Hydraulic Tilting-Type Guillotine Shear
The Liva hydraulic tilting-type guillotine shear cuts sheet from 4 to 25 mm with its tilting-type structure. A robust body, 4-edge blades, a ball material support table and an NC-controlled back gauge give a precise, reliable solution for general shearing.
Key Features
- Robust body structure: a powerful design for perfect cutting
- Hardened and ground blades; 4 cutting edges on both top and bottom blade
- Blade gap is adjusted manually, steplessly and easily
- Tilting-type structure: a proven, rigid design
- Spring-loaded down-holder cylinder: leaves no mark on aluminum or other sensitive material
- Ball material support table reduces friction and scratching of the sheet during feeding
- Collapsible front finger protection (to CE norms)
