Abstract:
1. An apparatus for delivering coolant to the area of contact between a workpiece and a contact zone of a rotatable tool on a machine during a machining process, wherein at least two different contact zones of said tool are utilized in the machining of said workpiece, said apparatus comprising: a plurality of coolant nozzles positionable to direct coolant to the area of contact between the workpiece and the contact zone of the tool, positioning means for changing the position of said plurality of coolant nozzles concurrently with a change to another contact zone of said tool, whereby during machining with said another contact zone of said tool, coolant is directed to the area of contact between the workpiece and said another contact zone, wherein said plurality of coolant nozzles are attached to and in fluid communication with a coolant header, said coolant header being positionable with said plurality of coolant nozzles, and wherein movement from one contact zone to another contact zone on said tool comprises movement of said tool relative to the workpiece along at least one axis of motion on the machine, the repositioning of said plurality of coolant nozzles being synchronized with said movement of said tool along said at least one axis wherein a defined amount of movement of said tool yields a predetermined amount of repositioning movement of said plurality of coolant nozzles.
