The head wears controller of system of numerical control of grinder of keyword nicety whorl grinder of whorl of semi-automatic nicety of SB7320 of 　 of 　 of Use SKY NC System For Retrofitting Precision Thread GrinderYin Yanchi, it is factory of Hanjiang machine tool 70 time end is what plant design makes steering gear of group of leap forward automobile, the accurate whorl grinding machine that is used technically at machining screw of ball of car direction machine, it is one of crucial equipment of this factory. This machine tool uses the numerical control system that the logistic circuit that comprises with the component that be not the door and sequential circuit make, the printed circuit in numerical control ark board amount to more than 50; The imitate enlarge circuit that the drive circuit that 3 paces enter electric machinery is high-power dynatron composition; Data uses 8 or two dial and 8 key-press input; Machine tool control is the programme controll circuit that relay, contactor makes partly. The circuitry of the machine tool is complex, dependability is poor, maintenance is difficult. This grinder passes use of ten years, the system is backward already, breakdown frequency is tall. My factory undertook transforming to grinder of this numerical control 1995. If the numerical control system of the machine tool is used at that time system of domestic economy numerical control, it is to use veneer machine to decide charge unit, i/O mouth amount is very few, and process designing is trivaller also, cannot get used to the requirement of this machine tool. If the price with system of FANUC, SIEMENS is very high. And the system of SKY numerical control that limited company of company of Nanjing quarto electron develops, come true on common computer platform. It uses 32 80386CPU, the hard disk that deserves to have 270M above, 1.

44M soft drive and 14 inches of colour are shown, the computer with the one whole a complete set of such as use standard clavier serves as advocate charge unit, i/O mouth amount also can satisfy the requirement of different programmed control. In the machine tool the Yi Ke when working makes common computer use. Drive component can be servo electric machinery or pace enter electric machinery, work of numerical control system operates platform to go up in UCDOS Chinese character, can achieve two axes or 3 axes linkage. Although its price is a bit some more expensive than common economy numerical control, but 3 performance/price ratio is system of general economy numerical control.

5 times above. System of SKY numerical control strings together a mouth with the COM1 of computer or string together mouth and outside patulously to have news report, i/O communication mouth satisfies our use completely. The F1 that we use 3 water chestnut companies of Japanese to produce, the controller that MR60 can make up Cheng controller and F1-ER60 to expand unit serves as a machine tool. The communication between PLC and NC shares 30, by two serial mouth is finished. The execution of numerical control program undertakes below PLC programme controll, included completely the function with original machine tool and mode of operation. To get used to the mode of operation of primary machine tool and function, the means of numerical control process designing that we use, be like the method that uses R parameter process designing together, all instead is in the mode of operation of data of numerical control of input of the dial primary machine tool, key-press on the screen of Chinese character operation of numerical control system, install / choice parameter and choice mode of operation. We an all operation simplification, switch on the mobile phone to enter systematic initialization state namely, the operation that can choose a machine tool according to showing the hint on screen shows interface or interface of machine tool job. In operation specification interface, we wove the machine tool uses the operation method of system of SKY numerical control and safe operating rules. In interface of machine tool job, we work the grinding of the machine tool means (the hand is moved / automatic, one-way grinding / two-way grinding, kibble / half essence is ground / essence of life is ground) , grinding circulation time, means of emery wheel nap (the hand is moved / automatic) , kibble, essence grinds feed, the parameter such as frequency of emery wheel nap and nap quantity uses menu to list on screen one by one, cursor key of the ↑ that uses clavier to go up only, ↓ , ← , → undertakes choose and be modificationed. Still show on screen workpiece machines the dynamic dimension when at the same time. The drive component of numerical control system is 3 paces enter electric machinery, namely: Nap of electric machinery of emery wheel feed, emery wheel implement feed electric machinery and electric machinery of compensation of clearance of lever of workbench drive silk. The pace uses clench the teeth of a pair of gear into electric machinery and lever of transmission ball silk. Among them, passive gear uses the gear of facewidth of driving gear of a pair of 1/2 to be folded, two gear produce certain amlposition part with bedspring, can eliminate automatically advocate, the clearance of clench the teeth of passive gear. The head of the machine tool wears rotational dc electric machinery to convert three-phase asynchronous electric machinery, with Japan frequency control system undertakes 3 water chestnut communication stepless speed regulation. Because electric machinery and head wear an axis to use leather belt connection, according to the rotate speed limits that the machine tool works, choose appropriate drive to compare, make electric machinery job is between 25 ～ 60Hz, the physical characteristic with made sure the head wears electric machinery to have better and the good character that start. When the machine tool works, the roll that the head wears is changeless, the adjustment of its speed uses reason only timing potentiometer is adjusted. Because difference of dimension of work semifinished product is bigger, older to partial dimension work semifinished product must use a hand to move grinding, withheld a hand to move grinding so. When the hand is moved, outside moving emery wheel feed except the hand, the nap of emery wheel and compensation of clearance of workbench silk lever still are pressed beforehand the quantity of buy is automatic feed. To ensure the safety of the machine tool is operated, we installed safe protection system to reach interrupt a function compulsively. If need to suspend a program,move in grinding, handlers should press only " emery wheel is regressive " pushbutton, emery wheel backs down quickly and break down program. Handlers presses " Esc " key, quit numerical control system. The machine tool is in " the hand is moved adjust " below means, after undertaking necessary adjustment, make the machine tool is in grinding initiative condition. Key in " 7320 " after file name, enter afresh " automatic grinding " condition continues to work. The 30 communication signal between PLC and NC, in debug or be maintained, can examine with DEBUG statement on the computer of numerical control system data news report is correct, brought to maintenance convenient. Consign used this machine tool in April 1995 up to now. CNC Milling CNC Machining
