Horizontal machine tool

The utility model relates to the technical field of machine tools, and discloses a horizontal machine tool which comprises a horizontal machine tool body, a pump body and a universal spray pipe are installed on the horizontal machine tool body, the output end of the pump body is communicated with the universal spray pipe through a pipeline, and a proportioning valve is assembled on the pipeline. A supporting assembly and a feedback assembly which are matched with each other are arranged on the horizontal machine tool body. According to the horizontal machine tool, a traditional machine tool structure is replaced, when the rotating speed of a workpiece is low, little cooling liquid is sprayed out through the pipeline and the universal spraying pipe, when the rotating speed of the workpiece is high, much cooling liquid is sprayed out through the pipeline and the universal spraying pipe, and on the premise that the cooling effect of the cooling liquid on the workpiece is guaranteed, the cooling efficiency is imp
