  • Attachment for automating milling machines
    Patent number: 3955267
    Abstract: An improved portable bracket assembly capable of being attached to a milling machine to thereby allow a plurality of sequentially located tool holders to be selected and inserted into the spindle of the milling machine. A special camming device containing a plurality of settable cams, one for each tool holder, and synchronized with the movement of said tool holders, controls selected switches. The presettable cams allow the first switch to continuously engage the indexing means driving the tool holders should a tool holder not contain a cutting tool. The resettable cams also control a second switch mechanism for creating a specific tool speed control signal for the specific tool in each tool holder.

  • Removable attachment for automating milling machines
    Patent number: 3951273
    Abstract: A portable bracket assembly capable of being attached to the spindle carriage of a milling machine. A self-contained indexing table and indexing means is located on the assembly together with a transfer arm having three degrees of freedom and articulated fingers for selecting a tool holder from the indexing table and inserting the selected tool holder into the spindle of the milling machine when operated in a first direction and reversing the sequence when operated in the opposite direction. The assembly attachment allows a numerical controlled milling machine to perform sequential operations on a work piece that requires the use of a plurality of different individual tools.
