Pneumatic Pipe Chamfering Machine — DJ80NC vs DJ120NC Technical Comparison
You have a decision to make: DJ80NC or DJ120NC. Both are single-head pneumatic chamfering stations. Both cut inner, outer, and face chamfers in one clamping cycle. The difference is capacity — and whether that extra 40mm of pipe diameter matters to your order book.
| Parameter | DJ80NC Pneumatic | DJ120NC Pneumatic | What It Means for Your Shop |
|---|---|---|---|
| Pipe capacity | Ø8mm – Ø80mm | Ø10mm – Ø120mm | DJ80NC covers furniture tube, handrail, and automotive pipe; DJ120NC adds structural and large-diameter capability |
| Solid bar capacity | Ø5mm – Ø30mm | Ø8mm – Ø40mm | DJ80NC doubles as a bar chamfering station; one machine for pipe and solid stock |
| Wall thickness | 0.3mm – 4.0mm | 0.5mm – 8.0mm | DJ120NC handles heavy-wall pipe the DJ80NC physically cannot cut; if 80% of your work is under 4mm, the DJ80NC is enough |
| Motor | 380V 1.5KW | 380V 2.2KW | Both run on standard industrial three-phase; DJ120NC’s extra 0.7KW delivers the torque for 8mm wall cuts |
| Cycle time | ~3.5 seconds per end | Variable (belt-driven RPM) | DJ80NC optimized for raw speed; DJ120NC trades a slight cycle-time increase for broader material flexibility |
| Weight | 220kg | 300kg | Both are stable in production and movable with a pallet jack — no foundation bolts, no crane |
| Dimensions | 800 × 850 × 900mm | 800 × 1050 × 1100mm | DJ80NC fits tighter layouts; DJ120NC needs slightly more vertical clearance |
| Pneumatic system | Miaode cylinder + solenoid valve | Miaode cylinder + solenoid valve | Japanese-design pneumatics on both models; consistent feed pressure, cycle after cycle |
| Tooling | Custom carbide inserts | Standard tool head (3/8″–2.0″ O.D.) | Both complete inner + outer + face in one pass; DJ120NC uses industry-standard tool sizing for easier sourcing |
| Price range | 1,300–1,800 | 1,500–2,200 | ~20% premium buys you 50% more diameter capacity and double the wall thickness range |
Suggestion: If your daily volume is 80% tubes under 80mm with walls under 4mm, the DJ80NC pneumatic pipe chamfering machine handles your workload at the lower price point. If you have that 20% of large-diameter or thick-wall orders — or you expect your order mix to shift upward — the DJ120NC saves you from buying a second machine next year. Spend 20% more now, or potentially 100% more later.
Pneumatic Pipe Chamfering MachineProduct Description
The DJ80NC and DJ120NC are single-head pneumatic chamfering stations built for shops that need hydraulic-grade consistency at pneumatic speed — without the cost, weight, or maintenance of a hydraulic system.
Each air pipe chamfering machine completes inner chamfer, outer chamfer, and end face in one clamping cycle. A dual-speed pneumatic feed advances the tool head rapidly to the workpiece, then shifts to a controlled slow cut — fast approach, clean finish, no deformation on thin-wall tube down to 0.3mm.
Both models use belt-driven variable RPM. Change spindle speed by moving the belt to a different pulley set — low RPM for stainless (prevents burning the tool), high RPM for aluminum (fast cut, no galling).
The Miaode pneumatic system delivers repeatable feed pressure, so chamfer depth stays consistent from part one to part one thousand. This is a purpose-built pneumatic tube chamfering machine, not a repurposed lathe with a chamfer attachment. The cast-iron head absorbs vibration. The carbide tooling holds geometry. The auto-clamp and auto-feed cycle runs with one pedal press.

Key Benefits of Our Pneumatic Pipe Chamfering Machine
Dual-Speed Feed — Rapid Approach, Controlled Cut
If you need speed, but you also need a stable finish. The dual-speed pneumatic feed quickly approaches the tube, then slows down for the cutting process. This prevents tube deformation, vibration, and poor chamfer quality — especially when you work with thin-wall stainless steel tubes.
