The Jetair Indexer is the ideal machine for blast cleaning or treating components which are too fragile or too awkward to tumble. Parts are processed in such a way that they do not come into contact with any other parts or moving machinery. Components are loaded and unloaded to and from the machine usually by a pneumatic pick and place unit (available as an optional extra) situated at the front of the machine in easy reach of the entry and exit openings. The Indexer comprises a circular web carrying independently rotating heads (usually fitted with twelve) to which a jig or tool holder attaches. As each station indexes around the machine it rotates 360 degrees in front of a series of adjustable blast guns. The stations are individually designed to hold the components in exactly the right positions whilst they are being blasted to ensure that the correct coverage is achieved each time. The Jetair Indexer can be operated with a wide range of blast media.
