Types of Guillotine Shears
Guillotine shears are categorized primarily by their blade configuration and control systems. The choice depends on the application’s precision and automation requirements. Anhui Yawei (www.ahycncs.net) offers both types of machines.
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Fixed Angle Shears | Blades are set at a fixed angle. Suitable for less demanding cutting applications. | Simple design, lower cost | Less precise cuts, may cause workpiece distortion, especially on thicker sheets |
| Variable Rake Angle | Blades’ cutting angle is adjustable. Optimized for precise cutting of various materials. | Higher precision, reduced workpiece distortion, better cutting performance for different thicknesses | More complex design, higher cost |
Choosing the Right Guillotine Shear
Selecting the appropriate guillotine shear involves careful consideration. Factors like material type, thickness, required cutting length, and budget all play a role. Consult with suppliers like Anhui Yawei (www.ahycncs.net) for expert guidance. Assess your specific needs to ensure the chosen machine meets your requirements. The level of automation required influences the choice between manual and CNC controlled models.
Conclusion

FAQs
1. What is the difference between a guillotine shear and a swing beam shear?
Guillotine shears use a fixed blade and a moving blade that descends vertically. Swing beam shears have a pivoting upper blade, making them suitable for thinner materials.
2. What safety precautions should be taken when operating a guillotine shear?
Always use appropriate personal protective equipment, ensure proper machine guarding is in place, and follow all manufacturer safety instructions. Never place your hands near the cutting area.
3. How often should guillotine shear blades be replaced?
Blade replacement frequency depends on usage and material type. Regular inspection for wear and tear is essential. Consult the manufacturer’s recommendations for optimal lifespan.
4. What are the common maintenance tasks for guillotine shears?
Regular lubrication, blade cleaning, hydraulic fluid checks, and overall machine inspection are crucial for maintaining performance and extending lifespan.
5. What factors determine the price of a guillotine shear?
Price is influenced by cutting capacity, control system (CNC or manual), automation features, brand reputation, and overall build quality. Larger and more automated machines generally command higher prices.
