Abstract
A method and system for holding fast a workpiece using three or more jaws that are mounted on a chuck base. The chuck base includes corresponding jaw guides, which constrain the movement of a respective jaw toward the center of the workpiece. The jaws collectively move toward the center of the workpiece by tightening a gear that engages was each jaw and is included in the chuck base. Each of said jaws includes 1 or 2 two convex contact regions.
Claims22
A method for holding fast a work-piece having a perimeter that includes a curved portion:
- imparting upon the perimeter a minimum of three forces substantially coincident with a plane that is substantially parallel with a primary work surface included in the work-piece;
- and
- increasing the magnitude of said forces in a substantially equal manner when a tightening gear is engaged.
A system for machining a work-piece comprising:
- chuck base that includes three or more jaw guides;
- three or more jaws each disposed in a corresponding jaw guide, wherein each jaw includes a first substantially convex contact region;
- and
- chuck tightening gear that, when engaged, causes each jaw to move toward a center point along an axis substantially parallel with a primary work surface included in the work-piece.
A wheel that includes a perimeter and is manufactured according to a process that includes:
- imparting upon the perimeter a minimum of three forces substantially coincident with a plane that is substantially parallel with a primary work surface included in the wheel;
- and
- increasing the magnitude of said forces in a substantially equal manner when a tightening gear is engaged.
