GUYSON's twin spindle RSSA-6 pressure-blast system is designed with two vertically traversing nozzles for surface preparation of the inside diameters of two hollow cylindrical components per cycle. The nozzles can be reconfigured for blasting the O.D. of the parts, which rotate at controlled and adjustable speed as the motion of the media delivery nozzles is synchronized to yield even coverage of target surfaces.www.guyson.com
