High-precision drilling machine

The high-precision drilling machine comprises a bottom plate and a machine body, the machine body is fixedly connected to the top of the bottom plate, a workbench is fixedly connected to the surface of the machine body, a shock absorption mechanism is arranged at the top of the bottom plate, and the shock absorption mechanism is fixedly connected with the workbench; the shock absorption mechanism comprises a plurality of shock absorption sleeves fixedly connected to the top of the bottom plate, the shock absorption sleeves are evenly distributed on the top of the bottom plate, lifting holes are formed in the tops of the shock absorption sleeves, and transmission rods are arranged in the lifting holes in a sleeved mode. By arranging the shock absorption mechanism, shock of the working table can be buffered and absorbed through the compression spring and the two strong magnetic blocks, and the shock of the compression spring and the two strong magnetic blocks can be attenuated through the damping effect generat
