Guyson International has added the Multiblast RXS1400 automated blast system to its portfolio of rotating-indexing spindle solutions. Suited to the complete surface treatment of components that can be blast-finished or shot-peened while rotating about one axis, Guyson’s largest standard indexing system can handle components with a maximum component size of 400 mm high by 400 mm diameter, with weight up to 25 kg.

Notably, the blast system is suitable for medium to high volumes of: automotive transmissions; aerospace and land-based turbine components; railway, wind and construction equipment; and substrate materials in metal, composite or exotic alloys.

The Guyson Multiblast RXS1400 machine is a six-spindle rotating indexing blast system that can process multiple parts simultaneously; two blast stations make it extremely suitable for high volume manufacturing. Each of the six work spindles are spaced equally around the perimeter of the rotary indexing table and arranged so that at all times two of the spindles are outside the machine during the blasting operation for loading and unloading. Due to the rapid table indexing of the RXS1400, the load/unload environment is generally protected with a light-guard failsafe safety device.

Guyson’s sales manager Ian Rayner states: ″Customers can specify the RXS1400 as either suction-fed or pressure-fed, with the choice directed by application and throughput requirements.″

Parts are loaded on to the left-hand spindle and enter the blast chamber via pneumatic sliding doors. These open and close automatically and interface with the table indexing mechanism. Importantly, the doors also create a seal during the blast operation to prevent media and noise from escaping to the work environment.

A newly established manufacturing line for compression springs at a production facility of Baumann Springs takes place in a tumble-belt blast machine from Rösler. In short cycle times, the custom-engineered blasting solution produces surfaces that are optimally prepared for the subsequent coating operation. Furthermore, oil that carries into the shot-blast process is neutralised and, through the media cleaning system, separated from the blast media.

Located at the Stare Mesto, Czech Republic plant of Baumann Springs, the new production line accommodates different types of long compression springs made from EN 10270-2 spring steel. For cleaning and texturing (roughening) the surface of the springs prior to coating, the company uses a Rösler RMBC 4.2-HD tumble-belt blast machine.

“The Rösler solution impressed us not only because of its design, but its functionality,” explains Claudio Hertig, project manager global operations. “Another positive factor was the sturdy machine construction.”

Rösler’s RMBC 4.2-HD allows the blast cleaning of loosely tumbling compression springs with batch weights of up to 1,000 kg. Two Gamma 300G turbines, each equipped with a power of 11 kW, ensure high shot-blast intensity. These turbines, developed by Rösler, are equipped with curved throwing blades in a ‘Y’ design. Compared with conventional turbines, the specially calculated blade curvature generates very high media throwing speeds, resulting in up to 20% higher blast performance and, in turn, shorter cycle times.

Integrated blast media deflectors further intensify and accelerate the blast process. These special compressed air nozzles cause an additional blast-media movement. The automatic blast-media flow control allows not only the monitoring but also the precise adjustment of media flow to the respective workpieces. Media replenishment takes place automatically.
