Haas taping problem

[Haassucks.com]

What would cause a 5/8" tap to go down and stop half way down taping a through hole, then after we have hit feed hold and reset, it is just sitting there. We open the door to figure out what were going to do to get it out (before I had bypassed the door lock) I get the tool to loosen the collet nut so we will be able to raise the z up and not ruin the part. Pull on the wrench and after I start pulling the spindle spins and bangs my hand with the wrench and throws it across the room then stops again? how dangerous is it when the spindle can spin with the door open and after the reset button was pressed?

I think you should read your manual. You hit Reset when a tapping cycle was active. I believe when this cycle is active the machine completes the cycle then responds to the Reset.

You should have pushed Estop before getting into the machine. This would have disabled all the drives. Your machine was simply stalled but under power and as soon as you loosened the collet it was able to complete the cycle and stop.

Incidentally if you have the 10,000rpm direct drive spindle, in other words no gearbox you were pushing it trying to drive a 5/8" tap. These machines do not have a lot of torque and it is easy to stall the spindle on taps larger than 1/2" especially NC threads. The way to tap larger sizes is Repeat Rigid Tapping and just peck in 2 threads at a time or less.

we have the 30hp 12,000 rpm spindle and haas tells us it will tap 1" just fine in steel.

I assumed the feed hold then pressing the reset would have made it not try to spin. Haas did tell me that was a flaw in the way the program works and that they are trying to fix it because they have heard of this happening before.

sometimes the e-stop does not stop it also, I have hit the e-stop when it was running and the screen was black and I kept hitting buttons trying to get it to stop including the e-stop then finally I just shut the power down to the machine to get it to stop. so next time I will probably just shut off the power to the machine.

You are so full of S**t. No, you can't interrupt a tapping cycle with a feed hold and you never will be able to. It will not stop until the cycle has finished and Haas will never change that, or ever say it is a problem.

Again, you are soooo full of S++T. I would love to be the lawyer who gets you on the stand for your law suit, if you even have one. God, probably the first time in my life I've wanted to be a lawyer.

You are nothing but a little sniveling cry baby. Sell those machine and get yourself another brand. I have seen and met people like you. I do not want to again.

Get a life and take responsibility for your own actions. You are one of those who wish to blame everyone else for what you do wrong.

The more you post here, the more you will show us just how ignorant you are.

I did not say the feed hold stopped the machine, learn how to read. the piece of **** machine stopped, i will repeat for the stupid people, the machine stopped itself not hitting the feed hold. and haas did say it was a problem that when the machine has stopped in a tapping cycle that at anytime it could take off again even if you hit feed hold, reset, and have the doors open.

if you bought a brand new machine and the first thing you tried to machine was a circle that was .625 and it made it an oval .007 out would you be mad?
not counting all the other problems...

It'd difficult to fully understand what happened in your case, but Geof's theory is one I would go with also. However, if it stalled then it shoud have kicked up an alarm along with it. My bet is Haas misunderstood your situation.

Feed hold does not stop a tapping cycle and Haas has written the software to prevent such action. It will finish the tap cycle then it will execute the feed hold, reset, or etc.

E-Stop should ALWAYS disable the machine no matter what state it is in or what is going on. That is the whole purpose of the button. If it does not do this then then the machine should not be operated until it does. IMO

I have stalled the spindle several times being too ambitious when tapping and have never had an alarm probably because I hit Estop very quickly.

What happens is the spindle load goes into the red and the machine just sits there not doing anything. Probably if you waited long enough it would give a spindle overload alarm.

I doubt Haas is alone in the misunderstooding.

I will say again the feed hold did not stop it, I know that it will not stop when you hit the feed hold. I did not hit the feed hold untill after it had stopped. Then I hit feed hold and reset several times before trying to release the collet. There was no alarm, and now that I think about that I'm pretty sure that I did hit the e-stop since the feed hold would not have done anything. I will go back and see if I can see it in my video.

Another thing to note if this makes a difference, we always turn the coolant off and hit feed hold before the tap makes it to the tap cycle. Then blow all the coolant off the part and out of the hole then put tapping fluid in the hole and on the tap before it tries to tap a hole.

Thanks for making me laugh your funny.

In the future don't put wrenches on a spindle when the machine is on.

It's not a manual machine with a hand break

That machine is definitely jacked up...the screen problem makes me think there's more wrong with it than could be repaired on site.

Not sure of the purpose of "has anyone seen this" posts, but hopefully you do enough *****ing that they'll swap it or money back. Problems as severe as this show up within the first few weeks on the new machines, caused by assembly problems etc.

That said, I'm signing the dotted line for a new machine in a few days and have no compulsions against it.

Now that you say that it reminds me of another thing we have been told by Haas. We ask if there was any kind of break that you could hit a button and have the spindle not turn. They told us that if you hit the orient spindle button the spindle will orient and then not turn. This is wrong also. Do not try to turn it, it will hold for a second then spin.

I did not say you pressed feed hold to stop the spindle. I was merely making it clear how feed hold interacts with the tapping cycle to expand on what Geof posted.

No, you are wrong. You asked if there was a "break" to have the spindle not turn. They told you spindle orientate will orientate and then not turn, which it does as stated. However, it is not LOCKED like you were probably implying.

Another case of miscommunication!
