Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of 2000w tube cutting laser machine in China. Please feel free to buy CE approved machinery made in China here from our factory. All customized machines are with high quality and competitive price.
A 2000W tube cutting laser machine is a CNC-controlled system that uses a 2kW fiber laser source to cut through metal pipes and tubes. The laser generates a beam at 1080nm wavelength, delivered through an optical fiber cable to a cutting head. The beam is focused to a spot diameter of 0.1–0.3mm, producing power density sufficient to melt or vaporize metal at the point of contact. Assist gas-nitrogen, oxygen, or compressed air-ejects the molten material from the kerf. The machine holds the tube in rotating chucks, coordinates chuck rotation with cutting head movement along the tube axis, and follows a tool path generated from CAD data. It performs cutting, hole drilling, slotting, and contouring in a single clamping cycle.
The production process of the 2000W Tube Cutting Laser Machine
The manufacturing process involves: inspecting raw materials, cutting steel plates, welding bed frames, stress relief annealing, milling mounting surfaces, assembling components, installing and aligning the optical system, wiring electrical components, setting control system parameters, conducting a 48-hour continuous run test, performing factory inspection, packing, and finally, shipment.
Common Failure Modes
Dross on cut edge – Insufficient gas pressure or unstable flow. Check gas supply (0.5–2.5MPa). Check for leaks or blockages in the gas line. Verify solenoid valve operation.
Rough cut surface – Focus position shifted. Check for impact damage to cutting head. Inspect protective window and focusing lens for contamination. Verify cooling system operation (thermal drift).
Tube slippage – Insufficient chuck clamping force or worn jaws. Check hydraulic/pneumatic system pressure. Inspect jaw contact surface for oil contamination or wear. Replace jaws when wear exceeds 0.5mm depth.
Frequent lens damage – Impure assist gas or insufficient flow causing spatter to reach the lens. Check gas purity (oxygen ≥99.5%, nitrogen ≥99.99%). Verify gas flow rate meets process requirements.
Laser power drop – Laser source overheating. Check cooling system operation. Verify coolant temperature. Inspect chiller for proper heat dissipation.

faq
Can this 2000W Tube Cutting Laser Machine cut stainless steel without discoloration?
Yes, with nitrogen assist gas at correct pressure and flow rate. Discoloration (oxidation) occurs when oxygen is present. Nitrogen prevents oxidation, leaving the cut edge silver-white. Cut edge typically requires no cleanup before welding.
Can this machine run unattended?
With automatic loading and unloading systems, yes. Manual loading requires operator presence. The machine can run continuously with automatic tube feeding, scrap removal, and part sorting. For manual operation, the primary operator task is tube loading and finished part unloading.
What is the acceptable tube straightness tolerance for this machine?
The machine can compensate for tube curvature up to approximately 3mm per meter. For tubes with greater curvature, the machine will still cut, but the cut line will follow the tube's curve rather than the programmed straight line. This results in parts with consistent angular orientation relative to the tube's centerline but with curvature preserved in the finished part. For applications requiring straight finished parts, the tube straightness should be within 1mm per meter.
Can the machine cut oval or rectangular tubes with varying wall thickness?
The machine can cut any tube cross-section that can be held in the chucks and rotated. However, cutting parameters must be set for the thickest wall section because the laser power is constant regardless of tube orientation. The machine cannot adjust power based on the tube's rotational position. This is a limitation for tubes with varying wall thickness-you either cut at lower speed to handle the thickest section, or you accept burn-through on thinner sections.
