Abstract: A spindle and Z-axis unit comprises a spindle housing and a hollow rotor shaft rotatable and axially movable with respect to the spindle housing. The rotor shaft carries a collet at its lower end for chucking a machine tool such as a drill bit. The tool is changed in the collet by pneumatic actuation of a diaphragm which actuates a push rod within the rotor shaft to move the collet axially against a spring bias to clamp and unclamp the tool. The shaft is moved in the Z-direction along with a thrust bearing assembly by a screw nut which actuates a road to move the rotor shaft in the Z-direction to drill a workpiece after a pressure foot has first been moved to clamp the workpiece with respect to the spindle. Thus, the moving weight or mass previously attributable to parts such as a spindle saddle and spindle housing can be eliminated without impairing the reliability and chucking force of the collet mechanism.

Abstract: A method and apparatus for dispensing a smear-preventing solution onto a drill bit used for drilling printed circuit boards includes a drilling jig having a drill bit for engaging the printed circuit board and a dispensing system for dispensing a smear-preventing solution under pressure so that it sprays onto the drill bit through a hole in a pressure foot as the drill bit engages the printed circuit board. A switch mounted on the drilling jig controls the dispensing of the solution so that the solution is dispensed during the time that the drill bit is in the vicinity of the printed circuit board, and is turned off when the drill bit leaves the printed circuit board, or when the drill is turned off. A vacuum hose connected to the housing creates a low pressure condition adjacent the drill bit which provides for coating the drill bit while the solution is being dispensed, and for pulling the excess solution and debris created by the drill bit away from the surface of the printed circuit board.

Abstract: A drilling spindle having a pressure foot is disclosed for handling drilling tools having relatively large diameter shank regions and relatively small diameter drilling bit portions regions. The pressure foot assembly includes a shutter plate which contacts and clamps the workpiece during drilling operations.

The small aperture is sized to receive the drilling tool region of the drill, and permits the drilling region to be extended therethrough while providing good clamping of the workpiece during drilling. The large aperture is sized to receive the shank region of the tool, and permits the tool to be inserted or withdrawn from the spindle during tool changing operations.

Ultrasonic vibration is applied to the printed circuit board via the stand during the drilling operation to prevent the occurrence of expoxy smearing.
