What is Shear?
The word shear is the name given to a hand tool, quite similar to a scissor, but it differs due to its size and the force it can exert to cut different resistant materials. There are manual and mechanical shears.
The shears can cut different materials such as thin metal and wood sheets, as well as textiles, plastic, paper and cardboard. Now, in case the metal or wooden sheet is thick, a mechanical shear can be used, that is, it works with a motor.
The mechanical or industrial shear is characterized by making a straight cut, either in the metal or wood sheet, because it uses two blades that slide from one to the other from top to bottom and in the opposite direction.
The pushing force of the shear blades allows the sheet metal to be crushed and cut without leaving any chip residue.
There are different shears used in the metalworking industry, including: the guillotine, the lever, roller and circular.
Types of shear
There are different types of shears depending on the material to be cut and if it is intended, by use, to be a simple or industrial tool.
Metal shear: it is intended to make cuts in thin aluminum or metal sheets. These shears can make straight and curved cuts.
Clipper: This type of shear is used to make zigzag cuts on textile garments.
Pruner: This type of shear is used in the gardening trade and for cutting shrubs and trees.
Industrial shear: This shear works with an electric motor that allows you to put more pressure on the metal sheet. The industrial shear performs vertical cuts in different materials.
