Hydraulic shear KHT V 4020 CNC

sheet metalguillotineCNC

Description
The KHT V 4020 CNC hydraulic guillotine shears are heavy‑duty, CNC‑controlled plate shears engineered for high‑precision metal cutting in industrial production. A guided cutter bar with adjustable cutting angle minimises workpiece twist and reduces rework. The intuitive Cybelec touchscreen control automatically positions cutting gap, angle and length based on material parameters. Standard knives are rated for stainless steel and a robust, motorised back gauge ensures repeatable results. A wide range of standard and optional equipment adapts the machine to diverse production needs.
