ABSTRACT:
A workpiece cutting apparatus including a spindle-supporting assembly, a rotatable spindle mounted within the assembly and a cutting tool supported by the spindle utilizes a network of passages defined in the spindle-supporting assembly, the spindle and cutting tool for effectively introducing a lubricating and/or cooling fluid into the region of a workpiece being cut by the cutting edge of the cutting tool. The spindle-supporting assembly includes a collar having an opening through which a portion of the spindle is rotatably received, and the surface of the opening defines an annular groove encircling the spindle into which fluid is directed. The surfaces of the groove and spindle define an annular cavity, and the spindle defines a passageway defining an opening which is in constant communication with the annular cavity. The cutting tool defines a conduit having an entrance in flow communication with the spindle passageway and an exit positioned adjacent the cutting edge of the cutting tool. Fluid directed into the annular cavity thereby travels a continuous path through the spindle and cutting tool and exits the cutting tool at a location adjacent the cutting edge thereof.
