More accurate and cost effective comparing with machining, manual punching, and casting
Laser cutting technology uses a concentrated beam to cut materials, and is typically used for industrial manufacturing applications. Material melts, burns, vaporizes, and is blown away by a jet of gas (typically nitrogen or oxygen), leaving an edge with a high-quality surface finish.
Advantages of laser cutting over mechanical cutting include easier work holding and reduced contamination of work piece, since there is no cutting edge which can become contaminated by the material or contaminate the material.
The high degree of precision and limited material take away, allow the components being processed to be nested to as close as 0.125” spacing. When processing stainless steel to high alloy, this material savings could significantly reduce input material costs based on less materials being required.
In many cases the savings off-sets labour costs vs. traditional methods such as plasma/flame cutting.
Precision is highly consistent (standard cut tolerances of +/-0.008″), since the laser beam does not wear during the process. There is also a reduced chance of warping the material that is being cut, as laser systems have a small heat-affected zone. Some materials are also very difficult or impossible to cut by more traditional means.
Due to higher speed, laser cutting is more accurate and more cost effective, comparing with machining, manual punching, and casting.
