How to use the diagnostic method to diagnose the fault CNC lathe

Date of release:2018-01-08 00:00 Source:http://www.tianlaihe.com Click:

There are a variety of detection methods available after a problem with a CNC lathe, but in general it can be categorized into two broad categories, the first one being the detection of its system and the best way of checking under such circumstances If it is found that CNC machine problems, it immediately cut off the power, then restart the machine to see if the fault has disappeared under continuous operation or due to external forces, the lathe CNC system failure will produce lathe can not be normal Operation of the problem, and this problem is in the actual use of the lathe one of the most problematic situation.


CNC lathe manufacturers in the detection of the second product, but also more commonly used one that is the measurement diagnosis method, this method in troubleshooting more than the number of applications, mainly on the lathe hardware testing, in practice Of the testing process used in the equipment is more, for example, in the detection of hardware components when the need to use multimeter, in the detailed examination of the need to be applied to the oscilloscope and logic tester and so on equipment, with these equipment Check the various parts, and then replace the failed parts to ensure the normal use of the lathe. For the most simple example, such as the actual fault detection process, the three-phase power supply CNC system to detect, you can use the phase sequence table measurement, this measurement can be learned on the line there is a problem .


    In addition to the above detection methods, many experienced chefs in 6150 CNC lathe maintenance are also accustomed to using the principle analysis method, it can be said that the principle analysis method for fault detection has the best effect, but this approach Not every maintenance personnel can grasp, because this test method requires testing people have rich experience in the actual testing process based on their own experience and understanding of the various structural components of the lathe to analyze the crux of the problem exists where, Usually through the form of anti-push to complete the test, that is to understand the equipment in the course of the sudden failure is due to what problems occur, there is a variety of odor or unusual sound of the ring, through such an exception The performance of judging that there is a problem in that part, and then based on the principle of the various components of the lathe should be analyzed, the control of the problem causes the final solution to the problem. For example, in the use of CNC lathe thread processing when the phenomenon of random teeth, this time can be based on the basic principles of numerical control system analysis and judgment, the general emergence of such failures are due to the rotary encoder problems, this time Whenever a rotary encoder is detected, the problem will be detected as soon as it becomes available, and if there is not a problem with this component, messy appearance on the machine can only be the cause of the loss of the feedback signal, at which point The reasons for the loss of the feedback signal were investigated, after troubleshooting most of the time will find pulse encoder problems, its dismantling replacement problem will be the perfect solution. Overall, this troubleshooting is more to see the experience of the testers are rich, experienced testers, for a thorough understanding of the principle of the device, then the detection speed will be faster, but the effect will be more ideal.
