Abstract
A universal sharpening, grinding and milling machine comprises a horizontal table having a vertical column mounted for a limited vertical and horizontal movement relative to the table. A tool-carrying head including a shaft carrying tools at both ends and a motor for driving the shaft can be removably mounted on the column in selected angular positions about the axis of a tie-bolt by which the head is mounted, and with either of two opposed faces of the head facing the column. The tools are spaced by different distances from said tie bolt axis, and the axis of the shaft is spaced by different distances from the opposed faces of the head, whereby the possibilities of positioning a tool relative to the table are increased for limited paths of movement between the column and table. An auxiliary table can be provided to facilitate turning about the tool-carrying head, and vertical movement of the column can be provided by a pawl-and-ratchet device controlled by rocking a crank.
