This invention comprises a control for moving a headstock longitudinally on a radial arm of a radial drilling machine and for moving the radial arm angularly about the axis of rotation, by moving the headstock a predetermined distance along an X--X axis and also moving said headstock a predetermined distance along a Y--Y axis at right angles to the X--X axis, for bringing the axis of the drill spindle on the headstock from one drilling position to another drilling position. One Servo motor moves the headstock on the X--X axis and another motor moves it on the Y--Y axis. The motors may be programmed to move said headstock automatically. When the headstock is moved on the radial arm along the Y--Y axis, angular movement of the radial arm is accompanied by movement of the headstock longitudinally of the radial arm. Thus, the movement of the headstock along X--X and Y--Y axes, also moves the radial arm angularly.
A control for a drilling machine having a radial arm, means to pivot said arm about a fixed axis, a drill headstock slidable on said radial arm and provided with a drill spindle parallel to said axis, said control comprising a first slide, means to mount said first slide for reciprocal movement in a plane at right angles to said fixed axis, means to reciprocate said first slide, a second slide, means to mount said second slide on the first slide for reciprocal movement at right angles to the direction of movement of the first slide and at right angles to said axis, means to reciprocate said second slide relative to the first slide, and means on the second slide for rotatable connection with the headstock about the axis of said spindle.
In combination, a radial arm drilling machine comprising a base, a column rotatably mounted on said base, a radial arm mounted on said column and rotatable therewith, a drill headstock slidable back and forth on said radial arm, a drill spindle rotatably and slidably mounted on said headstock and disposed parallel to the axis of rotation of said column, and control means for moving the axis of the spindle of said headstock only along X--Y axes to bring the spindle from one drill position to another and thereby rotate said arm from the angular position of said arm in said one drilling position to the angular position of said arm in said another drilling position and to cause said headstock to slide on said arm during movement of said axis of said spindle only along said X--Y axes.
In combination, a machine comprising an arm pivoted about a fixed axis of rotation, a cutting tool carrier slidable on said arm, a cutting tool mounted on said carrier on an axis parallel to said fixed axis, and control means to move the axis of said tool from one axial and radial predetermined position relative to the axis of rotation of the arm, to another axial and radial predetermined position relative to said axis, said control means comprising means to move said axis of said tool only along X--X and Y--Y axes, to thereby slidably move said carrier along said arm and to simultaneously rotate said arm about its axis of rotation.
