Renown finishing and shot peening equipment manufacturing experts Guyson International, have created a new universal automated blast system, based on its existing Multiblast® RSB, that now incorporates roof mounted servo drives to provide saturation coverage from the attached blast guns, across the entire rotating table; allowing full blast coverage to multiple components positioned on the table.

This new universal automated blast system will prove ideal for subcontractors or manufacturers with a varied component mix of geometric sizes and shapes with a requirement for a value adding cosmetic finish, shot peening, general deburring, paint removal, aerospace MRO cleaning or surface finishing.

With a standard blast chamber dimension of 1500 mm (wide) x 1500 mm (deep) x 900 mm (high), the cabinet is fitted with a large front opening door allowing easy parts loading access to a one metre 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 whilst retaining gun position, stand-off, angle etc. Automated post blasting air wash is also provided, as standard, to remove any blast media residues and leave the parts clean for any subsequent process.

For optimum component blast coverage, the machine can be provided with either horizontal or vertical servo driven gun drives. Both provide 500 mm of precise traversing travel, either across the turntable for full saturation coverage or vertically stroking (up and down) taller components to provide uniform coverage, whilst the part rotates on the turntable. Component shape and dimensions dictates were the individual guns are set for the correct angle and stand-off distance to achieve overall coverage of the target surfaces and these can be easily set via a full width, right hand side door, which is fitted for gun set up, adjustment and maintenance.

Guyson Multiblast® RSB - automated blast system

A complete Guyson RSB automated blast machine installation includes an efficient Guyson model C800 twin cartridge dust collector designed to draw off and collect the dust laden air from the blast cabinet. The heavier extracted particles are deflected downwards towards the collection bin, 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 the cartridge requires replacing. For applications where the dust represents a health hazard Guyson offer a HEPA grade 14 secondary filter. Typical dusts with health risks are nickel present in Inconel turbine blades and cobalt chrome present in old design orthopaedic implants.

All Guyson Multiblast machines are provided with a human machine interface (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 programmable logic controller (PLC). The panel can also display control settings, production data and system feedback such as sensor and fault indications or maintenance prompts.

This new universal Multiblast RSB blast system allows virtually unlimited scope for custom specification. The 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 substantial blast media savings, improve cabinet visibility, and help with a more consistent quality finish. These can be also coupled with enhanced blast media sieving and uprated dust collectors if the application warrants.

Prospective user of Guyson automated blast systems are encouraged to submit sample components for free feasibility testing to the company’s extensive development workshop located in Skipton, England.
