Sandblast Equipment Terms –
Media used for blasting, grinding or polishing. Abrasive materials are
either in loose form or formed together into wheels, files or bricks or
adhered to cloth or paper with resin or glue. Natural abrasives include
sand, baking soda, garnet, emery, flint and corundrum. Metallic shot,
grit and plastic material are also used as abrasives in cleanings of castings
and surface preparation. – A continually flowing air line respirator fabricated to cover the shoulders, head and neck of the wearer. Its purpose is to protect the worker from recoiling abrasive. – Hard mineral formed from the chemical reaction between oxygen and aluminum; the creation of aluminum oxide on the surface of a metal prevents future occurrences of oxidation. – Procedure involving the use of abrasives such as coated or bonded abrasives to remove burrs, jagged edges or protuberances on the surface of an object created during industrial applications. – The amount of time that a blasting nozzle remains fixed upon a particular area. Extended dwell times may cause excessive heat generation and damage the product. – A naturally-occurring abrasive containing aluminum oxide and iron oxide used in light applications rather than industrial processes because of its low hardness. – The extent to which abrasive grains break or split apart upon impact or under pressure; friable abrasives fracture relatively easily and posses a shorter lifespan. – A rapid, dust free process that leaves the substrate clean and dry. Shot blast machines hurl shot toward the intended surface at a high speed, removing debris, paint and buildup from the surface. –
A blast machine procedure that prepares a part or surface to withstand
stress or fatigue breakdown. – Category of hard mineral abrasives consisting of diamond and CBN; superabrasives maintain tremendous hardness. – Tough, artificial abrasive used in heavy sandblasting applications involving various forms of steel.
