There is no alignment procedure, there is a tool change offset and grid offset to line the gears up so the turret can clamp properly. Was this machine involved in a crash that you suspect that the turret is off center? To properly align the turret on the ST lathes is by making sure the wedge,turret box,spindle head stock are all square.. then you move the spindle head stock or wedge to bring the tool on centerline. Unfortunately it's not like the SL's where you can adjust the turret radially on the couplings. The ST couplings are actually machined into the casting so they aren't adjustable.
Have an ST30 that has the same problem. Knocked the turrett out radially. Also knocked the spindle out. We can fix that. There have been several instances that mentioned the wedge. Makes sense seeing as the ST30's are machined in place. Are there drawings available that shows the position of the wedge ? Or can anyone tell me the proximity of where it is located ?
The wedge is the angled casting that the turret box rides on. There is no set location it's mounted on top of your z-axis linear trucks. You end up removing a lot of sheet metal to gain access to all th bolts on the wedge. You square the wedge up to the spindle face. That's after you square up the spindle casting.the bolts on the spindle head castings are torqued to 450-600 ft lbs. which you will also have to remove a lot of sheet metal to gain access to those bolts as well.
