The following are the commonly
known different types of lathe machines:
(a) Speed Lathe. These lathes may be of bench type or they may have the
supporting legs cast and fitted to the bed. These lathes have most of the
attachments which the other type of lathes are having but have no provision for
power feed. They have no gear box, carriage and the lead screw. The tool is fed
and actuated by hand. Such lathes are usually employed for wood turning.
(b) Centre lathe. Centre lathe is a type of lathe in which the entire
change of spindle speed is accomplished by set of gears, which can be operated
by a lever to obtain required spindle speed.
(c) Gap Bed Lathe. In gap bed lathe, a section of the bed adjacent to
the headstock is removable. The gap bed may be removed whenever an extra larger
diameter work piece is required to be machined.
(d) Turret and Capstan Lathe. These lathes are development of the
engine lathe and are used for production work. In these machines the tailstock
of engine lathe is replaced by a hexagonal turret, on the face of which
multiple tools may be fitted and fed into the work in proper sequence. The
advantage is that several different types of operations can be done on a job
with minimum waste of time.
(e) Bench Lathe. Bench lathe is a small lathe, which can be mounted on
workbench for doing small light jobs.
