FIELD: machine engineering.
SUBSTANCE: device for grinding the surfaces of the pipeline fittings, contains a faceplate with the working disks evenly located around the circumference. The faceplate is rotationally driven by the spindle pivotally attached thereto and pressed to the faceplate via a spring. The upper clips of a diamagnetic material are rigidly fixed on the periphery of the faceplate end surface, with permanent magnets rigidly fixed therein . The lower clips are inserted into the upper clips of the diamagnetic material with permanent magnets rigidly fixed therein . The magnets in the said clips are arranged with uniform poles to each other. At least, six working discs with sandpaper are rigidly fixed in the lower clips.
EFFECT: enhanced processing quality of pipeline valve sealing.
