CNC Rebar Bending Machine

Overview

The GJZD6-65CZ CNC Rebar Bending Machine is a heavy-duty, numerically controlled bending solution built for construction companies, rebar fabricators, precast plants, and steel processing service centers. Manufactured by Gongda (China Rebar Machinery, chinarebarmachinery.com) in Hefei, Anhui, China, the machine traces its engineering roots to the electromechanical works of Hefei University of Technology — a background that shapes its mechanical reliability and control precision.

Its core capability is straightforward: CNC-controlled bending of A3 steel up to 65 mm in diameter, supported by a substantial 550 mm working table that handles large bar sizes and long bends with stability.

Key Specifications Explained

• Maximum bendable rebar diameter: A3 steel 65 mm; Grade II threaded steel 55 mm; Grade III threaded steel 50 mm. The stepped ratings reflect the higher yield strength of graded rebar, so buyers should match the rating to the steel actually being processed.
• Working table diameter: 550 mm — the bending platform size that determines the radius and geometry range achievable.
• Spindle speed: 4.5 / 7 rpm, giving two bending speeds for different bar diameters and production rhythms.
• Motor: YEJ132M-4, 8 KW, 1450 rpm. The YEJ series is an electromagnetic braking motor, which supports accurate stopping and repeatable bend angles under CNC control.
• Voltage / frequency: 380 V / 50 Hz — standard industrial three-phase supply. Buyers in other grid standards should confirm compatibility before ordering.
• Dimensions: 1250 × 1100 × 900 mm — a compact footprint relative to its bending capacity, suitable for workshop layouts with limited floor space.

Applications

The GJZD6-65CZ suits high-volume and large-diameter rebar work: foundation and pile cages, bridge and tunnel reinforcement, diaphragm walls, precast element production, and general construction steel fabrication. CNC control reduces dependence on operator skill for repeat bends, improving batch consistency where identical stirrups, hooks, or shaped bars are required in quantity. It is equally applicable to rebar processing plants supplying multiple job sites and to contractors running an in-house fabrication yard.
