If I make a small taper. ex W-200U0.05, metric.. I get some visual "rings" every 17th mm, I can feel them too, a straigth cut in z direction doesnt give me this kind of surface. Any ideas?

The steady rest is a hydralic selfcentering, quite powerful. I quess the smartest way to do this, is to clamp the stock the stock in chuck, and then use somkind of adjusteble collet with a center at...
If the stock arent straight the steady rest forces the 100mm bar into position, so if I clamp it with the steady rest and do my center, it will not be true to the chucked side of stock when...
I am using a big lathe.
How do I correctly center and machine long shafts? About 100mm dia and 2000mm long. I do have hydrualic steady reast. The material are a bit bent and have a various quality of surface before the...
Any one with a puma 400? Do you have problems with stability with the spindle when roughing? I cant take any big cuts during roughing, it makes the machine shake, alot. THe machine is almost new...
just set para 20 to 4 and press punch to save the current program to the card.
I am new to the machine, just started on a new job in Norway. My boss did say that the machine could monitor the load, but he had no idea how it worked. The machine is from 2006 and I think it got...
Is it possible to read spindle load to detect worn out tools?
Ive got a Puma 400 with Fanuc 21IT control. If there were a way to run a macro inte background of the nc it would be easy to do,...
yes, rapid on the way out, if the tool will leave a mark, it would leave the mark with g1 too, so then fix that problem instead.. TIR and so on..
mabe it does, checking it out on monday.
Is there a way to launch the livetool orient that the machine does before changing tool from a program, just like a spindelorient, but it is on the live tool? I know that it is possible to switch...
I always use a m-code to decide if there are chamfer or not at the end of thread, threads I make with P010060 makes a nice way out at the end even thou there shouldnt be any chamfer, mabe there are...
If you have the F10TA/F11TA you use P1 for one-side, constant cutting amount
P2 zigzag with constand cutting amount
p3 and p4 just like p1 and p2 but with constant cutting depth.
for the F0TA...
Sorry for hurting your feelings geof, Haas might be all that good as you say.
+/- 0.0005", it s twice the size of the tolerance I ve got on a couple of jobs, and I have no problem holding them...
yes, mabe they are alright.Depeends of what needs you got.
I must add that I never tried a haas. But it seems to be some low cost american junk, that is just the feeling I ve got about the brand, I might have it all wrong.
cant it be done with a mirror image on Z-axis?
it is leaking in the front, all oil must come down your tubing then, you prob got a oring that seals between the draw tube and the housing tube, so there will prob be plenty of oil when removing...
The fluid are comming from the cylinder at the end of the spindle, there are no fluid in a hydralic chuck. .. Remove the 3 big hex bolts at the chuck, then the chuck are mounted on the pipe that...
My daewoo can keep that dim, strange that we make jokes about the brand, but it is really much of a machine compared to what it costs.
I think you have to clear the memory while starting up, on Fanucs controls it is holding cancel+p during startup, haas prob have something like that too.. If the chuck were opened with automatic and...
OD tools/Right side cutting.
This macro works for Puma 300 with Fanuc 16/18/21iT (Tried it today)

I have only used it during automatic operation. And I drop the arm with a M code.. On fanuc I think I could be able to assaign a M code to execute a tool setting macro, called from Mdi.. Ex M110 T1...

Have tried it on a puma with Fanuc...It prob works the same with mits. On fanuc it is called automatic tool offset.. It could be used to check tool determine tool condition..
This is how it works...
I did mess up a live tool holder in the lathe, cost of $3600 and two of the jaws were nocket out, safety glass got a crack and the main spindle had to be aligned..the tool that collided were the tool...
there are stuff missing at start up of the interpolation, check the manual a bit closer and you will find it.
There were no need to cut entire pulley in waterjet, just the theeths, but the parts were machine in the lathe with a hand grinded tool to produce the tooth profile. It worked OK but it could have...
