A method of adjusting a machine tool. The method adjusts the machine tool so that, in ultra-precision machining of round bar-like work (W), the machine tool can rotate the work (W) while suppressing run-out of the axis of the work (W). In an axis position adjustment step (S5), a side surface of a projection portion of the work (W) held by a work holding mechanism (50) is measured while a work spindle (40) is rotated. A C-shaft adjustment screw (42b) is adjusted so that run-out of the work (W) is minimum and then the position of the work axis (C2) is fixed. In a support adjustment step (S6), with the position of the work axis (C2) fixed, a support block (91) is adjusted so as to support the work (W). In a support locking step (S7), the definition of the position of the work axis (C2) defined by the support block (91) is maintained by pressing the work (W) by a work presser (92). In a floating-restriction releasing step (S8), floating restriction by the C-axis adjustment screw (42b) is released. |
