I want to post how I installed ball screws in the X-1 micro mill but I'm not quite ready so I've got something here that I hope will be of interest. Also, I'm having a lot of problems posting pictures here from "Photo-Bucket", they seem to have changed things sense the last time I used the. I think I have it figured now out so here goes.
A year ago or so came up with a Quick Change Tooling system for the X-1 micro mill. See below photo:
I used the Tormach type of holders but using a .500 collet instead of the .750 they use. Here are a couple of drawings of the rig:
With this setup I needed to adjust the draw bar top length so it meets properly with the cam lever. That meant I needed to adjust the collet while it was in the spindle so I used an old computer case part but it didn't work very well:
I decided to make a M-2 collet wench, similar to the ones I see for 5c collets.
More to come:
