Hi,
I am trying to realign the turret on a Mazak Slant Turn 15, vintage 1984. I had to remove the turret and the body to replace two studs that were stripped. The studs are inaccessible with the turret on and are too long to remove without taking off the turret body. The body rotates on a center pin and is aligned with a taper pin. It is secured by 6 bolts and 2 studs. The hole for the taper pin had been reamed to 11.2 mm, way too big for a standard oversized pin, so they cut a pin down and drove that bad boy in there. I have ground an oversized pin thinking that it will align the turret body to the factory position. However, once the turret is reinstalled there is now way to adjust the body without removing the turret, should the pin not align the body properly. That would lead me to believe that there is a way to confirm that the movement of turret body is parallel to the x-axis prior to installing the turret. The question is, what is the best way to do this?
Also, while I've got the turret off I want to make sure that the coolant is working properly. There is a white hard piece of plastic that presses against the back of the turret when the id tools are active. It looks pretty mangled and probably won't seal but I can't seem to remove it without damaging something. I have loosened the hidden set screw in the cavity of the lower stud and the one underneath but still no movement. Any suggestions?
And then there is the issue of the tailstock. Someone installed a non mazak dead center. Based on the dings, I would say that it has been tried to be removed several times. I tried to freeze it, but there was too much mass to get any shrinkage. I was thinking that I could hold a bar in the chuck and somehow clamp the other end around the center, then back off the tail stock. Theoretically pulling the center straight out. Any other suggestions?
As I said earlier, this machine is 1984 and I probably never should have never started messing with it. But I'm in this deep, Ethercat AC servo's, custom LinuxCNC control with touchscreen, and completely rewired. Any help to push this project to completion is greatly appreciated. I've just uploaded pictures of the problem at hand. If there is any interest in the retrofit I can post some pictures of that as well.
Kind regards,
Dan
