Quick answer – three options, one clear choice:
Manual shear – Cut thin, soft metal (≤2mm) , very low budget, very low volume, or off-grid / portable use. No power required, but slow and labor‑intensive.
Swing beam shear – Cut thin to medium sheet (≤10mm) , limited budget & floor space, typical workshop use. Hydraulic power, good speed, lower cost than guillotine.
Guillotine shear – Cut plate over 10mm, stainless steel, or need high precision and heavy‑duty continuous operation. Highest cost, best accuracy, longest life.
Quick Overview: A swing beam shear features pendulum arc blade movement, compact structure and lower cost, optimized for sheet metal under 10mm. A guillotine shear adopts vertical straight blade movement, offering high cutting precision and rigid frame performance, designed for plate over 10mm and precision fabrication. Small & medium workshops pick swing beam shears; heavy-duty factories and precision metal shops choose guillotine shears.
Comparison Item | Swing Beam Shear | Guillotine Shear |
|---|---|---|
Blade Running Mode | Arc pendulum swing | Vertical linear up-down movement |
Structural Feature | Simple compact design, small floor space | Heavy welded frame, high integral rigidity |
Cutting Accuracy | Qualified for regular thin sheet cutting | High precision, minimal plate distortion |
Applicable Plate Thickness | Thin & medium plate (<10mm) | Medium & thick plate (max dozens of mm) |
Initial Purchase Cost | Economical, low budget | Higher investment cost |
Daily Maintenance | Easy operation, low maintenance cost | Slightly complex, ultra-long service lifespan |
Main Application | Small workshops, aluminum sheet, thin carbon steel batch cutting | Shipbuilding, steel structure, high-precision sheet metal fabrication |
Choose Swing Beam Shear: Tight budget, limited workshop space, mainly cut ≤6mm carbon steel / aluminum sheets
Choose Guillotine Shear: Process stainless steel, plate over 10mm, strict tolerance standard, long-term heavy-duty continuous work
Quick Overview: Reserve 20%-30% safety thickness margin when selecting shear machines. Example: For regular 6mm carbon steel cutting, choose 8mm or 10mm rated shear model. Stainless steel needs capacity downgrade; aluminum alloy allows upgraded cutting thickness.
Work Material | Capacity Conversion Factor | Practical Cutting Example |
|---|---|---|
Mild Carbon Steel | 1.0 (Standard benchmark) | 10mm rated machine = cut 10mm carbon steel |
Stainless Steel | 0.5 | 10mm rated machine = cut 5 mm stainless steel |
Aluminum Alloy | 1.2 ~ 1.5 | 10mm rated machine = cut 12~15mm aluminum sheet |
Count your maximum & daily regular plate thickness
Max thickness × 1.2 (fixed safety coefficient)
Select machine model with rated thickness ≥ calculated value
Important Note: For the same shear machine, wider cutting width reduces maximum allowable cutting thickness. A 3m-width shear cuts thinner plate than a 2m-width model.
Quick Overview: Confirm 7 core parameters before order: max cutting thickness, max cutting width, blade quality & gap adjustment, control system, motor power & factory power match, backgauge travel, adjustable shear angle. Unmatched parameters will cause machine failure or poor cutting effect.
Parameter | Function Explanation | Purchase Check Point |
|---|---|---|
Rated Cutting Thickness | Standard cutting thickness for mild carbon steel | Keep 20%-30% safety margin |
Max Cutting Width | One-pass full plate cutting length | Longer than your longest regular workpiece |
Cutting Blade | Material hardness, heat treatment, gap adjustability | Alloy steel blade + manual/automatic gap adjustment |
Control System | Manual / NC Digital Backgauge / CNC Full Automatic | Mass production: choose CNC intelligent system |
Motor & Power Supply | Motor power, industrial three-phase voltage | Fully match local factory power standard |
Backgauge Travel | Max moving distance of rear positioning stop | Meet fixed-size repeated cutting demand |
Adjustable Shear Angle | Upper blade tilt angle adjustment | Reduce sheet bending, edge burr effectively |
Machine Model | Carbon Steel Cutting Capacity | Cutting Width | Motor Power | Application Scenario |
|---|---|---|---|---|
4×2500 | 4mm | 2.5m | 5.5kW | Vent pipe, thin sheet ordinary fabrication |
6×3200 | 6mm | 3.2m | 7.5kW | General sheet metal workshop |
10×4000 | 10mm | 4m | 15kW | Medium-thick plate, steel structure parts |
16×6000 | 16mm | 6m | 30kW | Heavy industry, shipyard, large steel component |
Quick Overview: Shearing Machine Blades are core consumable parts. Focus on blade material, heat treatment, gap setting and service cycle. Standard gap: 5%-10% of sheet thickness; 10%-12% for stainless steel. Sharp blade + accurate gap improves cutting quality and prolong blade service life greatly.
