A turret-lathe coolant system is disclosed for selectively directing a stream of coolant to an interface between a workpiece on a turret lathe and a cutting tool positioned by a turret to cut the workpiece. In the preferred embodiment, the system includes a coolant-discharge assembly secured to the turret, wherein the assembly has a plurality of semi-rigid coolant tubes that are affixed to coolant-distribution ports, to distribute coolant fluid to a plurality of cutting tools on the turret. A coolant plunger is affixed within the coolant-discharge assembly that includes coolant-discharge outlets that pass coolant fluid from within an interior chamber in the plunger through adjacent distribution ports in the assembly. A compound, four-bar linkage mechanism is pivotally secured to the coolant plunger and the lathe, to maintain the discharge outlets in the plunger in a fixed position relative to a rotational axis of the turret as the turret rotates and moves longitudinally and transversely along a bed of the lathe. The discharge outlets are positioned in alignment with the cutting tool positioned to cut the workpiece. Therefore, coolant fluid directed into the coolant plunger only passes out of the distribution tube adjacent the cutting tool positioned to cut the workpiece.
