ABSTRACT:
A machine tool has a main slide movable along a first path and a cross-slide assembly movable perpendicular to the path of the main slide. The cross-slide assembly has a first slide unit which is directly driven by a primary servo control. The cross-slide assembly has a second slide unit driven by the first slide unit through a spring-loaded follower acting against a cam which can transmit numerically-controlled offset to the second slide unit such that both slide units will follow identical paths. The cam is adjustable to enable correction of the offset. Each slide unit carries a cutting tool. The invention is applicable to multiple spindle machines having two or more spindles.
