Abstract

A machine tool (100) has a spindle (101) and a turret or toolholder (124) which are disposed at the front of a base (134).A workpiece (W) is rotated by the spindle (101). The turret (124) is movable toward and away from the workpiece (W) along a path which has vertical and horizontal components. A conveyor assembly (200) is operable to move workpieces between the rear of the base (134) and the spindle (101) along a path (A) which extends through a plane (E) which contains the axis (C) of rotation of the spindle. The plane (E) is parallel to vertical and horizontal components of movement of the turret (123). An alternative embodiment (100a) of the machine tool includes a pair of spindles (101a, 301) and a pair of turrets (124a, 324) disposed at the front of a base (134a, 334). Workpieces (W9, W10) are moved two at a time between the rear of the base (134a, 334 ) and the two spindles (101a, 301) along a path which extends through a plane which contains the axes (C, J) of rotation of the spindles (101a, 301). A pair of chip conveyors (129a, 329) transport chips in opposite directions from the spindles (101a, 301).
