Band Filing

Band Filing

Band Filing --A band filing machine resembles a vertical band saw with the difference that instead of the conventional band saw blade this machine employs a file band and is used for filing work.

-The file band is made up of files mounted on a flexible Swedish steel band.

-A light to medium pressure is used and the filing speed ranges from 15 to 60 m/min.

-The filing operation is accomplished with a continuous downward stroke. The absence of a backstroke greatly lengthens the life of the file and helps in holding the work on to the table.

-Files used in the file band may be:

(i) Single cut, double cut and rasp cut. Rasp cut differs from the other two in that the teeth are disconnected from each other each tooth being made by a single punch.

(ii) Rough, coarse, bastard, double cut and smooth.

(iii) Flat, oval, half round and mill.
