One of the major parts of fabrication is cutting the sheet metal or other material you are working with. Shear machines are pieces of equipment used to reduce material to a workable size, either for later stamping operations or directly on a press brake for forming. There are different types of shears that perform the same task in different ways. Although they have a variety of ways to power the shears; electric, pneumatic, manual, hydraulic, pneumatic, or mechanical, mechanical shears are considered "old" technology. The truth, however, is that mechanical shears are still made and used today, and those who know prefer mechanical operation to other options.

Mechanical shear machines are often the first step in metal fabrication. Cutting sheet metal or sheet metal is very similar to using scissors to cut paper or cardboard. The lower the rake angle, the better the quality of the cut part, but low rake angles require more pressure/tonnage to get through. The blades also need to come together with a minimum distance or offset (called blade gap). It depends on the thickness and type of metal being sheared. The smaller the gap, the better the quality of the cut edge and the more pressure/tonnage the shear will need to cut through the material.

Because cutting or shearing metal requires a lot of power and strength. The blades must be very sharp and the equipment must be durable. The shearing process also creates shocks in the machine, so a machine with excellent vibration absorption is required, which is where the robust design and high weight of mechanical shears come into play.

Mechanical shears have many advantages and use. They are a popular and essential piece of equipment in any manufacturing shop.

Shears make clean, straight cuts in flat material. This is a straighter edge. Due to the rigidity inherent in the design, the blades can be spaced closer together, providing the sharpest cut possible without burrs or rounded edges.

It allows your manufacturing or production facility to make products as precise as possible due to the mechanical shearing process. The machine's mechanical drive repeatedly performs the powerful process without bending, delivering sheared parts without bending or twisting.

Perhaps the greatest advantage of mechanical shearing is that it produces almost no waste. In what you call a "green" process, little hydraulics are needed, so electricity consumption is low, and the hydraulic fluid generates no heat. Unlike other cutting methods, shearing leaves no messy chips, chips, or other debris, and there is virtually no loss of material.

Since the machine can cut relatively small lengths of material at a time, your project can be precisely sized on a mechanical shear.

Another great advantage of using mechanical shears is that they are safer than other types of shears. Unlike torch cutting or other methods, the operator is kept away from the machine, minimizing the risk of burns or other injuries. Additionally, with proper protection, the operator is well protected from pinching and shearing blades. With regular maintenance and compliance with all safety regulations, the job can be done with little risk.
