Abstract
An optical calibration and testing device for machine tools includes a light source unit, a beam splitter, and at least one photo detector. The light source emits a laser light hitting the beam splitter and is split into two beams. One is perpendicular to the foundation of the light source unit, and the other is parallel with the foundation so as to test straightness, inclination angle, verticalness, vertical column inclination, vertical column parallelism and guide bar inclination of a machine tool. If there is no tested error, the position of the testing light spot coincides with that of the initial light spot. If there is an error, the position of testing light spot varies according to the error.
