Program and Necessity of Rebuilding CNC Machine Tools

Date of release:2017-12-19 00:00 Source:http://www.tianlaihe.com Click:

In recent years, China's machine tool industry, rapid economic growth, the production of CNC machine tools rate has improved. However, there are more than 4 million kinds of common machine tools in our country. Among them, one-fourth of the machine tools have a service life of more than 30 years. These machines have no value in reconstruction and need to be eliminated. The remaining about 70% of the machine tools can be digitally controlled . The implementation of many ordinary machine tools to transform and update the formation of hundreds of billions of new market demand, to maintain economic growth can play a role. Therefore, numerical control transformation project can form hundreds of billions of industrial added value.




First, CNC machine tools to determine the transformation program


On the basis of the machine tool mapping, according to the user's requirements, to determine the overall machine tool transformation program.


1, CNC system transformation program


2, spindle servo system transformation program


3, feed servo system transformation program


4, closed-loop control testing device transformation program


The company is located in:


    Second, the need to transform the status of the machine tool to investigate


Not all of the old machines are suitable for CNC transformation, the need to transform the machine to conduct a comprehensive understanding.


The mechanical system of the machine to conduct the mapping to make the right judgments, good mechanical performance is the basis for the successful transformation of CNC machine tools, otherwise no matter how good the CNC system can not play its due performance. Therefore, in the transformation of CNC machine tools to deal with the machine before the detection of mechanical precision and found that the problem can be carried out in the process of machine tool repair and repair. If there are many problems with the machine tool system, such as the old machine tool in the mechanical structure design, manufacturing defects, CNC machine tool transformation will not have much significance.


The old machine electrical system due to aging components constantly, is the focus of machine transformation. To understand the old machine tool manufacturers NC model number, the number of control axes, spindle, feed axis drive configuration, spindle motor power, feed axis motor torque and so on.


Check the random technical information is complete and complete, complete technical information to shorten the technical preparation of machine tool transformation time. One of the electrical schematics, PLC program, machine maintenance manuals, hydraulic, pneumatic, lubrication schematic, mechanical assembly plans, we have to study carefully. Special attention should be given to the technical information provided by the content may be wrong, does not match with the machine tool. This is because some machine tool manufacturers provide a series of models of general drawings, electrical hardware changes in individual machine is not marked on the electrical data, which requires that we must control the machine in kind, carefully check and avoid errors.




Three, CNC machine tools to transform and update the cost-effective analysis


The old machine in the NC transformation, the market should investigate the same price of CNC machine tools. The price comparison of the two should also consider delivery time. For the price is not high of small CNC cars, milling machines, it is recommended to purchase new machines updated, do not carry out the transformation of the old machine. Because the cost of both is about the same, saving less money, machine transformation time is about 2 months. For small CNC cars, milling machines, machine tool manufacturers generally have the spot. For large, more expensive CNC machine tools to transform is a better choice, not only can save more money, you can also shorten the purchase time. For example, a table size of 2000 × 1800mm, three-axis linkage, horizontal machining center of 60 tools control as follows.




    According to the experience of transformation in the past, the common CNC machine transformation, the machine efficiency has improved significantly. The original one machine needs a person control, after the transformation of a worker can control two machines at the same time. At the same time, the machining accuracy of the machine tool has been greatly improved, and the rejection rate caused by human error has been significantly reduced. At the same time, the labor intensity of workers is reduced, the labor force is saved, the trial period and production cycle of new products are shortened, and enormous economic benefits are brought to the enterprise.
