Hi

We have a Yam Ck from 1991 i think, dont know if its 1 2 3 etc since we dont have any numbers on it. It uses Fanuc t15.

I was using the machine after just sitting for 1-2 years. When i was making a measure cut i pressed on the wrong button and activated the turrent. Changing tool while cutting I hit the emergency button and stopped the machine. i was smoking from the tool holder and i destroyed the tool.

After that the machine have problems changing tools.

If i turn the turrent by pressing the button it goes round and it stops like it should, then the turrent goes back into position and then it starts to beep. The turrent looks like its on the correct place and if i shut down the hydraulic and start it again the alarm is gone.

I can't see any damages on the turrent.

Is it a senor for position

I dont have any drawing on the electrics or mechanics on the machine. Only on fanuc system and parameter

BTW the seller told me that yam is a copy of mori seki. is this correct.

best regards
