ABSTRACT:
A machine for engraving or milling surfaces has been devised which is particularly adaptable for tire mold milling and more specifically wherein a drive spindle for a cutting tool is caused to undergo vertical or horizontal oscillation under the control of an overhead slider crank mechanism in direct correlation with the rotational movement imparted to a table support for the tire mold. The engraving tool is suspended from the work head in such a way as to be shiftable to a selected radius of curvature corresponding to the surface to be engraved, including both positive and negative radii of curvature; and is further capable of traversing either horizontal or vertical curved surfaces.
