摘要

PROBLEM TO BE SOLVED: To provide a method for working a camshaft hole of a cylinder head by which the camshaft hole can be formed in a state that the cylinder head is deformed to the same level as when it is bolted and fixed to a cylinder block without increasing manufacturing costs.;SOLUTION: The cylinder head 1 is fastened and fixed to a pallet 11, on which the cylinder head 1 is placed during working, with a bolt 13 inserted to a bolt hole 12 which is formed to the cylinder head 1 and for fixing to the cylinder block. The cylinder head 1 is made into the same deformed state as when the cylinder head 1 is actually mounted to a prescribed cylinder block. The camshaft hole 7 is worked to the cylinder head 1 in that state.;COPYRIGHT: (C)2005,JPO&NCIPI
