The invention provides wiredrawing tank grinding equipment. The wiredrawing tank grinding equipment comprises a spindle, a moving device, an axial moving platform and a protective cover, wherein the spindle is mounted at the upper end of a supporting block through two bearings, and the two bearings are located in the middle of the spindle; the moving device comprises a base, and the upper end of the base is connected with the axial moving platform in a sliding mode; a radial rail rest is fixedly connected to the axial moving platform, the upper end of the radial rail rest is connected with a mounting platform in a sliding mode, and a grinding wheel is fixedly connected to the mounting platform; the axial moving platform does reciprocating movement in the axial direction of the spindle; the mounting platform does reciprocating movement in the radial direction of the spindle to get close to the end, provided with a clamp nut, of the spindle; the grinding wheel is mounted on the moving device; and the protective cover is provided with a transparent observation window and is connected with an upper guide rail and a lower guide rail in a sliding mode. According to the wiredrawing tank grinding equipment, the protective cover can prevent metal chips produced after grinding from flying towards operators, so that the safety of the wiredrawing tank grinding equipment is improved. Meanwhile, the phenomenon that the sidewalls of outer circles of ground wiredrawing tanks are unsmooth can be avoided.
