Claims

[Scope of claim for utility model registration] The above-mentioned NC performed when determining the position of the machined part of a workpiece placed on the bed of an NC machine tool.
A holder to which a probe used to set the initial position for coordinate counting using the spindle axis of a machine tool and a micrometer that indicates the amount of displacement of this probe can be integrally attached, and this holder can be rotated at one end in the axial direction. support,
a shank whose other end in the axial direction is integrated with the spindle shaft of the NC machine tool; the rotation center of the holder is provided offset from the rotation center of the shank; A processing part center position indexing device characterized in that the positional relationship of the probe with respect to the processing part is changed.
