Finally I finished it , I must have like one million hours into it , sure feels like it. so let me explain to start I used a flat ground lathe bed to mount the main rails. I have found in the past this is a big problem the ''flex'' factor . I machined and keyed everything and over built everything. next I built a tilt table to level the cue out , its set up when all the way up and down its dead on. the table runs only .001 all the way down top and side. I ran an indicator on everything head stock , tail stock , x and z axis all have 0 run out , I'm a mad man. I used anti-backlash ball lead screws, also pined the head stock and tail stock under neath with tight fitting delrin bushing . the next thing to make is is inlay table and a fourth axis in the future. enjoy pics D Hill

What a beast!
Looks like a 20MM ball screw.
I have a THK actuator with the same ballscrew I used for a cnc taperer for a while. The beast can run and has way beyond torgue we will ever need. But, the sucker is smooth as butter .

Very well thought out machine. Nice to see someone put the time and thought into a project. I especially like the tilt feature. Bet 50% of the people wouldn't have thought of that. When you going to cnc the indexer.

I'm a little under the weather when it comes to running cnc ,so a 4 axis is like throwing a wrench in my way. all in good time. D Hill
 
Darrin,

What a great piece of machinery! As others have noted, there must be as many hours in the design as there are in the build. The end result proves that.

I bet your 8020 dealer likes you!! :)

Speaking of 8020, do you find it straight enough (disregarding flex) or do you have to mill it even flatter/straighter to meet those tolerances?

My machine is coming along, but it's nothing as grand as yours.

Hopefully we'll be able to see a video of it in action one of these days, too.

Again, very nice, VERY nice!

Nice

So can I ask how much you spent in materials? Did you ebay the screws and slides? With all said and done how much did you save from just buying an equivelant cnc gantry? Just curious because I have been considering starting a build on a machine for inlay and tapers.
 
Very nice.

PS: Next time you need your Allen wrench, it's stuck in your tailstock.....

Gary, you asked a good question. let me just say today's aluminum is so bad twisted , warped , ect . I had to fly cut and square everything up. on the other hand 8020 stuff runs with in + or - .003 super good in my book. thanks D Hill

Prepare your self you will spend a lot , nothings cheep now a days . I buy aluminum through Enco and shop around for everything else . to do it right you will spend 2500.00-3500.00 just on materials this may include motors and controller . time , time , time in machining is out of the roof , I estimated 3500.00 plus in machining time then theirs software , a computer , milling bits ,4 axis tail stock ect.... Good Luck D Hill
