| titleOfInvention | Method and apparatus for stitch-machining deep cavities in metal workpieces |
| abstract | Abstract of the Disclosure Stitch-machining the walls of a cylindrical blind cavity of a workpiece, the cavity being deep and narrow with respect to the axis of the cavity, is carried out by: (a) supporting a tubular housing for axial movement throughout substantially the axial extent of the cavity interior and in close-fitting tolerance to the walls of the cavity, the tubular housing having a free end; (b) rotationally driving a spindle (10,000-40,000. rpm) in the tubular housing for conjoint axial movement with the tubular housing, the spindle extending beyond the housing end for carrying a radially adjustable cutting tool; (c) inserting the tubular housing together with the rotationally driven spindle into the cavity (at lineal speeds of 400-800 inches/minute) with a cutting tool radially positioned for rough boring of the cavity walls, while guiding and steering the tubular housing and spindle to accurately concentrically position the cutting tool with respect to the cavity axis; (d) substantially immediately upon the execution of rough boring, withdrawing the tubular housing together with the rotationally driven spindle from the cavity with the cutting tool repositioned for finish boring of the cavity wall during withdrawal; and (e) upon substantial execution of finish boring and withdrawal of the tubular housing and spindle into a fixed housing positioned closely adjacent the face of the workpiece, moving said workpiece relatively transversely with respect to the axis of the spindle for carrying out milling while radially adjusting the cutting tool for milling of the face, the tubular housing being guided and steered within the fixed housing to attain close milling tolerances. 2267L. |
