Does anyone know of a company that rebuilds (re-true/re-square) small rotary tables? We have a Sankyo RT100 (A/C axes) that has been crashed and is A is no longer square to C. We have shipped one over the pond before but the price was almost as much as a new rotary... any suggestions? Thanks, Jon

On our Mazak VCUs, it will do the same if the back feed is over 200ipm. Has to do with the smoothing parameters. We can take the exact same code and run it on a Mazak Compact or a Robodrill and it wont happen.
-
So what three points are you taking? Ive tried to get Methods to help us setup these parameters on a robodrill with basically no help at all.
-
I do this fairly regularly... I'd try to slow the sfm to around 100-150 and .0001-.0002" per flute feed.
-
Yep. Good path even if you lock it to 3 axis. Good collision control and lead in/out as well
-
I ended up using morph. Thanks Ron, that got me almost exactly what I was looking for. Here's what I came up with: https://www.dropbox.com/s/ctf4ryhz8bvqi0h/MORPH.ZIP?dl=0 Let me know what you think.

I actually started out using a 1/8" lollipop but I kept breaking them. I swapped to a 1/16 Mitsubishi ball nose and it seems to be more rigid but I cant quite get it how I like it. I think I see what you a saying about the .005" square as the "morph to" chain, but I cannot think of a good shape to use as a "morph from" chain...if that makes any sense. I will poke around with the roughing page, never thought of that! There are so many new parameters and lingo when you go beyond a simple 5 axis curve, just gotta figure them out one at a time!
-
Ok here is something closer to what i was talking about. I was too worried about stripping the model down. Notice it takes a large stepdown after about 20 passes... any way to smooth that out? Ron, not sure what you mean by driving through a point for morph between two curves. You mean using "to point" for tool axis control? Would morph be able to handle all of the inside undercut surfaces in one toolpath? Thanks, Jon MORPH.ZIP
-
I had to strip the file down, so I just threw some parameter together real quick. Thanks Ron, I will give this a shot first thing in the morning!
-
This is the best I can do for now, I cannot share the actual file. Its on a Mazak VCN Compact with a small Sankyo rotary table. Let me know what other information you need. MORPH.ZIP
-
Yea, ill have to strip it down a little though.
-
In the attached file, I am trying to cut the green surfaces using a single multiaxis toolpath. Parallel and morph get me close, but the stepover is odd... Anyone care to show me a morph strategy to get some smooth motion? or even better, I single toolpath to finish the whole inside. That would be sweet! Thanks, Jon morph.X_T

You may need to turn off gouge check.

Scallop (constant-Z) with continuous ramping ability

Try decreasing your gap settings. -
Mazak variaxis i600 - g54.4
JMahon replied to cg077995's topic in Machining, Tools, Cutting & Probing
Did you ever get the sample code for the variaxis? I've been wanting to try this on our VCU. -
How do you use step files for holders?

Anyone have experience with an Integrex I-150? It's got a 2nd op vise/gripper rather than a sub spindle so the price should be quite a bit less than a full blown Integrex.

TR 160 TRUNION FIRST SETUP, NEED HELP WITH CENTER OF ROTATION
JMahon replied to MrRidings's topic in Industrial Forum
You should never touch the material and move z. Z height is set in mastercam. A good way to set G54 z is go to B90. A0. And face the stock at say z.250" Then rotated a180 and cut to z.250" again Now mic the tab you just milled. Should be .500" Now offset g54 z 1/2 of the difference of .500" and your part thickness -
I've been wondering about the lil 300a. We've got a vcu400a and some vcn compacts. Looks like the 300a is pretty much a small vcu with the same rotary as a compact. Id love to try one but the higher ups are about burned on Mazak now. Our service out here is not the greatest...
-
Haas is actually a decent machine. I've just recently gotten a chance to run them. I've always ran Mazak but for what I run on them, the Haas is just as capable. Haas service is top notch compared to Mazak.
-
Have not looked at tormach? Any specific model you recommend?
-
How do you like the tr160y trunnions? I've been eyeing that setup to put on a VF machine. A little off topic but has anyone used the new small trunnions Haas just came out with?
-
Also, who else makes sweet mill/turns like that Bumotec 191? All I really know of is Willemin and Chiron
-
No grinding needed. Just cutting metals and plastics. I forgot to mention, 5 axis is definitely a must. Would be for medical instruments and implants. Thanks for the input guys! Just wanting to see what else is out there. It's so easy to get stuck using what you know.
-
Whoa those bumotec machines are sweet! Any idea what one like that runs?
