ABSTRACT:
A machine tool has a work table movable in a first direction on a frame. Operating units such as drills fitted with rotating tools are mounted on the frame in a manner movable in a direction perpendicular to the said first direction. Means are provided to ensure individual mobility of the operating units namely individual motors incorporated within their casings. The invention is useful in the machining of printed circuits especially by drilling and shaping.
