Abstract
A base material has a vibration damper provided detachably on a liner through an attaching surface. An apparatus is used when punching the vibration damper piece from the base material. The punched vibration damper piece is attached on an objective portion of a semi-finished head suspension. The apparatus includes a hollow punch and a punch drive mechanism. The hollow punch has a tooth portion at a distal end and a hollow internal surface that has a holding force larger than an attaching force of the vibration damper to the liner. The hollow punch punches the vibration damper piece out from the base material to hold the vibration damper piece on the hollow internal surface. The punch drive mechanism drives the hollow punch backward and forward in a punching direction, so that the vibration damper piece is punched with the tooth portion without punching out the liner.
