  • De-swage machine for removal of a head from a head stack assembly and method of using the same
    Patent number: 9308609
    Abstract: A de-swage machine for removal of a head of a head stack assembly including a tooling unit configured to receive a head stack assembly comprising a plurality of heads and an indicia, a blade module configured to remove a head from the head stack assembly, an indicia reader configured to read the indicia, and a controller. The controller is configured to select and remove a head from the head stack assembly by at least reading the indicia using the indicia reader, transmitting the indicia to a database, receiving head stack assembly information corresponding to the indicia from the database, selecting the head for removal based on the head stack assembly information, and removing the selected head using the blade module. The blade module can also include a force sensor, and the de-swage machine can also include an imaging unit.
