Common FAQs About Laser Engraving & Cutting Machines

Laser engraving and cutting machines are widely used in advertising, woodworking, signage, packaging, textiles, and industrial manufacturing. However, many buyers and first-time users still have questions before purchasing or operating a laser machine.
In this article, we answer the most common questions to help you choose the right laser engraving and cutting solution.

1. What Materials Can a Laser Engraving & Cutting Machine Process?

Laser machines can process a wide range of materials, depending on the laser type and power.

Common materials include:

• Wood, MDF, plywood

• Acrylic, plastic

• Leather, fabric, felt

• Paper, cardboard

• Rubber

• Coated metals and anodized aluminum (engraving)

⚠️ Bare metal cutting usually requires fiber laser systems, while CO₂ lasers are ideal for non-metal materials.

2. What Is the Difference Between Laser Engraving and Laser Cutting?

• Laser engraving removes surface material to create marks, patterns, or text.

• Laser cutting uses higher power to fully cut through the material.

One machine can usually perform both functions by adjusting power, speed, and focus.

3. How Thick Can a Laser Cutter Cut?

Cutting thickness depends on:

• Laser power

• Material type

• Cutting speed and settings

Typical examples:

• 80–100W CO₂ laser: 6–10 mm wood or acrylic

• 150–300W CO₂ laser: up to 20 mm wood

• Fiber laser: thin metal sheets (steel, aluminum, brass)

4. Why Are My Cutting Edges Burnt or Not Smooth?

This is one of the most searched laser cutting problems.

Common causes:

• Incorrect speed or power settings

• Poor air assist

• Dirty lens or mirrors

• Low-quality material

Solutions:

• Increase cutting speed

• Adjust power output

• Improve air assist airflow

• Clean optical components regularly

5. Is a Laser Engraving Machine Difficult to Operate?

Not at all. Modern laser machines come with:

• User-friendly software

• Auto-focus systems

• Preset material parameters

Most operators can learn basic operation within 1–2 days.

6. What Maintenance Does a Laser Machine Require?

Routine maintenance is simple and low-cost:

• Clean lenses and mirrors

• Check water chiller and cooling system

• Inspect belts and rails

• Keep the machine clean and dust-free

Proper maintenance significantly extends machine lifespan.

7. Is Laser Cutting Safe?

Yes, when used correctly.

Laser machines are equipped with:

• Emergency stop buttons

• Protective covers

• Warning indicators

Operators should follow safety guidelines and use proper ventilation systems.

8. How Do I Choose the Right Laser Engraving & Cutting Machine?

Consider the following factors:

• Materials you process

• Maximum cutting thickness

• Working area size

• Production volume

• Budget
