A Iathe assembly comprising:
a base unit having first and second longitudinal ends,
a headstock assembly provided adjacent said first Iongitudinal end of said
base unit, said headstock assembly including a spindle housing having a spindle
shaft extending therethrough,
a first Iathe bed assembly provided on said base unit and including a
bedway extending Iongitudinally in a direction parallel to said longitudinal axis of
said spindle for slidably receiving at Ieast one of a tool rest and a tailstock;
a second lathe bed assembly detachably coupled to at Ieast one of said first
and second Iongitudinal ends of said base unit, said second bed assembly
including a second bedway for selectively receiving at least one of a tailstock and
a tool rest assembly; and
an indexing assembly for angularly positioning and holding said spindle
shaft with respect to said spindle housing at any one of a plurality of intervals, said
indexing assembly including an indexing component fixedly secured to said
spindle shaft and an indexing pin mounted to said spindle housing of said
headstock assembly, and spring urged toward engagement with said indexing
