摘要： Cryogenic fluids are delivered along an axial path through a machine tool spindle to a cutting tool that is mounted in a standard tool holder. An external source of cryogen is delivered via an insulated line to a junction block housing where the cryogen flows into a vacuum insulated coolant delivery tube mounted on the axis of rotation of the spindle. The coolant delivery tube couples with a cryogenic manifold located in a standard tool holder in the end of the spindle. The cryogenic manifold couples the cryogen to a tool that is mounted in the tool holder. Before a tool change operation, the coolant delivery tube is raised to disconnect it from the cryogenic manifold, and to turn off the flow of cryogen to the delivery tube.
