I'm trying to get the turret working on a hardinge CHNC with a new control.
Its drove me to drink, I just said F%^& it and grabbed a cold one.
I can't get the turret to land on the locating lock pins reliably. It wants
to go just a bit to far in rotation.
The turret on this machine has two air devices. The turret index lifts the
turret and an air motor rotates it. There is also a turret stop solenoid
that engages a rod against a ratchet stop.
There are turret down (magnetic prox switch) and an eight position absolute
encoder for sensors.
First and foremost I'd like to know how the stop indexing logic is supposed
to work on the original machine. I'm finding that the turret stop solenoid
won't engage with the turret running, is this normal?
I have to stop the turret indexing(short of the locating lock pins), engage
the stop solenoid, and then try to bump the turret index up against the
ratchet stop. This goes past the locating stop pins when driven against it
hard(lot of force here). Once, I jammed the turret stop solenoid and had to
take the whole thing apart to free it up.
I'm guessing at this point. I'm thinking of trying a new (longer) ratchet
stop rod, the whole cross slide has to be dissembled to get at this. Then
I'll find out this ain't it.
If anybody know a pro hardinge repairman I can call, I'll gladly pay for
