The utility model relates to equipment for machining a micro cavity of a mold by combining machinery and laser, which comprises a numerical control machine tool for mechanically milling the micro cavity and an ultrafast laser precision machining device for precisely machining the micro cavity, wherein the numerical control machine tool is provided with a supporting clamp for fixing a concave template, and the ultrafast laser precision machining system comprises a laser, a three-dimensional confocal imaging module for imaging acquisition and an imaging processing system for image analysis. A shutter, an attenuator and a quarter-wave plate are sequentially arranged on the output optical path of the laser, the output optical path of the quarter-wave plate is connected with a scanning galvanometer, and a focusing mirror is arranged at the output end of the scanning galvanometer, and the focusing mirror is opposite to the supporting fixture; The three-dimensional confocal imaging module faces the supporting fixture and is in communication connection with an imaging processing system which is in communication connection with a laser. First, mechanical rough milling is performed, and then the micro cavity of the mold is precisely machined on line by confocal three-dimensional vision inspection and ultrafast laser.
