Mechanically nutating drill driven by orbiting mass oscillator |
摘要 |
A drill bit is coupled at its upper end to an orbiting mass oscillator. The oscillator is mounted and connected to the bit such that the oscillator describes a conical orbiting path. The drill bit follows this conical orbiting path of the oscillator which results in a rolling nutating action of the bit cutters on the work material.
