Guyson RXS200 - Micro Component Gritblaster

Press release April 28, 2010 Business

Guyson International introduces the highly compact Guyson RXS200, automated blast machine, engineered specifically for the precision micro component manufacturing environment.

Specialist industrial finishing equipment manufacturer Guyson International, has introduced a new addition to its range of automated rotary blast finishing systems. The highly compact Model RXS200 - Rotary Indexing Spindle blast machine is engineered specifically for the precision micro component manufacturing environment.

Guyson have developed this compact Multiblast system to perform a variety of blast applications, including shot peening, blast cleaning, deburring, cosmetic finishing and technical surface preparation on micro components such as dental screw implants and medical trauma screws and pins.

The blast cabinet is manufactured from high grade 316 L stainless steel and features two model 400 blast guns (as standard) also made from stainless steel along with all other ancillary internal parts. The whole system has been designed to be small enough to fit into the most compact manufacturing cell, yet capable of precise and repeatable impact treatment in single piece work flow manufacturing operations.

The Guyson RXS200 operates with two sealed and abrasion protected ball bearing spindles that index in and out of the blast chamber by means of a precision rotary actuator;  that enables robotic load and unload capabilities, if that is a customer requirement. The twin rotary spindle operation allows maximum efficiency of operation, with one component being loaded during the blast cycle of the other piece. Interchangeable component-holding fixtures can be quickly secured on each spindle allowing product changes to be made speedily and easily. A side door with a viewing window offers full access to the process chamber for inspection, adjustment and maintenance.

The fixtured component rotates at a controlled, adjustable speed and is exposed to blast media from multiple nozzles that are pre-positioned at the correct angles and distances for overall or selective coverage of the target surfaces. Blasting is achieved rapidly and thoroughly by multiple model 400 blast guns that are rigidly held in fixed position on multi-adjustable brackets. An automatic air wash is provided post blasting to remove any residual dust and blast media.

The Guyson RXS200 is provided with a touch-screen interface 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. Also included in the panel is a built in printer which delivers validation output on items such as blast settings, timings, customer batch references etc.

One of the numerous options offered with this advanced blast system includes a single or twin deck media sieve located underneath the cabinet, to maintain its small operational footprint, to separate contaminants and fines from the recirculated media and an efficient cartridge type dust collector that filters exhaust air to prevent discharge of particles into the work environment. Guyson offer several media delivery and reclaim system enhancements, including twin media hoppers and media vibrators to meet special fine media separation and dust control requirements.

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