oil.....oil......OIL.....O I L everywhere

[AUminer]

Oil dripping out of the touchscreen, the power supply, all of the drivers, the electrical connections, the boards…oil in and on every single component in the cabinet, dripping into the toolbox below…all my tools and drawings, design files and paper notes are now oil sponges..

There is no way to clean this mess up, there will be oil dripping out of this machine constantly for months.

This machine is in a welding and fabrication shop…dust and dirt everywhere will soon stick to all the oil like a magnet.

Beyond tired of fixing this ..

Beyond frustrated…

I wish I had never purchased this machine in the first place, just one problem after another that I have to fix, re-engineer, modify and repair.

The Titan is a prototype machine, not a ready for production machine - it should not be sold in the current condition it is. Everyone who purchased this machine did not know it, but they are beta test subjects as an afterthought. It wasn’t anyone at Langmuir that placed a feature request topic in the Forum, it was us who added that, and not a single update or change has been acknowledged, implemented or offered.

I haven’t posted anything in months, because I basically gave up on trying to fix this machine - I bent up the parts I could and just outsourced everything since.

I had a rush job I needed to do, and now there is oil everywhere.

When I think of the name “TITAN” the submarine failure comes to mind.

If anyone wants to see firsthand where the oil comes from - just put your machine in manual mode and run the ram down all the way. Your machine will be covered in oil from the dump valves because there is no limit switch, no soft stops, no hard stops, no bumpers, no soft limit in the software at all…just a dump valve overload, which is two 1/4” high pressure lines, merged into a single Y fitting, then into an 1/8” ID fitting into the tank…combined 1/2” ID into 1/8” ID is a horrible design flaw.

A case of paper towels, a gallon of 90% rubbing alcohol, a quart of oil and 3 days of labor cleaning this pos is the last thing I should be having to do.

This machine needs to go away…and the oil isn’t even the reason

These two 1/4” HIGH PRESSURE lines…..cannot go into a TEE, then both feed into this 1/8” port and not have a problem

@AUminer

These two 1/4” HIGH PRESSURE lines

Are you talking the plastic lines? If so it cant be much pressure as barb fitting would never be used in a high pressure application would they?

Please tell me they are not using plastic lines and fittings in a high pressure situation?

I will say that is one big mess.

Mine has been leaking also, not like that but it leaks. Every time I look inside I just shake my head and say to myself lets do it another time.

[Knick]

So I went back and looked, which direction is the flow? from the valve to the plastic lines ?

if valve to plastic lines, then I could see them doing that. But if people are having trouble with the lines blowing off then I think a change would be made.

[langmuir-sam]

Wow! My condolences - I understand cleaning up a mess like that is a huge pain. Let me know if I can send anything to help you out.

It really looks like you managed to bottom out the machine hard. Ideally, those lines should never be blown or even used during normal operation, and especially not with that much force. Perhaps your PRVs need a little bit of a calibration increase so the machine properly stops before spewing out so much oil. Most pressure blow-offs have far far less oil coming out of them. I guess this is the equivalent of your car’s airbags making a mess when they are deployed. We don’t want the airbags to go off in the first place and the mess is better than the alternative.

In terms of design solutions, if you think that is likely to happen, then the full fix would just be to rout those lines outside of the machine into a big bottle. In operation a blow-off like this is very rare and I don’t get many comments from customers about it.

I get your point about the software and have taken the software feedback into consideration. We have just been implementing it with our fixes to Cutcontrol while we work on our other machines.

I am curious, what caused this? Was it a full bottoming out of the machine? Or an attempt at a high tonnage bend?

[langmuir-sam]

Those are pressure relief lines. There to mainly take a short spurt of oil from a pressure overflow in the rare cases where it happens. Usually they can handle it, but in severe cases they can fail to prevent the pressure spike from going directly into the tank.

If you know where your machine is dripping oil, send me a picture of the location and I can help you fix it. Usually the fix is pretty simple, like applying a bit of Teflon tape. Sometimes it requires a replacement hose connector.

[AUminer]

The plastic lines were not ‘supposed’ to be high pressure lines, but tell the pump that when it’s running full speed and the oil has no where else to go. zip ties on the ends aren’t going to withhold 1500 or whatever the PSI is on the pumps. It’s not supposed to happen, but in the real world, it does, and since there are no limits in the software - it’s going to blow the lines off 100% of the time when the ram reaches it’s end. I think there are only a dozen or so people who really use this machine…as in production or industrial use - the rest are hobby guys who make a few parts once in a while on the weekends for fun or small side jobs.

[Knick]

Yeah, I agree with you. This machine was never designed to be production or industrial not at this price point.

I did see a really nice press break at Fab tech it was about the same size as the Titan maybe 36 inches and 25 tons. Very well built very impressive. He said it used ball screws instead of hydraulics I believe.

