The CORMAK RBM40HV is an electric bending machine for tubes, profiles, bars, and flat bars, depending on the rollers used. Equipped with a mechanical top roller adjustment with vernier scale, it ensures repeatable bending precision. Its heavy-duty design guarantees maximum stability during operation. The foot pedal allows easy forward/reverse control, and the machine can work both vertically and horizontally. Maximum bending capacity for round tubes up to 50 mm.
The CORMAK RBM40HV electric bending machine is designed for bending tubes, profiles, rods, and flat bars depending on the rollers used. The machine is equipped with a mechanical top roller adjustment with a vernier scale, making it ideal for bending arcs, circles, spirals, and other curved elements. Its heavy structure ensures excellent stability during operation. The included foot pedal allows convenient left/right drive control, and the machine can operate in both vertical and horizontal positions. Maximum bending capacity for tubes up to 50 mm. It is widely used in metal workshops and on construction sites.
The CORMAK RBM40HV tube and profile bending machine is a precise, three-roller, mandrel-free bender designed for bending steel tubes, rectangular profiles, and solid materials. It enables operation in both vertical and horizontal positions, allowing flexible adaptation to production layouts. Equipped with hardened rolls and a scaled top roller adjustment system, it ensures repeatable bending radii and high wear resistance.
The CORMAK RBM40HV model has been designed for intensive use in industrial environments. The frame is built from thick, rigid steel elements, ensuring resistance to torsion and bending forces. Bending rollers are made of hardened, precision-ground steel with a 40 mm diameter, offering excellent wear resistance. The pressure adjustment system with vernier scale allows precise repetition of bending radii for serial production.
The CORMAK RBM40HV tube and profile bender provides high bending accuracy for both single-piece and series production. The gear transmission with 2.2 kW motor (S6) enables smooth bending of hard materials, such as steel tubes with 2 mm wall thickness. Bidirectional rotation allows easy forming of closed arcs and spiral structures.
The RBM40HV model is a professional tool for the metal industry, dedicated to bending materials of various cross-sections. Ideal for:
| Material: round tube [mm] | 50 × 2 |
| Material: square profile [mm] | 50 × 50 × 2 |
| Material: round bar [mm] | 35 |
| Material: solid rectangular bar [mm] | 35 × 35 |
| Roller diameter [mm] | 40 |
| Motor power [kW] | S1 1.5 / S6 2.2 |
| Power supply | 3-phase, 400 V |
| Dimensions (L × W × H) [mm] | 900 × 850 × 1,700 |
| Weight [kg] | 485 |
