The Stierli-Bieger 820 CNC is a very efficient, versatile bending and straightening machine that is equipped with a modern touchscreen colour display and 2-axis control. The operator can program the system very easily. The bending angles required can be programmed and adjusted after the first angle. 200 programs can be saved. Other programs can be swapped in via an interface. The stroke setting can be adjusted in the program at any time in +/- 0.1° steps (or with +/- 0.1 mm stroke adjustment) to offset material-related tolerances. It is operated with the foot switch or the special manual control cable, with which jogging mode, automatic mode and the straightening function can be confirmed.
Its solid steel construction provides a very rigid machine stand. The working plate ensures effective positioning of very large bent parts. The 300 m tool holder enables straightening with high tools. 300 mm high tools or the support quick-change holder with standard tools of 300 mm height are used for bending. The special oil-lubricated guided cylinder requires no maintenance! The working pressure and speed can be controlled continuously and easily. With the working stroke of 350 mm, stamping and form bending work can be carried out easily. Gas pipes up to 3” can also be bent easily. The machine can be transported easily inside the factory with a crane or fork-lift truck. Various tool trays provide organised storage of the tools so that they are always readily to hand.
