A device and method for aligning the machine head of machines such as milling machines. A disk having a lapped flat surface is to be attached to the spindle of the machine, and the axis of the spindle can readily and accurately be set perpendicular to the two milling machine table axes. A hub is attached to the disk, with an axis vertical to the flat surface. The hub is used to attach the disk to the spindle. The disk has a plurality of equally spaced indicia around near its edge so that the high point and low point can be determined by placing a feeler gage on the machine table and tracking the flat surface. An axis accurately perpendicular to the machine head axis (spindle axis) will exist half-way between the high and low points on the edge disk as determined by the feeler gage. The machine head may now be accurately adjusted relative to the table by adjusting it so that a feeler gage shows no variation when the said perpendicular axis is tracked in the two milling machine table axial directions. Lightly magnetized angle blocks may also be provided to set the spindle to any angle after a particular alignment has been completed.
