Need Help!- Nakamura Tome TMC 20. Fanuc system 10te-f control

[Japantuning]

Hello.

I bought a used Nakamura-Tome cnc lathe. It has the Fanuc 10TE-F control.
I need the user manual for control system.
Does anybody have this in PDF-file?

I cant get the programs to start. And the spindel will not start in manual mode.
Jogging off axis works fine.
Any suggestion?


Regards,

Ronny

I don't have manuals for your machine, but I may be able to help you diagnose the problem as I serviced these machines when they were current.

There are some basic requirements that have to be satisfied before any Fanuc control will run in Auto mode and your description of the situation is not detailed enough to determine if all of these conditions have been fulfilled.

Perhaps start by answering the following questions, or at least check that the machine is in this condition and try again to run the machine.

1. Are you able to move each axis in Rapid Mode and at Rapid Speed?
2. If No to 1, have you completed a Zero Return for both the X and Z axis?
3. If No to 2, Program Run is inhibited until this is performed, but will generally display an error message indicating this when you attempt to run a program.
4. You say that the spindle will not run in Manual Mode. Does it run in any other mode? Are you able to run it through MDI?
5. If No to 4, there is a switch to select ID or OD gripping by the chuck. Check that if OD gripping of the chuck is selected that the jaws are closed toward the center of the chuck, or closed towards the outside of the chuck if ID gripping is selected. Having the chuck open will inhibit the starting of the spindle and the program.
6. Even with the chuck closed in the correct direction relative to the selection switch, on some of these machines there were proximity switches at the Hydraulic Cylinder end of the spindle (assuming your machine is using a standard setup hydraulic actuated chuck) that had to be set to indicate the chuck being closed on the workpiece. These switches had to be set to be made when the chuck was closed on the workpiece, and if during Auto operation the state of the switch changed, the control assumed that grip on the workpiece was lost and program run would stop.
7. No Fanuc controls will run a program if the spindle will not start, so I would concentrate on finding why the spindle will not start.
8. Are there any error messages at all being displayed? If yes what are they? These is a button or soft key that will display any current Alarm conditions.
9. On some Nakamuras, the turret had to be indexed before the control would operate in Auto Mode. On some, by merely exercising the turret index was sufficient, others would do what amounted to a Zero Return of the turret by indexing to index position 1 when the index switch was pressed for the first time after power up.

You don't have an operators manual, but do you have a maintenance manual for this machine? If Yes, you should find a Ladder Logic schematic and be able to follow this to see what conditions need to be satisfied for the machine to run in Auto and more importantly, why the spindle will not start in Manual Mode.

If the above does not help, post back with more information.

Bill

Hi Bill.

Thank you for fast response.

1. I can move each axis in Rapid Mode and at Rapid Speed. No probblem with that.

2. The spindel wont run in anny mode.

3. ID or OD gripping by the chuck is right, and working. i dont know if there is a proximity switch at the Hydraulic Cylinder end of the spindle. I will check that.

4. The machine is using a standard setup hydraulic actuated chuck.

5. The turret is indexing when i press the index button after start up.

I do not have any documentation on the machine. thets the big probblem..


If the mode switch is turned to M.D.I, it will say something like: **** M.D.I Stop **** **** on the display. Ore *** HND Stop ****


The info you posted helps alot thank you.

Hi Ronny,
Depending on what part of the world the machine was destined, there were different interlocks that disabled the spindle and Auto run of the machine.

If the machine has a tail stock, check if there are any proximity switches associated with it. Machines with such switches sometimes require a confirmation signal to be sent to indicate that the tail stock is either fully retracted, or extended to engage with the workpiece. Also, try extending and then retracting the tail stock quill fully after initial start up and before trying to start the spindle.

Check also for a "Closed Door" switch. Many machines with this interlock would not allow the spindle to start, even in Manual Mode.

The F in the control model reference indicates that the machine is equipped with "Symbolic FAPT". I do have a Fanuc manual for the 10T controller, but its in hard form, not PDF. This manual is only for the FAPT and will not assist with your current problem.

Regards,

Bill

Ok. This machine was destined for Norway. And it has a tail stock. i cant se any proximity switches associated with it.

