Re: 4 Jaw chuck to fit EMCO CNC5

Alison and Jim Gregg. <ajgregg@...>


The EMCO 5CNC  does not have a threaded spindle nose, but uses an oddball DIN fitting where a recess in the chuck backplate pushes onto the spindle nose to locate it concentrically, and is held in by either 3 or 4 screws - (3 or 4 jaw chuck), through the front of the chuck into the end of the spindle. 

It's a good arrangement in that the chuck cannot unscrew itself, but is a bit harder to find, especially generic ones - been there done that!
