Regardless of whether the manufacturer maintains and maintains the machinery after-sales, whether it is new or old customers, they must pay attention to the maintenance and maintenance of the equipment. No matter how good the equipment does not know how to maintain and repair, the life of the equipment will never be large.


This is the first stage of troubleshooting and is a very critical stage. The main tasks should be as follows:


1 Inquiring into the investigation When receiving the information on the machine site where the fault is required to be eliminated, the operator should first be required to maintain the on-site fault state as much as possible, without any treatment, which is beneficial to quickly and accurately analyze the cause of the fault. At the same time, carefully inquire about the fault indication situation, the fault appearance and the background of the fault, and make a preliminary judgment in order to determine the tools, instruments, drawings and materials, spare parts, etc. that should be carried on the site to reduce the round-trip time.


2 On-site inspection After arriving at the scene, first verify the accuracy and completeness of the various conditions provided by the operator to verify the accuracy of the preliminary judgment. Due to the level of the operator, there are many cases where the fault condition is unclear or even completely inaccurate. Therefore, after going to the scene, do not rush to handle it, and re-examine the situation carefully to avoid damage to the scene and increase the difficulty of troubleshooting.


3 Fault Analysis According to the known fault conditions, the fault classification is analyzed according to the fault classification method described in the previous section to determine the troubleshooting principle. Since most faults are indicated, in general, the CNC machining system diagnostic manual and instruction manual for the machine tool can be used to list the various possible causes of the fault.


4 Determining the cause Check the various possible causes to find out the real cause of the fault. At this time, the maintenance personnel is a comprehensive test of the familiarity, knowledge level, practical experience and analytical judgment of the machine.


5 troubleshooting methods for troubleshooting may be very simple, some faults are often complicated, and a series of preparations are needed, such as preparation of tools and meters, partial disassembly, repair of components, procurement of components, and even platooning. Therefore, the formulation of the planning steps and so on.

Whether the manufacturer for after-sales maintenance and maintenance of machinery, whether it is new or old customers for their own maintenance and maintenance of equipment, must pay attention to their own, no matter how good equipment do not know maintenance and maintenance, equipment life will never be big.

This is the first stage of troubleshooting. It is a crucial stage. The following tasks should be done:

(1) When inquiring and investigating, when receiving the information of troubleshooting in the machine tool field, the operator should be asked to keep the fault status as far as possible and not to do any treatment, so as to analyze the cause of the fault quickly and accurately. At the same time, the fault indication, fault appearances and the background of the fault are carefully inquired, and a preliminary judgment is made on the basis of which, in order to determine the tools, instruments, drawings and spare parts that should be carried by the site troubleshooting, and to reduce the round-trip time.

After the on-site inspection arrives at the scene, the accuracy and completeness of various situations provided by the operator should be verified first, so as to verify the accuracy of the preliminary judgment. Due to the operator’s level, there are many cases of unclear or even completely inaccurate description of the fault situation, so after arriving at the scene still do not rush to deal with, re-careful investigation of various situations, so as not to damage the scene, making troubleshooting more difficult.

(3) Fault analysis according to the known fault status according to the fault classification method described in the preceding section to analyze the fault type, so as to determine the principle of troubleshooting. Because most of the faults are indicated, it is generally possible to list the possible causes of the faults by comparing the diagnostic manuals and instructions of the CNC system matched with the machine tools.

(4) Determine the cause and find out the real cause of the fault through the investigation of various possible causes. At this time, the maintenance personnel is a comprehensive test of the machine tool’s familiarity, knowledge level, practical experience and ability to analyze and judge.

_Troubleshooting methods for troubleshooting preparation may be simple, and some faults are often more complex, requiring a series of preparatory work, such as the preparation of tools and meters, partial disassembly, repair of parts, procurement of components and even troubleshooting planning steps and so on.
