What is The Depth of a Laser Marking Machine

The depth of laser marking depends on several factors, including the type of laser, material being marked, laser power, marking speed, and focus settings. Here’s a general overview:

Typical Laser Marking Depths:

1. Fiber & CO₂ Lasers (Surface Marking):

• Usually creates very shallow marks (a few micrometers to 0.1 mm).

• Best for engraving logos, serial numbers, or barcodes without deep penetration.

• 
  

2. Deep Engraving Lasers (Fiber/CO₂ with Higher Power):

• Can achieve 0.1 mm to 1 mm depth with multiple passes.

• Used for industrial part marking, molds, or tools.

• 
  

3. Ultra-Deep Engraving (Specialized Lasers):

• Some high-power lasers (e.g., pulsed fiber or Nd:YAG) can engrave 1 mm to several mm deep but require multiple passes.

• Used for metal stamps, deep engraving on steel, or hardened materials.

• 
  

Factors Affecting Depth:

• Laser Power (Higher power = deeper marks)

• Marking Speed (Slower speed = deeper engraving)

• Material Type (Metals require more power than plastics or wood)

• Focal Length & Lens (Tighter focus = finer but shallower marks)

• Number of Passes (More passes = deeper engraving)
