Abstract
A portable single point facing tool (10) includes a drive system (12,18), a rotating base member (14), a feed control mechanism (40) and a tilting cutting head (32) with a cutting tool (30). The tool feed is driven through a gear system (84,86) synchronously with rotation of the base member, a variable throw crank mechanism (82) and a drive rod (83) so that tool feed rate is infinitely variable relative to speed of rotation of the base member. Direction of tool feed can selectively be set at forward, reverse or zero feed by means of a selectively engageable gear train associated with the feed mechanism (40).
