Stierli 420 CNC

Fast, Powerful and Precise Copper Bending

Description

The Stierli 420 CNC is an efficient horizontal bending machine for a variety of straightforward and repeatable applications where considerable power is demanded. With 420 kN (46 US tons) of working power, it can be programmed and operated with an easy-to-use modern touchscreen color display with 2-axis control. Bending angles and segments can be programmed and adjusted after the bending operation. Stroke setting can be adjusted in the program at any time in +/- 0.1° increments to offset material-related variances. Up to 200 programs can be saved and other programs can be swapped in via an interface.

The Stierli 420 CNC’s jogging, automatic and straightening modes are operated with a foot switch or manual control cable. A 130 mm tool holder and 80 mm diameter pin provide a versatile and convenient tool mounting system. The machine table has three additional tool holes for pipe bending or straightening.

Stierli 420 CNC bending machines come standard with a large working plate, ensuring effective positioning of very large bent parts. The machine features a special oil-lubricated guided cylinder which requires little maintenance and no open guide. It can be transported easily inside a factory with a crane or pallet truck.

Two tool trays provide organized storage of the tools so that they are always available.
