Abstract
A precision drill for drilling noncircular bores, comprising a drill bit on a shaft and a holder for the workpiece being drilled, for providing a drill that can operate economically at high speeds. The workpiece holder oscillates translationally in at least one direction at a frequency controlled by the speed of the drill bit, and moves along a path determined by the desired shape of the bore to be drilled.
Claims3
Precision drilling machine with a drilling bit on a drilling spindle and a holder for a workpiece to be worked for drilling noncircular bores, characterized in that the holder (6) for the workpiece (5) oscillates in a least one direction translatorily with a frequency proportional to the given number of revolutions per minute of the drilling bit (3) and in a path of deflection dependent on the shape of the bore to be drilled.
