CNC Rebar Arc Bending Machine

Overview

The SKDZWH-36 CNC Rebar Arc Bending Machine is a servo-controlled arc bending solution from Gongda (China Rebar Machinery, chinarebarmachinery.com), built for B2B buyers who need repeatable, programmable large-diameter rebar arcs rather than manual guesswork. It handles bars up to 40 mm in diameter and is programmed through a touch-screen PLC interface, so an operator can store and recall bending sequences instead of resetting the machine by hand for every batch.

Gongda is based in Hefei, Anhui, China, with the factory rooted in the electromechanical works of Hefei University of Technology. The company exports rebar processing machines worldwide, including to Russia, Spain, Latin America, the Middle East, Southeast Asia, and Africa.

Key specifications explained

• Maximum bendable rebar diameter: 40 mm — covers the heavy bar sizes used in bridge, tunnel, and infrastructure work, where smaller benders are not rated.
• Arc bending diameter: R500 and above / unlimited — the machine is not locked to one fixed radius, so you can produce large-radius arcs and continuous curves rather than only tight bends.
• Drive wheel speed: servo controlled — servo regulation keeps the feed rate consistent, which matters for uniform curvature across a batch.
• Motor power: 4KW + 2.5KW (CNC servo) — the main drive and the servo axis are rated separately, giving the torque needed for 40 mm bar without stalling.
• Voltage / frequency: 380V / 50HZ — standard industrial three-phase supply; confirm your site's supply before ordering.
• Control: computer touch screen / PLC programming — parameters are entered and stored digitally, reducing setup time and operator error.
• Dimensions: 1800 × 1500 × 1100 mm — plan floor space and lifting access around this footprint.

Applications

The SKDZWH-36 suits fabrication shops and project sites producing curved rebar for bridges, tunnels, arched structures, ring beams, and large-radius reinforcement cages. Because the arc diameter is adjustable from R500 upward without a fixed upper limit, the same machine can serve multiple drawing requirements in one workshop. It is a practical fit for precast yards, rebar processing centers, and contractors who currently bend large arcs manually or on equipment limited to smaller diameters.

Why buy this model from Gongda

• 40 mm capacity with servo control — a combination aimed at heavy rebar work, not light-duty bending.
• PLC + touch screen — programmable, repeatable output for batch production.
• Adjustable arc radius — R500 and above, with no fixed maximum, giving flexibility across project drawings.
• Factory engineering background — rooted in the electromechanical works of Hefei University of Technology.
• Export experience — machines shipped to Russia, Spain, Latin America, the Middle East, Southeast Asia, and Africa.
