Abstract
Disclosed is a guide member of a multiple spindle attachment employed in drilling and tapping machines, which guide member is adapted to guide a plurality of spindle holders that mount drills or taps, and comprises a guide member body fixed to a fitting flange of the multiple spindle attachment frame, a plurality of guide channels formed in the guide member body for guiding the spindle holders, and a disk-shaped positioning member for positioning each of the guided spindle holders. The guide member body is disposed such that its center is located on the central axis of the multiple spindle attachment frame when in the attached state, and each of the guide channels extend linearly outwardly in a radial direction about the center of the guide member body. The arrangement is such that the distances from the central axis of the multiple spindle attachment body to each of the drills or taps are set equally by abutting the inward end of each spindle holder against the outer peripheral surface of the positioning member which can be interchanged with another positioning member of a different diameter.
