ABSTRACT:
There is provided a high-production machining device having first and second spindles rotatably mounted on a headstock. A carriage is slidably mounted on the machine bed, and in a preferred embodiment a first drive assembly is provided for sliding the carriage across the upper face of the bed along a transverse axis thereof. First and second slides are slidably mounted on the carriage for movement in a direction normal to the transverse axis, with the first and second slides each adapted to carry a machine tool and each being attached to a common second drive assembly for moving the slides in that normal direction. A linear sensor monitors the positions of the first and second slides relative one another, and an independent compensating assembly is provided for adjusting the position of one of the slides relative the other in the normal direction, whereby positions of the first and second slides in the normal direction can be effectively independently controlled. In a preferred embodiment, the machining device further includes an independent adjustment device for moving one of the spindles relative the other in a direction parallel to the transverse axis, whereby the positions of the first and second slides in the transverse direction can be effectively independently controlled.
