FAQ about Laser Cutting

What is laser cutting?

Laser cutting is a process where a laser beam is used to cut materials. The laser beam is a concentrated beam of light that can be used to melt, vaporize, or oxidize materials.

What materials can be laser cut?

Laser cutting can be used on a wide variety of materials, including metals, plastics, wood, and fabric. However, some materials are more difficult to laser cut than others.

How does laser cutting work?

Laser cutting works by focusing a laser beam onto a material. The laser beam melts, vaporizes, or oxidizes the material, creating a cut. The cut can be either straight or curved, depending on the path of the laser beam.

What are the advantages of laser cutting?

Laser cutting offers several advantages over other cutting methods, including:

• High precision
• Fast cutting speeds
• Clean cuts
• Minimal burring
• Can be used on a wide variety of materials

What are the disadvantages of laser cutting?

Laser cutting also has some disadvantages, including:

• High cost
• Can only cut thin materials
• Can create fumes and dust

What is the difference between laser cutting and plasma cutting?

Laser cutting and plasma cutting are both thermal cutting processes, but they use different technologies. Laser cutting uses a laser beam to cut materials, while plasma cutting uses a plasma arc. Plasma cutting is generally faster and less expensive than laser cutting, but it can create more burrs and fumes.

What is the difference between laser cutting and waterjet cutting?

Laser cutting and waterjet cutting are both precision cutting processes, but they use different technologies. Laser cutting uses a laser beam to cut materials, while waterjet cutting uses a high-pressure stream of water. Waterjet cutting is generally less expensive than laser cutting, but it can be slower and less precise.

What are some applications of laser cutting?

Laser cutting has a wide range of applications, including:

• Automotive manufacturing
• Aerospace manufacturing
