Laser cutting - Wikipedia
Laser cutting is a technology that uses a laser to slice materials. While typically used for industrial manufacturing appliions, it is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics.
Steel Composition and the Laser Cut Edge Quality - TWI
Laser users have four basic requirements for laser cutting: cut quality, cutting speed, cutting reproducibility and material cost. Currently, most of the evidence for factors that affect cutt ability is anecdotal, from end users and, more particularly, from steel suppliers who have launched ''laser …
Cutting metal with cutting wheels - The FABRIOR
Silicon carbide, on the other hand, is a very sharp grain but not quite as tough, making it suitable for cutting nonferrous metals. Zirconia alumina is a self-sharpening, tough, durable grain that holds up well in a range of demanding appliions.
Silicon carbide technology reaches tipping point
Silicon carbide will be the next good thing, but we have to find the appropriate entry points.” One particular entry point which Infineon has identified is the on board charger in EV and hybrid vehicles. Not only does SiC bring value to this, it also translates into But
