Numerically-controlled machine tool shell

The numerical control machine tool shell comprises a base, a bottom plate is movably installed on the top of the base, a first protection shell is fixedly connected to the left side of the top of the bottom plate, a second protection shell is fixedly connected to the right side of the top of the bottom plate, and the right side of the first protection shell is movably connected with the left side of the second protection shell in a clamped mode. According to the numerical control machine tool, generated iron chips, welding slag, dust and other particles can be adsorbed through the exhaust fan when the numerical control machine tool is operated, and the particles can directly enter the filter box through the pipeline and can be effectively filtered while passing through the filter adsorption net plate; and fan blades can be driven to blow air into the device through the output shaft, particles such as scrap iron can be blown up to achieve the rapid adsorption effect, meanwhile, the problem that dust removal an
