How Fast Is The Metal Guillotine Process?

Table of Contents

    Several variables, such as the guillotine type, the metal thickness, and the required cut quality, determine the rate of metal guillotining. In terms of speed, guillotines come in a range of sizes and configurations, with the fastest ones capable of slicing through metal sheets at several metres per minute.

    The guillotine’s cutting force is one of the vital variables that might influence the guillotining process’s pace. Cutting guillotines with greater cutting forces may swiftly sever thicker metal sheets compared to those with lesser forces. Aside from the effectiveness of the hydraulic or mechanical system that powers the guillotine, the sharpness of the blade and other factors can also affect the speed of the procedure.

    Metal guillotining, in comparison to other metal cutting technologies like plasma or laser cutting, is often a quite quick operation. Nevertheless, the necessity for accuracy and quality must constantly be balanced with the process’s pace. While it’s tempting to speed up the guillotine to get more done in less time, doing so increases the risk of problems like uneven cutting or sharp edges.

    Why Is It Important To Choose The Right Metal Guillotine?

    important to choose the right metal guillotine

    Is It Hydraulic Or Mechanical?

    Consider the capacity you will require first. Guillotine widths range from 1 metre to 5 metres, and thicknesses from 0.1 mm to 25 mm. The ideal machine for the job will depend on the material you intend to cut.

    The type of machine you require-mechanical or hydraulic-should be your next thought. Bruce lays out the benefits of each in the video. To begin, hydraulic machines can cut material with a thickness of up to 25 mm, whereas mechanical guillotines can only handle thicknesses of up to 4 to 5 mm.

    Execution Using Mechanical Means

    The mechanical option is superior in terms of ease of use. Because it doesn’t require hydraulic fluid, the mechanical machine is not only smaller and less complicated than its hydraulic equivalent, but it is also quieter and more environmentally friendly. The mechanical machine’s high cut-per-minute pace makes it an excellent choice for light sheet metal materials up to 4mm in thickness.

    Hydraulic Guillotine With A Swing Beam

    You get a lot of bang for your buck with the hydraulic swing beam guillotine. Materials with a thickness of more than 1.5 mm and up to 20 mm are the best candidates for the swing beam option. These types are built to handle heavy materials with a set rake angle. According to our customers, this is the best option out there.

    Hydraulic Guillotine With Adjustable Rake

    A variable rake hydraulic guillotine is ideal if you have a wide variety of thicknesses to cut. When you’re cutting thin, tiny strips, the variable rake gives you more control over the cut. To lessen the possibility of the cut component twisting, the variable rake lets you adjust the rake on the top beam while it cuts, as the name implies. You could expect the most exact cut from this design, but it comes at the highest price tag.

    Additional 

    To make cutting even easier, there are a plethora of optional options to choose from. With a longer squaring arm or support arms, you can cut a narrower strip from a wider sheet, even when most of the material is at the machine’s front. With these add-ons, you won’t have to worry about the material bowing at the machine’s front.

    What about the number of pieces you’re cutting? If so, you might want to consider a stacker and a conveyor. Unfortunately, these solutions can slow down the cut-per-minute rate and aren’t cheap.

    Types Of Shears Used In Sheet Metal Manufacturing

    In the realm of sheet metal fabrication, a variety of shearing instruments are indispensable for achieving precision and efficiency. This article delves into the metal guillotine among six other widely utilized shearing tools in the industry.

    Crocodile Shear

    Employed for slicing through extended pieces of metal like I-beams, angle bars, pipes, or reinforcing bars, or for preparing scrap metal by removing unsuitable parts for shredding, crocodile shears are named for their pivot-mounted jaw, operated by a hydraulic mechanism. The process begins as a piston moves, gradually bringing the upper “jaw” down to the base to initiate the cut. Crocodile shears are valued for their robustness, durability, and cost-effectiveness, despite producing somewhat uneven surfaces.

    Sheet Metal Guillotine

    Featuring both upper and lower shears, a material clamping unit, a measuring tool, and a shearing table, the guillotine operates through manual, hydraulic, or mechanical power. It secures the metal in place and slices through it with a blade moving across a stationary counterpart. The ability to angle the moving blade helps minimize effort for larger cuts. Its efficiency and affordability make it ideal for bulk production, although it may leave rough edges, which is less of a concern if further welding or processing is planned. Safety measures are crucial when operating a guillotine.

    Tabletop Shear

    Tabletop shears, mounted on benches for added leverage through a compound mechanism, are excellent for shaping medium-sized sheet metal. This versatile tool can handle various materials, including round and square bars, and those with specific profiles like 90-degree angles and T-sections. Especially effective on larger models, tabletop shears offer quick, clean cuts without burrs.

    Electric Shears

    Operated by hand, electric shears can be powered by electricity or air pressure, making them suitable for trimming large metal sheets. They achieve cuts by exerting force between a moving blade and a stationary one, ideal for straight cuts or curves with significant radii. Electric shears are noted for their versatility in cutting paths, efficiency, accuracy, longevity, and quality of finish.

    Throatless Shears

    Distinct in design, throatless shears allow for unrestricted movement of the material, enabling straight, smooth, or complex shapes to be cut with ease.

    Hand Shears

    Hand shears, or snips, are manual tools for cutting sheet metal. They come in two primary forms: tinner snips for cutting through mild steel and low-carbon materials, featuring long handles and short blades for ease of use. Straight-pattern tinner snips are optimal for straight lines or gentle curves, whereas duckbill-pattern snips excel in tighter curves. Varieties include circle patterns for circular cuts, hawksbill for internal and external radii, and other specialised forms for intricate tasks.

    Nibbler Tools

    Though some nibblers share similarities with hand shears, most operate through a punch-and-die mechanism, with the blade moving linearly around a fixed die to create cuts with minimal distortion. Nibblers are appreciated for their durability, quick and precise cutting capabilities, and low force requirement for material feeding.

    Uses For A Metal Guillotine

    The accuracy and efficiency with which guillotines cut straight-line metal sheets make them indispensable in many different industries. When it comes to the fabrication and manufacturing processes, they play a crucial role in making parts for cars, appliances, and machines. Guillotines are vital in the aerospace industry for making precision panelling and chassis components, and in the automotive industry for shaping body panels and other chassis parts. Metal roofing sheets, girders, and beams are frequently cut to size using guillotines on construction sites.

    Similarly, they are employed in the shipbuilding process to form the enormous metal sheets used to construct the hulls of ships. The use of guillotines is essential in the electrical sector for the creation of panels and enclosures and in the HVAC business for the creation of ducting and vents. The guillotine’s precise cutting powers are also utilised by artists dabbling in metalwork, signs manufacturers, and even jewelry-makers. Finally, guillotines are used by the railway sector to create the essential components of trains and associated equipment. Because of its essential role in guaranteeing the practicality and beauty of a wide range of items and buildings, the guillotine is ubiquitous across these industries.
