Well, this just made my weekend... If anyone is familiar with this machine or similar and can offer any advice, it would be much appreciated. Here's my problem:
The machine is a 2 axis CNC lathe, a Hitachi Seiki Ht20-SII. I accidently loaded a boring bar into one of the tool slots that was sticking out the back of the holder a little too far and it caught on a bolt when the turret was rotating.
So I hit the E-stop, noticed an alarm saying something like "turret indexing fault". But once I removed the boring bar and did a tool change, the turret slowly moved to the next position and seemed to find its correct position. The alarm vanished and everything seemed to be fine.
Well, its not fine. Manually, the turret only turns one way but when running a program, the turret turns both ways, taking the shortest distance to its next tool.
So when the turret rotates clockwise (in both automatic and manual mode) it seems to work fine, but when it turns counter clockwise, it goes slightly beyond the correct position and the tool doesn't lock in place. And when the tool is in this position, I can rotate the turret by hand without too much force!!
Whats more is, now that I've pushed the turret a couple times, the tool positions no longer match the machine. ie: I call tool 8 in a program, and it give me tool 6!
So thats the scoop... any thoughts?
Anyone know how to reset the tool positions so that a program tool call matches the correct tool position? (Other than pushing the turret all the way around by hand the way I screwed it up in the first place...)
Anyone offer some info as to how the whole turret system works, and how/why the turret seems to turn just fine in one direction, but not in the other?
Anyone suggest where to get some tech support for this machine? I'll be trying Mori Seiki tech support today, cross your fingers for me...
