Size and specification of lathe

Size of lathe is usually specified by :-

• height of the center measured from the lathe bed.

• swing of a work piece diameter over bed. this is the maximum diameter of work that can be rotated on a lathe

• maximum distance between the center; maximum length of a work piece that can be mounted between the lathe center

• the length of a bed; indicated the approximate floor space occupied by a lathe

For example, if a lathe size indicated by 400mm * 864mm * 1900mm means maximum diameter of a work piece is 400mm, 864mm is the length between the lather center and 1900 mm is the length of the lathe bed.
