Steel rougness
Wednesday, March 9th, 2011Surface roughness (or just roughness) (Ra unit) is a feature of solid (object, steel) surface. It is measured by optical or mechanical examination of flatness divergence which don’t reflect it geometrical shape. Rougness measure count on about scale at least one order of magnitude smaller than standard measure unit. We differentiate rougness from waviness of [...]
Steel Cutting by Fiber Laser
Thursday, December 2nd, 2010Let’s take a quick glance on a high power fiber laser during work (not gas lasers). Complex and smooth shapes like this fancy butterfly are cutted in 2mm stainless steel like picture printet od sheet of paper. Extreme precision conjuncts here with fast velocity of cutting and decides on quality of final product and new [...]
