ABSTRACT:
The present invention relates to a tool/collet alignment and securement arrangement for a vertical milling machine having a J-head and a manually adjustable spindle for the secure and rapid change of a tool held in a collet in a lower end of the spindle. An arrangement of receiving bores are spaced annularly around the lower end of the spindle. An arrangement of locating pins are correspondingly arranged about the tool/collet so as to mate with the receiving bores in the spindle, to provide secure and efficient engagement of the collet/tool with the spindle in the vertical milling machine.
