The efficient and complex automation that numerical control machine tool is unifinication of the machine with very high content of a kind of technology, report, appearance machine tool, the machine tool is in moving process, component can produce the breakdown of different level, different type inevitably, accordingly, be familiar with the feature of mechanical failure, master the commonly used method that mechanical failure of numerical control machine tool diagnoses and method, eliminate to having major effect to deciding the reason of breakdown is mixed. Diagnostic principle of breakdown of numerical control machine tool and ask system of machine tool of alleged numerical control malfunctions basically (or weigh invalidation) it is the function that shows system of numerical control machine tool lost a regulation. Breakdown can show divide into equal parts of form, property, origin to be a variety of types by the watch. But no matter type of which kinds of breakdown, when undertaking diagnostic, can abide by a few principles and diagnostic skill. The principle that discharge barrier basically includes the following fields: 1) investigates breakdown phenomenon adequately, be opposite above all the investigation of handlers, enquire the whole process of occurrence breakdown in detail, some what phenomenon arises, had adopted what measure to wait. When wanting to do meticulous survey;2) to search the origin of breakdown to the spot next, train of thought wants to widen, no matter be compositive electric equipment, still mix mechanical, hydraulic pressure, want to cause the cause of this breakdown likely only, should list in the round as far as possible come. Undertake be judged integratedly and be optimizinged choosing next, the reason;3) that produces breakdown the most likely certainly first machinery hind is electric, principle of the trends after Xian Jing condition. Before corrective maintenance, should notice to remove mechanical trouble above all. Fall in moving condition again, the observation that has trends, examine and check, search breakdown. And of ruinous to can happening after electrify breakdown, after must eliminating risk first, square but electrify. Breakdown diagnoses a requirement besides substantial professional knowledge, need has the personnel that diagnoses exercise into breakdown of travel numerical control to start work certainly ability and practice operation experience, requirement staff member combines practical experience, be good at an analysis thinking, through analysing breakdown reason to the real operation of breakdown machine tool, accomplish with changeless should 10 thousand change, achieve the result of draw inferences about other cases from one instance. Complete maintenance tool and diagnostic appearance is indispensable, commonly used tool is like screwdriver, forceps, spanner, electric iron to wait, commonly used measuring instrument is like avometer, oscillograph, signal generator to wait. Divide this beyond, the staff member still needs to prepare necessary technical data, exactly the amount accuses manual of manual of parameter of system of blueprint of principle of machine tool electric equipment, structural composition blueprint, numerical control, maintenance, installation, operation, operation instruction handbook to wait. System of different numerical control designs the train of thought that breakdown handles thought 1000 difference 10 thousand different, but no matter the sort of system, their fundamental and compose Chengdu are very similar. Because this is when machine tool occurrence breakdown, requirement maintenance technician must have the train of thought that clear breakdown handles: Survey breakdown scene, acknowledge nature of breakdown phenomenon, breakdown, answer to master breakdown information adequately, accomplish " much beat one's brains, careful start work " the broaden the scope that prevents breakdown. According to place control breakdown information makes clear the complex degree of breakdown, the full doubtful point of place of listed breakdown. Prepare necessary technical data, for instance machine tool manual, graph of electric control principle, analyse breakdown reason for the foundation with this, make the plan that removes trouble, requirement train of thought is open, should not be restricted breakdown bureau the some part at the machine tool. After plan of affirmatory trouble removal, use show avometer, oscillograph to wait measure a tool, the methodological test and verify that uses a test detects breakdown, chase place of breakdown of class fixed position, affirm a breakdown to attribute electric breakdown or mechanical failure, of the random still sex that is systematization, it is oneself breakdown or exterior breakdown are waited a moment. Of breakdown eliminate. The problem after finding breakdown reason normally is met the be readily solved on the horse. The numerical control system of machine tool of numerical control of breakdown processing technique is the core place of numerical control machine tool, its move reliably, what matter to whole equipment to move directly is normal. Summary abstraction gives a few judgement and the method that eliminate breakdown of numerical control machine tool below. 1.
Make full use of warning function of hardware of numerical control system, software. All install in system of contemporary numerical control numerous hardware calls the police demonstrative device, setting hardware calls the police to be able to safeguard a gender what demonstrative device is helpful for improving numerical control system. The system has the CNC of numerical control machine tool to diagnose a function oneself. During numerical control system works, can timely use undertake be diagnosticed quickly to the system from diagnostic program. Once detect breakdown, can stand to show trouble with the means that call the police namely go up in CRT or illume indicator light calls the police on face plate. And this kind diagnoses a function to still can call the police breakdown classification oneself. 2.
Numerical control machine tool is simple breakdown calls the police the method of processing. Normally, numerical control machine tool is had stronger from alarm function, can at any time the working status of supervisory system hardware and software, the major hitch of numerical control machine tool can appear call the police clew, can hint according to breakdown, decide the breakdown of the machine tool, seasonable processing, remove trouble, raise a machine tool serviceability rate and use efficiency.
