Sandblasting, sometimes known as abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.
This began in 1935 when the idea of adding an abrasive to the water stream was developed by Elmo Smith for liquid abrasive blasting. [21] Smith’s design was further refined by Leslie Tirrell of the Hydroblast Corporation in 1937, resulting in a nozzle design that created a mix of high-pressure water and abrasive for the purpose of wet blasting.
Abrasive jet machining (AJM), also known as abrasive micro-blasting, pencil blasting and micro-abrasive blasting, [1] is an abrasive blasting machining process that uses abrasives propelled by a high velocity gas to erode material from the workpiece. Common uses include cutting heat-sensitive, brittle, thin, or hard materials.
Vacuum blasting is an abrasive blasting method, [1] also referred to as dustless blasting or closed loop abrasive blasting. [2] The method is characterized by a blast tool that does abrasive blasting and collects both used blast media, and loosened particles from the surface to be treated, simultaneously.

The pressurized water acting as a cutting jet can be re-used, with adequate filtering, creating a closed water circuit. [ citation needed ] However, the majority of users do not re-use the water. If more widely used, CryoJet may produce a drastic reduction in the amount of abrasive waste spill currently produced during the water jet cutting ...
