Manual shearing machine: used for cutting off sheet, pipe, profile and wire. Domestic number: Q02-X, X is shear thickness < BR /> Pedal cutting trigger: used for cutting thin plate and narrow plate; Pneumatic shearing machine: mostly used for shearing line, fast speed, high shear times. Mechanical shears: used for straight line shears of sheet metal. Shear thickness is generally 1-25mm, Domestic serial number is Q11-X-Y, X is shear thickness, Y is shear width. Hydraulic shears: used for straight line shears of sheet metal. Shear thickness is generally 6-32mm, Domestic serial number is Q11 (12) Y-X-Z, X is shear thickness, Z is shear width < BR /> Combined punching and shearing machine: is a very widely used metal laser cutting machine shear separation equipment, it can not only on the metal plate, profile cutting processing, but also in the plate and profile of the plane part of punching and die shear. It is because of its cutting process more forms, so it is called combined punching shear machine.
