What tube sizes does the MR165 cut?

The MR165 cuts round tube from Ø76 – Ø168, square section up to 60 – 130 mm and wall from 1.2 to 6.0 mm. Larger sizes and heavier walls move up to the next model in the range.

How fast does it cut?

Line speed 60 m/min, and the cut length runs from 2,000 – 12,000 mm. Actual length accuracy depends on the encoder, the clamp and the carriage speed being matched to your line speed.

Which saw blade should I use?

HSS / TCT Ø600. HSS is the economical choice for thin wall and general carbon steel; TCT lasts longer and holds an edge better on harder material and thicker wall.

What does the saw motor size mean?

The saw motor is the one doing the cutting. 22 kW servo on this machine, with the carriage on 22 kW servo and feed on 5.5 kW servo. The three are matched as a set; you cannot upgrade one of them on its own.

Can this saw be added to an existing mill?

Yes. Send us the mill model, the tube OD range and the line speed, and we will confirm the foundation, the power supply and the control interface before you commit.

Is this model available with a twin blade arrangement?

The twin blade coordinate type exists for the same size range and is worth considering if your wall is at the heavy end of the specification. We will tell you honestly which one is the better economic choice for your duty.

MR168 Flying Cold Saw | Ø76 – Ø168, Wall to 7.0 mm

What the MR168 flying cold saw does

One frame, two wall ratings. The MR168 is ordered either as the 6 mm version at 60 m/min or as the 7 mm version at 40 m/min — one millimetre of wall costs a third of the speed, and we would rather show you that trade-off than hide it in a catalogue.

The Ø600 blade and the 1200 mm baseline take this saw into API and heavy mechanical pipe territory, where the section is still large enough that a single pass is the economical choice. The clamp, the feed axis and the chip evacuation are matched to the wall rating you order, so the 7 mm build is not the same machine with a sticker: the hydraulic clamp, the feed motor and the saw drive are all one step up.

Technical specifications

Model	Round tube OD	Square section	Rectangular section	Wall thickness	Line speed	Cut length	Clamping	Saw blade	Saw motor
MR168	Ø76 – Ø168	60 – 130	—	1.2 – 6.0 (6 mm) / 1.5 – 7.0 (7 mm)	60 / 40 m/min	2,000 – 12,000	Hydraulic (-H)	HSS / TCT Ø600	22 kW servo

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 MR168

[(‘What is the difference between the MR168 6 mm and 7 mm versions?’, ‘Wall rating and speed. The 6 mm build runs 60 m/min up to 6.0 mm wall; the 7 mm build runs 40 m/min but takes 7.0 mm. Same frame, heavier clamp and drive on the 7 mm version.’), (‘Which MR168 should I order?’, ‘Order by the heaviest wall you actually cut. If 6 mm covers your product, take the 60 m/min build and keep the cycle time. The 7 mm build is for customers whose specification really goes to 7 mm.’), (‘Is MR168 the same machine as the old MR165?’, ‘Yes — we renamed the model to match its real top diameter. The machine, the frame and the Ø600 blade are unchanged.’)]
