The present application relates to the technical field of laser processing, and discloses a laser processing machine and a laser processing method for diamond composite plane teeth, wherein the laser processing method reduces the possibility of processing path overlap through the cooperative work of a scanning galvanometer module and a machine tool mechanical shaft, and avoids the chromatic aberration problem caused thereby. The scanning galvanometer module is used to control the position of the laser focal point, so that the laser cutting path can be more accurately controlled, thereby improving the processing precision, avoiding the problems caused by low mechanical shaft feeding precision in the traditional single-point processing mode, reducing the risk of excessive cutting filling, and ensuring the cutting quality within the processing boundary. The laser processing machine of the present application processes diamond composite plane teeth by using the above-mentioned laser processing method, so that the processing boundary is clear, and the problems of excessive cutting filling and chromatic aberration are avoided.
