ABSTRACT:
A lubrication ring, for use in a fabrication press having an assembly with a main cavity and a die nib disposed on a surface of the cavity for ironing a workpiece passing through the cavity, includes a groove surrounding a periphery of and opening into the main cavity of the assembly. At least one passage is provided for introducing a fluid into the groove so as to flow within the groove. The fluid is introduced into the groove at a velocity which causes a centrifugal force exceeding the force of gravity to act on the fluid flowing in the groove.
