Guillotine Shears

Guillotine shears are industrial cutting machines used to separate sheet metal along a straight line. Also known as squaring shears or power shears, these machines can be foot-operated, mechanically driven, or hydraulically powered. A guillotine shearing machine clamps the workpiece in place with a ram, then lowers a moving blade across a fixed blade to produce accurate, clean cuts. The blades are oriented in opposing directions to ensure a precise, straight shear line.

Key characteristics of guillotine shearing include a chip-free cutting method, clean separation along straight lines, and consistent results across a wide range of sheet metal thicknesses — making them an essential tool in sheet metal processing.

Larger guillotine sheet metal shears often feature a moving blade set at a slight angle, allowing the cut to progress gradually from one side of the workpiece to the other. This reduces the force required and minimises chips and surface inconsistencies in the finished piece.

A hydraulic guillotine shear is the preferred choice for high-volume manufacturing environments, as it reduces the need for manual adjustments during operation. The combination of precision blade design, a heavy-duty frame, and CNC control delivers consistent accuracy across large production runs. Because modern hydraulic machines are increasingly built with lightweight materials — which can introduce deflection during cutting — CNC programmes are used to automatically compensate by adjusting both the rake angle and blade gap in real time.

A sheet metal guillotine shear consists of a shear table, upper and lower blades, a gauging device, and a work-holding device – each playing a vital role in achieving precise, clean cuts.

The workpiece rests on the shear table during cutting. The work-holding device clamps the sheet metal firmly in position, preventing movement or buckling under the stress of the cutting process.

Whether using a manual, pneumatic, or hydraulic guillotine shearing machine, the sheet metal is positioned between an upper and a lower blade. The upper blade descends gradually, slicing through the material with a high degree of precision. The gauging device ensures every cut is made at exactly the right position.

Historically, the cutting process was powered by foot or by hand. Today, a CNC-controlled guillotine shear eliminates human error from the production process. Modern hydraulic guillotine shears deliver consistency, accuracy, and high throughput – making them an essential asset in efficient sheet metal fabrication.

Guillotine shears are manufactured across a wide range of sizes, making them one of the most versatile solutions for sheet metal cutting in modern fabrication. Whether deploying a pre-owned plate shear or a new hydraulic system, these machines deliver precise, repeatable cuts – making sheet metal plate production cost-effective for operations of all scales. The resulting plates are used in the construction of industrial machinery, structural components and replacement parts.

A plate shearing machine is well suited to cutting standard sheet metal as well as non-ferrous metals such as brass, bronze and aluminium. Cuts of up to 15 metres in length are achievable, covering a broad spectrum of manufacturing requirements. It is worth noting that stainless steel is generally not compatible with guillotine shearing, as its tendency to strain-harden makes clean cutting difficult.

A used guillotine shear offers an excellent way to equip your metalworking operation with precision cutting equipment while keeping capital expenditure to a minimum. Whether you need a conventional or CNC model, the secondhand market provides access to high-quality machines from leading manufacturers such as TRUMPF, FISCHER, ATLANTIC, IRLE and SAFAN – brands synonymous with accuracy and durability. Buying a used guillotine shear from a reputable manufacturer ensures you benefit from proven engineering and reliable performance at a fraction of the cost of new equipment.
