MC425 NC Tube Cutting Machine – Product Description
The 425 NC cutting machine has a maximum cutting capacity of 160 mm round tubes, 130×130 mm square tubes, and solid bars, and is designed for shipbuilding, structural steel, oil and gas, and other heavy-duty applications requiring the machining of large-sized materials.
The CNC hydraulic feed system provides smooth and consistent cutting pressure, while the Φ450 mm high-speed steel inserts provide the high torque required for efficient cutting of thick-walled stainless steel and alloy steel. The 730 kg cast iron body minimizes vibration, maintaining a repeatability of ±0.1 mm even during long periods of continuous production.
If your machine tool struggles with machining large-diameter tubes or thick-walled materials, simply replacing the inserts with larger ones won’t solve the problem. Heavier machines equipped with more powerful hydraulic feed systems achieve more stable cutting, longer insert life, and higher productivity.
MC350NC CNC Tube Cutting Machine Feature Box
Heavy-Duty Hydraulic Clamping
The 2.2KW hydraulic pump gives you strong, even clamping on round tube, square tube, irregular profiles, and solid bar. You do not need to tighten the material by hand, and the workpiece stays stable throughout the cut.
Our advice: When cutting thick-wall or heavy material, stable clamping matters as much as motor power. It helps you reduce material movement, crooked cuts, and rework.
Dual-Speed 4.5/5.5KW Motor
You can use low speed for stainless steel, alloy steel, and solid bar, where higher torque is needed. High speed is better for carbon steel and aluminum, helping you keep production moving efficiently.
Our advice: Do not use one speed for every material. The correct speed reduces blade heat, improves cut quality, and makes your cycle time more predictable.
Φ450mm HSS Blade Capacity
The MC425NC supports a Φ450mm HSS blade, giving you more cutting capacity for large and thick-wall materials. The larger blade runs at a lower cutting speed, which helps control heat and reduce blade wear.
Our advice: For heavy-wall stainless steel, a larger blade is not only about cutting size. It also gives you more stable performance and longer blade life.
Automatic Linear Guide Lubrication
The guide rails lubricate themselves during operation, so you do not need to grease them every day. This keeps the feed movement smooth and reduces wear over long production runs.
Our advice: Consistent guide movement protects both the rail system and the blade. Over thousands of cycles, this helps you reduce maintenance and keep cutting accuracy stable.
Cut 160mm Pipe — The Diameter That Stops Other Machines
Your MC315 caps at 100mm. Your MC350NC runs out at 130mm. Then the 160mm order lands.
The MC425NC NC pipe cutting machine handles Φ140-160mm round pipe at 90° and 120×120-130×130mm square tube — one pass. No rotating the workpiece. No repositioning. No “we can’t cut that” calls to customers.
The 5.5KW motor with Φ450mm blade delivers the torque large-diameter, thick-wall pipe demands. Low speed: cutting force for 6mm+ wall stainless. High speed: carbon steel at production pace. Your capacity chart expands overnight — and so does your customer list.
Why Oil & Gas Shops Choose This NC Pipe Cutting Machine
Oil and gas means schedules, specs, and inspectors. Pipe spools and pressure-rated assemblies don’t leave room for “close enough.”
The MC425NC NC pipe cutting machine for oil and gas delivers ±0.1mm accuracy, CE/ISO 9001 documentation, and the capacity for schedule 80-160 pipe that upstream projects demand.
When an EPC inspector brings calipers to your shop, the MC425NC passes. No rework. No rejected batches.
Blade Selection Guide: Get the Most from Your NC Pipe Cutting Machine
The MC425NC accepts four blade sizes — each for a different cutting scenario. The right blade means faster cycles, longer life, cleaner cuts.
- Φ300mm blade — Thin-wall tube (≤3mm). Highest RPM, fastest cycle. High-volume carbon steel and aluminum where speed beats torque.
- Φ350mm blade — General-purpose. Balanced speed and torque for medium-wall pipe (2-5mm). Daily driver for mixed-material shops.
- Φ400mm blade — Heavy-wall and larger diameters. More teeth in contact, better heat distribution. Schedule 40-80 pipe, diameters above 100mm.
- Φ450mm blade — MC425NC exclusive. Maximum torque, lowest RPM. Schedule 80-160 pipe, solid bar, thick-wall stainless, alloy steels. Slow, steady, powerful.
All blades are standard HSS, Φ32mm bore — available from any industrial supplier. No proprietary consumables.
Applications of NC Pipe Cutting Machine
Shipbuilding & Marine Piping
Large marine pipes require accurate and stable cutting before welding.
The MC425NC handles 100–160mm pipes with hydraulic clamping to keep the material secure and produce clean, repeatable cuts.
Our advice: If you cut large pipes every day, stable clamping helps reduce rework and improves welding quality.
Oil & Gas Pipeline
Pipeline fabrication demands accurate cuts for reliable weld joints.
The MC425NC cuts large-diameter carbon steel and alloy pipes with smooth, burr-free ends, reducing grinding and improving production efficiency.
Our advice: Cleaner cuts mean less preparation before welding and more consistent pipe assembly.
Heavy Steel Structures
Large square tubes and thick-wall sections require more than just a powerful motor.
The MC425NC combines a heavy-duty machine body, hydraulic clamping, and a large blade to keep materials stable during cutting, making it ideal for structural frames, handrails, and construction projects.
Our advice: If your current machine vibrates on heavy materials, a more rigid machine will improve both cut quality and blade life.

What is the maximum cutting capacity?
The MC425NC cuts round tubes up to 160mm and square tubes up to 130×130mm.For larger materials or special applications, we can recommend a higher-capacity solution.
Can MC425NC cut solid steel bars?
Yes.Its 730kg machine body, hydraulic feed, and Φ450mm HSS blade make it suitable for cutting solid bars and thick-wall materials with stable performance.
MC350NC or MC425NC?
The main difference is cutting capacity.
Choose MC350NC for tubes up to 130mm. Choose MC425NC if you regularly cut 130–160mm pipes or thick-wall materials.
Our advice: If your business is growing into larger pipe sizes, the MC425NC gives you more flexibility without upgrading to a full CNC machine.
Can I test my own material?
Yes.You can send us your samples, and we will perform test cutting and provide videos and measurement results before you place an order.
Do you provide complete production lines?
Sure，Besides pipe cutting machines, we also supply chamfering machines, tube bending machines, and complete tube processing solutions to help you build an efficient production line.
