A bending machine is a commonly used mechanical device in metalworking, primarily designed to apply a certain amount of pressure to bend metal sheets. It is widely used in industries such as manufacturing, construction, automotive, and home appliances. With continuous technological advancements, the types of bending machines have expanded, among which CNC bending machines (Computer Numerical Control bending machines), known for their high precision and efficiency, have gradually replaced traditional mechanical bending machines.
Basic Functions and Applications of Bending Machines
The basic function of a bending machine is to bend metal sheets (such as stainless steel, aluminum alloys, iron plates, etc.) into the desired angles and shapes through external force. Bending machines can be classified into manual bending machines, hydraulic bending machines, mechanical bending machines, and CNC bending machines based on their control methods, working principles, and functions. Among them, CNC bending machines are high-precision devices controlled by computer numerical control systems, capable of automated operations and precise bending control.
CNC bending machines can automatically execute complex bending actions by inputting programs, reducing human errors, improving production efficiency, and ensuring high bending accuracy. In contrast, traditional bending machines usually rely on manual operations, which, while simple in structure, have relatively lower precision and efficiency.
