PROBLEM TO BE SOLVED: To provide a biaxial hole machining method which can improve machining accuracy in machining a biaxial hole required to have a preset angular accuracy. SOLUTION: According to the biaxial hole machining method, a first reference surface 4e and a second reference surface 4b of a reference block 4 set in a pallet 1, and coordinate locations of a first axial hole H<SB>1</SB>of a workpiece W are detected before rotation of the pallet 1 in a downstream stage P<SB>2</SB>. After the rotation of the pallet 1, coordinate locations of each of the first reference surface 4e and the second reference surface 4b are detected. Then a correction value for correcting a rotation termination position of the pallet 1 is calculated based on the coordinate locations, and the pallet 1 is rotated again to correct the rotation termination position, followed by boring a second axial hole H<SB>2</SB>in the workpiece W.
