Applications

Where It Works

Fabricators processing large super-format sheets up to 2000 x 4000 mm without a second setup
High-mix shops punching, nibbling, forming, marking, and tapping from one tool library
Operations adding thread cutting, stud welding, or an integrated fiber laser as needs grow

Features

The MultiPunch 4020 works super-format sheets up to 2000 x 4000 mm on a solid welded O-frame, with 28 tons of punching force and repositioning that extends length to 9999 mm.
A 12-station auto tool changer swaps tools in 1 to 5 seconds and the Rotation Index turns any tool a full 360 degrees, so up to 96 Trumpf tools cover high-mix work without stopping.
The universal head forms sheet from above and below with an active die, and an optional fiber laser up to 4 kW combines punching and cutting on one machine.
