A cooling installation for a machine tool or the like, having a circulation system in which coolant circulates, wherein the coolant is conducted to a tempering device of the machine tool, wherein a metering unit is assigned to the circulation system, by which an external coolant can be metered to the coolant circulating in the circulation system, and wherein the metering unit can be controlled by a control device. In order to set the best possible constant temperature level at the tempering device, the circulation system has a buffer tank through which the coolant is conducted, and the metering unit meters the external coolant into the return flow coming from the tempering device and into the circulation system upstream of the buffer tank.
