  • Adaptive drilling with piezo-electric feed oscillator
    Patent number: 10232446
    Abstract: A positive feed tool may include a motor, a power supply operably coupled to the motor to power the motor, a gear head and a spindle. The gear head may be operably coupled to the motor to be operated responsive to powering of the motor. The gear head may include a drive assembly and a feed assembly. The spindle may be operably coupled to the gear head to enable the spindle to be selectively driven rotationally and fed axially based on operation of the drive assembly and the feed assembly, respectively. The feed assembly may include an electronically controlled variable feed rate oscillator.
