Abstract
Deburring apparatus for removing the burrs which are formed at the intersecting inner edges of at least two intersecting bores of a workpiece comprises; a frame having means for holding the workpiece; a cutter spindle borne rotatably in the frame; a cutter hinged to the leading end portion of the cutter spindle and biased to swing outwardly of the side thereof for cutting off the burrs at the inner edges of the bores of the workpiece held by the holding means of the frame when the cutter spindle is inserted into one of the bores and rotated; and a guide sleeve fitted slidably on the cutter spindle for sheathing the cutter, when the cutter spindle is inserted into or retracted out of the one of the bores, to protect the inner walls of the workpiece from damage, and for exposing the edge of the cutter to the outside when in the deburring operation. The cutter is directed along a curve of the inner edges of the bore of the workpiece by a cam on the frame engaged by a follower on the cutter spindle. A three-dimensional curve of the inner edges can be deburred precisely.
