Drag finishing machine
USF Surface Preparation Group
The components to be finished are attached to special fixtures and "dragged" in a planetary movement through a bed of mass finishing media. The process provides up to 40 times higher grinding performance when compared to typical vibratory finishing processes. The components are individually attached onto fixtures and therefore cannot impinge each other.
Parts well suited for drag finishing include:
High value or delicate components
Parts with many contours and complex geometries
Extremely hard materials that are difficult to machine
Examples could include: surgical implants, turbine blades, precision parts, pump & compressor components, parts made of hard metal (i.e. sintered parts, etc...)
The applications for drag finishing range from aggressive grinding and radiusing all the way to surface smoothing and high gloss polishing of decorative parts.
