Lathe Filing
When filing work revolving in a lathe,
the file should not be held rigid or
stationary, but stroked constantly. A
slight gliding or lateral motion assists
the file to clear itself and eliminate
ridges and grooves.
While a Mill File is capable of good
lathe filing, there is a special long angle lathe file with teeth cut
at a much larger angle. This provides a cleaner shearing, self-
clearing file, eliminates drag or tear, overcomes chatter and
reduces clogging. Uncut edges on this file protect any shoulders
on the work, which are not filed, and the dog, which holds the
workpiece.
Lathe filing is usually employed for fitting shafts. Where stock is
to be removed, a 12"/300mm or 14"/350mm long angle Lathe File
is preferable. This file will provide the finish suitable for a drive
fit. For a running fit a Mill File will provide a smooth finish. Where
a fine finish is required a Swiss Pattern and or Pillar file in No. 4
should be used.
Recommended Surface Feet Per Minute For Lathe Filing
Many Lathe Filers make a practice of not using a new file for work
requiring an extremely fine finish.
In using the long angle Lathe File,
care should be taken at shaft ends
as this fast cutting file may cut
too deeply. Don’t run a hand over
lathe work, as oil and moisture can coat the surface and make
it difficult for the file to take hold. For lathe work that has oval,
eliptical or irregularly round form, the finer swiss pattern files are
most satisfactory.
