Hydraulic Guillotine Shear with Precision Backgauge System

The hydraulic guillotine shear with precision backgauge system is engineered for sheet metal fabrication environments that require exact repeatability, micron-level control, and efficient operation in batch processing. This advanced guillotine shear integrates a CNC-controlled backgauge mechanism, delivering unmatched positional accuracy and automation capabilities for consistent, high-quality cuts in steel, stainless steel, and aluminum.

High-Accuracy Backgauge System for Repetitive Cutting

One of the most critical performance factors in industrial shearing is the backgauge system. This model features:

Servo-driven programmable backgauge with an accuracy of ±0.05mm

Linear guide rail and ball screw motion for smooth, backlash-free operation

Front control interface allowing real-time adjustment of cut depth and positioning

Multiple memory slots for storing cutting programs and material presets

Operators can pre-program cut lengths and quantities, making the machine ideal for automated batch production and minimizing manual measurement errors.

Hydraulic System Stability and Cutting Power

The guillotine shear is powered by a closed-loop hydraulic system, which ensures:

Constant pressure delivery

Silent operation with low vibration levels

Precise blade movement along the vertical plane

Minimal thermal deviation during prolonged usage

The hydraulic cylinder force is evenly distributed across the blade length, preventing torsion and ensuring clean, burr-free cuts even on 12mm+ thick plates.

Material Compatibility and Application Scenarios

This hydraulic shear is optimized for:

Carbon steel: Up to 16mm

Stainless steel: Up to 10mm

Aluminum sheet: Up to 20mm

Coated or laminated metal: Without damaging surface treatments

Applications include:

Duct fabrication workshops

Structural steel production

Metal furniture and chassis fabrication

Shipbuilding and container manufacturing

Its programmable gap control ensures minimal blade clearance for soft and thin materials, reducing edge deformation.

Enhanced Safety and User Interface

Safety and ease of use are critical in industrial settings. This shear includes:

Light curtain or laser safety sensors for hand protection

Two-hand start operation to prevent accidental activation

Emergency stop at multiple access points

Touchscreen HMI for controlling shear angle, stroke length, and backgauge positioning

All operating parameters can be adjusted via a CNC panel, reducing setup time for different materials and job orders.

Blade Design and Maintenance

The guillotine shear blade is constructed from tool steel, offering:

High wear resistance

Long service life

Quick-change design with mechanical blade clamps

Four usable cutting edges

Scheduled lubrication alerts and diagnostic messages ensure minimal downtime and consistent cutting performance.

FAQs

What is a backgauge in a hydraulic guillotine shear?

A backgauge is a positioning system that moves behind the sheet to define the cut length, allowing precise and repeatable cuts in automated operations.

How does a programmable backgauge improve shearing efficiency?

By automatically adjusting cut positions and storing material presets, a programmable backgauge reduces manual errors and increases cutting speed in batch production.

Can a hydraulic guillotine shear handle variable sheet thicknesses?

Yes, most high-end models feature automatic blade gap and rake angle adjustment systems, allowing them to adapt to different material types and thicknesses.

What is the difference between CNC and manual backgauge systems?

CNC backgauges allow stored programs and automatic movement, while manual systems require operator input for each adjustment, leading to slower setup and higher error rates.

Why choose a guillotine shear over a swing beam shear for thick plates?

Guillotine shears maintain a straight vertical blade motion, making them better for thick or high-strength plates, delivering a cleaner cut with less distortion.
