The coolant nozzle carrier comprises at least two coolant nozzles and at least a center leg and two side legs that are attached to the center leg. Each of the side legs supports at least one nozzle and extends in a plane that is perpendicular to the rotational axis. The side legs are configured to accommodate the grinding disc in between the side legs with a moving gap defined between the grinding disc and the side legs. ## Claims ### Claim 1 A coolant nozzle carrier configured to be mounted to a grinding machine, the grinding machine having a grinding spindle defining a rotational axis, the grinding spindle being configured to support and drive a grinding disc, the coolant nozzle carrier comprising: at least two coolant nozzles configured to provide a fluid coolant to the grinding disk; at least a center leg and two side legs each being attached to the center leg, wherein each of the two side legs supports at least one of the at least two coolant nozzles, the two side legs extend in a plane and embrace a space dimensioned to receive the grinding disc; and at least one of a pivotable attachment and hinges, wherein at least one of the following conditions is satisfied: a) the side legs are pivotably attached to the center leg with said pivotable attachment, and b) each of the side legs comprises a corresponding hinge and a corresponding free end, said hinge enabling said free end of the side legs to pivot outward; wherein the at least one of the pivotable attachment and hinges are configured to provide a stop to define a minimum distance between the two side legs; and wherein the two side legs are spring loaded against the stop. ### Claim 2 (depends on 1) The coolant nozzle carrier of claim 1, wherein the center leg comprises at least one coolant inlet, wherein each of the side legs and the center leg comprises an internal coolant channel providing a fluid communication between the at least one coolant nozzle and the at least one coolant inlet. ### Claim 3 (depends on 1) The coolant nozzle carrier of claim 1, wherein the center leg is supported by a support bar, wherein the support bar extends perpendicularly to the center leg. ### Claim 4 (depends on 3) The coolant nozzle carrier of claim 3, wherein at least one of the support bar and the center leg comprises a locking member configured to release a connection between the support bar and the center leg. ### Claim 5 (depends on 3) The coolant nozzle carrier of claim 3, wherein the center leg contains a coolant channel, and wherein the support bar includes a coolant conduit configured to be in fluid communication with the coolant channel of the center leg. ### Claim 6 (depends on 2) The coolant nozzle carrier of claim 2, wherein the at least one coolant inlet of the center leg is connected to a coolant conduit-configured to supply a coolant to the coolant inlet, and wherein the coolant conduit has a longitudinal axis extending orthogonally to the center leg. ### Claim 7 (depends on 6) The coolant nozzle carrier of claim 6, wherein the coolant conduit and the coolant inlet of the center leg form a releasable coupling structured to couple and decouple the coolant conduit and said coolant inlet. ### Claim 8 (depends on 1) The coolant nozzle carrier of claim 1, wherein the center leg is rotatably supported, and wherein an axis of rotation of the center leg is said rotational axis. ### Claim 9 (depends on 1) The coolant nozzle carrier of claim 1, further comprising at least one nozzle having a coolant outlet configured to deliver a coolant flow tangentially with respect to a peripheral surface of the grinding disc and against a direction of rotation of the grinding disc. ### Claim 10 (depends on 1) The coolant nozzle carrier of claim 1, further comprising at least one nozzle having a coolant outlet configured to deliver a coolant flow tangentially with respect to a peripheral surface of the grinding disc and along a direction of rotation of the grinding disc. ### Claim 11 (depends on 1) The coolant nozzle carrier of claim 1, further comprising at least one nozzle having a coolant outlet pointing towards a front side or a rear side of the grinding disc. ### Claim 12 (depends on 1) A grinding machine having a grinding spindle configured to support and drive a grinding disc that has a rotational axis, wherein the grinding machine further comprises the coolant nozzle carrier of claim 1. ### Claim 13 (depends on 1, 12) The grinding machine of claim 12, further comprising: a first coolant nozzle carrier of claim 1, wherein the two side legs are dimensioned to embrace a space defining a first diameter, a second coolant nozzle carrier of claim 1, wherein the two side legs are dimensioned to embrace a space defining a second diameter, a coolant nozzle exchange apparatus configured, in operation, to transport and replace the first coolant nozzle carrier with the second coolant nozzle carrier and vice versa. ### Claim 14 (depends on 12) The grinding machine of claim 12, wherein the plane is perpendicular to the rotational axis, and wherein the two side legs are configured to accommodate the grinding disk in said space with a moving gap between the grinding disk and the two side legs. ### Claim 15 (depends on 12) The grinding machine of claim 12, wherein the center leg comprises at least one coolant inlet, wherein each of the side legs and the center leg comprises an internal coolant channel providing a fluid communication between the at least one coolant nozzle and the at least one coolant inlet, and wherein the at least one coolant inlet of the center leg is connected to a coolant conduit-configured to supply a coolant to the coolant inlet, and wherein the coolant conduit has a longitudinal axis extending orthogonally to the center leg and parallel to the rotational axis. ### Claim 16 (depends on 12) The grinding machine according to claim 12, wherein the center leg comprises at least one coolant inlet, wherein each of the side legs and the center leg comprises an internal coolant channel providing a fluid communication between the at least one coolant nozzle and the at least one coolant inlet, wherein the at least one coolant inlet of the center leg is connected to a coolant conduit-configured to supply a coolant to the coolant inlet, and wherein the coolant conduit has a longitudinal axis extending orthogonally to the center leg and parallel to the rotational axis, wherein the center leg is rotatably supported, and wherein an axis of rotation of the center leg is said rotational axis.
