  • 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.

  • Patent number: 9157817
    Abstract: An assembly may comprise a head stack assembly (HSA) swaging tester device, comprising a base and a top tooling assembly connected thereto. The top tooling assembly may comprise an actuator motor; a load cell connected to the actuator motor; and a force gauge connected to the load cell, the force gauge being configured to measure torque imparted by the actuator motor on an HSA under manufacture. The force gauge of the HSA swaging tester device may be calibrated according to a selected type of HSA to undergo the swaging procedure by coupling a selected reference torque assembly to an axle connected to the actuator motor, the selected reference torque assembly being configured to impart a known torque onto the axle. The force gauge may then be adjusted (e.g., calibrated) according to the known torque imparted upon the axle by the selected reference torque assembly.
