The difference between guillotine shears and swing shears

2025-07-29

The main differences between guillotine shears and swing shears lie in their movement, structural design, precision control, and applicable scenarios.

Core Working Mechanism Differences

Movement Trajectory
Guillotine shears: Employ vertical linear motion; the blade holder moves up and down along the guide rail via hydraulic drive, maintaining rigid contact during shearing.
Swing shears: The blade holder swings in an arc around a fixed axis; the shearing trajectory is limited by the mechanical structure.
Power Transmission
Guillotine shears use an all-steel welded body and a three-point roller guide rail system; hydraulic pre-tightening design eliminates guide rail clearance.
Swing shears rely on the lever principle to transmit power; the fulcrum has less force but there is a deviation in the movement trajectory.
Functional Performance Comparison

Shearing Accuracy
Guillotine shears control linear error within 0.1mm, especially suitable for narrow material processing.
Swing shears have a 0.3-0.5mm bevel error, and the sheet metal is prone to bow-shaped distortion.
Adjustment Capability
Guillotine shears support electric adjustment of blade clearance (0.01mm level) and shearing angle (0.5°-3.5°), adapting to different plate thicknesses.
Swing shears can only manually adjust the blade clearance, and the shearing angle is fixed.
Blade Life
Guillotine shears are equipped with four-edged blades and can be flipped for use, extending the life by 4 times.
Swing shears use double-edged blades, and need to be replaced entirely after wear.
Application Scenario Selection

Material Adaptability
Guillotine shears can shear high-strength alloy plates with a thickness of 8-40mm, with a maximum processing length of 10 meters.
Swing shears are recommended for processing ordinary carbon steel plates below 6mm.
Industry Preference
Guillotine shears are widely used in heavy industries such as automobile manufacturing and shipbuilding.
Swing shears are more suitable for lightweight sheet metal processing in industries such as home appliances and decoration
