Summary: | The Y shaft structure of PCB drilling machine includes machine body, work stable, linear tracks, linear block, track installing seat, and integral work stable embedding board in the length direction of the machine body and of the same material as that of the machine body. The work table is installed on the work stable embedding board, and the linear block below it. The present invention has no transfer of heat deformation and heat stress of the metal work stable to the linear block and the linear tracks, and the work stable embedding board with the same thermal expansion coefficient and deformation rate as the machine body. The machine can maintain its machining precision in varying environment temperature. |
