Do you need a MACHINE operators manual, or a manual for the Fanuc control on them?

Do you need a MACHINE operators manual, or a manual for the Fanuc control on them?
Two very different things. If it's the Fanuc manual you need, it's not really an operator's manual, it's either a...
Split the difference, or thereabouts. It's really a tiny difference and swinging the head around you aren't going to see increments on the scale of anything tighter than 1º, many only show every 2º....
Both those metals are considered to be screw machine stock, so it's rolled into rounds. I've never seen it sold as plate so good luck.
Now why is it that you'd want either of those as apposed to...
BTW, if you would go to the Walter site and fire up the GPS application, follow the instructions I gave you and highlight the drill I recommended you can then click on the various tabs to get speeds,...
Depending upon how many holes you have to do, how much time you have, and how much budget you have you can use either a coated HSS-Co drill or a solid carbide non-coolant fed drill.
If you go to...
I would only plunge cut if it were me.
Picture #2.
Doing it the other way will your introduction to Mr. Chatter, and not in the most pleasant way.
Cost per part can only be determined when we know HOW MANY you have to do and over what period of time, and what machines do you have or would be willing to buy.
Coolant though spindle or not?
Also, you mention a cross hole. What is the configuration of this hole then? Does the Ø 3mm x 10mm hole cross through a hole of larger or smaller diameter, or is...
I don't know of anyplace to get manuals for specific machines, which normally cost hundreds of dollars. Is there any way that you could borrow them from your employer? These machines can take a high...
What insert shapes do you use? The best I've used so far is Walter Valenite grade 9605, in CNMG432-M4 for medium-to-light roughing cuts of .030" to .150" per side (.060 to .300 in diameter) at feeds...
I gotta say, I'm really surprised and confused about RLamb's experience with the ValCool products. I've met their Coolant Specialist, and he offered to test our water for free. We didn't actually...
We'd need a little more information to be able to help you. What material, hardness and diameter is that part?
You haven't really specified exactly what kind of modification you need to do. Are...
If you're doing thread rolling on a Citizen, you may soon find the limits of spindle torque on those machines. While it should be able to roll the 3/8-16 and perhaps the 1/2-13 and M10, the coarser...
The problem is probably related to the fact that the GTN/GTR/GTL series of inserts and blades are the biggest pieces of crap made with replaceable inserts.
Iscar came out with that design over 30...
Before you go off on tooling up for thread whirling or thread rolling, tell us more about the task at hand. The requirements of the job are paramount in the world of sliding headstock machines, as in...
Wish I could help, but all I can do is drool. ;)
When I worked for Norton Co. in 1987-1991, I ran one of those machines. It was a GP44N with the 1 meter length capacity and a swing-down I.D....
Walter makes a single-ended insert designed specifically for parting off aluminum. It looks nothing like the CF6, CF5 or CE4 shown in their video that was posted. Nor does it look like any other...
Well, you are correct that ignorance breeds contempt when it comes to controls, but I'm no dummy. Impatient yes, stupid no.
When I was thrown at the ECAS20 I had plenty of Fanuc experience and...
Sorry about that. You are correct in that I've mis-read the problem.
I agree with you Sir Denis, it does appear to be some sort of internal stress. That material is one that should be pre...
Ghyman,
You have a PM.
If "by hand" you mean using the dress press and feeding it by hand, you'll be good with a Ø.5000" straight shank HSS chucking reamer. Run it at half the speed and twice the speed of the drill. The...
There is no hard & fast formula. How much material to leave depends upon the type of material, hardness of it, the size and tolerance of the finished hole, and the reamer to be used.
When you say...
There doesn't seem to be a tooling problem so much as there's a mechanical issue.
I would look closely at three things. Start with how much out-of-round is in the raw stock, just how snug the...
One caution with that PDF:
DO NOT set passwords for that! If you do and somehow the password is forgotten, lost, or shipped out the door with the setup guy who just got binned, then the programs...
It's been over 4 years since I last programmed, setup or ran one of those, so forgive my probably ignorance.
It is not unusual for Star to have modified the basic G87 into something like a G287...
You've got a couple of correctable issues there. One, the inserts you are using may well be the wrong grade for a tough austenitic stainless steel like that. Looking it up on the painfully slow...
The link you posted does list most of the inserts that fit it. You just have to choose an insert size tolerance, top form geometry (chipbreaker or none), coating, grade and edge prep that matches the...
Wow, I've never seen nor heard of chromium plates like that.
It's just a guess, a starting point, but chromium being so abrasive I would start at 50sfm (around 1400rpm) with solid carbide and see...
It's highly unlikely that you have pure chromium sheet there. More likely it's either a high-chromium alloy steel or a piece of some kind of material that is chromium plated.
Is it shiny? Is it...
Wohlhaupter has those digital boring heads and they are nice. And expensive.
And worth it.
When you insist upon the best, that or the Walter-labeled version (exact same thing) is the way to go.
