Abstract
There is provided a multi-turret lathe with two opposed spindles which is capable of machining a workpiece more effectively. The lathe with two opposed spindles includes: a first spindle (2); a second spindle (4) located opposite to the first spindle on the same axis and movable toward and away from the first spindle; and a set of two tool turrets (8a and 8c) which machines a workpiece cooperating with the first spindle, and another set of two tool turrets (8b and 8d) which machines a workpiece cooperating with the second spindle, and the two tool turrets in each of the sets are disposed opposite to each other about a spindle axis (B). Each of the four tool turrets is mounted on a tool slide which is movable and positionable in the direction of spindle axis and also in the direction perpendicular to the spindle axis. This enables each of the four tool turrets to be movable from a position to machine a workpiece held on one of the spindles and another position to machine a workpiece held on the other spindle.
