    Nakamura TMC20 Turret Proxy

    Could it be that your turret may be between positions? I've had experience with my turret being in-between positions. I'm not sure about the best method for your nak if it is. My lathe I am able to force the turret clamping solenoid off, force the unclamping solenoid on through the i/o...

    Mori SL1H Turret Problem (Help source Solenoid Valve Body)

    That is interesting. Mine went from running well with few turret indexing problems to half the time not quite being far enough. I adjusted the reluctor collar which the Hall Effect sensors read and it became better at indexing one tool at a time. There is a little movement when the turret is...

    Mori SL1H Turret Problem (Help source Solenoid Valve Body)

    I don't think the scoring on the valve is wear. I think it's poor machining and not the problem. After a little more inspection I realized the area that looks bad does not come into contact with any of the rest of the assembly and the wear would not be radial. The part of the spool valve that...

    Yaskawa v1000 Brake Resistor

    When I purchased my Mori Sl1h centroid converted lathe the owner mentioned that the 500 watt 50 ohm brake resistor may not be the most ideal. Decel time on the Yaskawa v1000 vfd is set around 3 seconds if I remember correctly. I have tried shorter times and the vfd is not happy so back to 3s it...

    Mori SL1H Turret Problem (Help source Solenoid Valve Body)

    I may make a spool this weekend to see if it will get me by. I'll make a trip to the Hydraulic shop this week and see what they have to say. I was expecting it to be a some what common part so I am glad to hear you think it will be. Thank you for your response!

    Mori SL1H Turret Problem (Help source Solenoid Valve Body)

    I have also adjusted the reluctor collar and this has made it so I can at least change tools making the command of a tool or 2 at a time. I see no pattern of shared hall effect sensors on the tools that do not index properly. Although tool 2 indexes too far every time if I index from tool 3 to...

    Mori SL1H Turret Problem (Help source Solenoid Valve Body)

    Really, only pulled it apart and found that scoring on one side of the spool valve. The other side is in perfect shape. Along with indexing problems I can see on the machine diagnostic i/o display that the turret will seem to be clamped visually but the Hall Effect sensor isn't reading it as...

    Mori SL1H Turret Problem (Help source Solenoid Valve Body)

    Ok shrunk down some photos to fit. If needed I can pull it again there are 3 letters cast into the other side of the valve body. I am hoping I can get away with replacing just the valve. Any thoughts? The solenoid coils are p/n 02-101731

    Mori SL1H Turret Problem (Help source Solenoid Valve Body)

    I have had a Mori SL1H with Centroid conversion for a few years. It's been a rock solid machine. And I rather like the Centroid conversion. My turret had been a little strange from time to time but it was so seldom it was not a big problem. All of a sudden I can't rely on it to make a tool...

    Hitachi Seiki 3ne-300 Contactor/ Ice Cube/ Electrical diagram

    Solid advice. I only have a couple seconds to hit the e-stop before it trips a breaker at the panel. This is the only reason I have not done this test. Great advise. Thanks!

    Hitachi Seiki 3ne-300 Contactor/ Ice Cube/ Electrical diagram

    Thanks! PM sent! I initially made an assumption about the sound. Part of the reason was because the problem initially was intermittent and stopped with the e-stop and returned with the "hyd/lube" button. The sound is absolutely coming from both servos. Again there were a few times that the...

    Hitachi Seiki 3ne-300 Contactor/ Ice Cube/ Electrical diagram

    I have a motor contactor on order and believe due to the pitting in the points this will hopefully be the solution to my problem. In the interim maybe someone knows where I can find an electrical schematic? TIA!!!

    Hitachi Seiki 3ne-300 Contactor/ Ice Cube/ Electrical diagram

    Hello all I am working through a problem with my 78/79 Hitachi Seiki 3ne-300 with Fanuc 6t control. In the beginning the problem began about an hour into the day and would persist. The following morning would go the same way. At first I thought sound may be caused by hydraulic pump cavitation. I...

    Fanuc 5t Post Processor edits for Fusion 360 Help needed

    That is helpful! I am pretty well still at the beginning of my journey with the 5t. The early version of some of the CAN cycles, using G50 and other formatting is a bit of a curve. I feel like I've spent the entire summer getting the machine going and getting up to speed. But it has been a good...

    Fanuc 5t Post Processor edits for Fusion 360 Help needed

    I edited the forceDecimal out. I think I like the idea of out puting g code with decimals and then using note/word pad to edit them out. This has been pretty easy so far. That way I can check over some of the moves more easily while there are decimals. I've been tied up with power outages and...
