Can a CNC lathe replace an automatic lathe?

- Aug 22, 2018 -

      The automatic lathe originated in Germany, and later spread to Japan, and then developed to Taiwan, which has a history of more than 100 years. With the reform and opening up of mainland China, automatic lathes have been invested by Taiwanese businessmen, Hong Kong businessmen and Japanese businessmen in the mainland and developed into economically developed areas along the coast, especially in the Pearl River Delta and the Yangtze River Delta. They are slowly extending towards the Bohai Delta.

      With the trend of mainland policy and the decentralization of the national economy, so far, the automatic lathe has been developed from the original Pearl River Delta Shenzhen, Dongguan Zhongshan and the Yangtze River Delta Kunshan, Suzhou, Wujiang, Wuxi, Changzhou, to the mainland Various regions, such as Shandong, Hebei, Tianjin, Jiangxi, Hunan, Hubei and other places. According to incomplete statistics, at present, the number of automatic lathes in mainland China is about tens of thousands (including foreign purchases and movements from abroad), and the manufacturers of automatic lathes are also produced by Wang and Mingyang, which were originally only produced in Taiwan. Dozens of such companies as Shanshan, Qiaqun, Qiu Cun and Yu, have developed into nearly 20 enterprises including Mingyang, Taike, Ningjiang and Qifeng, which have been established in the mainland. The customers in the Pearl River Delta and the Yangtze River Delta are mainly based on Mingyang and Taiwanese. Because of their certain advantages in brand, quality and cost performance, they have won the trust of customers. The other brands also have their own advantages in different fields. Have their own market share.

        However, due to the limited market and the near saturation of some industries, the competition in the automatic lathe industry in mainland China is becoming increasingly fierce and the situation is ever-changing. For this reason, some manufacturers have partially transformed or introduced new models. For example, Tianjin Sipeng Automation Machinery Co., Ltd. has developed magnet punching machines, steel pipe chamfering machines and steel pipes based on the existing five-knife type 1525 and 2025. Cutting machine, CNC lathe, automatic lathe, table lathe, multi-head drilling machine, double-head milling machine, double-head chamfering machine, CNC double-head chamfering machine, CNC spiral milling machine, bar material automatic cutting machine, steel pipe cutting machine, steel pipe New models such as cutting machines, bar cutting machines, bar cutting machines, bar cutting machines, automatic instrument lathes, etc., and the company has also introduced a one-year warranty for the purchase of machinery, which has made the development of automatic lathes in mainland China. Certain contribution!

      The automatic lathe uses the PLC to control the movement of the cylinder and the cylinder or the motor. The cylinder and the cylinder or the motor push the carriage to open the workpiece. Changing the movement of the cylinder and cylinder or the motor can create different ways of moving to process different products. Because the cylinder and cylinder or motor motion is converted into intermittent motion of the mechanism, it has the advantages of high transmission sensitivity and high speed. Therefore, the automatic lathe has the advantage of high processing efficiency, and the development period is long, and it is constantly passed by various manufacturers. The newer and improved, the automatic lathe has the advantages of high processing precision and diversified functions.

      However, the advantages are often the shortcomings. The automatic lathe is suitable for the hardware products with relatively large output. Because it needs to adjust the various processes, movements, time, size, etc. of the machine, the cylinder and the cylinder or the motor drive are efficient, but because PLC control can only process the same type of products. When processing different products, it is necessary to re-create new feeding mechanism and chuck, which makes the automatic lathe versatile, and also puts forward higher technical requirements for the master who operates the automatic lathe. And the difficulty, this is also the difference between automatic lathes and other processing equipment.

      With the introduction of foreign CNC lathes, and the research and development of the original large-scale machine tool factories in China, all kinds of CNC lathes have sprung up and blossomed. Not only the variety and function, but also the traditional machine tool modification type and self-developed type, both the knife type and the heart type, both turret type and knife type, not only with the back axis type but also with the car milling compound Multi-knife simultaneous processing and so on. Looking at all types of CNC lathes, the main advantage is that the machining action can be controlled by a computer program. The operator can write the different control programs, and the microcomputer drives the servo motor to drive the screw drive to process the tool. Therefore, the machining operation mode only needs to be programmed, and the master knows The process will sharpen the knife, which is easy to operate and easy to learn. The defect is that the machining efficiency is low, because the automatic lathe can be processed at the same time with five or more knives, while the CNC lathe can only process one tool at a time, the other tools are in the waiting state, and the transmission speed of the servo motor and the screw has Intermittent time, so in terms of efficiency, CNC lathes are always better than automatic lathes.

     In summary, the two have different advantages, the automatic lathe processing efficiency is high, but the operation technology is difficult and the variability is poor. The CNC lathe can be programmed and has high variability but low processing efficiency, and no one can replace it in different processing fields. Who. In the mass production and processing of parts, automatic lathes have the main advantage, and the development trend of the existing CNC lathe can not replace the automatic lathe for at least 5-10 years, but the automatic lathe is far behind in the complicated processing and the quantity of products. The development of CNC lathes is the inevitable direction of many factories in China in the future. Throughout Japan and Taiwan, the localized processing of automatic lathes is very rare, most of which are CNC lathes. The processing of automatic lathes has basically shifted to developing and underdeveloped countries. Maybe China’s future development is almost the same.
