Mechanical Shearing Machines

1 : a machine with blades or rotary disks for cutting sheets, plates, or bars (as of metal) 2 : a machine for shearing cloth usually consisting of a roller with cutters operating against a ledger blade. 3 : a machine for shearing sheep.Shearing, also known as die cutting, is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations.Shearing is a metal fabrication process that's used to trim and remove unwanted material from sheet metal. It involves the use of a machine or tool, such as a bench shear, to slice through sheet metal with extreme precision.Shearing machines are multipurpose devices used in the cutting of alloys and other sheet metal. Some shearing machines use a scissor-like, angular shear action to cut metal into sheets or strips. Other, larger machines use a straight shear action with the blade fixed at an angle as opposed to the angular movement.Shearing is the process of cutting sheet metal to size out of a larger roll or flat stock. As the material moves through the shear machine, cutting blades come together in order to fracture the material into separate, smaller pieces. This process creates quality clean cuts that can be repeated quickly.1a : to cut off the hair from. b : to cut or clip (hair, wool, etc.) from someone or something also : to cut something from shear a lawn. c chiefly Scotland : to reap with a sickle.
