Frequently Asked Questions
General Questions
What is a laser cutting machine?
A laser cutting machine uses a high-powered laser beam to cut or engrave materials like metal, plastic, or wood with precision.
What is the difference between laser cutting and laser welding?
Laser cutting is used to cut materials into desired shapes, while laser welding uses the laser to fuse materials together—typically joining metal parts with precision and minimal heat distortion.
What are the benefits of using laser cutting technology?
Laser cutting offers high precision, fast processing speeds, minimal material waste, and the capability to cut complex shapes with a clean finish.
Is laser cutting suitable for mass production?
Yes, laser cutting is ideal for both small and large production runs, offering high precision and speed with minimal material waste.
What is the cost of a laser cutting machine?
The cost varies depending on the power and features of the machine. Entry-level machines can start at a few thousand dollars, while high-end industrial machines can cost several hundred thousand dollars.
Capabilities and Specifications
What materials can a laser cutting machine cut?
Laser cutting machines can work with a wide range of materials including metals (like steel and aluminum), wood, acrylic, glass, fabrics, and more—depending on the laser type and power.
How thick of a material can a laser cutting machine cut?
The maximum thickness depends on the laser's power and the type of material. For example, a high-power CO2 laser can typically cut up to 20mm of steel or even more in some cases.
What is the cutting speed of a laser cutting machine?
Cutting speed varies based on material thickness, laser type, and power settings. Thinner metals may be cut at speeds of around 10 meters per minute, while thicker materials require slower speeds to maintain quality.
What is the precision level of laser cutting?
Laser cutting generally achieves high precision with tolerances as tight as ±0.1mm, making it ideal for intricate and detailed work.
