Guide rail guard for computer numerical control machine tools and manufacture method thereof

The invention discloses a guide rail guard for computer numerical control machine tools and a manufacture method thereof. The guide rail guard for computer numerical control machine tools involves a machine tool, threaded holes, guide rails, stepped holes, first bolts, slide grooves, sliders, mounting blocks, a first guard body, a second guard body, an insert, a receiving groove, positioning holes, a second bolt, a motor, fan blades, heat-dissipating holes, dustproof meshes, cleaning plates, limiting channels, moving racks, handles, springs, sponge pads, drain pipes, water guide pipes, water troughs, clamp blocks, clamp grooves and nonslip sleeves. The technical problem solved herein is that a guide rail guard of the prior art has poor heat-dissipating performance, cannot allow small waterdrops attached onto the surface of a workpiece to be timely cleared and is narrowly applicable; the guide rail guard for computer numerical control machine tools and the manufacture method thereof areprovided.
