Both ends in one cycle
Facing, inside chamfer and outside chamfer on both tube ends simultaneously—about twice as fast as a single-side machine.
Bora B2 product overview
Both tube ends chamfered in one cycle
Clean ends make better welds and easier bending.
If you cut tubes to length before bending or welding, the cut ends need chamfering. Burrs, sharp edges and uneven faces cause bad welds, difficult mandrel insertion on bending machines and handling hazards. A double-head chamfering machine does both ends in one cycle—about twice as fast as a single-side machine.
The DuralBend Bora B2 handles inside chamfering, outside chamfering and facing on both ends of the tube simultaneously, in mild steel, stainless, aluminium and copper. Two models are available depending on your diameter range.

Why the Bora B2
Both ends, one cycle, fully electric
Fully electric
No hydraulic circuit: cleaner operation, less maintenance and lower energy consumption.
Servo feed, inverter spindle
Servo-controlled feeding and inverter-controlled spindle speed—on both approach and cutting—as standard.
Quick, safe changeover
Interchangeable grips for different tube sizes, with a safety cover over the cutting area.
Facing and chamfering in one operation
Two Steps Collapsed Into One
Both Bora B2 models work as a facing and chamfering machine: face finishing, inside chamfer and outside chamfer in a single setup, on both ends of the tube at the same time. For shops that previously ran a separate facing operation and then a separate chamfering operation, this collapses two steps into one—cycle time drops, handling drops, scrap drops.
Chamfering blade and die quality is something we've spent a lot of time developing, and it shows in the finish: clean chamfers, consistent results and long tool life. If you also cut tubes to length, the B2 fits a cut-then-chamfer cell, which we can quote together.

Control and drive01 02 03 04
Inverter Speed, PLC Control
The chamfering process runs in two inverter-controlled steps, on a fully electric, PLC-controlled platform you tune from the touchscreen.
Two-Step Cycle
A fast approach to save cycle time, then a slower, adjustable chamfering speed for a smooth finish—both inverter-controlled, so you tune them per material.
Fully Electric Drive
No hydraulic circuit; servo-controlled feeding, cleaner operation and lower energy use.
PLC/HMI Touchscreen
Multi-language interface with automatic and manual modes, and plain, straightforward operation.
Automatic Feeding (Optional)
An optional auto feeder loads tubes continuously for high-volume production with less operator involvement.

Two Bora B2 models
Ø20 to Ø80 mm, both ends at once
Two models cover Ø20 mm to Ø80 mm. Both are fully electric with servo feeding and inverter-controlled spindle speed, and both face and chamfer both tube ends in a single cycle.
- Two chamfering heads — both ends in one cycle
- Fully electric operation, no hydraulic circuit
- Servo-controlled feeding
- Inverter-controlled spindle speed
- PLC and HMI control with touchscreen
- Interchangeable grips and safety cover

Bora B2 Model Comparison
Compare the two Bora B2 models—B2-60 and B2-80.
| Bora B2-60 | Bora B2-80 | |
|---|---|---|
| Tube diameter range | Ø20 – Ø60 mm | Ø20 – Ø80 mm |
| Motor power | 7.4 kW | 11 kW |
| Chamfering heads | 2 — one per tube end | 2 — one per tube end |
| Drive | Fully electric, no hydraulics | Fully electric, no hydraulics |
| Feeding | Servo controlled | Servo controlled |
| Spindle speed | Inverter controlled | Inverter controlled |
| Operations per cycle | Facing, inside chamfer, outside chamfer — both ends | Facing, inside chamfer, outside chamfer — both ends |
| Materials | Mild steel, stainless steel, aluminium, copper | |
Both models work with mild steel, stainless steel, aluminium and copper. Automatic tube feeding is available as an option. If you only ever chamfer one end, the more compact single-side Bora B1 may suit better.
