Squaring Shear

Squaring shear is a large stationary machine that is used to cut down sheet metals. The machine requires the user to step on an pedal which then performers a vertical cut. Squaring shear cannot perform detailed cuts and is used mostly to reduce the overall length of sheet metal to a workable size. 

When comparing to torch cutting, It provides[1]:

• Cleaner cut
• Straighter edges
• Minimal to no kerf (the width of material removed during cutting)

However, squaring shear have the following disadvantages[1]:

• Cannot operate one materials with extreme high hardness such as tungsten
• Not ideal for low-volume applications
• Having risk of causing deformity

When operating, squaring shear generally have a guide which ensures the user can make straight and clean cuts. Therefore, very simple marking would provide great accuracy. It is important to determine the maximum thickness the squaring shear could handle (machine and material dependent) before proceeding to operation as exceeding the limit could cause damage both to the machine and the material[2].
