CNC lathe staff professional skills

is a noticeable phenomenon of CNC lathe users than ever, but the use of the machine rate is not high, of course, sometimes produce task is not full, but there is a more critical factor is not high, CNC operator nature met some problems do not know how to deal with, especially the new machine, because of the quality problem of the electronic components, and transport by the vibration of the factors, such as CNC system went into operation in 3 ~ 6 months show some trouble phenomenon, often is not in the repair manual, or perhaps have never encountered, which requires the person that use is of high essence, can treat problems, calm mind, discriminant ability is strong, the scene of course should also has the advantage of the relatively thick foundation, etc. The use of numerical control lathe is bigger than the difficulty of the use of general machine tools, because the CNC lathe is a typical electromechanical integration products, it involves a wide range of knowledge, namely the operator should have machine, electricity, liquid, gas, etc. The wider professional knowledge, so the nature of the request is very high to operating personnel. CNC lathe trouble: a, the host fault diagnosis on common host fault, diagnosis method, such as using advanced testing means 'modern diagnosis skills' and the traditional 'useful diagnosis skills', etc. 1, useful skills, the diagnosis is confirmed by protecting personnel after their sense organs and experience for nc machine tool fault diagnosis. Use useful skills diagnosis confirmed process owing to the different fault types, all kinds of way, then can be interspersed with or take part in, should be inductive analysis, can get better effect. Clutter valuable instruments useful diagnosis skills don't demand, can be diagnosed, anywhere, anytime and quickly, fast, high accuracy, especially suitable for preliminary diagnosis of machine tool. 2, modern skills, the diagnosis is confirmed diagnosis instrument and data processing is used to machine some characteristic parameters of the mechanical equipment, such as vibration, noise and temperature measurement, the measurement value compared with the normal rules for judging mechanical equipment operation condition is normal, then the operational condition of mechanical equipment in prediction and forecast; And to the machinery may be further trouble reason, position and extent of the trouble for the qualitative and quantitative analysis. Using the modern diagnosis skills but in the early stages of the mechanical equipment attack problems, found that part of the trouble in time, and to protect, then can avoid further damage of mechanical parts. Modern diagnosis skills has now got the promotion and application. Second, the electrical system fault diagnosis of the electrical system in the numerical control lathe, the query, analysis and the fault diagnosis process, also is ruled out of the trouble process, so the fault diagnosis method is particularly important. Here briefly introduces some commonly used diagnosis methods. 1, intuitive method. First choose visual, touch, electricity, etc. Repair personnel in the trouble diagnosis when first using the method is intuitive to check. First consultation, to the present problems of specific consulting field personnel problems have happened, the fault phenomena and fault consequences, and in the process of the whole analysis, discriminant repeated inquiries; The second is examined, based on the principles of fault diagnosis from inside extroversion of illness gradually. All the check machine electric control equipment ( Such as smooth equipment, numerical control system, temperature control equipment, etc. ) Whether the presence of alarm indication, operation condition of the parts are in normal condition, For mechanical bearing, spindle, the coordinate azimuth, knife library, etc. ) On printed circuit boards, machine is local to investigate whether there is a short circuit, open circuit, the circuit components and whether there is the phenomenon such as cracks, burns, whether the phenomenon such as poor contact, the repaired PCB, more to see the shape, the wrong parts and wire, and so on and so forth; The third is the contact, under the condition of the machine power can through the contact of the primary circuit board installation situation and situation of each connector plug, the power and signal wire ( Such as servo motor contactor connection) A join condition, etc. To find out why may present problems. 2, since the diagnosis function method. Using numerical control system since the diagnosis function, alarm information, indicates the general problem. 3, exchange method. The same module and unit exchange, investigating fault handling, then quickly identify the part of the problem. 4, instrument measurement comparison method. When fault system attack, choose conventional electrical testing instruments, the fault part was measured, such as voltage, power supply, pulse signal will be in comparison with the values of normal and fault, to be able to split out the problem and the cause of their positions.
