MR273 Flying Cold Saw — Ø102 – Ø273 mm, 2.5 – 8.0 mm Wall, up to 40 m/min

What the MR273 flying cold saw does

The ceiling of the single-blade range. Ø273 with 8 mm wall is where one blade, one cut, one machine still makes sense — and where every extra millimetre of wall belongs to the twin-blade milling saw in the next range.

The MR273 shares the heavy end of the rack family: 30 kW cutting motor, servo carriage, hydraulic clamp, a 4,000 to 12,000 mm cut length window for transmission-type product. Customers choose it over the twin-blade machine when their wall stays inside 8 mm and they want the simpler, cheaper single-pass machine. When the specification pushes past 8 mm, we send them one page over — the same diameter number with an M after it, cutting 12 mm on two blades.

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 MR273

[(‘What is the difference between MR273 and MR273M?’, ‘Blades and wall. The MR273 is single blade, up to 8.0 mm wall. The MR273M is the twin-blade milling machine, up to 12.0 mm. Same diameter, two machines, and the wall you need decides which one we quote.’), (‘Is MR273 available with a pneumatic clamp?’, ‘No — at this size the hydraulic clamp is the only configuration we supply: MR273-H.’), (‘What products run through an MR273?’, ‘Structural tube to Ø273, water transmission pipe and heavy mechanical pipe, typically on HG273 and HG325 class mill lines.’)]
