Product Description
The GM-50NCB is a numerically controlled (NC) hydraulic pipe bender designed for fabrication shops, maintenance departments, and on-site installation teams that need workshop-level bending accuracy outside a fixed production line. Built around a fully hydraulic drive system and a PLC control unit with touch-screen input, the machine bends round, square, and rectangular metal profiles without manual angle measurement. Its 2.0-ton frame and 3,500 mm packaged length accommodate mild steel round tube up to 50 × 3 mm, while an imported angle encoder holds bending repeatability to ±0.10°.
Unlike hand-lever benders, the GM-50NCB uses hydraulic clamping, a guide die, an anti-crease device, and an assist-push mechanism to reduce ovality and wall thinning on thin-wall tubing. The PLC stores bending programs, and the touch panel allows operators to set angle, feed position, and speed parameters directly. This makes the unit suitable for job-site repair work, custom railing fabrication, and small-batch production where a full CNC cell would be oversized for the workload. The machine can be relocated between workshops or shipped to installation sites with standard forklift or crane handling.

The repeatability of an NC bender depends on the quality of its hydraulic and electronic components. The GM-50NCB pairs a 5.5 kW system motor with a 19 L hydraulic pump delivering a maximum working pressure of 16 MPa. Key imported components include a Mitsubishi PLC, Yuken hydraulic valves, a Nemicon angle controller, and a Weinview touch screen. Contactors are supplied by Schneider, and the hydraulic motor is available with either a Siemens (BEIDE) or Runmali unit.

The angle encoder feeds real-time position data back to the PLC, which adjusts the bending arm to maintain the programmed angle across repeated cycles. This component selection also simplifies spare-part sourcing for industrial clients operating in regions where these brands are already supported.
The GM-50NCB serves metal fabrication shops, HVAC contractors, furniture manufacturers, and agricultural equipment builders that process mild steel, stainless steel, and light alloy tubing. With a minimum bending radius of 20 mm and a maximum standard bending radius of 250 mm, it covers common handrail, exhaust, roll-cage, and structural bracket geometries. The 3,200 mm through-effective distance allows long tube sections to pass through the machine without pre-cutting to short lengths.
For business buyers evaluating on-site bending options, the GM-50NCB occupies a middle ground between hand tools and fixed CNC cells: it delivers hydraulic power and NC angle control in a package that can be moved between job sites. Standard safety features include emergency stop controls and machine guarding, and the unit operates on standard industrial three-phase power.
The machine bends mild steel round tube up to 50 × 3 mm, stainless steel tube up to 35 × 2 mm, and mild steel square tube up to 35 × 35 × 2 mm. Solid mild steel round bar up to 18 mm and square bar up to 16 × 16 mm can also be processed.
No. The GM-50NCB uses a fully hydraulic drive and PLC control with a touch-screen interface. The operator inputs bending parameters, and the machine executes the bend under hydraulic power. The "manual" designation refers to its NC semi-automatic operating mode rather than hand-lever operation.
The rated bending angle precision is ±0.10°, controlled by an imported Nemicon encoder. The maximum bending angle is 190°.
Imported components include the Mitsubishi PLC, Yuken hydraulic valves, Nemicon angle controller, Weinview touch screen, and Taiwan-manufactured oil-way board and switching power supply. The hydraulic motor can be configured with a Siemens (BEIDE) or Runmali unit.
The packaged dimensions are 3,500 × 800 × 1,300 mm, and the machine weight is 2.0 tons. Forklift or crane handling is required for relocation.
