Shear machines, commonly referred to simply as shears, are used for cutting metal sheets into desired sizes and shapes. They operate using a process called shear cutting, where two blades slide past each other to create a clean cut. The upper blade is typically fixed at a certain angle, while the lower blade is adjusted according to the material thickness and type. This adjustment enables operators to cut through various materials, including steel, aluminum, and composite metals.
