| 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. | ||||||

| PROBLEM TO BE SOLVED: To prevent the rotation of an inclined table exceeding an allowable rotation range in the case of the emergency shut-down of a power source such as a power failure. SOLUTION: In this inclined table indexing device 1 wherein a rotary member for a table or the like is rotated within the normal range of a rotational angle previously prescribed by a direct drive type motor to incline the table to keep the inclined table retained by the operation of a holding mechanism, an elastic displacement member 11 having a passive pressure surface 12 is provided at one of the rotary member and a frame 6 of the inclined table indexing device 1 and an engaging part 13 contacting with the passive pressure surface 12 at the other. When a rotating spindle 5 reaches the outside of the normal range of the rotational angle accompanied by the free rotation of the rotary member in an emergency case, the kinematic energy of the rotary member is absorbed by the elastic displacement member 11 to stop the rotary member before reaching a dangerous angle range.
