What the MR127T flying saw does
The largest saw in the belt range. Past Ø140 the carriage mass makes the belt uneconomical, so this is where the high-speed series stops and the rack series takes over.
The MR127T is quoted where the mill runs fast and the tube stays under 5.5 mm wall: water pipe, large structural section, and API product in the smaller diameters. The carriage is the heaviest we put on a belt, which is why the rails and the belt section are unique to this model rather than shared with the MR114T.
Technical specifications
| Model | Round tube OD | Square section | Wall thickness | Line speed | Cut length | Saw blade | Carriage motor | Saw motor | Feed motor |
|---|---|---|---|---|---|---|---|---|---|
| MR127T | Ø63 – Ø140 | 50 – 110 | 1.2 – 5.5 | 120 | 2,000 – 12,000 | HSS / TCT | 15 kW servo | 30 kW | 4.4 kW servo |
What comes with the machine
- Belt-driven carriage — toothed belt on a hardened rail, tensioned at the factory and checked on site.
- Clamping — pneumatic on the small sizes, hydraulic from Ø76 upwards.
- Saw head — HSS / TCT, with blade tensioner and coolant arrangement.
- Control — servo drive and a controller that holds cut length across the full speed range.
- Guard and extraction — enclosed cutting with chip extraction.
Where it is normally installed
The saw sits on the exit side of the sizing stand, where the tube has reached its final dimension and is still moving at line speed. That position is what makes the cut square and the length accurate: the carriage tracks the moving tube instead of stopping it. We confirm the station layout against your mill arrangement, including the run-out table and where the cut tube goes next.

Questions buyers ask about the MR127T
What happens above Ø140?
The belt carriage becomes too heavy to accelerate to a useful speed, so we quote the MR127 or the MR168 from the rack range instead.
Can the MR127T cut 6 mm wall?
Not at production speed. The published limit is 5.5 mm; above that the cut time and the blade wear stop being economical on a belt machine.
How long is the carriage rail?
It depends on the cut length you specify. Send the cut length range and we will size the rail and confirm the floor space on the layout drawing.
