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). |

DETAILED DESCRIPTION OF THE INVENTION FIG.
1 is a pictorial illustration depicting the relationship between a machine tool and a workpiece conveyor assembly; FIG.
2 is a schematic illustration of the machine tool of FIG.
1 with the housing removed and illustrating the relationship between paths along which a workpiece is moved between the rear of the machine and a spindle disposed at the front of the machine; FIG.
3 is an exploded, somewhat schematicized illustration, depicting the construction and relationship between various parts of the machine tool of FIGS.
1 and 2; FIG.
4 is a sectional view, taken generally along the line 4--4 of FIG.
1, illustrating the relationship between a toolholder or turret and a spindle of the machine tool; FIG.
5 is a sectional view, taken generally along the line 5--5 of FIG.
4, further illustrating the relationship between the toolholder or turret and the spindle; FIGS.
6, 7, 8, 9 and 10 schematically illustrate the manner in which an alternative embodiment of the conveyor assembly is used to move workpieces to and from the spindle; FIG.
11 is a pictorial illustration of an alternative embodiment of the machine tool in which a pair of spindles and a pair of toolholders or turrets are disposed at front of a base of the machine tool; FIG.
12 is an exploded schematicized illustration, generally similar to FIG.
3, illustrating the construction of a portion of the machine tool of FIG.
11; and FIGS.
13, 14, 16 and 17 illustrate the manner in which a conveyor assembly is used to move workpieces to and from the spindles of the machine tool of FIG.
11.
Referring now to the drawings, FIG.
1 illustrates a machine tool 100 which is operable to perform machining operations on workpieces W.
A workpiece conveyor or transfer assembly 200 transports unfinished workpieces W to a spindle or chuck 101 in the machine tool 100.
The workpiece conveyor assembly 200 transports an unfinished workpiece W from the rear of the machine tool 100 to the spindle 101.
The conveyor assembly 200 also transports finished workpieces from the spindle 101 back to the rear of the machine tool 100
