The present invention provides an apparatus for machining a valve seat surface of a cylinder head. The apparatus for machining a valve seat surface of a cylinder head abrasively machines an annular valve seat surface formed on ends of multiple valve seats formed on a cylinder head to have exactly equal measured roundness from a center of the valve seat surface, and uses an integrated machining tool. The integrated machining tool comprises: a support guide inserted in the valve seats to be passed to a valve guide; an abrasive body comprising a support unit formed on an upper end of the support guide in an annular shape, whose outer diameter becomes gradually larger, a contact unit wherein an outer circumferential surface of an upper portion of the support unit has a shape corresponding to the valve seat surface, and a head unit which is disposed on an upper portion of the contact unit and has a prescribed height and an equal outer diameter; and an operating body comprising a handle shaft extended upwards from a center of the head unit of the abrasive body in a prescribed length, and a handle on an upper end of the handle shaft. |
