The numerical control lathe is a kind of automatic machine tool with high efficiency and high precision, and is also a kind of automatic machine tool equipped with a programmed control system. This control system can logically process a program specified by the control code and other symbolic instructions, and decode it, so that the machine tool can act and add parts. At the same time, CNC lathe has a wide range of process performance, can process linear cylinder, oblique cylinder, various threads and arcs, has linear interpolation, arc interpolation and other compensation functions, and can also play a good economic benefit in complex parts processing mass production operations.
So what problems should be considered when purchasing CNC lathes from machine tool factories? The selection shall be made according to the following aspects for reference only.
1. First of all, it is necessary to determine the processing process requirements of typical parts and the batch of workpieces to be processed, and then determine what functions the CNC machine tool should have. This is the work that must be prepared in the early stage. The processing process requirements of typical parts should be met under the premise of scientific and reasonable selection of CNC machine tools. The processing requirements for typical parts mainly refer to the structural dimensions, accuracy requirements and processing range of the parts. According to the specific requirements of machining accuracy, that is, the requirements of dimensional accuracy, positioning accuracy and surface roughness of the workpiece, the control accuracy of CNC machine tools is selected. It is necessary to choose according to reliability, which is the guarantee of improving the quality of machined workpieces and production efficiency. For the reliability of CNC machine tools, it usually refers to the continuous and stable operation of the machine tool for a long time without failure when it performs its functions under specified conditions. That is to say, the mean time between failures is long, even if there is a failure, it can be repaired in a short time and put back into use. It is necessary to choose a machine tool with reasonable structure, excellent production and mass production. Generally speaking, the more users, the higher the reliability of the CNC system.
2. When choosing a CNC lathe, it is necessary to carefully consider the matching performance of the tools and accessories. It is very important for the accessories and spare parts of the machine tool and their supply capacity, tools, as well as CNC lathes and turning centers that have been put into production.
3, according to the performance and price to compare, need to do not waste the function, accuracy, not idle, do not choose the function that has nothing to do with their own needs.
4. Also pay attention to the identity of the control system manufacturers, usually choose the equipment of the same manufacturer, at least the control system of the same manufacturer should be purchased, which can bring greater convenience to later maintenance. For the equipment that needs teaching, students need to be well-informed, need to choose different control systems, and need to be equipped with a variety of simulation software.
5. Attention should also be paid to the protection of CNC lathes in machine tool factories. When protection is needed, CNC lathes can be equipped with fully packaged or semi-packaged protective devices and automatic chip removal devices. Machine tool accessories are indispensable machine tool protection products, which can use the equipment for a longer time and reduce the incidence of failure.
