Abstract: A rotary table for a material processing machine such as a vertical milling machine utilizes direct drive motor(s) to precisely angularly position a work piece along one or more pivotal axes. The direct drive motor(s) are thermally insulated from the remainder of the machine to limit misaligning thermal expansion of the components of the machine. The motors may be symmetrically attached to their respective supports such that thermal expansion/contraction of the motor and surrounding components occurs symmetrically with respect to the motor to limit misalignment of the motor's rotational axis. A motor may mount to its respective support only at a first axial end thereof such that thermal expansion of a second axial end of the motor does not adversely shift the position of the first end. Axially narrow clamps selectively secure the rotors of the motors in desired positions.

Abstract: A workholding assembly (10) for releasably holding a work piece includes a master variable-volume fluid chamber (150, 830) disposed between a machine and the machine's axially- movable draw bar (110) such that the workholding assembly converts the mechanical axial force/movement of the draw bar (110) into fluid pressure/fluid flow. The resulting fluid pressure operates a fluid-driven gripping assembly such as a radial-piston-based hydraulic collet assembly (20, 500) or a diaphragm-based hydraulic gripping assembly (800) . The hydraulic collet assembly may be a quick-change assembly that enables an operator to quickly and easily change between differently sized or shaped collets .

Abstract: A bushing (50) has an externally threaded portion (52) with a thread pitch P 1 . A collet body (20) has an internally threaded portion (31) with a thread pitch P 2 , which is smaller than P1 by a pitch differential, ?P. To assembly the bushing (50) and collet body (20), the collet body is heated relative to the bushing to reduce the ?P. The threaded portions (52, 31) of the bushing and collet body are then threadingly engaged with each other. The temperature of the bushing (50) and collet body (20) are then equalized, which tends to increase the ?P, which causes the threaded portions (52, 31) to bind with each other and resist relative loosening rotation. The threaded portions (52, 31) may additionally/alternatively be reverse tapered and/or include variable thread pitches that cause the threaded portions to further bind with each other.
