The Difference Between Guillotine Shears and Swing Shears

●Working Principle Is Different

Working principle of guillotine shears:

The guillotine shearing machine adopts all-steel welding of frame structure; four-corner and eight-sided right-angle guide rail, high precision, good rigidity, and hydraulic pre-tensioning. The hydraulic system adopts two-way cartridge integrated valve; The entire system adopts; and can be equipped with stroke digital display, photoelectric protection device, and mobile workbench. The guillotine shear has the double-action function of the upper slide and the lower hydraulic cushion. The working pressure stroke can be adjusted within the specified range according to the process requirements. Convenient operation, centralized control by buttons.

Working principle of pendulum shears:

The hydraulic pendulum shears are arc-moving, and the arc blade is quite difficult to make. Generally, the shim is used to fill the shim after the blade, so the gap obtained is not accurate, and the cut sheet is not ideal. Because of the arc movement, the blade cannot be made into a rectangle but should be made into an acute angle, so the force of the blade is not ideal, and the blade damage is also severe.

●The CNC shears are divided into gate shears and swing shears from the working principle. In addition to the different working principles, the guillotine shears and the swing shears have the following differences from the actual processing and use links:

⒈The precision of the guillotine shears can be higher, reaching twice that of the pendulum shears;

⒉The shear angle of the guillotine shears can be adjusted according to different plates, while the shear angle of the pendulum shears is fixed;

⒊The gate-type shearing machine has 4 blade-edge surfaces, while the gate-type machine has only 2 blade-edge surfaces. In the process of use, the knife-edge surface can be replaced, and the guillotine machine has more knife-edge surfaces and longer service life;

⒋The guillotine shearing machine has a wider range of use and is suitable for most metal sheet shearing processing. Stainless steel, aluminum alloy, and other metal sheets can be processed;

⒌The guillotine shearing machine is more expensive to produce, and the price of the Shenpu shearing machine is more expensive. From the perspective of cost-saving, if the precision of the shearing plate is very low and the thickness of the shearing plate is relatively thin, you can choose to buy a pendulum shearing machine.

⒍For sheet metal processing over 8mm, guillotine shears must be selected, because the principle of pendulum shears restricts it from cutting thick plates.
