+1 for Maritool. The maritool 1/2in. hotmills for dry milling steel are a new favorite of mine.

Its probably fine but it's hard to tell with out being there. Bad spindles are generally pretty loud and you might even hear the bearing race rattling around. Fadal spindles run 3kish and they're...

Good buy on your part. Welcome to the club. Fadals are lambasted as they're compared against newer production machining centers but they're great for the real onesy twosy work shop actually get and...

On a DC Fadal resolvers with bad bearings or some other issue I still can't comprehend can cause jerky motion. I've had loose wires to the tach also create such a scenario and its always a good idea...

Yea. Its also worth mentioning that even with DC fadals, rapid speeds increased as the years went on. My older Fadals are slow enough VMC40, VMC15xt, ect that they tend to live on 100% rapids. My...

You got me. Every fadal I've seen, 30 tool umbrella changes included have a Geneva wheel indexer so incremental movement of the carousel is a guaranteed thing. It would take to a servo drive setup...

I pulled what was I guess the servo coolant board from slot 13 and restarted the cnc to find it open up with a memory error at 63FF and a prompt to zero memory and view diagnostics. Unfortunately,...

Thanks for the suggestion but unfortunately it didn't change anything.



I have a 96 4020 with DC servos at my disposal. Are any of the control boards, keyboard interface, ect interchangeable? ...

I recently purchased a 97 4020, our first AC servo machine and I've been unable to boot up and run the machine.

Upon power up the machine either opens up the startup screen or sometimes it loads...

P13 is for the emergency shut off when the doors are open ect. Lots of people disconnect this and there was a court case about how easy it is to disable Fadal's safety system.....

My 94 VMC 15...

That sucks. Sorry for your ordeal. I have a 94 and a 97 vmc 15xt if you have any questions. The two machines are surprisingly different.

I run Calmotion flash drive/ dnc conversions on all of my Fadals. They're $500 and they pretty much eliminate all of the issues associated with stringing lengths of RS232 cables about the shop. ...

Do the hot HSM chips burn the wood floor?

I just picked up a 97 vmc 15xt as well but its pretty much a cream puff save for a rough spindle. I have no intention of replacing any of my oil lines. On my solid way machines the oil restrictors...

I rebuilt a spindle that was contaminated in a flood on a vmc15 not too long ago and so far its working fine. I used about 3-400 bucks worth of dead stock matched pair angular contact bearings...

What kind of drive? I have a VMC 40 with a a Freqol 700 retrofitted to it now. Its been a while since I installed it and the conversion was a bear at the time but if you give me more info I can...

Is the power supply energized? I believe the machine needs to see the proper conditions emerging from the power supply to power up the boards and ultimately the drives.

I'm rebuilding a VMC 40 at the moment so I might be able to help. Email me at munzmachine at y a h o o doot com. My current electrical gremlin is having to jumper j14 to j16 if I remember right. ...

They'll be another one. Yes, great point about sliding machines on chunks of UHMW plastic. If anyone needs any I have tons of the stuff, literally lying around the shop and its indispensable for...

I am on the board of a high school situated in University City that is creating a niche program in which High School students are educated in an engineering intensive environment .

Two "Part...

Yikes. That's pretty impressive. I'm very seriously considering a similar conversion to at least one of the Fadals lying around my shop. Did you ever manage to get full functionality out of the...

My uncle in the elevator business tells me thyssenkrupp has a surefire method of being the top home elevator company here in the us. They write a check, too bad it just lasts three weeks.

It makes me sick to read this. You have been an asset to Fadal and everyone who views this forum since well before I ever dreamed of owning a cnc. Mag certainly is finishing up where the Germans...

I'd run hot rolled steel instead of cold rolled. It has less internal stresses and tends to be a bit more stable. After welding, its probably a good idea to stress relieve the weldment via some...

So the 5th axis plug is giving signals more complex than a simple pulse to go? Thanks. Dave

Pardon my ignorance. Are these programmable rotary tables basically akin to electronic dividing tables that receive limited inputs, ie a single pulse telling it only to index to the next programmed...

I'll throw in my two cents. I got a 96 Fadal 4020 and a 97 Daewoo Puma 8S lathe as my first two cncs ever. For all the knocking Fadals you hear I'm certainly more than pleased with it. It did...

Haha, You mean real people actually made these machines. Someday someone will sit in awe as I tell them the horror of how concert pianos were made. Thanks for the info.

No Mitsubishi Melda 520L so I guess you're out of luck.

Probably not relevant to your scenario but a couple weeks ago I had an apparent resolver failure that turned out to just be loose wires. Surprised the hell out of me.
