Abstract
A method and apparatus for clamping and subsequently machining a disk- or ring-shaped workpiece, wherein the workpiece is set down on a contact surface of a contact member made from elastomeric material. The workpiece is axially pressed against the contact surface with an elastomeric-material clamping member of a clamping device and simultaneously fixed in place perpendicular to the workpiece axis. Subsequently, the workpiece is machined with a tool.
Claims5
A method for clamping and machining an annular workpiece, said workpiece having an inner diameter, an outer diameter and a central axis, said method comprising the steps of:
- locating said workpiece on an elastomeric contact surface of a contact element made from an elastomeric material in a workholder;
- simultaneously placing said outer diameter against an elastomeric support ring of said workholder;
- placing an elastomeric biasing member adjacent said inner diameter of said workpiece;
- and
- imposing a locking force on said elastomeric biasing member whereby said resilient biasing member deforms to generate a locking force component in a direction away from said contact surface and a locking force component in a direction transverse to said central axis whereby said locking force holds said workpiece for machining thereof.
