Automotive crown wheels blast-etched
A system has been installed by manufacturers of powertrain technology to accurately blast etch two sizes of case hardened automotive crown wheel components that have been phosphated.
A short time ago a Guyson Multiblast RSX 900 blast system was installed by one of the world's leading manufacturers of powertrain technology to accurately blast etch two sizes of case hardened automotive crown wheel components that have been phosphated The original installation was planned to be manually loaded and unloaded and after an initial proving period, has now successfully progressed to a totally automated cell; being robot loaded and unloaded

Keying surface produced for anodising
When Bodycote a world leader in metal technology, were faced with a demanding finishing problem, coupled with an extremely tight delivery deadline, they approached Guyson International for help.
The Guyson RXS900 blast cabinet is fitted with an indexing rotating turntable that has six evenly spaced revolving work spindles which index through the process area presenting the components accurately and for a precise amount of time in front of the blast guns.
Blasting takes place at two of the six spindles, which are positively driven by a toothed belt to ensure an even blast coverage during rotation of the component.
The machine is equipped with (although not all guns are used all of the time) three model 900 and three model 400 blast guns mounted on fully adjustable arms.
The components are loaded onto the first spindle after the vertically sliding pneumatic door moves up out of the way.
The turntable then indexes twice round to the first blast station where a model 900 gun lightly blasts the internal bore of the component at a low blast pressure to remove light oxidation from the product with a glass bead blast media.
The turntable then moves further round to the next blast station where a pneumatically operated rotating bore mask comes down and seals off the internal bore to prevent it from being over-blasted whilst allowing the flat top of the gear to be blasted with two model 400 guns to remove a further ring of oxidation.
The component then indexes around into an air-wash compartment to remove any residue blast media and finally back to the unload position.
The system is completed with a model CY600-16 Cyclone Reclamator, connected to the cabinet with rigid polyurethane ducting and a GC20-K5 reverse jet pulse cleaning dust collection unit, supplied with secondary filter and pressure differential control on secondary filter.
The dust collection bin incorporates a wheeled waste media unit designed for ease of moving and lifting with a fork lift. Request a free brochure from Guyson International ...
