A collet closer assembly for a machine tool has a body adapted to be attached to a spindle of a machine tool. A pair of bores extend into the body from opposite ends thereof. A collet is received into the bore at the distal end of the body and is immovably attached to the body. A closing sleeve extends from the distal end of the body and encircles the collet. A collet housing is attached to the distal end of the body to enclose the collet sleeve. A slide member is positioned in the bore at the proximal end of the body, and the slide member is adapted to be attached to the end of a draw bar of the machine tool. A mechanical linkage connects the slide member and the collet sleeve so that the collet sleeve moves in concert and in conjunction with the slide member and the draw bar. The collet sleeve closes and opens the collet as the collet sleeve moves forward and backward, respectively. The collet does not move relative to the spindle of the machine tool during opening and closing of the collet, but instead maintains a precise, accurate position relative to the spindle of the machine tool.
