchase new 3MK1310A, 10 need many yuan 200, transform overhaul 3MZ1310A10 stage to need 1.15 million yuan, used 850 thousand yuan less, 850 thousand yuan still transform overhaul quite 7 same equipment, if his monthly wages 1000 yuan, the salary that opens a month to 850 people quite. Via breathing out ministry of axial strategy program, finished product 3 minutes special device combines bearing of factory, Shijiazhuang parameter of processing technique of the equipment precision after company collective test transforms overhaul, machine tool, compare with photograph of parameter of the precision of new facility, processing technique, the result is almost same, because transform the waits for precision of influence machine tool to feed orgnaization, compensation orgnaization, main shaft component when upgrading to undertake updating entirely almost, manipulator, nap implement the part with not large to precision influence part did not change but changed bearing and fragile, treatment is compared with the photograph before transforming after transforming respect of precision, performance characteristics is having clear improvement. Stability rose, stop chance is little repair a frequency to decrease, work efficiency rose. 6, on economic benefits and social benefit although transform around class crop to be in 1600 / every or so, but production value is different, the price that tastes commonly and P5 photograph compare a difference very big, can do the product of high additional cost, enhance the competition ability of the market, the action with big due on international bearing market company of sufficient play collectivize. Altogether, making counting accusing to change a technology to upgrade transform is class of hoist of state-owned old company, dig old equipment latent capacity, beautiful money is scarce a shortcut with fast effect, to raising the economic benefits of the enterprise, managing to building circular economy model the society is well worth doing, it is the only way that mends technical reformation of state-owned old company.
