A tool for drilling, tapping, and back spot facing a hole in dynamoelectric machines includes a servo motor cutting device and a drill unit skid. The servo motor cutting device includes a cutting tool. The drill unit skid engages a hook fit slot in a case of the dynamoelectric machine and supports the servo motor cutting device. The drill unit skid includes hook fit slides configured to guide the drill unit skid along the hook fit slot and act as a stop in a radial direction. The tool includes a laser positioning device configured to detect the position of the cutting tool, and a micro switch configured to stop the servo motor cutting device when the micro switch activates. The servo motor cutting device rotates the cutting tool to create the hole, and a rotor of the dynamoelectric machine is left in place during drilling, tapping and back spot facing. |
