The Guyson universal automated blast system is aimed at subcontractors or manufacturers processing a varied component mix of geometric sizes and shapes with a requirement for cosmetic finishing, shot peening, general deburring, paint removal or aerospace MRO cleaning.
With a standard blast chamber dimension of 1,500 mm (wide) by 1,500 mm (deep) by 900 mm (high), the cabinet is fitted with a large front-opening door, allowing easy parts-loading access to a 1 m wide, painted steel turntable (polyurethane version available).
As standard, the Multiblast RSB comes with two Guyson model 900 guns, each with its own individual pressure regulator, allowing optimum blast coverage of components on the table. This number can be increased to a maximum of eight guns if the blast application necessitates. A blast nozzle holding clamp option enables the guns to be swapped out for cleaning, while retaining gun position, stand-off distance and angle. Automated post-blasting air wash is also provided, as standard, to remove any blast media residues and leave the parts clean for any subsequent processing.
For optimum component blast coverage, the machine can be provided with either horizontal or vertical servo-driven gun drives. Both offer 500 mm of traverse, either across the turntable for full saturation coverage or vertically stroking (up and down) taller components to provide uniform coverage as the part rotates on the turntable. Component shape and dimensions dictate where the individual guns are set for the correct angle and stand-off distance to achieve overall coverage of the target surfaces. These parameters can be set easily via a full width, right-hand side door, which is fitted for gun set-up, adjustment and maintenance.
A complete Guyson RSB automated blast machine installation includes a Guyson model C800 twin-cartridge dust collector, which is designed to draw off and collect the dust laden air from the cabinet. The heavier extracted particles are deflected downwards towards the collection bin, while the lighter particles are captured on the surface of the filters. A magnehelic differential pressure gauge is supplied to monitor the filter cartridge and indicate when it requires replacing. For applications where the dust represents a health hazard, Guyson offers a HEPA grade 14 secondary filter. Typical dusts with health risks are nickel present in Inconel turbine blades and cobalt chrome found in older orthopaedic implants.
All Guyson Multiblast machines are provided with a HMI that simplifies operation of the automated blasting, streamlines access to control functions, and enables password-protected direct entry of dimensional data or processing parameters into the system's PLC. The panel can also display control settings, production data and system feedback, such as sensor and fault indications or maintenance prompts.
The automated Multiblast RSB blast system is offered in either suction or pressure-feed options, with either a turntable or single spindle for components. Various cyclone reclamators options are available, all of which provide blast media savings, improve cabinet visibility and help with a more consistent quality finish. These reclamators can be also coupled with enhanced blast media sieving and uprated dust collectors if the application warrants.
