Toolchange

Good morning,(or afternoon, or evening)

We have a large diameter thread rolling tool (140mm) in a 40mm sidelock capto C6. It's 250mm long (from spindle nose) and 7.6Kg.

It looks and sounds terrible when being changed (drooping in the arm, and loud thud as it clamps in).

It was originally described as an SL tool, then we tried H, but I couldn't see (or hear) any difference to the tool change process.

I feel it should have BOTH descriptors.

Okuma have told me I can change a sys para to slow the arm speed down, which I will do now, but I don't want every tool change slowed down.

Has anyone had experience with large, heavy tool changes?

Any advice greatly appreciated.

Dave.

OK, I've got to stop being so hasty in putting up posts here :o

Looking through the parameters, we quickly found, M/C User Para> ATC> Heavy, listing EC and EZ percentages.

Strangely they were both set at 100!

EC is now 70 (arm rotation speed)
EZ is now 30 (positioning speed)

Everyone's happy now.

But why does the machine have these values at 100 by default?

Also noticed that the large dia tool description also used the new speeds.

Yes that sounds correct 100% is the default value

But why does the machine have these values at 100 by default?
1. serial communication settings;
2. IGF parameters adjustment;
3. touch setter location;
4. ATC tool change settings;
5. correction of errors on printed manuals ...
are the task for machinetool supplier.
Retailer must be busy :)

HMM, yes Okuma may be busy, but they're nowhere near as busy as we are!!

If 100% sounds right, then 0% must surely be NOT right? That's what was in our Macturn when I had a look this morning.

Curiously, changing them to 50% had no effect that we could see. Maybe there's a BIT somewhere that needs to be turned on or off?

Be careful here as not all parameters are the same between Macturn and Multus machines

1. look at manual. Parameters are not the same for the same control
2. since "0" doesn't makes any sense, it means "100%" at this case.
