| 183 | Runout eliminating collet chuck | US11001987 | 2004-12-01 | US20060115337A1 | 2006-06-01 | Fusao Higashi |
| A precision collet chuck assembly of the type where the shank of a tool is mounted in a bore in a split collet and a clamping nut squeezes the split collar into a gripping association with the shank of the tool. At least three radially adjustable set screws are positioned so as to bear against a rotating tool at a location axially beyond the collet and between the tip of the tool and the shank of the tool. These set screws are individually and selectively adjustable to bring the tip of the tool into a desired position relative to the axis of rotation of the assembly. The extent of the adjustment is generally limited to less than about 0.002 inches. The radially adjustable set screws can be mounted in a centering collar portion of the clamping nut or in a separate centering collar. The adjusting set screws can be mounted with their longitudinal axes defining a common plane or one or more cones with the tips of the cones on the rotational axis of the assembly. Being in direct engagement with the tool causes the adjusting set screws to be exposed to considerable shock and vibration. This may cause them to move out of radial adjustment. Locking set screws are provided for locking engagement with the adjusting set screws to hold the adjusting set screws in the desired radial positions. | ||||||

| The center of a collet having a plurality of individual gripper members resiliently spaced apart in an annular array and operated on by a frustoconical surface can be adjusted by displacing some of the gripper members more than others of the gripper members parallel to the axis with which both the annular array and the frustoconical surface are nominally concentric. This causes the frustoconical surface to produce greater radial displacement of some of the gripper members, thereby shifting the center of the collet transverse to the above-mentioned axis. An element transversely moveable relative to the axis causes displacement of some of the gripper members more than others. | ||||||
