I will take some pictures of the hardware I've made tomorrow. I need to start turning down the ballscrews ends and then I can really get the show rolling. Got my motor driver kit coming in monday (hopefully).
THe ballscrews you have may be ground, are they shiny looking? Also, do they have little grooves on the peaks? THis is an indication of rolled ballscrews. YOur ballnut may have been preloaded. I have nearly 25ft of 16mm ground ballscrew stock in my basement, but no nuts for it. Damn. Also, be careful when disassembling those ballnuts! There will be over 100 balls coming out, and can easily get lost.
I've found the X3 (as well as other Sieg products) to be very accurate where it matters. Nothing was deburred on this mill, I got my fair share of cuts when I was cleaning it. BUt all the components were a dowel fit, very nice. Using my screwless vise as a guide I checked for perpendicularity of the X and Y axes using my screwless vise as a reference. Well I got the vise square to the Y axis (over a 3" travel) to within .0001". Used my DTI to test this.
Then checked the X axis, not even .0001" of deviation. Spindel runout was under .0002"
Mill was trammed pretty well, not perfect. I will correct this before I get the CNC all up and running.
Also, its not that I am offended by using U, or "ur". But its distracting. I've found high quality forums tend not to have much of this.  |
