Processing technology for deep hole and groove of temperature measuring element of nuclear main pump sealing chamber

The invention relates to a processing technology for deep holes and grooves of a temperature measuring element of a nuclear main pump sealing chamber, which comprises the following steps of: configuring an angle head, a three-edge milling cutter and a plurality of cutters for a processing center to complete the processing of the deep holes and grooves of multiple layers of the sealing chamber, and fixing the sealing chamber (1) on a workbench (21) of the processing center; the angle head (16) is installed on a machining center (20), a face and edge milling cutter (19) with the diameter of 100 mm is installed on the angle head (16), and the position, where the temperature measuring hole (5) is machined, of the inner-layer arc face (2) is machined into a plane through the face and edge milling cutter (19). Multi-layer deep hole machining with the high precision requirement is achieved, the drilling mode is stable, professional deep hole machining machine tools are saved, the cost is saved for enterprises, the m
