Did you check the fuses? look at the little green ones, see if there is a white flag in any. Maybe something in the machine is not locked and ready. Check any turrets if it has them. I don’t know a...

I’m in search of a master board for a 3t-a control. This is on a 1981 citizens F12. Is there anybody out there who repairs them of has remanufactured ones or even better a good used one. Old parts...

You use the G50 to set your starting coordinates. A OT should return the axis to their home positions at start up, you may need a G30 to do this or a G28. Once homed you use the G50 to set axis...

I have a old Citizens F-16/3T-C control and it has a Servo Alarm #14 X axis. I switched everything from x-z and the problem stays with the x. Mother board has been tested by Fanuc and is ok. Any...

I'm lost on setting up offsets for the Y axis (sub spindle) on a Hanwha ML12 Fanuc 18i control, build in 2000. There is no offset page for this axis, manual says to us P-Code variables, but doesn't...

Have you tried stopping the spindle when the collet opens or at least slow it down. Sometimes at high speeds the spindle inertia will cause the fingers to put pressure on the collet and it doesn't...

You need to use TIN coated HSS drills, 135 point, if you are having hole size problems, I agree with boring, but if you want to save some money on tooling you can drill a smaller pilot hole and...

You do need a bar feeder and a tool setter to set up and operate this machine properly, and they need to be the right ones for an F-25. It most likely had a single hydraulic bar feed on it. If you...

What does the machine have with it. F machines require a tool setter, and what does it have for tooling, they require tool holders for both drills and turning tools. What kind of bar feeder does it...

Thanks MCImes, we have the same thoughts on the multispindles, but we don't see the big quantities needed to set one of them up. Our shop rate is lower than everything I've read so far. I think a...

What's the going rate per hour for cnc swiss machining?
I ask this because once in a while we get a response from some of our customers that they can buy the part for half of our quoted price, and...

Ned-dragon's got it right. It's a coordinates shift setting and can be used many ways to simplify programing. But it's most important use is setting your x and z axis starting positions. When the...

Here's what you need to do, without the toolsetter it's a little tricky. To set up turning tools all you need to do is put in a known dia. stock, say .250 using the MDI move the x axis to that dia....

From my experience threading long shafts like part 1 can be a problem. It will work ok as long as the major diameter of the thread is the same size as the bushing. If not once you retract the...

As for the toolsetter usually you get them with the machine. I'm not sure it the F25 has it's own or if any F machine toolsetter will work. For the chuck the swiss uses a collet and guide bushing,...

The F machines are very good, but slow. If you are doing short runs where speed isn't important you'll be ok. If the machine you are looking at has Fanuc controls it should be good. Parts are...

Guys it's your lucky day, I have been programing and setting up F machines for 16 years, we have 6 on line that we use everyday. By what i've read you guys are a bit lost, so I'll do what I can to...

What control does it have, I have several f-12's and f-16's with Famuc 3tc's and usually when a problem is intermittent like that it's a circuit board issue. If you have another machine to swap...

This thing has a mind of it's own, you get one glitch worked out and something else starts acting up. Now it keeps stopping after it pulls the remnant out of the pusher and checks to see if it's gone...

Thanks Maz,
We have it worked out, it would take 3 pages to explain all we went through to get it working, and it still doesn't consistantly reload. We have had the techs out twice and they just...

We have put together a Hanwah ML12 and Iemca Genius 112 bar feeder, we are looking for a schematic for the interface cable, anybody out there with this combination? This thing is giving us fits,...

Thank You!

I'm not familiar with the pull up resistors, what do they look like and what should I look for.

I should have a new switch early next week, we'll see if it works.

I'm not sure if this is the right place to ask this question, but on a Fanuc control what does the 0V side do, it's usually tied in with the 24V. I have been having problems with a turret count...

We use a simple DNC windows based program from Refresh Your Memory, we bought a lap top and made a cable to go from a usb port to the RS-232, this was the trickiest part. The enitire package with a...

Rob,
I don't have any experience with the 10t, but on the 3t's if the parameters are lost I have to jumper the e-stop button and put in parameters 1 to 4 and all of a sudden the machine comes to...

Hi Rob, Maybe I can help.
Is this the same machine that you bought and it wouldn't run, posted around 9-15-10?

I'm not tech but I do have several years working on F-12's and F-16's with 3T Fanuc...
