Square tube bending machines form tubular profiles into bends and shapes used in furniture frames, handrails, and automotive chassis components. Shijiazhuang Faith Machinery Co.,Ltd offers CNC-controlled square tube benders designed for repeatable precision and efficient setup.
Machine Configuration
The bending cell includes a feed and positioning system, a bending head with interchangeable tooling, and a mandrel or wiper die setup to support the tube interior and minimize wrinkle formation. A post-bend catcher and drop table handle formed parts automatically.
Technical Capabilities
Bend Radius Range: From 1.5× tube side to 5× tube side, accommodating both tight and gentle curves.
Tube Sizes: Square tubes from 12 × 12 mm up to 100 × 100 mm, wall thicknesses from 1 mm to 5 mm.
Bend Angles: Programmable from 0° to 180°, with absolute accuracy within ±0.5°.
Servo-Driven Axes: Provide bend head rotation, clamp and pressure die actuation, and 3‑axis tube positioning.
Control and Automation
A CNC controller with touch‑screen interface stores bend programs for different tube sizes and part geometries. Automatic length measurement and feed positioning eliminate manual setups. A force feedback system monitors bend torque to adapt speed and prevent tube deformation.
Applications
Typical parts include furniture legs, railing assemblies, engine mounts, and structural frames. The machine supports single-bend or multi-bend sequences in one cycle, with optional labeling or notch‑cutting modules integrated downstream.
After‑Sales Support
Faith Machinery provides installation supervision, operator training on CNC programming and tooling change, and preventive maintenance guidance for hydraulic systems and bearings. Spare tool sets and die kits are available to reduce tooling lead times.
