cnc circular saw
Cnc Circular saws, band saws and bow saws are the three main types of sawing machines. Band saws have gradually replaced bow saws and circular saws and have become the dominant trend in sawing machines. What is the reason? In terms of material utilization, band saws have obvious advantages. Band saws have fast cutting speeds, high cutting accuracy, and low material loss, which make them widely used. In developed countries such as Europe and the United States, bow saws have been basically eliminated, while band saws have quickly become popular. This trend is particularly evident in Germany. Take the German company Behringer, the world's number one sawing machine manufacturer, as an example. It has a history of more than 20 years in producing double-column band saws and has developed nearly 100 models to date, reaching a very high technical level.

Advantages of CNC sawing machines
The control interface of the fully automatic circular saw machine adopts an operating system developed based on PLC HMI technology, usually equipped with a touch screen and an operation panel. With the human-machine interface, the operator only needs to input parameters such as the material specifications and processing quantity, and the system will automatically adjust the saw blade speed, the feed amount per tooth (cutting speed) and other complex parameters according to the input parameters, so as to provide the operator with the simplest operation method. This type of circular saw machine has high safety and generally works in a fully enclosed state. It can automatically stop and alarm when a fault occurs, which can avoid casualties and equipment losses. At the same time, the processing efficiency is very high.
High control accuracy and fast cutting speed. The central operation of the fully automatic circular saw machine is completed automatically. Employees can use it after a short training and it is controlled by PLC (no CNC program or other special expertise is required).
The high-precision cutting capability is impressive and is especially suitable for processing short pipes with a diameter of less than 102mm, ensuring processing accuracy.
It is very efficient in raw material processing. You only need to bundle the raw materials and transport them to the material rack. The circular saw will automatically complete all production processes, greatly saving manpower and time.
The circular saw machine is computer-controlled, so even without professional CNC programs, it can be easily used. It does not require too much professional knowledge and is easy to use by all types of operators.
The circular saw machine adopts an upper sawing method, which not only improves the cutting efficiency, but also significantly reduces the time required for cutting, further improving the overall work efficiency.
