Hydraulic Adjustable-Angle Guillotine Shear
The Liva hydraulic adjustable-angle guillotine shear cuts sheet from 6 to 40 mm. A small cutting angle reduces twist and deformation of the sheet; the ESTUN E21S NC control and precise back gauge give clean, efficient cutting in general shearing work.

Key Features
- Powerful body structure for stable, robust cutting
- Hardened and ground blades for long life and precise cutting
- Small cutting angle reduces twist and deformation and improves cut quality
- Blade clearance adjusts quickly and suits different sheet thicknesses
- Back gauge can be fine-adjusted; the stroke adjustment function improves processing efficiency
- Special support frame for easy use; the roller support plate does not scratch the sheet
- Safety to CE standards

Details
Siemens Main Motor
Extends machine life and keeps the machine running quietly.
Rexroth Valve
Hydraulic valve brand of the Bosch group.
High-precision Back Gauge
Fine ball screw and ground rod; swings up to cut workpieces beyond the back gauge range.
CNC Clearance Adjustment
System-controlled automatic positioning and rapid adjustment.
Optional Equipment Details
Angle Protractor
Mounted on the left of the front beam; makes angled cutting easier.
Lighting Alignment
Aligning by light helps bring a hand-marked sheet to the cutting line.
Front Feeding Device
Brush worktable with steel balls reduces scratches; pneumatic clamps parallel to the table make loading easier.
