Numerical control machine tool with machine tool structural part cooling function

The utility model belongs to the field of machine tool equipment, and particularly relates to a numerical control machine tool with a machine tool structural part cooling function. Comprising a cross beam, stand columns, a lathe bed and linear axis motion devices, the cross beam is supported on the lathe bed through the left stand column and the right stand column, and the three linear axis motion devices act on the lathe bed and the cross beam respectively; wherein a plurality of cooling plates are arranged on the cross beam, the stand column and the lathe bed, and the cooling plates cover the outer surfaces of the cross beam, the stand column and the lathe bed one by one. The cooling device is simple in structure, easy to manufacture, convenient to disassemble, easy to maintain, low in cost, good in cooling effect and capable of effectively reducing thermal deformation of machine tool structural parts and further improving the machining precision of a machine tool. 本实用新型属于机床设备领域，特别涉及一种具有机床结构件冷却的数控机床。包括横梁、立柱
