A sheet metal guillotine shear consists of a shear table, upper and lower blades, a gauging device and a work-holding device.

The workpiece rests on the shear table whilst it is being cut. The work-holding device locks the sheet metal into place to ensure it doesn’t move or buckle under the stress caused by the cutting process.
Whether a manual, pneumatic or hydraulic guillotine shearing machine is being used, the sheet metal lies between an upper and a lower blade. The upper blade is gradually lowered, and the metal in between is ‘sliced’ with a high degree of precision. It is the gauging device that ensures the cut is made in exactly the right place.
In the past, the cutting process was powered by foot or by hand. However, a CNC-controlled guillotine shear for metal can remove the element of human error from the production process. Modern hydraulic guillotine shears ensure consistency and accuracy, as well as a fast and efficient manufacturing process.
