Lately, we’ve been doing a lot of talking about laser cutting. Fine laser cutting, that is. But what, exactly, is ‘fine’ laser cutting? Fine laser cutting applies to the cutting of metals, such as 300 and 400 series stainless steel, aluminum, nickel, titanium, nitinol and copper less than 0.04” (1.0mm) thick. In fact, they can be very thin - 0.0005”-0.002” (10-50 microns) - as the laser imparts no physical force on the part during the process. In addition to the thickness of the part, fine cutting is also defined by cut feature tolerances which can be down to ± 0.0005”.
