Precision Cutting with Hydraulic Guillotine Shearing Machines
Hydraulic guillotine shearing machines achieve exceptional cutting precision through advanced design features and operational mechanisms.
CNC Backgauge System
Modern machines utilize computer-controlled backgauges with servo motors and digital readouts for positioning accuracy within ±0.1mm, ensuring consistency for repetitive cuts.
Blade Gap Adjustment
Precise gap settings between upper and lower blades are critical for clean cuts without deformation:
| Material Thickness | Recommended Gap |
|---|---|
| 0-3mm | 0.03-0.05mm |
| 3-6mm | 0.05-0.1mm |
| 6-10mm | 0.1-0.15mm |
Hydraulic System Advantages
- High-pressure cylinders provide smooth, consistent cutting force
- Rigid frame construction minimizes vibration
- Controlled blade movement ensures straight cuts
- Hydraulic clamping prevents material movement during shearing
Safety & Stability Features
Integrated sheet clamps and vibration-dampening designs maintain material position and cutting accuracy throughout the shearing process.
Maintenance Requirements
Regular blade sharpening and alignment checks are essential to maintain precision. Typical maintenance intervals:
- Blade inspection: Every 40 operating hours
- Hydraulic fluid check: Weekly
- Full alignment calibration: Every 6 months
Precision Cutting Capabilities
- Straightness tolerance: ≤0.1mm/m
- Angular tolerance: ≤0.5°
- Repeatability: ±0.05mm
- Minimum burr height: ≤0.02mm (with proper setup)
With proper setup, calibration, and maintenance, hydraulic guillotine shearing machines can reliably produce precise cuts for various metalworking applications, from thin sheet metal to heavy plates up to 25mm thick.
