CNC Horizontal Bending Presses

Horizontal bending press: when you need it instead of a press brake

A horizontal bending press bends rolled stock rather than sheet: round and square bar, flat bar, angle, small sections. The ram travels along the table, the part lies on it at working height, and the shape of the bend is set by interchangeable tooling — a punch and die for the specific operation. The same press is used to straighten parts. Such machines work in steel fabrication, forging and fitting shops, and in the production of fences, gates and brackets.

The catalog carries the NARGESA PP200CNC: 20 t force, 250 mm ram stroke, 9.8 mm/s working and 35 mm/s return speed, 950 mm working height, 665 kg. The ESA S625 CNC brings the ram to the set position with 0.05 mm repeatability: across a batch of identical parts the angle does not drift, and the program is stored for repeat orders.

What to check before ordering

• Section and material. The force a bend needs depends on the section, the steel grade and the die width. 20 t is for rolled stock and small parts, not full-width sheet: send a drawing and we will check it against the press.
• Tooling. What the press bends or straightens is defined by the set of punches and dies. It is chosen for your parts and agreed in the quotation together with the press.
• Stroke and part size. The 250 mm stroke limits how deep the ram goes into the tooling and what part fits between punch and die — check it against the drawing.
• Pace. Working stroke 9.8 mm/s, return 35 mm/s: the ram is slow, but force and position are under control along the whole stroke. Time per part depends on the bend depth and how many times the part is repositioned.

For bending sheet — a box, a cover, a flange along the full length — you need a vertical CNC press brake. Arcs and rings from profile or tube are bent on a profile bending machine, while large sections and shafts are straightened on higher-force hydraulic presses. All bending machines are in the press brakes.
