VF2 SS tool change failure

[omy005]

G'day all, Our HFO has just replaced the entire tool changer cam box assembly (haven't received the bill yet!) on our machine with about 620,000 tool changes on it. A bearing had collapsed inside they think as one of the shafts was wobbling around a lot and we we're getting TT over load alarms. Factory said it's not a serviceable item?

Has anybody else had one fail?

Our other VF2SS has done over 1,300,000 tool changes with only one fault (carousel motor brushes).

Andrew.

I have several Haas machines with both carousel and side mount changers and so far no catastrophic failures, just a loose bolt or two and dirty proximity detetctors. But even my oldest machine, a 2000 VF0 has nowehere near 620,000 changes, never mind over a million; what are the total hours on that machine? A toolchange is around 3 seconds so a machine with 1,300,000 tool changes has spent over 1000 hours just changing tools!

We have had a few failures on some machines, now as soon as we get a new haas in the first thing we do is slow the arm down and hadn't had a problem since doing this. It is not noticable in the cycle time and sounds to me much nicer. If I can remember right it is param 469 factory setting is 1470000 and i have been changing it to 1000000. we also check the oil level monthly.
