You appear to be quite confident. Have you seen this condition before? It doesn't appear to be the video card. That was replaced today and the result did not change.

How can you tell?



How can you tell that?



Visually? I did take stuff apart and inspected all the connections and found them to be solid. I think it is possible the problem is...

This 1995 VF3 has a video problem (see pic below). We tried a new monitor and the same problem. We are thinking the video card is the problem. Anybody seen this particular problem? We were able to...

I've been thinking about buying a used mill and lathe for my basement. I work for a major manufacturer of metal cutting machines and would love to use / tinker with them in my spare time. One thing...

I'm in a Makino Pro 5 control PMC 1 trying to figure out where a ladder element is getting controlled from. The address is Exxxx. From the manual, the E addresses are "extra registers." But how do...

yes, it was a check valve integrated into the cylinder assembly that was dumping pressure to tank during the high pressure phase of the press. There was a broken spring in the check valve.

I'm not sure pen magnets would come up on a craigslist search. But! I'm pretty sure nobody else even sells the wonderful electric fly swatters. Too bad. You'll never get your hands on one of them if...

At best, I'm a sort of shadetree machinest. Yet, I find the topic interesting due to the San Diego CNC comments. I have learned at least one thing in my career. That is, appearance and impressions...

At that rpm I would agree balance is a non-issue.



If it were an application such as a HMC spindle, I would still cringe because the grub screw might be of some different weight. Yet, it would...

Is that because of there being a substantial reason for not modifying the shaft?

At my work, we manufacture rotors that go in superchargers. They drill small dimples into the lobes of the rotors...

Unless your talking about some high rpm application, I would think drilling dimples into the shaft would suffice for set screws. I didn't see what exactly you're thinking about doing it on...

The inside one is typically the home and it's right near the tool change location (y axis in a horizontal mill perhaps?). You should be able to go to the i/o screen and watch the switches turn...

As for as the repeat failures, when I've done a spindle repair I had multiple people warn me to check the coolant lines for bad o-rings & such that might be allowing some coolant out onto the spindle...

I just realized I never mentioned that there was a failure. It was some number (23 maybe) that would show up on the screen and drive that indicated rpm's were >50 off from the reference. New assembly...

Got everything out

When we removed the rotor/spindle assembly, we noticed radial gouge tracks on the rotor surface as if something got in there and got ground up as the rotor spun. The rotor...

I should've explained it better. The spindle spins freely by hand. When I spin it by hand, it shows rpms on the drive and on the operator screen just fine. A good hand spin gets it up to 40-50 and...

The spindle will not rotate at all. We can freely rotate the spindle by hand and see right rpm's. We have determined conclusively that the drive is good by swapping with another identical machine....

We've got hydraulics in all our CNC equip where I work. Also, I have other equip that has hydraulics, but can't be categorized into any other forum (press). Why not have a forum dedicated to...

Just read through your thread. Wow. Awesome stuff. Bummer about the ball screw. I really have a hard time understanding how a ball came out of the channel to ride up on the OD of the BS. I need that...

After further consideration, I think a simple NC relay in the output path is sufficient because there are other contacts in the new curtain control that can be put in the path of the signal that...

Yes, I tested the Banner. It closes the contacts when the curtain is "clear."

I thought about adding the relay. While it doesn't seem possible that a simple NC relay could weld open, wouldn't...

The Sunx doesn't provide the voltage, it only passes it back to the machine control. It is opposite from what you're thinking. The Sunx output relay is NC and opens the path when the curtain reports...

We have a Mazak FH4800 that has a load area safety curtain system made by Sunx. We are looking into retrofitting the SunX curtain system with a Banner USCD 1T2 style due to having an abundance of...
