I have attached a 14cfm compressor to the spindle, I'm getting a not enough pressure alarm during a tool change on a linear magazine. After a tool holder is released, a large volume of air continues to escape from the spindle nose, and the alarm is activated before it can get the next tool. Any ideas please? If I manually release a tool holder by presing F2 it releases the tool and there is no continued pressure loss. It seems like when performing an automated change the tool release is permanent.

Yep, the hsd/controller will keep the clamp open while doing the tool change.

Pretty sure my last Canadian made machine did the same.

That said, I can't describe mine as a large volume of air. I'm running a 12.5cfm at 100psi compressor and I can have issues but only when an air gun is being used.

Thanks for the info. Yes a lot of air is escaping after tool release. The compressor is rated at 14cfm at 90psi and I'm getting the pressure alarm when I change between tool 1 and 2.

What pressure is the tank. The alarm is low pressure, not low volume (that's a whole other issue, needless to say try to avoid that one).

The alarm triggers in the 80s so it might be a little too high. It's the green box (usually) with the pressure indicator.

I have not seen a machine that would close and reopen the clamp during the tool change. And as long as the clamp is open, the air keeps blowing through the spindle to clean the cone. That's perfectly normal, you just need a bigger air tank.

You don’t have same spindle as us so I’m not sure how Mach air it takes. Did you specify the spindle?
