THE PRESENT INVENTION RELATES TO AN AIR CHUCK ASSEMBLY (10). PARTICULARLY, THE PRESENT INVENTION RELATES TO A COMPUTERISED NUMERICAL CONTROL (CNC) LATHE AIR CHUCK ASSEMBLY. THE ASSEMBLY (10) COMPRISES AT LEAST SIX CYLINDRICAL PLATES (12, 16, 20, 24, 28, 32) WHICH ARE ATTACHED TOGETHER BY MEANS OF BOLTS. THE PROTRUSION (14) IS THREADED AT THE TOP. THE SECOND AND FOURTH CYLINDRICAL PLATES (16, 24) ARE THREADED ALONG THE PERIMETER OF THE OUTER PORTIONS (40, 42),RESPECTIVELY AND ALSO THREADED ALONG THE PERIMETER OF THE OUTER PORTIONS (44, 46) OF THE EXTENDED CAVITIES (18, 26), RESPECTIVELY. THE THIRD AND FIFTH CYLINDRICAL PLATES (20, 28) ARE THREADED ALONG THE PERIMETER OF THE INNER PORTIONS, RESPECTIVELY AND ALSO ALONG THE PERIMETER OF THE INNER PORTIONS (56, 58) OF THE CAVITIES (22, 30), RESPECTIVELY. THE FIFTH CYLINDRICAL PLATE (28) HAS A PROTRUSION ALONG THE PERIMETER OF THE FIFTH CYLINDRICAL PLATE (28) WHILST THE SIXTH CYLINDRICAL PLATE (32) IS THREADED ALONG THE PERIMETER OF THE INNER PORTION (60) OF THE SIXTH CYLINDRICAL PLATE (32). THE SECOND AND THE FOURTH MEMBERS (16, 24) ARE SMALLER IS SIZE COMPARED TO THE FIRST, THIRD, FIFTH AND SIXTH MEMBERS (12, 18, 28,32).(FIG 1)
