Abstract: A guided member is engaged with a guiding member and the guided member and guiding members are movable relative to each other. A pair of planar, parallel guide surfaces on the guide member are engaged by a pair of bearings mounted on the guided member. One of the bearings is resiliently biased into engagement with the guide surface which is less precisely formed so that irregularities in that guide surface or lack of parallelism between the guide surfaces is accommodated by displacement of the biased bearing. The bearings are mounted on bearing supports which depend from either side of a cross piece. The cross piece is secured to the guided member such that a portion of the cross piece is uncoupled from the guided member and is free to be deflected, thus providing the biasing for the biased bearing without transmitting stress to the guided member. Preferably, the apparatus is employed in a machine tool to guide the movement of a worktable.

Abstract: A drill may be fed into a workpiece at a rate where the angle descent is less than the primary relief angle of the drill and wherein the extruding action takes place in 1/3 or less of the drill diameter. Unachieved rates of drill feed speed with high precision may be achieved without punching or crushing the material of the workpiece. In order to accomplish such drilling rates an improved feed mechanism, utilizing a positively driven lead screw is employed. In addition, in order to utilize the high drilling rate, a multiple bank of spindles is devised having an X-Y adjustable configuration used in combination with a worktable translated by a lead screw and nut combination. The lead screw of the worktable is disposed within the worktable in the proximity of the axis of symmetry to the worktable in order to minimize twisting moments to the worktable.

The drill head and work engaging head are adjustable as a unit in a vertical direction relative to the carriage to vertically position the drill and work engaging head. The relative positions of the work engaging head and drill head are sensed to control the direction and speed of relative movement of the work engaging head relative to the drill head.

Abstract: A frame structure supports a work surface above which there is provided an elongated head number supporting a series of drills. A torque tube having an axis parallel to and spaced from a line passing through the series of drills is mounted to the frame structure for rotation about its axis. The drill head member is coupled to the torque tube such that rotation of the torque tube initially swings the head member in an arc and thereafter urges the head member through a lost motion coupling arrangement against a pair of spaced parallel guide rails, secured to the frame structure normal to the work surface so that the remaining travel of the drill head is rectilinear. The stiffness of the torque tube assures that one end of the elongated drill head will not move ahead or drop behind the other end so that all holes are drilled simultaneously.
