Beginner’s Guide To Adjusting A Laser Cutting Machine: Remember These 7 Parameters

Are you new to laser cutting? Don’t panic! While many settings can be left alone, these 7 core parameters are critical for quality, speed, and cost. Wrong settings can ruin your material.

1. Speed: Controls Cutting Speed

• Too fast: Won’t cut through, rough edges.

• Too slow: Burns material, low efficiency.

• Small holes or curves: Reduce speed to prevent overburn.

2. Height: Controls Stability

• Closer: More stable but risk of collision.

• Farther: Safer but less stable.

• Thick plates: Raise focal height to avoid lens contamination.

3. Gas: Controls Cutting Effect

• Air: Best for thin plates, low cost.

• Oxygen: Best for thick plates, aids combustion.

• Nitrogen: Best for stainless steel, prevents oxidation.

• Wrong gas: Can ruin the plate immediately.

4. Air Pressure: Controls Slag Removal

• Higher pressure: Cleaner slag removal, smoother cut.

• Thick plates: Need higher pressure for efficient slag removal.

5. Power: Controls Cutting Depth

• Thick plates: Increase power for deeper penetration.

• Thin plates: Reduce power to prevent burn-through.

• Idle moves (air cutting): Lower power to save energy.

6. Idle Power: Controls Precision

• Higher energy: Deeper cuts but rougher edges.

• Lower energy: Finer cuts, ideal for thin plates or small parts.

7. Frequency: Controls Line Width

• High frequency: Best for thin plates, narrower kerf.

• Low frequency: Best for thick plates, wider kerf.

• 5000 Hz: 5000 pulses per second, balancing speed and quality.

Remember: Don’t turn knobs randomly! Focus on these 7 parameters first, then fine-tune. Your cuts will improve instantly.
