ABSTRACT:
Method of and tool for the precise and finish processing of profiled cylindrical holes in a metal workpiece, wherein the length to billet diameter ratio of the hole is larger than 3. In accordance with the method of the invention, there is preliminary chip removal along the hole being processed, and the hole is later plastically deformed by fluid fed to the deformation zone thereof under high pressure. Fluid under high pressure is also fed to the zone of chip removal and is directed toward the chips removed from the material.
The tool for carrying out the method comprises guiding, cutting, deforming and sizing parts disposed in such sequence and mounted upon a tool body. The tool body is provided with a blind axial hole through which the fluid under high pressure is supplied to the deformation zone of the hole in the workpiece and to the zone of chip removal where it is directed toward the chips removed from the material of the workpiece.
