Sub plate assembly for machine tools

摘要

The disclosure relates to a tooling set up and subplate means for machine tools wherein a subplate is provided with intersecting rows of openings; said rows precisely intersecting each other at right angles and some of said openings having precision locating bushings therein and others of said fixture openings being internally screwthreaded fixture openings. The locating openings are in rows adapted to be precisely aligned with the two axes of movement of the machine tool table and hold down means adapted to secure said subplate on the machine tool table and tooling members having fixture receiving openings and locating openings adapted to coincide with the respective openings in said subplate so as to precisely align tooling with the movement axes of a machine tool and to thereby alleviate the time usually devoted to the alignment of a piece of work on a machine tool with respect to its directions of movement.
