What is Metal Shearing?

Metal Fabrication | November 28, 2023

If you have ever wondered about the processes that transform sheets of metal into precision parts or products, you might have come across the term “metal shearing”. At LWS Manufacturing & Welding, we want to help you fully understand what metal shearing is and how to do it correctly. That is why we have put together some information, shedding light on metal shearing and how it is supposed to be done, breaking it down into easy-to-understand terms.

The Metal Shearing Process

Metal shearing is a process used to cut straight lines on flat metal stock. In essence, the process involves placing a large piece of metal under a blade and pressing the blade down, “shearing” the metal into desired sizes and shapes. This is an efficient way to reduce large metal sheets into smaller, more manageable pieces for further processing.

When is Metal Shearing Needed?

One of the most common reasons for metal shearing is to break down large sheets into more workable sizes for various projects, including custom metal fabrication projects. Instead of working with an unwieldy sheet, manufacturers can shear them down to the exact dimensions they need. If the edges of a metal sheet are jagged or irregular, shearing can be used to clean and straighten them, ensuring safer handling and a more professional finish.

Before metals undergo further fabrication processes like bending, forming, or welding, they often need to be sheared to the right size. This ensures that there is no wastage of material and that each piece fits perfectly into the final product.

How Metal Shearing is Done

1. Selection of the Right Equipment

The choice of shearing machine will depend on the type and thickness of the metal, as well as the desired end result. Common types include bench shears for smaller jobs and power shears for industrial applications.

2. Setting the Measurements

Before the shearing begins, it is crucial to measure and mark the metal sheet. Precision is key here, as any errors can result in wasted materials or a need for rework.

3. Securing the Metal

The metal sheet is then secured in place using clamps. This ensures that the sheet does not move during the shearing process, leading to an accurate and clean cut.

4. Operating the Shear

Once everything is set, the operator activates the shear. The blade comes down onto the metal sheet, applying pressure until it slices through.
