Service overview
It is the most common metal cutting process. In this process, a piece of sheet metal separates by applying a high shearing force. The method uses shearing force to cut sheet metal in straight lines.
The most common process to cut the sheet is a shearing process. Shearing machines operate either manually or with the help of hydraulic, pneumatic, or electric power.
Components of shear machine
A shear machine comprises a table with support arms to hold the sheet, stops or guides to secure the sheet, upper and lower straight-edge blades, and a gauging device for precise positioning of the sheet.
Types of sheet metal shears
There are two different types of shears as follows
In this, the cutting process takes place by guiding the upper cutter straight through the material. The upper cutter does not cut through the metal sheet panel vertically. The line of action of the shear force is not at right angles, and it deviates by two degrees.
In this, the upper cutter is not guided by a link straight through the material, from the top down. It is a circular movement in which the cutter touches the material at right-angles with a minimal cutting clearance. The method is suitable for thick metal plates.
