Abstract
A milling tool is disclosed. The tool may include a base including a clamp for coupling to a selected mounting slot of a plurality of slots of the rotor; a milling tool including a motorized milling head; and a motorized linear actuator coupling the milling tool to the base. The base mounts the motorized linear actuator at an acute angle relative a portion of the slot to allow the motorized linear actuator to linearly move the milling tool to machine the portion of the slot. The portion of the slot may include, for example, an end face and, more particularly, a root corner of the slot where a cooling slot flange extends from the root of the slot. The milling tool may be portable.
Claims22
A milling tool apparatus for a slot in a rotor, the milling tool apparatus comprising:
- a base including a clamp for coupling to a selected mounting slot of a plurality of slots of the rotor;
- a milling tool including a motorized milling head;
- and
- a motorized linear actuator coupling the milling tool to the base,
- wherein the base mounts the motorized linear actuator at an acute angle relative to an end face of the slot to allow the motorized linear actuator to linearly move the milling tool to machine a portion of the slot,
- wherein the clamp is configured to hold the base in position relative to the selected mounting slot.
