摘要：PURPOSE:To allow a feeding tool to correspond to a variety of diameter of tapped holes by forming the top edge of a nozzle into veral stages and allowing a paste sink to lectively communicate to the nozzle, in a tap-paste feeding tool which is ud in a machining center, etc. CONSTITUTION:When the tapped hole Wa on a workpiece W is positioned and a main spindle is positioned on the hole Wa, the main spindle stops when a nozzle 9 is pushed-in by a prescribed amount into the port of the hole Wa. In this state, a paste feeding passage 9i communicates to a feeding passage 9j, and pressureized air is fed from air holes 2a, 1b, and 1c, and a piston 5 is advanced. Therefore, paste is fed from feeding passages 4c, 9j, and 9i into the hole Wa. When the prehole for the next tapping work is positioned directly under the main spindle, the cylinder 9c of the nozzle 9 is inrted into the hole, and the stage 9b is brought into contact with the port part. Therefore, the feeding hole 9j communicates to the opening part of a feeding passage 9h, and paste is supplied into the prehole from the feeding passages 9j and 9h.
