Blasting processes for surface finishing vary according to the size, quantity, composition, and desired finish of the work pieces in need of surface preparation. Air blasting and turbine blasting are two of the more common types of blasting. While there is some overlap between the two methods, each carries its own unique attributes and drawbacks.
When comparing these two blast methods, the number one thing to keep in mind is precision versus bulk. Air blasting provides precision surface preparation using a much smaller blast pattern compared to turbine blasting, which delivers large quantities of media over a wide blast pattern, thereby making it ideal for blasting large quantities of parts or larger individual parts.
