GEARBOX
The gearbox is located on the left side of
the lathe and is mounted on the bed. It is
used to select the feeds for straight
turning
as well as for thread cutting. In order to
achieve certain thread pitches, it is
necessary to replace the change gears.
The torque of the work spindle is
transmitted to the feed gears and thus
to the lead screw.
