Hawk 150 Turret Problem

[blackbolt9]

Sometimes the turret works and sometimes it doesn't. Problem happens both with manual index, when calling for a tool, and while trying to align the machine. The shot pin seems to work and "unlocks" but then the turrent won't rotate, or will only rotate a small distance then stops and throws an error. Once in awhile it will work fine though. Not really sure where I should be looking to figure this out.

Thanks for any help!

Still not having any luck.

Nobody has any ideas? I'm not very familiar with this lathe yet and would appreciate any help in where I should start with my trouble shooting and move towards.

Thanks for any help!

Im wondering if you have a switch playing up that wont trigger the pin and there for cant send the signal to the turret motor to turn just a thought, believe the pin is air and the motion is electric,I have the same machine but thank God I have'nt had that problem, but just about everthing else,must admit now shes running well I dont believe theres to many lathes that are this versitile, great control just a bit touchy.

Not sure how to help with that description. "throws an error" probably is more than that - maybe words on the cnc display? What exactly do they say? There are lots of possible errors so w/o details it is hard to make any suggestions.... like for some of us too we don't know if this particular machine came with only A2100 control or if was made with a CT cnc too... So we dont know if it is Kollmorgen spindle or something else.... too vague to offer even far out guesses.

next time it happens, post some details and watch what happens!

Sorry, was in my own small world.

A2100 control, the error message is a Turret Failure fault. Says to check a bunch of things that I've already checked.

When the fault happens the shot pin does fire and retract. Then either nothing happens at all and the Turret Failure fault pops up, or the turret spins just a short distance and stops then the Turrect Failure fault pops up.

I have manually tested the shot pin solenoids and the pin fires back and forth properly when they are manually actuated.

I assume that there has to be an error somewhere that is telling the turret that it cannot rotate or I have a bad cable. I'm not sure how to check for a bad cable though. When I manually retract the shot pin, I can spin the turret by hand though, so I know there isn't a mechanical problem.

Thanks for the help,
Tom

Bad switch for the shot pin. Duplomatic turrets can be a pain, wait till you have to remove it and send it in. That gets pricey.

I have noticed these machines come up with a lot of errors some of which are extreamly accurate,some that are operator error when programing,my hawke has had some turret errors but mainly because of stopping the machine during a program run or a crash which thank goodness is not often.Im thinking there has to be a switch or scensor that tells the turret where it is and it ain't triggering.Hope you find its something simple.

Good detailed info! Not my area of knowledge so I can't comment other than if you think it may be some cable (to a switch? motor? encoder? solenoid?) can you ohm it out from end to end on each wire to check it?

I can offer that from past history I believe you can call Mag and ask for help and they will freely & happily give it and walk you thru this; perhaps that is a next step?

Checked all 3 prox switches and they seem to work fine. When something metallic is in front of them they read 0.685V, when nothing is in front of them they show 1V.

Yeah, was hoping there was an easier way to check cables but I suppose not. Sucks trying to hold things together on each end of a cable by yourself plus trying to wiggle it around to make sure it's not losing connection only when it moves.

Talked with a machine tech I know and he said it sounded like a blown fuse on the board that is in the turret. I looked here but didn't see any fuses, maybe I was looking in the wrong spot?


Still trying to figure this out but thanks for all the help so far guys!

That voltage doesn't sound even remotely close to me. Double check your prints, but I seem to remember them switching 24 vdc.

Hmmm, I'll recheck things tomorrow morning. I bet I screwed up and had my multimeter on VAC instead of VDC. Thanks for pointing that out! DOH!

And remember, if it sees a switch flicker during index/clamp/unclamp, it will throw up the turret error and stop the turret.
