Gday guys. Ive been chipping away at an ER40 collet chuck and nut. Im done with the chuck body, no dramas there. Ive decided that rather than buying a nut, I was gunna have a go at making one. Its all gone well so far, but Ive got one dimension I cant seem to find as part of the standards for the system. Most nuts come with a ring just behind the 30 taper that grabs the groove in the collet as the nut is opened, drawing the collet out of the 8 degree taper. I cant find the ID for that ring, so if anyone here has a store bought item, can you please measure the ring and let me know what its ID is?
Does it need the ring there? Does the collet wedge into that taper hard enough to require it? Obviously, not machining it at all would be the easy way to go.
If anyone is interested in saving some ground work on their own attempt at this sort of project, Ive got CAD drawings done of both components. Mine is being made to suit a hercus 260.
