Jacobs Taper Magic Chucks


Magic Chuck Instructional Aid

All Magic chucks have a collar on its diameter that needs to be slid back toward the spindle to eject the tool and magic chuck collet. The next tool to be inserted in the chuck may have to be rotated to align the locking ball mechanism. When the outside diameter collar is released, the magic chuck will lock in place. In our catalog we recommend the spindle not be running during the tool change. Collis recommends if you choose to not stop the spindle to change tools, that you engineer the job for the proper spindle speed and guarding that would protect the machine operator.

The safest method to change tools is to stop the machine operation.