One-Pass Three-Side Chamfering
You can complete inner chamfer, outer chamfer, and end-face chamfering in one cycle. No repositioning, no repeated operations. This helps you reduce labor time, improve consistency, and keep every tube end with the same quality.
Adjustable Speed for Different Materials
Different materials require different cutting speeds. The belt-driven RPM adjustment allows you to quickly optimize the machine for stainless steel, aluminum, copper, and steel tubes. You can switch materials without complicated programming or electrical adjustments.
Auto Clamp + Auto Feed — Simple Operation
Your operator only needs to load the tube and press the pedal. The machine automatically clamps, cuts, retracts, and releases the part. This reduces operator skill requirements and avoids quality differences caused by manual operation.
3.5 Seconds Per End — More Production, Less Labor
Manual tube filing is slow and inconsistent. When you process hundreds of tube ends every day, labor time and quality issues quickly add up.
With the pneumatic pipe chamfering machine, one cycle takes about 3.5 seconds, allowing you to process 800+ tube ends per hour. You reduce manual work, lower labor costs, and keep production moving faster.
More importantly, every tube gets the same chamfer depth, angle, and finish. You avoid inconsistent quality, rework, and customer complaints caused by operator fatigue.
If you process more than 200–300 tube ends daily, automatic chamfering usually delivers a clear return by saving labor hours and reducing rejected parts.
DJ80NC or DJ120NC — Which Pneumatic Pipe Chamfering Machine Fits You?
Choose based on your actual production needs, not just future possibilities.
- DJ80NC: Ideal for most small and medium tube applications, handling up to Ø80mm pipes.
- DJ120NC: Better for larger tubes, thicker walls, and customers requiring Ø80–120mm capacity.
Our suggestion:
Review your orders from the past 6–12 months. If most tubes are below Ø80mm, DJ80NC is the cost-effective choice. If larger tube sizes are becoming more common, investing in DJ120NC avoids limitations later.
One Machine for Stainless Steel, Aluminum, and Steel Tubes
Different materials require different cutting conditions. Stainless steel needs lower speed to protect the tool, while aluminum requires higher speed for a cleaner finish.
The belt-driven RPM adjustment allows you to quickly change cutting speed without complicated programming. Combined with dual-speed feed, you can process different materials with stable chamfer quality.
Practical advice:
For mixed production environments, choose a machine that adapts to different materials. It helps you reduce tool wear, avoid surface defects, and maintain consistent results across every batch.
Pneumatic vs Hydraulic — Choose the Right Machine for Your Tube Work
When choosing between pneumatic and hydraulic chamfering machines, the key question is not which one is stronger — it is which one matches your production needs.
More in line with your production needs
A Pneumatic Pipe Chamfering Machine is ideal for most tube processing applications. It provides a faster cycle time of around 3.5 seconds per end, lower maintenance without hydraulic oil or pumps, and easy installation with standard workshop air supply (0.6–0.8 MPa).
Compared with hydraulic models, pneumatic machines offer a more affordable solution for regular tube production. You can reduce operating costs, simplify machine maintenance, and improve daily processing efficiency without complex systems.
If you mainly process furniture tubes, automotive pipes, handrails, HVAC tubes, or fitness equipment components, pneumatic is usually the better choice. Hydraulic machines are only recommended for 10mm+ thick-wall pipes that require maximum cutting force. For most tube manufacturers, speed, consistency, and reliability are more important than extra power.
Automotive, Furniture & Industrial Tube Applications
The Pneumatic Pipe Chamfering Machine is designed for high-volume tube processing where speed and consistency matter. It provides clean inner, outer, and face chamfering for applications including automotive exhaust, fitness equipment, steel furniture, and motorcycle components.
For automotive and fitness equipment manufacturers, the machine helps you achieve smooth weld preparation, stable powder coating results, and consistent tube quality. The 3.5-second cycle time keeps up with production lines while reducing manual grinding and rework.
For furniture and motorcycle tube processing, the machine ensures every tube end has the same chamfer profile. You can improve assembly accuracy, reduce sharp edges, and maintain reliable quality from the first part to the last.
