Abstract
An apparatus for lapping sliders comprises a rotatable lapping plate for lapping elements that are to be formed into sliders, a pushing force adjusting member that has an internal space therein and that extends vertically along an lapping plate axis that is perpendicular to the lapping plate, a pusher for pressing the elements, the pusher being connected to the pushing force adjusting member, and gas supply means for supplying a gas into the internal space, the gas supply means being connected to the pushing force adjusting member. The pushing force adjusting member comprises a first part that includes a connection with the pusher, a second part that includes a coupling between the internal space and the gas supply means, and an axially deformable part that is located between the first part and the second part. A length of the axially deformable part changes in a direction of the lapping plate axis in accordance with pressure in the internal space such that deformation of the axially deformable part causes a change in the pushing force of the pushing force adjusting member against the pusher.
