Abstract: PURPOSE: A machining tool chuck for a retainer ring of a vertical lathe is provided to improve processing efficiency of a retainer ring by rotating an insertion block and property replacing cutting blades according to processing of a retainer ring. CONSTITUTION: A machining tool chuck for a retainer ring of a vertical lathe comprises a gripping member(10), an insertion block(30), and a cutting edge fixing bolt(40). The gripping member has first and second walls(13,19) and a stop ball(15). The insertion block is installed in a space between the first and second wall parts of the gripping member to rotate. The insertion block has a guide groove, a plurality of seating grooves, a cutting edge mounting groove(35), and a rotation preventing groove(37). The guide groove is formed on one surface facing the inside of the first wall portion. The seating grooves are formed in the guide groove in a regular interval. The stop ball is inserted into the seating groove. The cutting edge mounting groove is formed along the center of the rim face. A plurality of cutting edges is inserted into the cutting edge mounting groove. The cutting edge fixing bolt is inserted into the insertion block. The cutting edge fixing bolt fixes the cutting edge, inserted in the cutting edge mounting groove, on the insertion block.
