Main Features and Applications of Barrel Finishing

Barrel finishing needs to put workpieces, abrasive products and grinding agent into the roller according to certain mixing ratio. When the roller moves, it will produce strong extrusion force and flow force between workpieces and abrasive products, which will cause the collision, rolling force, etc., so as to achieve the barrel finishing for the surface of workpieces.

Barrel finishing has the following main features:

A, It has simple operation, high efficiency and less environmental pollution;

B, It can remove oxide layer and make surface cleaning of castings and forgings, and can be also used for deburring and refining surface, to reduce the surface roughness value;

C, It can improve the surface stress distribution status;

D, It is relatively difficult for internal holes, grooves and concave surface finishing, and needs for protection in the process of finishing.

At present, some aviation parts have not completely get rid of manual polishing method, which has to cost a lot of human resources, and is also easy to cause unstable product quality, and even affects the performance and service life of engines.

Barrel finishing technology can effectively improve the quality level of parts surface, remove burrs and other surface defects, and also can make metal parts surface produce weak plastic deformation, to improve surface residual stress. The application of barrel finishing technology in some aircraft engine parts manufacturingy, has achieved good economic and social benefits.
