1. Purpose of filing

By filing chips are removed from straight or curved faces of pre-machined parts.

It serves to change the size, shape or surface finish of faces, to remove irregularities, to deburr, chamfer or round off edges, and to make parts fit.

Filing is hard and time-consuming manual work. It is useful only in single-piece production, repair work and partly in assembly work (fitting work and reworking).
