On a small-tube line the cut-off is usually the bottleneck: the mill can form tube faster than a friction saw can cut it. A high speed flying cut-off with a light carriage and a cold saw blade keeps up with the mill at 120 m/min and still delivers a square, burr-free end.
Where It Fits
- Furniture, bicycle and decorative tube lines from ø8 mm.
- Automotive and heat-exchanger tube where the cut end is welded next.
- Galvanized and coated tube, where a friction saw would burn the coating.
- Retrofit onto an existing mill whose hot saw limits line speed.
MR25 and MR32 cover ø8–38 mm at up to 120 m/min; for larger tube we move to the orbital and gantry saws. Each unit is run on our own bench with tube before shipment.
Cycle time is the hidden limit
A flying cut-off must finish cutting, retracting and returning before the line produces the next length. At 90 m/min with 6 m lengths, that is about four seconds per cycle. A saw that needs five seconds becomes the bottleneck of a fast mill, no matter how good its cut quality is.
| Line speed | 6 m length | Cycle available |
|---|---|---|
| 30 m/min | 12 s | Comfortable for most saws |
| 60 m/min | 6 s | Requires servo tracking |
| 90 m/min | 4 s | Requires fast carriage and short stroke |
| 120 m/min | 3 s | Dual-head or specialised design |
High speed without losing the cut face
Speed comes from three things: a light, rigid carriage; a short, controlled blade stroke; and a clamp that grips without crushing the tube. Increase line speed without those and the cut face degrades before the cycle time improves.
What to specify
- Maximum line speed and the cut length range you sell.
- Tube diameter and wall range, including the thinnest wall.
- Required length tolerance and burr height.
- Whether the saw must run unattended through a coil.
