Aluminum sheet workpieces are prone to warping during the drilling process, due to the high expansion coefficient of aluminum sheet material, and the internal stress generated during the processing cannot be effectively controlled. Therefore, before drilling and processing, precision leveling treatment must be carried out to remove internal stress and ensure the flatness of the aluminum plate workpiece.

A section straightening machine is a specialized piece of equipment designed to straighten various types of metal sections, such as beams, channels, angles, and other structural shapes. These machines are crucial in industries where precision and structural integrity are paramount, such as construction, manufacturing, and metal fabrication.
