Mechanical finishing finds many uses and involves cleaning, deburring and polishing parts especially metal ones. Tumbling barrels and vibratory machines are used for this function. Barrels are ordinarily horizontal and the vibrators are in the shape of tubs. It is possible to load the parts to be finished and the mass finishing media into these machines together. These are equipment which are moved in a number of specific ways to make the media and the parts to scour against each other thus causing an abrasive accomplishment which in turn cleans or polishes according to the condition. Sometimes, to ensure that re-depositing of the deburred parts does not occur, several chemical compounds are also added to the machines.

The equipment come in different models like those that can be mounted on to tables and those that are installed on the floor. Both dry and wet finishing can be done. In the tumbling barrels the abrasive materials are pushed or slid to reach the necessary finish. In vibratory tubs the media are moved about more tenderly. Hence while tumbling barrels are ideal for heavy deburring and cutting operations and for tiny components, while the vibratory tubs are used to carry out gentler finishing desires on superior manufactured parts. For some wants like cleaning, deflashing, stripping etching etc, blasting machines are also used with blasting media which range from super fine to super coarse, for tender to assertive requisites.

The media used can be ceramic, plastic, chemical or organic. Plastic media is preferred for gentle polishing and in cases where the parts involved are fragile. Plastic weighs much less when compared to ceramic; it is easier on the surroundings when compared to chemicals and it is a great deal more durable when weighed next to organic media. When the parts to be finished are made of soft metals like aluminum or delicate materials like fiberglass, the only method to accomplish optimum and damage-free results is by using media that are prepared out of plastic. This particular media finds very explicit usage in the airframe components/ structures maintenance.

Plastic polishing media are accepted for numerous finishing operations. Each condition needs the media to be made from a explicit kind of material and have a certain shape and size. To meet all requirements, these abrasive items come in diverse plastic types (each having a dissimilar density), an assortment of sizes like cones, cylinders, triangles, round, oval and so on. Sizes too vary from very minute to very large ones. The plastic media are usually available in bulk quantities. For some purposes a sole shape and size will be enough. For others various shapes and sizes have to be taken together for the duration of the finishing process. For instance in the case of a part that has a basic surface, plastic media in just one shape and size should suffice. But in the case of a component that has a surface with many dents, holes etc - each of which needs to be cleaned or polished - the tumbling-media has to essentially include a whole selection of shapes and sizes.