Care to guess how much that was?

[Kwikfab]

How much, and what brand?

[Knick]

58k can’t remember the brand

Hello, this is mostly for Sam.
I have had the same problem with hoses blowing off when the safety valve popped because I clicked on the wrong lower die. It is messy and thick oil dripped out of the electrical cabinet for weeks.
This should never happen in a machine with load sensors and a computer. There should be a maximum software setting of 12.49 tons that when reached, a notice pops up on the screen saying, “software tonnage exceeded” and the upper leaf rises when the foot comes off the peddle. You went to all the cost to add sensors, use them.

Same goes for manual mode where you can set the max pressure. I use this for hemming the edges of metal where you want to press all the way down on a flat set of dies. I don’t want to set the hem to 2.693 inches. I want to smash it down. I want to set the pressure to 5 tons and when the ram reaches it the upper die goes back up, preferably automatically. Same with embossing leather.
Last, when I was setting the opening distance, I dropped the top leaf down to 4.000 inches and the machine loudly squealed and locked up. I had to shut it off, restart it and home it yet again. Why does a machine that can measure to 0.0001 inches not prevent hitting the limits? It should just stop, say “lower limit reached” on the screen and return to the upper set limit. Why does it have to Home again?
I really like the Titan, but it sure can be cumbersome.

[AUminer]

I entered the incorrect lower die once or twice also - since the dialog box only shows the first few letters of the options, it makes it difficult to select the correct one - another thing that should have been fixed before this machine was released for sale.

I also don’t understand why both the backguage and the main ram limit stops in the software were completely ignored in the program - even the extreme low dollar cnc routers and lasers all have limit stops in the software - there is no legitimate reason for 2 axis to just run wild and crash, especially since as you mentioned, the machine knows what position it is all all times, why install glass scale encoders and just skip 2 axis…it costs nothing extra except for 20 mins of code writing.

I agree with everything you said above, except the warning popups….there are already an extreme excess of those already in every single push of every single button…I think the max tonnage setting is in the bend program settings, as i’ve seen it several times when the program goes sideways and/or decides to put a material width all on it’s own.

agree with the auto retract - that should also be able to be selected in the IU - pedal down = ram down, pedal off= ram retracts. Every hyd press i’ve ever used does this - another simple feature that would make this machine great, but was skipped. Part of the reason I justified this purchase was to be able to straighten parts - but the way they neutered the software with all the inane safety forced button “ok “ - it would take two people to straighten a part - which actually is dangerous and a safety concern.

“cumbersome”…is an understatement.

[AUminer]

Sam, here is something you can do that would helpful : I think you have a machine sitting on the shop for testing correct? If you could post a video of the machine in manual mode, 15 ipm setting, with the punch and dies out of course - then run the ram down until it either stops or gives a warning - i’d like to see the screen - specifically both of the ram loading and tonnage graphs, also the sounds of the relief valves opening, if they stay open, how long they stay open, if they bleed off, how long it takes to bleed off, how long the pumps run, the screen warnings etc so I can compare that to what my machine is doing during the same operation ? I can gather a lot of data off what your machine does in comparison, and that might give some clues to what is going on with my machine. thanks in advance

[langmuir-sam]

I don’t want to bottom out the machine at our shop for testing - it has the old tank lid setup from before we did a design revision which will definitely cause a little mess, but I can message you some videos and information that I think will help you. I have a good video from another customer showing their live report screen during a bottom out situation. It definitely sounds like your PRVs are popping off too freely, too soon, and too long.

[Knick]

@langmuir-sam

but I can message you some videos and information

I would like to see that also

[autotech]

It’s a Unix system so seems someone could re write some code if they don’t want to step up to the plate. On the control Panel we were sketched out a bit that the Hydraulics were in the same panel Ours has not had a failure yet but ideally HYD would be better in a separate space under the controls. Still need to cut the stupid antler start button tubes super short to stubs to move them to the panel, can’t say how many times I run into them in the shop space the press sits. Ken in NC ~USA

[autotech]

Don’t stop AUminer, We haven’t started to do some of the fun stuff with this machine. That being said the software is the limiting factor it seems (unless doing some fancy work a rounds) for doing some special work as mentioned in other messages. Ken

[autotech]

Sam, that being said are you doing warranty upgrade since you found a design flaw? Please provide some details on early design vs later and maybe date codes on the “design change”?

[AUminer]

I purchased some high pressure plastic air line and fitted each relief hose into it’s own bulkhead in the tank, added some SS hose clamps and that seems to have solved the hoses blowing off.

The Y1 ram holds several tons of pressure on the screen reading, wouldn’t allow home, wouldn’t allow bleed, wouldn’t allow anything - nothing but error popup windows. shut down and reboot - same thing.

tried manually bleeding the ram pressure off - no change. The ram will move up and down in manual mode - but that is the only function that works.
