Abstract
A system for manufacturing lubricant supply grooves in a fluid bearing, in which a worn working body can be replaced. A through-hole is formed in the tool body so as to receive the working body, and a working portion is formed having a predetermined curvature at both ends of the working body. Both ends of the working body protrude to the same height from the outer circumferential surface of the tool body.
Claims5
A process of forming lubricant supply grooves in a member of a fluid bearing, comprising the steps of:
- inserting a working body into a through hole of a tool body so that working portions formed on opposite ends of said working body project from an outer surface of said tool body, said working portions corresponding in shape to the lubricant supply grooves;
- drawing said tool body through the member so as to plasticly deform portions of an inner surface of said member, due to contact with said working portions, to define said supply grooves.
A device for manufacturing lubricant supply grooves in a fluid bearing member, comprising:
- a tool body having a plurality of through holes formed therein, at least one of said through holes having a diameter which is different from another one of said through holes;
- and
- at least one working body inserted in a corresponding one of said through holes so that curved working portions formed on each end of said working body project from an outer surface of said tool body.
