METHOD AND TOOL FOR USE WITH TURBOMACHINES

摘要

A tool for drilling, tapping, and back spot facing at least one hole in a turbomachine includes a servo motor cutting device configured for use with a cutting tool. A drill unit skid is adapted to engage a hook fit slot in a case of the turbomachine, and for supporting the servo motor cutting device, and the drill unit skid including hook fit slides. The hook fit slides guide the drill unit skid along the hook fit slot and act as a stop in a radial direction with respect to the turbomachine. A laser positioning device detects the position of the cutting tool. A micro switch stops the servo motor cutting device when the micro switch activates. The servo motor cutting device rotates the cutting tool to create the hole, while a rotor of the turbomachine is left in place during drilling, tapping and back spot facing.
