The Hydroil BM 20-350 at a glance
Since 1997, the BM 20-350 has been built as a horizontal press for many forming jobs on one machine. A 350-mm-stroke slide pushes and pulls with 20-ton force, and two rotary tables add a turning movement. With four workstations and two control stations, the BM 20-350 bends, shears, punches, notches, flares, reduces, rolls, and twists sections of bar, tube, and wire. It also forms brackets, clamps, and tube ends.
The press stroke and rotary tables complement each other. The press can bend a 70 x 10 mm flat bar on edge or flat to radii starting at 400 mm in sectors against a hydraulic end stop. Meanwhile, the rotary tables can create short radii and closed angles. The table and slide are part of the tooling, so users can often make forming tools from flame-cut plate themselves, which is economical even for single parts and prototypes. Quick-release hydraulic couplings drive additional movements, such as clamping or a second operation.
The Model 2003 has the same performance data as the previous model and adds a choice of two speeds for the slide and rotary tables, as well as three control modes: sensitive lever, three-hand control, and foot pedal.
