The high efficiency of CNC sawing machine is the development trend of sawing machine in my country
Metal sawing in the traditional sense is often regarded as a simple cutting process. As the modern manufacturing industry develops in the direction of high efficiency, high precision and economy, sawing, as the starting point of metal cutting, has become an important part of the process of parts processing. Sawing can save data, reduce the amount of secondary processing, and improve the output power. Therefore, sawing machines, especially automated sawing machines, have been widely used in various fields of the national economy such as steel, machinery, cars, shipbuilding, petroleum, mining, and aerospace.
Bow sawing machines, circular sawing machines and CNC sawing machines are the three main sawing methods, among which band sawing machines are gradually replacing traditional bow sawing machines and circular sawing machines and are beginning to dominate.
Although the history of CNC sawing machine development and coverage is relatively short, the technology has made significant progress. In the 60s of the last century, it took 15-20 minutes to intercept 150mm 45 gauge steel. Today, it only takes 1.5-2 minutes. The power has increased by 10 times in the past 30 years. Band sawing machines also have significant advantages in the utilization of data. For example, the band sawing machine can save 56% of the original data compared with the bow saw, and it can save up to 87.5% of the original data compared with the circular saw. . It can be seen that the band sawing machine has the characteristics of fast cutting speed, high scale accuracy, and small data loss. In addition, this kind of sawing machine has wide adaptability, low power consumption, simple operation, easy protection and angle cutting, so it has become more and more widely used.
Among the band sawing machines, the double-column band sawing machine has the best performance. The double-column band saw machine adopts the overall saw frame structure of double-guide column and double-hydraulic cylinder, and uses the parallel method for sawing. The rigidity is durable, which ensures the stable operation of the saw frame and improves the life of the saw band. With the rapid development of my country’s national economy in recent years, band saws have gradually begun to spread. At present, a small number of manufacturers have developed double-column band saws through technological innovation. In developed countries such as Europe and the United States, bow sawing machines have been basically screened, and band sawing machines are rapidly spreading. This trend is particularly significant in Germany. Take BEHRINGER, the world’s number one sawing machine manufacturer, as an example. It has been producing double-column band saws for more than 20 years. So far, it has developed nearly a hundred types and reached a high technical level.
