Hitachi Seiki HT-25 with FANUC 10T control trouble

Man I thought the transition would be easy. I'm a HAAS, FADAL VMC machinist. Thought buying this Hitachi Seiki HT-25 turning center for the garage would be an easy transition. So after learning how to home the x/z I managed to Z overtravel hard. Really hard. Lol. Initial error codes were 0T007 and EMG Was able to clear the 0T007 but can't get the EMG to go away. I hand turned the ball screw to clear the micro switches putting the ummm head in a clear zone. Checked the microswitches for action. Seem all good. Any assistance would be great.

Hello,

At our factory, we're are working for several years with a Maho MH-800C
Last month, the Philips CNC 532 did not boot.

We've checked cards and found nothing looking bad. We have bought a spare graphic card and replace the old one and the issue remains :

Has someone any idea about what the message " load XTP or boot with inp low " means ?

The battery is new.

Thanks for your help !!

We have a mori seiki m300l. we keep getting an intermittent m350 error. Z axis pulse coder error. we have had both mori and fanuc techs out here to troubleshoot. we have replaced the y-z servo amp, the nc computer the z coder, z coder cable. the tech have been able to get it working by swapping parts but a couple of weeks later the problems come back. we found by unplugging the z coder cable and plugging back in we can get the alarm to clear, we just have to rehome all the axis's. Now it still rehomes but the first time the z axis moves in the program it faults. any ideas?

Linear Encoder MAHO600E

I all, I have a MAHO MH600E cnc 432, but no can move the x axis, this say Alarm X02: (Alarm measuring system fault), i suspect what is the encoder model AE LS 403 Heidenhain.
Seeing the datasheet this have 1Vpp power suply of 5v, resolution is my doubt say 1um/0.005um, if anyone knew which of these two is the correct.
other data is Grating Period 20um, and System Accuracy Grade of +-5um, here is other doubt, the diference between resolution and accuracy, why is the difference so much?

I thought that the precision should be less than the resolution.

This alarm refers to an encoder problem?, should I change this?

Mori MV-80 tool changer issue

I've been having an intermittent tool changer problem. It will change tools but then the arms stays in position still at the spindle. I figured out if I press on the side of the tool lock solenoid it will carry on and run. Lately I've been having to do this at every tool change and that's getting old quick. I've messed with it but I can't figure it out. Could it be a bad solenoid? I posted a video on youtube of it. Hopefully the link works. Thanks

DMG NEF 400 Turret not locked

Hi All
I have a NEF400 which is throwing up an alarm. It says, "Turret not locked in position". I had this the other day and gave it a good blow off and that fixed it. No luck today though. I'm guessing I will have to pull the turret down and see what I can find. Does anyone have any ideas on this one?
Cheers

DMG MORI 800 ecomill SINUMERIK cabinet door auto unlock - possible?

Hello,

Have been working with HEIDENHAIN and FANUC for most of my work career, but now hit the rock with the machine in the title. I use it from two month already, and found more disadvantages than positive sides but my question is not for pros/cons.

So, how can achieve the goal to unlock the cabinet door automatic after program end?

Well, I can just remove the lock pin from the screws and stuck it in the locker unit(will solve many of my troubles) but it still is in warrant and I`m not allowed to do so.
Should of be some parameter that can be set/add and when M30 comes it unlock the door.
Over my research over the internet, come some similar cases but any of suggested M-codes not work for me. From SINUMERIK suggest was to ask the machine builder, and from DG MORI support so far has come nothing.

If someone already has don that or have clue, will be glad to hear. The only one situation, in which that very process happen as I wish to mimic is the TOOL UNLOAD macro. When unload and unlock the door, but I have no access to that macro to open and see it.If that is possible at all with 1-4 access level.

Thank you in advance, even to take a peak in that question.

DMU 50T Upgradeable ?????

