MR219 Flying Cold Saw | Ø89 – Ø219, 2.0 – 8.0 Wall

What the MR219 flying cold saw does

The second-largest single-blade saw we build. Ø219 structural tube, piling pipe and medium transmission line all land here, and 8 mm wall is the ceiling of what one blade should be asked to cut economically.

Everything about the MR219 is sized around the 8 mm ceiling: a 30 kW saw motor, a servo carriage with the mass to hold the cut square, and a hydraulic clamp that does not let the tube roll under torque. At 40 m/min the machine is deliberate rather than fast — at this diameter the cut length tolerance and the burr side are what the customer inspects, and that is where the rack drive earns its keep.

Technical specifications

Model	Round tube OD	Square section	Rectangular section	Wall thickness	Line speed	Cut length	Clamping	Saw blade	Saw motor
MR219	Ø89 – Ø219	70 – 150	—	2.0 – 8.0	40 m/min	2,000 – 12,000	Hydraulic (-H)	HSS / TCT Ø600	30 kW

What comes with the machine

Rack-driven carriage — hardened gear rack and steel pinion, the cutting torque goes through the tooth, not through friction.
Clamping — pneumatic (-P) or hydraulic (-H), built into the model you order.
Saw head — HSS / TCT Ø600, with blade tensioner and coolant arrangement.
Control — servo feed and a controller that holds cut length across the full speed range.
Guard and extraction — enclosed cutting with chip extraction.

How the -P / -H clamp choice works

Every model in this range is ordered with the clamp written into the model number: -P for the pneumatic clamp (fast, light, thin and medium wall) or -H for the hydraulic clamp (high force, steady holding, heavy wall and large diameter). At the smaller sizes -P is the normal quotation; from around 3 mm wall and upwards the hydraulic clamp becomes the configuration we recommend, and on the largest models it is the only one we supply.

Where it is normally installed

The saw sits on the exit side of the sizing stand and tracks the moving tube, so the cut stays square and the length stays accurate without stopping the line. We confirm the station layout against your mill arrangement, including the run-out table and the tube handling after the cut.

Questions buyers ask about the MR219

[(‘What wall can the MR219 cut?’, ‘Up to 8.0 mm. That is the honest ceiling of single-blade cutting at this diameter; above it we quote the twin-blade milling machine from the profile milling range.’), (‘What is the MR219 normally paired with?’, ‘HG165 and HG219 mill lines making structural tube, piling pipe and water transmission pipe in the Ø89 to Ø219 band.’), (‘Is the clamp pneumatic or hydraulic?’, ‘Hydraulic — MR219-H is the configuration. At 8 mm wall a pneumatic clamp is not a realistic option.’)]