I´m pretty new to CNC lathe. But have experience with Nachi and ABB robot systems.

Is it possible to change ore remove the interlocks that disabled the spindle and Auto run of the machine?

Does the machine need a program for the spindel to run? Do i have to make a program for the spindel operation?
And when i choose a program, what mode shuld i use to start it? M.D.I, Edit ore som other modes?

There is a sensor missing at the end of the spindel. I think this is for the barfeeder, and the company i bougt the machine from told me this sensor was not needed to opperate the machine. Maby this needs to be there?


I could really need the manual you have. Are you interested in selling the manual?

The interlocks on any machine are put there for safety reasons and there are no reasons to disable them just to get the machine to go. Further, it would probably be more difficult for you to disable them than it would to start the machine with all the interlocks applied as they should be to allow operation of the machine.

Given that you asked if a program is required to get the spindle to run makes me think that your problem is just with the initialization of the machine.

1. Do you know about having to Zero or Reference Return both the X and Z axis after the machine is initially powered up? If Yes, is this being successfully completed?

2. If Yes to 1, ensure that the chuck is closed according to the direction of grip switch and that the door is closed, just in-case there is a door interlock, and attempt to start the spindle via Manual Data Input as follows:

a. Set the mode switch to MDI mode.

b. Press the function menu key (bottom left of screen) to change over the soft key to function selection key.

c. Press the PROGRAM key.

d. Using the Alpha Numeric keys, key in G97 S500 M03 EOB, then press the INSERT key. The content of the MDI operation buffer memory should now be displayed on the CRT screen.

e Press Cycle start button. The spindle should start.

3. Selection of a program to run is done with the mode selection switch set to either Edit or Memory mode; I prefer to use Edit mode, then select Memory mode when ready to start the program.

a. Press Function key

b Press PROGRAM

c. Press DIR.MEM to display the programs in memory and TEXT to display the current program.

d. Selection of a program is done by pressing FW-SRCH (Forward Search) then PROG#. Key in "O" then the required program number, followed by pressing EXEC. The program, if in memory, should now be displayed.

4. To run the program, select Memory mode via the Mode Selection switch. Before you run any program, make sure you are able to control the machine and you're able to identify all switches, some important ones being Single Block, Dry Run, and Rapid Override. Don't just press cycle start and stand back; proceed with extreme caution even after you become familiar with the machine's controls. Things can start to happen at what seems like lighting speed when you're not familiar with the control.

Given that you are new to CNC, are you able to get the previous owners of the machine to help you out for a couple of hours? I know this control quite well, but its difficult to take someone from Zero via a forum. Anyone experienced with this machine/control could get you up and running within an hour, and if you took copious notes you should be able to repeat the tutorial again by yourself.

As well as the Fanuc 10T FAPT manual, I have a Fanuc Operator's Manual covering 10T, 11T and 12T, but this manual does not cover the OEM's side of your machine's operation. It does, however, cover the operation, and gives an explanation, of the Soft Keys associated with the CRT monitor, as well as a complete reference to programming the 10T control.

Rgeards,

It seems like the Zero return after start up is working fine.

I tryed the program you gave me, to start the spindel. But it vont start.

I only get: MDI *** STOP **** **** in the lower right on the CRT screen.


I have som pictures here.

Ronny

One more picture of the control panel after Zero return.

I found the problem. it was the sensor for the barfeeder.
Now the machine working fine and the spindle i running

Thank you Bill

how can you adjust the pressure of the jaws in the chuck, can you help please?

You will find three hydraulic control valves, sometimes behind a trap door, sometimes with the gauges and adjusting knobs visible and accessible through holes cut in the machine's paneling, and sometimes in a cluster mounted on the hydraulic power pack. One control valve will be for the overall pressure of the hydraulic system, one for Tail-stock pressure if your machine has a Tail-stock, and one for the adjusting Chuck pressure.

To decrease the gripping pressure of the chuck, wind the knob of the chuck pressure valve in a counter clockwise direction. And of course, to increase the pressure, wind it in a clockwise direction. A pressure gauge mounted on the valve will assist in making the adjustment, with most having a safe range to operate within marked.