Hello Friends, I have inherited a DMU 50T 1998 it is Millplus and the iron appears very nice.
It was apparently at NIST before we got it. The CRT is Kaput from what we know. I have had it here 2 1/2 years and have done nothing with it. Have not even powered it up. I spoke to Heidenhain and was told yes it could be brought up to newer spec's and that they try to support Universities..... I was told it would be around the mid $40's to do this. This would kill my budget for the next 3 years.... But if it were to be a nice machine I would do it..... I am an old guy who is in his 60's and have not seen refurbished machines work out very well. But would this be something that might be a nice usable machine if done by someone that knows their stuff. Am I crazy ? I really try to not waste money for taxpayers and for research, I may be able to get the money to refurbish this from a grant as I am being asked for more and more 5 axis work and how much a new 5axis would cost. How fast a machine cuts is not as important to us as is the precision and ability to get the parts machined, I like the size of this machine and would rather spend $50K than $200K on a machine. Thank you for any wisdom you may have. -matt

Hi good day,

I am checking a Maho 500c, this have Philips cnc 432 control, the second pcb of the side left is Centr. Proc. Mod have fail, i remove this and screen have the form of chessboard, then i put other pcb of other control 432, then screen is re-established but say error M01, have some doubt

The pcb original have code 4022 226 3340 with the CI 6053/310 , CPU 620,
and the reemplacement has code 4022 226 3381 with this CI 6053/311 CPU 713

This can affect the constants?, because when i enter to see them, they all appear with the label "incorrect".
Or this is due only to the low battery.?

thanks

MAHO 1200S CN532 Edit Parameter / Z axis refence point

Hello,

We try to start up a 2nd hand Maho 1200S we bought and after some small issues we tryed to
move to reference point of the 3 axis. for some reason the Y axis goes to the end completly then goes back the whole distance.
so he doesnt find his refence.

i dont know if this is a parameter lost issue of problems reading out the liniar philips position.
or lost parameter.

so we tryed to edit parameters but for some reason i cannot change any parameter.

i followed the steps described in the manual but that doesnt help.

also changing parameter 80 from "0" to "1" isnt possible
i tryed changing with e-stop, turning the keys in back and operator panel, change par 80, cleaning lineair measure system, ....

nothing seems to help for this.

if someone know any advice? or explain what i do wrong to adjust parameters?

thanks a lot!

Mori-Server - will it ONLY work with local administrative rights?

August 9, 2018, 1:08 pm

Not a machinist, but thought maybe someone on here could help steer me in the right direction. Manufacturer with multiple DMG Mori machines, using Mori-Server for communication. Without administrative rights, Mori-Server launches but throws up a communication error when trying to talk to machines. This error appears to be identical to the one you'd get if the machine itself was turned off. If you run the software as an administrator, communication works just fine.

Has anyone else had this experience? Software has been run throughout the years on XP, Vista, Windows 7, Windows 10.. all with the same issue. We've put a bandaid on it in the past by allowing machinists local administrative rights on their machines but we are no longer able to do this and have to find a solution.

If there isn't one, is there a comparable or BETTER piece of software we can use for this functionality?

The machine Is ready for start but I can't setting works zero And tools offset.

The machine come with some parts programs but Is not possible run any part programs becouse don't know to do in it machine.

We are doing the setting zero similar to other lathe machines with Fanuc control but the toll Is far to piece to mechanize.

Please help me to solution it trouble.

Hello guys.

My friend got some parts, it says on the box DMG MORI and its aparently from machine nt430dcg/1500sz.
Parts are new and in boxes but we have no clue whats the value of it. There are no papers with them.
Can you please help us to identify those parts and value them?
They were left over from a company last year as the van who drove them crashed so company left those parts with him as they got payed from insurance.

There are 40 "head" tools and the "chain" head holder or how that is called.

Cheers,
Ales

Mori Hori 2001 era with Lube issue

Ive got this mori horizontal where the guides and screws all look dry (and very unfortunately the Y axis is noisy).
Any how the machine is equipped with two oil units that appear to be working. Easy to say as they are the oil dropper design where you can see oil dripping through the sight glass.
I'm familiar with Bijur and other makes that are just pumps (Haas etc) with inline restricter that eventually plug up and need of maintenance.

so where to look on this beast?

Need help with CELOS on Dmg NLX

Hey,

I am new to the CELOS system on top of the Mitsubishi M730UM control that came with the NLX on our lathe. I have a question about the tooling system and would be great if someone could explain it to me like explaining it to a 5 year old. The manual is not helping in this issue.

The problem is with the tooling system. I don’t understand the "Tool Group” function, what it does and why is it used instead of just defining tools under the "All Tools" section. The “Tool Model", as far as I understand is used for interference checking (if there is any other use to it would love to know) but, really can’t understand the how the tool registration in different sections work and why there are different sections for tool registration and why I have to define offsets in certain ways or they are not recognized etc. etc. Would love a short tutorial on this.

Thank you for the help.
