Guillotine shears are a type of cutting tool used primarily for shearing metal sheets and other materials. They operate using a straight blade that moves down in a vertical motion, similar to a guillotine, to make precise cuts. This design allows for clean and accurate cuts, making them popular in metalworking and fabrication industries. These shears can handle various thicknesses of material, depending on their size and power. They are often powered by hydraulic or mechanical systems, providing the necessary force to cut through tough materials. Safety features are typically included to protect users during operation.
