    Qt 10 turret index malfunction

    Update: so I've had 3 machine maintenance guys come out to my shop, some from my day job and one from another shop and they seemed to be as puzzled as I was. I made some spare time to dig a little deeper. I checked the motor over one more time, next the speed reduction gearbox, and found the...

    Qt 10 turret index malfunction

    That was the first thing I did, they all worked properly when the turret would actually index, but when you're stuck the only way to rotate is manually unclamp and force the turret (in the unclamped position) and it will go almost limp and allow rotation with slight feedback of the turret motor...

    Qt 10 turret index malfunction

    Yes that's correct it's a 1986 with a T2, so what you're saying is when the switch is "made" I should be getting those readings, I tried with like 15 switches and with the meter tested each wire from each switch up against a metallic surface to engage the LED light and got 24 volts on +24n and...

    Qt 10 turret index malfunction

    Update: I ordered a prox switch for PRS-3, the only one I found that matched cross referenced part numbers was on eBay, 3 days later a box of 30 switches shows up at my door. I only ordered one. Only paid for one too, called the guy he said if they don't work call him and he'll take them back...

    Qt 10 turret index malfunction

    I followed the prox wire down to where it was spliced last time it was replaced and then to where it meets a terminal coupling, I did take the sensor off and cleaned it up, put it back on, adjusted it in closer and out further with no success. Same issue, the light is there and no rotation, just...

    Qt 10 turret index malfunction

    Update: I took the cover off the back of the turret motor to look at the LED sensors, once the cover was off I checked to see which ones were lit, hit the index button and it would rotate for me. I paid attention to which LEDs were lit on different tool positions and after about 30 tool changes...

    Qt 10 turret index malfunction

    Hey guys I'm back at it again, I just recently took my turret off to clean out behind it. My thought was that chips and oil were building up behind it causing the index malfunction, after cleaning everything and putting it back on I decided to try to rotate the turret I got the alarm again...

    1986 qt 10 turret removal

    It's back on! Thanks for adding the part about it being clocked with the pin it all started to make sense why one of the splined had a flat milled on it. I really appreciate the advice!

    1986 qt 10 turret removal

    Now that we're at this point does anyone have a recommendation for getting the turret back on the splined shaft? Getting it lined back up is starting to be a royal PITA but I have help coming today. It's just not light enough for me to hold and also be delicate enough to feel for alignment by...

    1986 qt 10 turret removal

    Hey guys, I'm trying to pull my turret tonight on my qt10, it's an '86 with t2 control. I removed the 4 shcs from the black cover seen in the picture, and for the life of me can not seem to get the cover loose, trying to wedge a paint scraper behind it, put brass pins in the bolt holes to pry...

    Troubleshooting mazak qt10 spindle controller alarm

    Thanks for the advice guys! The spindle control alarm is now fixed after switching the voltage taps and it brakes properly. Now the problem is when I try to run the program, the spindle ramp up is really fast and is shutting off power to the machine. Attempt 1. I set the max rpms to 2500...

    Troubleshooting mazak qt10 spindle controller alarm

    The FR-SE showed LEDs on 12,14 and 15 so it looks like it's certainly over voltage, where are the transformer taps located in the machine?

    Troubleshooting mazak qt10 spindle controller alarm

    Hey guys, I recently bought a mazak qt10 with a t2 control with a Mitsubishi FREQROL FR-SE spindle controller and have had an issue keeping me from getting it up and running. I inspected the machine at the shop of the previous owner as it was under power and at the time was in production...
