ABSTRACT:
A jaw assembly includes a master jaw and a work clamping jaw bolted to the master jaw. The master jaw is formed along its axis with a cylindrical bore and in its top surface with an elongated hole having a width smaller than the diameter of the cylindrical bore and communicating with the cylindrical bore. At least one cylindrical seating nut having a diameter slightly smaller than that of the cylindrical bore is inserted therein. A fixing bolt is put through the work clamping jaw and the elongated hole of the master jaw and screwed into a threaded hole formed in the seating nut. The master jaw and the work clamping jaw can be coupled together in a position relative to each other that is adjustable by tightening the fixing bolt.
