Abstract

The figures show a toolholder by which optimal quality, polished, flat, curved or tapered surfaces can be produced without rigidly mounting the workpiece to the holder. Vertical and yaw motions are allowed, while a pitch motion is prevented.

Support Tool for Precision Polishing

The figures show a toolholder by which optimal quality, polished, flat, curved or tapered surfaces can be produced without rigidly mounting the workpiece to the holder. Vertical and yaw motions are allowed, while a pitch motion is prevented.

In Fig. 1, a cutaway section of a toolholder 1 is shown with a mounting tool 2 poised for insertion. A pivoted bearing plate 3 is spring- or piston-loaded (Fig. 2) for providing a force against the mounting tool 2. Pins 4, 5, 6 and 7 are secured to mating slots in the mounting tool 2 for contacting like pins 8 and 9 fastened to the toolholder 1, and pins 10 and 11 (shown in phantom) fastened to the bearing plate 3, respectively. A workpiece 12 is secured to the mounting tool 2 for contacting the polishing surface, such as the lap plate 13 (Fig. 2).

In Fig. 2, the mounting tool 2 is shown inserted in the toolholder 1, with the workpiece 12 contacting the lap plate 13. Wear pads 14 suspend the toolholder out of contact with the polishing surface. A spring 15 provides the force loading the bearing plate 3 against the mounting tool. A lapping force P or leveling forces P1 and P2 are applied to the mounting tool for the polish operation.

The pins affixed to the mounting tool tangentially contact the pins mounted to the toolholder and the bearing plate (Fig. 3). Pins 8 and 9 fastened to the toolholder in Fig. 1 contact the pins 4 and 5 fastened to the backside of the mounting tool (viewed from F...
