CNC machine tool is the product of the comprehensive application of computer, automatic control, automatic detection, precision machiner,y, and other high and new technologies.

 

It is typical mechatronic processing equipment with high technology intensity and automation. Compared with ordinary machine tools, it not only has high machining accuracy, and stable product quality, but also has a very high degree of automation, which can reduce the physical labor intensity of workers and greatly improve the production efficiency. It can also complete the machining of parts with complex curved surfaces that are difficult or impossible to machine by ordinary machine tools. Therefore, the position of NC machine tools in the machinery manufacturing industry is becoming more and more important. However, we should be soberly aware that whether the above advantages of CNC machine tools can be achieved depends on whether the operators can properly and correctly use them in production.

From the perspective of the operator, let's talk about the matters needing attention in the use of CNC machine tools to ensure that the advantages of CNC machine tools can be brought into full play.

 

  1. improve the comprehensive quality of operators

 

The use of CNC machine tools is more difficult than that of ordinary machine tool because CNC machine tools are typical mechatronics products, which involve a wide range of knowledge, that is, the operator should have a broader professional knowledge of organic, electrical, hydraulic, gas, etc., so the quality requirements for operators are very high. At present, a phenomenon that can not be ignored is that there are more and more users of CNC machine tools, but the utilization rate of machine tools is not high. In addition to the insufficient production tasks, a more critical factor is that the quality of operators is not high enough. When encountering some problems, I do not know how to deal with them. Especially for newly purchased machine tools, due to the quality problems of electronic components and the vibration during transportation, Within 3 ~ 6 months after the formal production, the CNC system has some faults, which are often not found in the maintenance manual, or may have never been encountered before. This requires users to have high quality, be able to deal with problems calmly, have a clear mind, have strong on-site judgment ability, and have a solid CNC foundation. In general, when purchasing a new machine tool, the machine tool manufacturer will provide users with technical training opportunities. Although the time is not long, they are highly targeted. Users should pay attention to them. The personnel sent should include future machine tool operators. The improvement of the comprehensive quality of the operators is not a matter of a moment or two, but a long-term one. It should be accumulated for future use. Another way worth trying is to visit some old users of similar machine tools. They have strong practical experience and Z has the right to speak. They can ask for their help and let them carry out certain training for the operators. This is an effective way to improve the comprehensive quality of the operators in a short time.

 

  1. follow correct operating procedures

 

No matter what kind of machine tool, it has its operating procedures. It is not only one of the important measures to ensure the safety of operators, but also an important measure to ensure the safety of equipment and product quality. The user must operate correctly according to the operating procedures. If the machine tool is used for the first time or has not been used for a long time, it should be idled for a few minutes. Pay attention to the sequence and precautions of startup and shutdown during use. These should be paid enough attention to by beginners because they lack corresponding operation training and are prone to make mistakes in this regard.

 

  1. create a good environment for use

 

Generally speaking, there are no harsh requirements for the use environment of CNC machine tools, which can be placed in the same production workshop as ordinary machine tools. In spite of this, CNC machine tools contain a large number of electronic components, which are afraid of direct sunlight, humidity, dust, vibration, etc. These can cause corrosion and deterioration of electronic components or short circuits between components, resulting in abnormal operation of the machine tool. These are generally noticed when installing the machine tool. For users, it is mainly to pay attention to the protection of the surrounding environment. For example, on rainy days, they should not bring umbrellas to the production site and replace shoes.

 

  1. try to improve the starting rate of the machine tool

 

If the start-up rate is not high, it will not only make the user's investment unable to play the role of reproduction but also a worrying problem is that it is likely that due to the expiration of the warranty period, the equipment will need to pay additional maintenance costs because the newly purchased equipment has a certain warranty period. From past experience, the failure rate of CNC equipment is relatively large at the initial stage of use, Users should make full use of the machine tool during this period to expose its weak links as soon as possible and solve them within the warranty period. Usually, there is no production task, and you can't idle. This is not a love for the equipment. On the contrary, due to long-term use, the deterioration or damage of electronic components may be accelerated due to dampness and other reasons. The user shall be powered on regularly, and each time the machine runs idle for about 1 hour. The heat generated during the operation of the machine tool shall be used to remove or reduce the humidity in the machine.
