  • Machining Square in 6 jaw

    Hi Everyone,

    Here’s a little trick I have been doing for so long it has become second nature. That’s why I didn’t think of it until I was doing it again recently.

    If you have a 6 jaw scroll chuck and need to machine something in/on the center of an end, you can hold 2 opposing jaws back as you are putting them in and engage them the next time the scroll comes around.

    Now you have a simple accurate way of centering your square stock.

    I first did this by leaving 2 jaws out completely, but the open slots attracted chips.

    Best wishes to ya’ll.

        Yes, good idea and thanks for posting. Could also take off two top jaws if you got em.

          hmmm could also pad the four jaws that contact, and not mess up the other jaws positions.

          well maybe...
          would depend on if the padding could be tall enough that the two jaw clear the corners
          and short enough not to bump into its neighbor

          maybe two short sections of "angle" material on opposite corners of the square stock corners
          just under the jaws.

          maybe not the best verbal description, squawk if it does not make sense
