MR32 Flying Cold Saw — Ø7.6 – Ø38 mm, 0.6 – 2.3 mm Wall, up to 120 m/min

What the MR32 flying cold saw does

The everyday small rack saw. Most small ERW lines that make furniture tube, steel props and mechanical pipe are quoted around the MR32, because it covers the whole band without a second cut-off.

Same frame as the MR25 but with a 7.5 kW saw motor and a heavier feed drive, so 2.3 mm wall stops being a special case. The rack drive keeps the cut length stable shift after shift, which matters on structural sizes where every stick is counted. Changeovers are done at the clamp and the controller, not in the drive system.

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 Ø350, 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 MR32

[(‘What sizes does the MR32 cover?’, ‘Round Ø7.6 to Ø38 mm, square 6 to 30 mm, rectangular 20×40 mm, wall 0.6 to 2.3 mm at 120 m/min.’), (‘Is the MR32 available with both clamps?’, ‘Yes. Order MR32-P with the pneumatic clamp or MR32-H with the hydraulic clamp. Below 2 mm wall the pneumatic version is the usual choice; the hydraulic one is for customers who want one clamp type across the whole line.’), (‘How does changeover work between sizes?’, ‘Size change is a clamp and roller change plus a parameter set on the controller. The drive needs no re-tensioning, which is one of the practical differences against a belt machine.’)]
