Abstract

PURPOSE:To prevent the reduction in a working accuracy due to the variance of focal distance, etc., by reducing the working error caused by an eccentric rotation or revolving a focusing lens by rotating a condensing lens integrally with a rotational body without the medium of a bearing body. CONSTITUTION:The XY coordinate value of the center position of a working part, the eccentricity amt., the rotary speed of a laser, etc., are first inputted to a NC control part 76. With the actuation, then, a servomotor 32 stops by its rotation in the specified amt. by the command of the NC control part 76. The optical axis 45 of a condensing lens 43 is thus subjected to be not co-axial in the specified amt. A speed reducing rotation control part 80 is then actuated by the command from the NC control part 76, rotated at the specified rotary speed and the condensing lens 43 is eccentrically rotated. A signal is then transmitted to a laser oscillator 78 from the NC control part 76, a laser light 14 is projected on a work for the specified number of revolutions and the specified diameter hole working is completed.
