Pretty slow. For general machining you figgure 500-650 sfm which translates into 53-70 rpm on a 36" dia. piece.

My pleasure.
I saw a pic of a lathe, that had a seat attached to the compound and the operator goes along for a ride.BiG_JoN said:

I saw that too. He was making a canon.
God forbid it that thing crashed.

I've been lurking here for a few weeks & finally registered. This thread caught my eye so I thought I'd show you the CNC setup I use. Maybe this will give you some ideas.

I gotta have one of them CNC auto-cue building orifices for my machine..... that must be the nuts. 
I have to say that I am it total agreement with you on your CNC philosophy. I have been saying for years that its just another tool.
Are you using the techno software for that, or have you gone to a better controller/software package?

I used to do everything with the "approved" pantograph but my tendonitis forced me to upgrade. CNC never complains.
I use the Techno software to run the controller...not sure if I have an option in that respect. I mean, it's their hardware...isn't their software required to interface with it? Please tell me if I've been mistaken but I don't think I am.
As for my G-code, I originally used CADLink (actually a very nice, user friendly program that I got with the Techno package) to generate the programs but my Techno rep deserted me when I shopped elsewhere. Not a problem as I found another Techno rep who doesn't rely on me as his sole source of income
Let me clarify here that Techno has been wonderful. I have nothing but praise for their products. In over 10 years the only problems I've had are a limit switch I damaged when I rapid traversed against it (it did it's job, though). And the rocker switch on the controller died. Total cost for replacement parts came to maybe $30. Other than that, I've grown to trust its accuracy enough that I program my inlays to size with .000 offset & the pockets with .0015 offset. Due to cutter deflection, the actual clearance comes out to <.001 per side. Consistently. Can't ask for much more than that. For the sake of comparison, when I use the Makita or Porter Cable routers, the same .0015 offset might or might not work due to looser bearings. Sometimes there is more clearance...sometimes the inlay won't fit. And subsequent cuts run the risk of going oversize due to the "freewheeling" cutter.
Then I tried BobCAD but they hosed me on a package deal. And, no, I won't go into it.
I now use AutoCAD for design (not necessary but I'm using it just to learn it) and MasterCam to generate my programs. Kind of overkill but I'm familiar with MC from my real job so the transition was easy.

Makes a finished cue in fifteen minutes?dzcues said:
That is the machine at the top of my wish list.
By the way, Bob, you are the only one here,
who has made a cue I have tried. It was a sneaky
pete, very nice.

You got a cool set up there.
What kinda spindle you got there on your Z? Doesn'y look like porter or makitafrom my view... and where could you get those cutelittle talstocks and indexers?
Thanks,
Hadj
Correct Me If I'm wrong, but the tailstock looks like a sherline, and altough the indexers in the picture look of better quality, I have a import that looks alot like them. Greg

I have a friend that built a cnc, and used Techno. He had a lot of problems with the software, but almost all were centered on the A-axis, which you don't seem to have.
He switched to FlashCut, and was very pleased with the results. However, he had to replace the controller to do it. (you're NOT mistaken)
He likes the hardware though, as you do. They make great stuff.

Not sure what brand the spindle is. No markings at all inside or out. Techno rep (greedy one) wouldn't tell me what brand, only said it was German & cost $300. I'm on my 3rd one now but I found someone who rebuilds them for $100 (notice the alignment markings on the case) so I should be set for life. You can buy them through Techno. If you're interested, I'll send you the (good) rep's email address.
Tailstocks are Sherline & one indexer is Phase II's good model (they make two) and the other indexer has no name. I got it at a machine shop auction for $15.
And to Sheldon: never got into the 4th axis stuff. I'd guess that's where his problems lie. I have NEVER had a problem. I started with the 1st generation software with a HUGE card in an old 386 tower but the old style hard drives are getting harder to replace so I upgraded to the new PCI card w/new software & interface. They both work fine & new interface is clearer & more versatile. I still have the old computer, controller card & software if anyone is interested. The hard drive died & it was the 4th one in about 2 years. Don't forget, this was 1993 technology & times, they are a'changin'. New hard drives aren't compatible with the old setup.
