CNC machine tools and traditional machine tools have similarities in mechanical structure, but there are obvious differences in operation, accuracy, production efficiency, and degree of automation. The differences between them will be described below from the following perspectives:
1. Different operation methods
Traditional machine tool operation methods mainly rely on manual labor and manual adjustment, which requires skilled workers to master various operating skills, and the production process is relatively cumbersome. The operation of CNC machine tools is mainly realized through computer programming. Operators do not need to have much mechanical knowledge, and operating errors are avoided, and production efficiency is high. By the way, current CNC machine tools not only have industrial control hosts behind PCs, but also have advanced SIMATIC programming functions to assist operators in better achieving precise processing.
2. Different accuracy
In traditional machine tools, since the machining accuracy of the machine depends largely on the skills and experience of workers, its accuracy is relatively low and manual correction is often required. Because CNC machine tools adopt CNC systems, they can accurately control parameters such as processing position and processing depth, so they have high processing accuracy and can meet various high-precision processing requirements.
3. Different production efficiency
Due to the complex operation of traditional machine tools and the need for skilled workers to complete various tasks, production efficiency is relatively low. CNC machine tools adopt computer control and can automatically complete various operations. The production efficiency is very high and the processing cycle is short. It can shorten the production cycle of products and improve production efficiency. In addition, CNC machine tools also have the advantages of automated typesetting, clamping, processing, measurement, sorting, and discharging, thereby increasing productivity and reducing production costs.
4. Different service life
Traditional machine tools usually require frequent repairs and maintenance and have a relatively short service life. In contrast, CNC machine tools use advanced electronic control systems, which have the advantages of high stability and low error rates. Therefore, the service life is longer and the repair and maintenance work is relatively reduced. At the same time, the maintenance cycle of CNC machine tools is also very long. Apart from replacing parts that have expired, there is basically no need for any maintenance work. This not only reduces the company's operating costs, but also provides them with a longer mission.
5. Costs are different
Traditional machine tools require skilled workers and more manual operations. CNC machine tools do not require high-quality workers and can be operated and maintained by ordinary technicians. Therefore, the labor cost of CNC machine tools is lower than that of traditional machine tools. Because CNC machine tools have high processing precision, high production efficiency, and long service life, they can greatly improve production efficiency and benefits. In comparison, the cost of CNC machine tools is still relatively low.
6. Different management methods
Compared with traditional machine tools, CNC machine tools require the development of specialized management software, which is more convenient in monitoring and management, can effectively improve process quality, and has a fast, reasonable and simple management cycle. With the arrival of Industry 4.0, CNC machine tools, as important production equipment in smart factories, have further exerted their huge advantages in achieving independent tuning.
In short, compared with traditional machine tools, CNC machine tools have higher production efficiency, better precision, lower labor costs, longer service life and more convenient management methods. Therefore, in modern manufacturing, CNC machine tools have become an indispensable tool and one of the important ways for enterprises to improve production efficiency and reduce production costs.
