Filing (metalworking)

Filing is a mostly manual, rare machine manufacturing process to form a workpiece by machining a small extent. Files is one of the cutting separation process with defined cutting edges. Use a file to nearly all metals, wood and plastics are machined by machining, but also horny body parts such as nails and hooves, the file is created.

Colloquially, the term is also used to express that to an object (also on a human) final improvements are carried out.

Method

The cutting motion and the advancing movement can be carried out by hand. The work, however, is firmly clamped, mostly between the jaws of a vice. In the past there were also machines filing, the predominantly found in tool use, but were now replaced by faster and more accurate machine tools.

On the type of file used A distinction roughing and finishing. Schruppfeilen usually wear a cross cut and serve the removal of larger amounts of material. The so -filed surfaces have deep scoring. Plain files are much finer toothed; often the spaces between the Zähnreihen be filled with chalk to prevent the scoring. The finishing operation is a precision machining and achieved cried poor surfaces, but regular brushing out of adhering to the file blade chips is required.

Files can be an exhausting, but at the same time very educational activity. It is one of the first exercises budding apprentice at tool mechanics, industrial mechanics, metal workers, gunsmiths, mechanical, technical draftsmen, metal cutting, automation core and most recently in the electronics engineers. However, the proportion of training time that is spent with files going steadily. While a mechanic nor any feilte in the 1970s in the first six months, exerts a trainee this activity today sometimes only two weeks out.
