Understanding How the Shearing Process is Performed

June 24, 2021

Metal fabrication generally is a series of processes that can generate different machines, structures, products, and others from raw metal materials. Some of the processes being done with metal fabrication include burning, cutting, forming, machining, and welding.

A lot of industries maximise metal fabrication. It can effectively produce high-quality products from raw metal materials instead of assembling ready-made components that typically have some drawbacks. Metal fabrication is likewise utilised by industries due to its capability to produce products with a wide array of shapes and other properties. It is also cost-effective as different metal fabrication processes can be conducted to produce tons of products in just one go for long-term operations.

The Working Principles of Shearing

One of the processes that are included in metal fabrication is shearing. Shearing is a metal fabrication process that utilises blade-affixed machines or tools to trim and remove materials from sheet metals. With the said machines and tools, specific parts of workpieces are precisely cut and sliced without utilising heat. Shearing likewise do not generate waste, minimising material loss.

Before shearing is conducted, the workpiece or the sheet metal must be placed first between the blades of the tool or machine. The squaring arm, at this point, will ensure that the workpiece will be in the correct position. Once the workpiece is in position, the top blade will drop to cut through it while the lower blade will press through the bottom of the workpiece.

There are tons of shearing tools and machines that can be utilised for the shearing process. Some of these tools and machines include bench shears and guillotine machines.

Shearing Benefits and Drawbacks

The shearing process has been preferred by many industries due to its accompanying benefits. For one, the tools and machines used for shearing can carry out the process without experiencing any delays and generating wastes. And even with fast and clean operations, the shearing process can still generate cuts that are neat and smooth. Shearing can even sustain high-quality production despite manufacturing tons of metal products at room temperature.

Shearing can also be done with different types of metals. Aluminium, bronze, copper, iron, stainless steel, and others can all be processed by shearing.

But despite its benefits, the shearing process can still manifest some drawbacks. One of the drawbacks of shearing is that it can sometimes cause defect and deformity in workpieces. It cannot also process workpieces that are made from hard metal. Low-volume manufacturing applications, ultimately, cannot be truly effective with the shearing process.

Quality Shear Blades are Important

For the shearing process to be effective, the blades used for the tools and machines must be durable, long-lasting, and sharp.
