Laser cutting machines are able to cut metal with great precision. This is the main reason they are so popular. Plasma cutters can be cut with 2X greater accuracy than laser cutting machines. Plasma lasers can be used to cut metals with a precision of 0.1mm, or.004 inches. Laser cutters can cut metals at a precision of.05mm to.002 inches.
Fiber lasers can also cut through reflective materials, provided they have enough power. With enough power, they can cut through almost any metal. Their cutting power will limit their ability to cut through thicker metals.
