Swing Beam Shearing Machine VS Guillotine Shearing Machine
Posted by gldma on September 7th, 2017
Hydraulic Shearing machine, in simple words, is a device that separate metal sheets into parts. sheet metal cutting machine manufacturers are continuously improving the design and performance of their products to meet customer requirements. In accordance with shear design, it can be subdivided into guillotine and swing beam. Although they are extensively used in various industries, they still have something different as follows:
Swing beam shearing machine
The cutting angle of the swing beam shearing machine is fixed, so it cannot be adjusted. It also uses a semi-cylinder which contains no lubrication, making it more susceptible to wear and the need for replacement. The benefits of this type of shear, however, are that they work well for non-metallic materials because of their superior ability in the fast production of pressure formed and sheared products. Less shear angle creates a faster production ratio. They also work well with sheet metal, aluminum, and steel. Adjustments for this hydraulic shearing machine can be made in the stroke and pressure which aids in more precision of formation with less distortion of the final product. This design is most commonly used by Asian and less expensive European manufacturers. A swing beam causes the relationship of the top blade to the work piece to change throughout the cut. One advantage to a swing beam shear is they are typically less than a guillotine shear. The other advantage to a swing beam design is speed in the form of faster strokes per minute. Swing beam shearing machine performs well in thinner material 1/4” and under.
Guillotine shearing machine
This type of shearing machine is typically more expensive, accurate and stronger overall (heavier in weight of machine). A guillotine shear by design has a drive system that ensures the upper blade comes straight down through the material from start to finish. The blade does not change position in relation to the material through the cut. Guillotine shears perform well especially for larger capacity machines 1/4” and up. One main feature is a guillotine shears ability to adjust the rake angle (cutting angle of top blade) this is beneficial for variations in material thickness. The thicker the material, the larger the angle should be. The hydraulic system is programmable to meet the requirements of the project, e.g. stroke pressure, and through the four angle and eight surface right guides. They are precision designed for high accuracy with the capacity for the dual action of an upper stroke and the hydraulic pressure pad on the bottom. The accuracy of the guillotine shearing machine is higher than that of the swing beam shear and tends to be smoother with less distortion.
