Extra-Large Blast Machine for Blast Etching Aerospace Rings

SKIPTON, U.K. - April 18, 2023 - PRLog -- Guyson International, the UK's foremost industrial finishing equipment manufacturer, has installed a Guyson Euroblast® 2-metre PF (Pressure Fed) blast system into a division of a leading European aerospace company. The extra-large blast cabinet is used to deliver a uniform etched key surface on a range of machined circular aluminium rings prior to bonding.

After blast trails performed at the company's Skipton demonstration centre, a Euroblast 2-metre PF blast system (2.1 m deep x 2.5 m wide internal cabinet) was specially designed by their engineering team to provide a side loading and forward tilting turntable which can accommodate rings up to 1.8 m diameter and a 20 kg load. The side loading scissor lift design permits the load table rails to be lowered, once the tilting turntable has been manually pushed into the blast chamber, allowing the full height cabinet side door to be tightly closed creating a seal to prevent dust and media escaping during the blast operation.

The external frame also allows components to be loaded outside the cabinet using a crane or hoist where necessary and is fitted with blast media catch trays and hopper to contain and collect any spent media, for a cleaner and safer working environment.

Blast etching of the aluminium rings takes place within the blast chamber, with the tilting turntable allowing the components to be vertically raised directly in front of the operator's eye line. This enables enhanced parts visibility, easier manual rotation of the turntable and better line-of-sight blast access to the rings.

A 55-litre capacity pressure pot is used to generate the blast stream within the blast chamber and when the full-width foot pedal (which can be operated by either foot) is depressed it pressurises the pot and starts the blast operation; similarly releasing the pedal de-pressurises the pot and stops the process.

Blast media is fed from the pressure vessel into the cabinet through a heavy-duty hose to the boron carbide blast nozzle. The flow of media is controlled by a manual pinch valve mounted on the cone of the pressure pot; this regulates the volume of media being released into the compressed air stream. After blasting a trigger operated air wash gun removes residual dust and blast media from the rings.

The whole blast system is completed with a Guyson C800 twin cartridge filter dust collector, a highly efficient unit for filtering out and collecting the dust-laden air from the blast cabinet.
