Digima die for the AMADA 800x150x26 4s L 3200mm 160T press brake
Digima die for an AMADA press brake, TYPE 800x150x26, 4 segments, L=3200mm, pressure: 160T
We are pleased to present a high-quality Digima upper die, designed for the precise bending of sheet metal on press brakes using the Amada clamping system. This tool is exceptionally versatile and is fully compatible with machines with a working pressure of 160 tonnes. It is manufactured from high-grade T8A tool steel, ensuring excellent structural stability and resistance to fracture under high loads.
The set, with a total length of 3,200 millimetres, consists of 4 precision-machined segments, each 800 millimetres long. A key factor in enhancing the punch’s durability is the high-frequency induction hardening process applied to the working edge, which has achieved a hardness of HRC 45 ± 2 degrees. As a result, the punch tip retains its original geometry throughout thousands of bending cycles, ensuring perfect angle repeatability. The precision-ground tip, with an angle of 85 degrees and a radius of R 0.5 millimetres, enables bends of the highest aesthetic quality.
Suitable for the PBH-160x3200 press and others of similar dimensions
