Fiber laser cutting tolerance. Laser cutting is a technology that uses a laser to cut materials and is typically used for industrial manufacturing applications but is also starting to be used by schools small businesses and hobbyists. Laser cutting tolerance there are several factors that play into part accuracy. This focused laser beam meets the sheet metal and melts it. At jacks machine company we leverage the power of our 2kw fiber laser to produce precision parts in prototype to high volume quantities. He said he can hold tighter tolerances if asked but cutting would be slower and thus more expensive. One example is the use of laser cutting equipment to produce high tolerance holes in a speedy manner instead of taking metal blanks to a secondary station for additional holemaking activities. The two most common types of laser cutting machines are fiber laser and co 2. Our laser is a 3 kw trumpf trudisk. You must slow down around features to maintain the desired accuracy. The actual accuracy also depends on how you program the laser. Figure 1 accrotools new nx f fiber laser cutting machine is producing higher quality parts than the old 1500 w machine it replaced. The laser beam is created by the laser source resonator conducted by mirrors or a transport fiber in the machine cutting head where a lens focuses it at very high power on a very small diameter. This is not part accuracy though. Laser cutting works by directing the output of a high power laser most commonly through optics. My laser cutting vendor routinely holds 015mm 0005 tolerances with no problem in steel up to 10mm 0375.

First is the accuracy of the laser. Laser cutting is a thermal cutting process for processing sheet metal. Fiber lasers vs co 2. The laser optics and cnc computer numerical control are used to direct the material or the. As a result they are always looking to maximize the capabilities of their equipment. Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting. Kerf compensation is performed automatically by the laser so if you ordered a large part in thin material you could expect the part width and height to be accurate to within roughly 001 across a full 10 span worst case. Our fiber laser has a head positioning tolerance of 0005 across the entire 5 x 10 deck. Some lasers have a position accuracy of 001. Fabricators want to process metal parts with the least amount of handling as possible. Co 2 lasers use an electromagnetically stimulated gastypically a mixture. With its high speed laser head energy efficiency and versatility our fiber laser is adaptable to a wide variety of cutting applications. In this article we describe edge quality and cut tolerances for steel laser cut parts from 18 to 34 thick a36 steel generic low carbon mild steel in general the edge quality on laser cut steel parts depends on laser power assist gas and laser type ie.
