SPINDLE SHAPING OF TITANIUM SHEET

摘要

Spindle shaping is a hand-fed, edge-profiling operation for certain types of sheet-metal parts. The blank is firmly clamped to a template of desired edge contour. By means of a suitable fixture, the template and blank are then hand fed into an inverted single-spindle cutter protruding through a table. A bearing surface on the milling-type cutter traces the contour of the template, thereby guiding the cutter as it cuts the profile of the part.nParts can be produced from titanium and titanium-alloy sheet with aircraft-quality edge finish. This method is feasible for shaping sheet metal in gages from 0.060 to 0.187 inch using carbide cutters and carbon dioxide as a coolant.
