Multi-Axis CNC Tube Bending Machine
High speed pipe bender for metal tubes used in automotive, aerospace and industrial sectors, covering tube diameters from 30mm to 100mm
These multi-axis CNC tube bending machines are designed for precise left- and right-side bending and can be used in automated production setups. They allow short straight ends after the final bend, kept below 1.2D, which helps reduce material usage and overall production costs.
Multi-axis coordinated operation supports high production efficiency and allows dual-head configurations with up to eight tooling stacks, combined with automatic process simulation. A full-servo drive system, together with high-precision transmission components, ensures repeat positioning accuracy of up to 0.02 mm.
- Angle: 13-axis full-servo bending ensures accurate control at any bending angle, with angular accuracy within 0.05° and feeding accuracy up to 0.05 mm.
- Circularity: Multi-core mandrel bending combined with synchronized lubrication helps maintain stable tube roundness during the bending process.
- Thinning: Wall thinning is managed by coordinating the bending motion with auxiliary pushing and mandrel movement. Push-feed compensation and synchronized lubrication help keep wall thickness more consistent and improve forming stability.
- Forming: Three-dimensional bending accuracy is controlled within ±0.5 mm, ensuring consistent tube geometry and dimensional stability.
