When you apply a high-pressure tool through a metal plate and remove part of the metal, the process is called shearing. Shearing is one of the oldest metalworking processes available and is usually the first process. The electric shearing machine is used when manufacturing fabricated parts. It is industrial equipment with rotary disks and blades used to cut hard iron sheets and metal bars. Hydraulic shearing machines are used to cut circular blanks and rings from metal and are operated by an electric motor. The best types of metal for shearing are bronze, aluminum, brass, and mild steel. Sheet metal shearing machine is cost-effective and easy and hence preferred in industries and even homes.
A shearing machine for sale is used for cutting sheet metal to size out of a larger flat stock or from roll stock. The metal to be cut is held in place with hold-downs. 90°cuts are positioned by a squaring arm with a scale on it or with a back gauge. Other angles are possible with an angle gauge. Large machines with shadow cut lines will have a light that shines over a wire which projects a thin shadow line exactly where the cut line is which is useful if you mark your metal with a tape measure. The shearing process can produce a shear edge burr, which can be minimized to less than 10% of the material thickness. This is a function of clearance between the blades, and the sharpness of the cutting blades.
A quality electric sheet metal shear can save many hours on further processes such as bending, welding, and assembly so it is important that you ensure you are capable of making quality, clean cuts that are square, accurate, and can be repeated quickly. When it comes to shearing metal, BLMA, China's top 10 shearing machine manufacturers, offers a selection of high quality, high production hydraulic sheet metal shearing machines for sale that are a cut above the competition.
