MR50 Flying Cold Saw — Ø20 – Ø63.5 mm, 0.8 – 3.0 mm Wall, up to 120 m/min

What the MR50 flying cold saw does

The volume size of the rack range. Ø51 to Ø63.5 is the band that furniture, ventilation and galvanising lines all sell, and the MR50 was built to sit at the end of exactly those lines.

A Ø400 blade and an 11 kW saw motor carry the full 3.0 mm wall at this diameter without the cut going blue. The carriage runs on a machined rack bed, so the length tolerance holds even when the saw has been working a double shift. Most customers order it with the pneumatic clamp for speed; the hydraulic clamp is available when the product mix includes heavier sections.

Technical specifications

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 Ø400, 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.
