Vacuum-hydrostatic shoe for centerless grinding |
摘要 |
A vacuum-hydrostatic shoe especially suited for supporting a workpiece in metalworking operations is disclosed. The vacuum-hydrostatic shoe is comprised of a body with a support surface confronting the workpiece. Preferably the support surface is shaped to substantially conform to the workpiece shape. The shoe body comprises hydrostatic pockets. Each hydrostatic pocket has a first pressure opening defined in the support surface and a second pressure opening fluidly connected to a respective first pressure opening. The second pressure openings are also fluidly connected to a supply of pressurized fluid so that a flow of pressurized fluid can be created between the shoe body and the workpiece. The shoe body further comprises a vacuum pocket. The vacuum pocket has a first vacuum opening defined in the support surface and a fluidly connected second vacuum opening. The second vacuum opening is also fluidly connected to a source of vacuum to create a vacuum pressure between the shoe body and workpiece. The vacuum-hydrostatic shoe creates a hydrostatic pressure to provide a non-contact support to the workpiece and a vacuum pressure to preload and stabilize the workpiece.
