Q: is there a recomended or perfered small milling machine (i.e. micro-mark milling machine) that also has the stepping motors capability and maybe even cnc programable.

Mike
I like working with mills and lathes but I am not in the same league as Paul.  I'm interested in finding a small CNC mill and lathe as well.  I haven't found anything I like all that well.  These days, some of the larger machines can be purchased used at very cheap prices. I wish I had some place to set one up.  For the most part, I do a fair amount of mechanical design for my job and I have very good relationships with a few shops.  I help them out with problems from time to time and they let me use their machines in a pinch.

Mike:

Yes you can pick up CNC machines at good prices, but most often the reason they're priced low is the software is out-of-date and likely partially or wholly incompatible with contemporary applications. I'd recommend dealing only with a reputable dealer so you don't end up with essentially a lemon. Having a good relationship with a local machine shop is certainly a plus.

Hauk:

For the bolts in the post, I used a 1.0mm die chucked in the lathe. I ran the stock through twice, the first time to start the thread, the die just made a light cut since the phosphor bronze wire was slightly undersize for 1.0mm threads. The second time I clamped the die more firmly in the chuck closing it up slightly and ran the stock through again, creating the threads. Obviously they're not absolutely accurate, but still work. Elsewhere on this forum, someone posted a photo of a clockmakers miniature tap and die set which I shamefully admit I covet.  I've been looking for one of those for years but have not been able to find one at an affordable price. High-quality miniature taps and dies are available from J. I. Morris Co. http://www.jimorrisco.com/ in numbered and metric sizes, but are very expensive, i.e. a single .30mm tap is $120.00  Shocked
