I bought a Nakamura in New Jersey last year. when I bought the machine I had the owner run through some programs for me. BIG MISTAKE... He owned it but had little experience running one if any.
He shoved a tool in the turret and when he went to cycle it ......POW. it hit the back of the machine and would not do anything... I already paid for it....he assured me that it would be ok....
Got it home and set up...I found a circuit breaker in the rear that was popped, so I reset it. and still nothing. I found a relay that if I depressed it would rotate the turret like a fan blade. after doing research and contacting Methods....this guy told me to take a 8 foot bar to the turret and sync it up with the number on the control panel. ( it was calling for tool 1 and it the turret was at tool 4 ) I thought he was kidding...I come to find out he was not. So I don't have much faith in them.
After talking to some people in another forum I got better details on how to disassemble the turret and replace the slip rings .....Now....... here is a new problem ...
Originally the machine homed by putting a selector switch to home and moving a joystick to make it go home in Z and X and at that time two green lights would illuminate to let you know your at home.
Now the X axis light will not come on. at first it would if I would run it really slow on approach to the home....and now NOTHING.
Z home light works fine, So....I am taking things apart again....found the two micro switches that I assume the first one homes the machine and the second one is definitely machine overtravel shutdown. ( at least when I push it the hydraulic pump shuts down) The first switch appears to do nothing. I replaced both of them anyway.
I seen yesterday that someone says their are batteries that may be going dead and would provide this scenario. I don't know and really need someones help.
the control is a Fanuc 10 TF 1986 vintage I believe... it has color graphics and the FAPT conversational.
The machine is in like showroom condition ..... paint is perfect, chip conveyor, new Kitamura 8 chuck. and the previous owner told me he only used it on occasion. and the prior 3 years to me purchasing it .... not at all.
I know this was a long thread....thank you for indulging me and please any help would be greatly appreciated.
