Technological Engineering! All Texas Airsonics’ systems include our patented Spirofeed™ powder delivery system, which delivers the most uniform, precise and controllable powder flow available. This technology allows for control of the abrasive flow from 0 to 50 (+/- 1) grams per minute, consistently and reliably, with the turn of a knob.
Abrasive Jet Machining, or AJM, is the impingement of fine abrasive particles in a high-velocity gas stream. This process is also referred to as “pencil blasting” or “micro-abrasive blasting”.
sandblasting?
AJM differs from conventional sandblasting in that the abrasive is much finer, the nozzles much smaller, and the process parameters are precisely controlled, thereby ensuring the utmost precision in cutting action. AJM can be used to process hard, brittle materials (germanium, silicon, mica, glass, ceramic, Nitinol, etc.) in a large variety of applications ranging from cutting to cleaning. The process is inherently free from chatter, vibration, and heat problems because the tool never touches the substrate.
