튜브 레이저 절단은 튜브를 관 레이저 절단 기계, 튜브를 자동으로 센터링하고 절단 파라미터를 설정한 후, 집속된 레이저 빔을 사용하여 프로그램된 경로를 따라 튜브를 정밀하게 절단합니다.

이 공정은 CNC 제어, 회전 동작 및 레이저 기술을 결합하여 금속 튜브와 파이프에 대해 정밀하고 버(burr) 없는 절단을 구현합니다.

레이저 튜브 절단이란 무엇입니까?

레이저 튜브 절단은 집속된 레이저 빔을 사용하여 금속 튜브와 파이프를 절단, 슬롯 가공, 드릴링 또는 성형하는 공정입니다. 평판 절단과 달리, 레이저 튜브 절단에는 다음이 필요합니다:

  • 정밀한 튜브 고정 및 회전
  • 튜브 변형을 보정하는 자동 센터링
  • 선형 축과 회전 축의 정밀한 동기화

튜브 레이저 절단기는 원형 튜브, 사각 튜브, 직사각형 튜브 및 특수 형상 프로파일을 높은 반복 정밀도와 최소한의 소재 낭비로 가공할 수 있습니다.

1. 튜브 레이저 절단 전 준비 단계

Proper preparation is critical for safety, accuracy, and cutting quality.

Check the Work Area

  • Ensure the working area is clean and free of obstacles

  • Confirm all safety guards and protective covers are in place

Inspect the Machine

  • Check the laser source, chiller water temperature, and gas pressure
  • Inspect the cutting nozzle and focusing lens for contamination or damage
  • Confirm all electrical and pneumatic connections are normal

Prepare Materials and Tools

  • Verify tube material, diameter, thickness, and length
  • Prepare drawings or cutting programs in advance

2. Power-On and Machine Startup

Correct startup order protects the machine and ensures stable operation.

Standard Startup Sequence

  1. Main power switch
  2. Voltage stabilizer
  3. Emergency stop reset
  4. CNC control system
  5. Servo system
  6. Water chiller
  7. Laser source

Once the control system finishes initialization, perform a homing operation to reset all axes to their reference positions

3. Drawing and Programming for Tube Laser Cutting

Create or Import Tube Cutting Drawings

Using professional tube cutting software (such as TubesT):

  • Draw parts directly or import existing CAD files

  • Define tube type (round, square, rectangular, etc.)

  • Enter tube dimensions and wall thickness

Define tube type

Process and Nesting Setup

  • Define cutting paths, pierce points, and lead-ins
  • Apply cutting technology parameters
  • Perform automatic nesting to optimize material usage

Export the completed task as a cutting program for the machine.

4. Machine Calibration and Debugging

Before cutting, accurate calibration is essential.

Capacitive Calibration

With the tube clamped in the chuck:

  • Perform nozzle capacitance calibration
  • Ensure stable height control during cutting

B-Axis and Chuck Calibration

  • Calibrate the B-axis center
  • Check chuck clamping force and support alignment
  • Ensure smooth tube rotation without slipping

5. Loading and Centering the Tube

Tube Loading

  • Load tubes manually or using an automatic loading system
  • Clamp the tube securely with the chuck

Automatic Centering

  • Run the automatic tube centering function
  • The system detects tube deformation and calculates offset values
  • This ensures the laser cutting head stays aligned with the tube center

Accurate centering is a key advantage of modern tube laser cutting machines and directly affects cutting precision.

6. Set Laser Cutting Parameters

Laser cutting parameters must be adjusted according to material and thickness.

Key Parameters Include:

  • Cutting speed (m/min)
  • Nozzle height (mm)
  • Assist gas type (air, oxygen, nitrogen)
  • Gas pressure (BAR)
  • Peak power (%)
  • Duty cycle (%)
  • Focus position (mm)

Tip for beginners: Always start with recommended parameters and perform a short test cut before mass production

7. Start the Laser Tube Cutting Process

Trial Cutting

  • Click the “Start” button to begin cutting
  • Perform a short test cut
  • Check edge quality, burrs, and dimensional accuracy

Batch Production

Once the result is confirmed:

  • Enable cycle processing mode
  • Set production quantity and interval time
  • Monitor the cutting process in real time

During cutting, observe:

  • Stability of cutting sparks
  • Smooth removal of scrap
  • Gas pressure and machine status

8. Unloading and Shutdown

After cutting is completed:

Unloading

  • Use the unloading system to remove finished parts
  • Avoid direct contact with hot materials

Shutdown Procedure

  • Turn off the laser source
  • Close assist gas valves
  • Power down the machine in the correct sequence
  • Clean residual scrap from the work area

Safety Tips for Laser Tube Cutting

  • Never place hands or body parts inside the protected cutting area
  • Press the emergency stop immediately in case of abnormal conditions
  • Do not modify parameters without proper training
  • Contact technical support if issues cannot be resolved
