Abstract:
1. A metal machining apparatus for removal of metal from a workpiece during a machining operation, comprising: 1) a holder for a workpiece, 2) a metalworking tool that is configured to engage the workpiece along a machining interface to remove metal from the workpiece, 3) a coolant nozzle for emitting a stream of a cooling liquid, the nozzle comprising a nozzle body having a flow passage and a laser bore, wherein the flow passage has an inlet and an outlet, and wherein the laser bore has an access opening in fluid communication with the flow passage at an intersection, and provides a line of sight along the laser bore to the flow passage outlet, 4) a removable plug inserted into the laser bore through the access opening to seal the access opening during the machining operation while the emitted stream of cooling liquid is directed at the machining interface, and 5) a visible laser that, prior to the machining operation, is removably inserted into the laser bore in place of the removable plug, and wherein the visible laser cooperates with the nozzle body by emitting a visible laser beam through the flow passage outlet for visually positioning the nozzle relative to the metalworking tool.
