To provide a box tree pattern processing machine shortening a processing time, a program for controlling the same and a timepiece component.

A plurality of grinding mechanisms 11 equipped with motors 12 for rotationally driving rubber grinders are provided, a plurality of processing tables 20 are provided corresponding to these grinding mechanisms 11, and the grinding mechanisms 11 are moved to the processing tables 20 along three directions crossing each other at a right angle by sliders 32, 33 and 34 while keeping the mutual positional relations between the grinding mechanisms 11. By this constitution, the time required for processing a back lid being a member to be processed becomes short as compared with processing due to manual work and, since a plurality of back lids are processed at the same time, the number of the back lids capable of being processed within the same time is markedly increased and a processing time is sharply shortened.
