MR76 Flying Cold Saw | Ø32 – Ø89, 1.0 – 4.0 Wall

What the MR76 flying cold saw does

The saw the whole range is judged by, and the one we quote most. Wall 4.0 mm at Ø89 is exactly where a rack machine is the economical answer, and the MR76 was designed around that duty.

The frame is deeper than the MR60 and the saw motor steps to 15 or 22 kW depending on the wall range you actually run. At 90 m/min the cut cycle is still quick, but the point of this machine is not the top speed — it is holding a square, bright cut on structural wall, shift after shift, without the clamp marking the tube. It is offered in light, standard and heavy-duty builds, separated by wall range rather than by frame size.

Technical specifications

Model	Round tube OD	Square section	Rectangular section	Wall thickness	Line speed	Cut length	Clamping	Saw blade	Saw motor
MR76	Ø32 – Ø89	25 – 70	45×90	1.0 – 4.0	90 m/min	2,000 – 12,000	Pneumatic (-P) or hydraulic (-H)	HSS / TCT	15 – 22 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, 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 MR76

[(‘Why is the MR76 limited to 90 m/min when the MR76T does 120?’, ‘The heavier carriage needed for 4 mm wall cannot accelerate as fast. The 30 m/min difference is physics, not a derating, and on lines that run below 90 anyway it costs nothing.’), (‘What does the -P and -H after MR76 mean?’, ‘The clamp. MR76-P carries a pneumatic clamp: quick, light, right for thin and medium wall. MR76-H carries a hydraulic clamp: higher clamping force, steady holding, the choice from about 2.5 mm wall and for larger diameters. You order the saw with the clamp already matched to your product.’), (‘Can one MR76 cover both furniture tube and structural sizes?’, ‘Yes, if the duty stays inside 4.0 mm wall. We size the saw motor and the clamp against the heaviest product in your mix, not against the largest diameter.’)]
