Abstract

The invention relates to a cylinder head and a method for manufacturing the same. The method includes: preparing a cylinder head casting having an intake passage, an exhaust passage, and a combustionchamber by casting using a mold and a plurality of cores; machining an intake port, an intake valve seat, an intake valve guide bore, an exhaust port, an exhaust valve seat, and an exhaust valve guidebore in the cylinder head casting by a first cylindrical tool; and forming a tapered surface on a portion of edge of the intake port by a second cylindrical tool. In particular, the second cylindrical tool moves along a predetermined trajectory at the edge portion of the intake port and rotates around an axis simultaneously to machine the tapered surface.
