CNC machine tools on-site maintenance
Lubrication, maintenance, rational use and norms system, CNC machine tools is the main content. CNC machine tool operators the quality of technical operations, as well as the quality of lubrication failure affecting an important factor in the frequency.
CNC operators to be trained to the principle of the machine, performance, lubricating parts and carry out a more systematic study, in order to better lay the foundation for the use of machine tools. At the same time, the use of CNC machine tools and management, developing a series of practical, effective measures. Responsibility to make clear to the operator I, and directly linked to economic interests. For every accident, from the director of the Organization in charge of equipment, equipment, and maintenance personnel, technical backbone for the accident, such as analysis of the major parties and non-primary responsibility for and carry out remedial maintenance work to ensure that does not affect the progress of normal production. Criticism of those responsible for education, and in accordance with the factory, "the means of production claims for damage to non-normal approach" to a certain level of economic punishment. Of course, not an end of economic sanctions, mainly caused by the responsible party in order to attach great importance to the accident and no longer make the same mistake. Errors in the event of an accident or operation is not terrible, the key is how to learn from failure.
Stressed procedures, to strengthen the day-to-day maintenance of equipment, numerical control machine tool is another important element of management. Require the operator day look at the record before, and then check for anomalies, the observation equipment, automatic lubrication oil deficit is me, and then manually add the oil several times. Under normal circumstances, a few seconds, the machine should have the rail lubricating oil flow out, and then manual to the other parts of machine tools, accessories, such as oiling hole, especially the hydraulic chuck and the center of the piston connecting rod types of components, such as the long period of time, without maintenance, it may not be able to further adjust the clamping itinerary. Desk-type knife parts, screw holes, water holes, easy to plot a number of iron filings to stay only a few days of effective intervention efforts will stick to clear up quite cumbersome, these things with cutting fluid mixed prone to oxidation, corrosion and so on. If every day to clean up the debris, it will save a lot of trouble. Equipment in particular, are spins knife Taiwan lifted, clamping down in place after the reversal, the most easy to clean up the iron filings are not timely card inside, resulting in a knife or knife clamping Taiwan and Taiwan can not be correct, and have a feedback function of alarm the equipment will report to the police. Quite a substantial number of numerical control equipment, does not have this function roll forming machine, even though Taiwan is not in place knife, the procedure will work in accordance with the instructions of the processing campaign. Scrapped parts caused by light, heavy knife from Taiwan will be hit or chuck on the workpiece.
A, CK3263 dead Institute of Hydraulic Tailstock
1. Reasons. Operator of poor maintenance, bad lubrication; End cover seal well, into the cast iron chip and cutting fluid, so that corrosion sleeve; End unused body longer.
2. Responsibility. Operator maintenance of equipment lubrication adverse End.
3. To deal with. When dealing with this incident, the operator to take criticism and education, their learning equipment maintenance knowledge; to the operator a certain degree of economic sanctions;publication should draw lessons from other operators.
4. Preventive measures. There are no CNC equipment for the automatic lubrication device accessories, ensure that daily manual lubrication oil, check the sealing device, to take some special means to avoid the iron and into the cutting fluid. A longer period of time when not in use, it is necessary to make their activities regularly and do a good job working lubrication.
Second, FANUC-OTE-A2 automatic CNC lathe lubrication disappear
1. Reasons. CNC automatic lathe lubricating system of shunt valve failure caused by rail can not be self-lubricating, as found in time, temporary use of artificial lubrication of the guide, it did not result in serious consequences. Automatic lubrication pump oil after the tank is filled, you can use a week or so, the work of cutting fluid used in spray rails, it is not easy to distinguish whether rail lubrication fully, so that self-lubricating, once broken, it will possibly lead to a longer period of time the phenomenon of dry grinding of rails.
2. Measures. Boot and check the operation of attention.
In addition, the CK7815 and FANUC-OTD and equipment OTE-A2, the End of a body can be before and after oblique sliding rail, depending on the length of the adjustment processing parts and the distance between the spindle. Tailstock operators only pay attention to the neglect of its own lubrication guide the tailstock where the work of cleaning and lubrication. Over time, rail stations and between the end of extrusion on the dirt, not only move up easily, but also a serious departure from the Center for End spindle centerline. Processing errors caused by light, and re-create the end of Taiwan and the main fault.
To sum up, equipment management, maintenance, lubrication doing good or bad, is directly related to the vital interests of the operator and the factory's production. Therefore, the management of CNC machine tools from the start bit roll forming machine by bit, from the little things. The operator should be careful to take care of equipment, the return will be huge.
