The application of PLC in the numerical control transformation of lathe (3)

5 Conclusion

The application of CNC lathes in China's machinery manufacturing industry is developing rapidly, but high-precision CNC machine tools are expensive, and there are a large number of parts with less complicated shapes and high precision requirements in actual production. This requires high-precision CNC lathe machining. At the same time, there are a large number of common lathes available in China. The numerical control of these lathes is an effective way to increase production efficiency and improve efficiency with less investment. In the past, the numerical control transformation of the lathe was carried out by using the Z80 and 8031 ​​chips as the core components of the numerical control system. The price was relatively expensive and the system was complicated. The numerical control system using PLC as a lathe has the advantages of low cost, simple system and convenient adjustment, and will be widely used.
