The spindle of the lathe has many attachments which facilitate turning, boring, facing, etc. The spindles have various configurations that you should be aware of.

The Threaded type spindle nose (figure 1) is the oldest type and has no taper to assist in mounting a chuck or attachment and is screwed on the spindle until the end bears on the spindle flange.

The tapered key type spindle (figure 2) is assisted by a taped nose, a key on the nose and secured with a threaded collar.

The cam-lock type spindle nose (figure 3) has a short taper that accurately positions the spindle mounting and has cam studs that fit into a ring of holes and cam-locked by turning a chuck key. This is the most common spindle nose found on lathes today.
