Mini-lathes and micro-lathes are miniature versions of a general-purpose center lathe (engine lathe). They typically only handle work of 3 to 7 in (76 to 178 mm) diameter (in other words, 1.5 to 3.5 in (38 to 89 mm) radius). They are small and affordable lathes for the home workshop or MRO shop.
Lathes have four main components: the bed, the headstock, the carriage, and the tailstock. The bed is a precise & very strong base which all of the other components rest upon for alignment. The headstock's spindle secures the workpiece with a chuck , whose jaws (usually three or four) are tightened around the piece.
