I understand the basic concept of a power drawbar - the device pulls the collet into the head and keeps tension on the threaded rod until whatever tool that is connected to the head needs to be changed. I can also understand a device like a solenoid compressing washers creating space for the collet or tool to be removed from the head or a piston pushing or pulling the top nut drawing the collet into the mill head. What I don't understand is how does the collet slip off of the drawbar and another tool re-mounted. My mill has an R8 taper drawbar - I believe it is 7/16"; that a nut screws down on a threaded rod that travels thru the mill head connecting the collet or tool. How does the tools or collets slip off of the threaded rod without turning or unscrewing? They seem just to fall out, and a replacement is held some way and reconnected.
Can someone send me a picture of how the collet is held to the threaded rod or explain in simple terms how the collet is held by the drawbar without screwing the drawbar into the nut on top and the collet in the tool head. Thanks for your time.
