Automated Rotary Head Abrasive Blast Systems For Complex Geometric Parts

In many applications, parts that require cleaning feature complex geometries, which can make thorough cleaning challenging. These intricate designs often include many angles and hard-to-reach areas where contaminants can accumulate.

A typical example of such an application is airfoil cleaning. Airfoils are generally fabricated as single pieces consisting of three to four vanes. The pitch of the blades and their close proximity to each other create difficulty in accessing all surfaces effectively.

Two main blast cleaning technologies used for these applications are linear oscillators and swing-arm oscillators. Linear oscillators deliver a single pass over the part, while swing-arm oscillators move in an arc, providing only one pass from a single angle.

In contrast, automated rotary head abrasive blast machines offer a significant advantage. These machines provide two passes under the blast guns—one on the leading edge and one on the trailing edge—effectively doubling the exposure time and angles covered. The rotary head’s 360-degree rotation ensures complete coverage, reaching all surfaces of the part.

Rotary heads are also effective for cleaning other complex parts, such as turbine blades, buckets, and vanes, all of which require multi-angle cleaning for thorough results.
