Tool stuck in Integrex I400s (Capto C6)

[Mcam Nut]

We have a tool holder stuck in our mill spindle, we actually clamped the tool in the main spindle and tried retracting in z, with out any luck.  has anyone had any luck removing a stuck capto holder from an integrex?

That is a new one. Need to get a hold of service before you damage the machine.

Maybe the stroke of the draw bar release is being blocked so it can't release.

Not an Integrex...but a Mori. It was stuck in the B-axis head. ended up being the coolant tube had worked its way loose (maybe a couple turns). So it happened at the toolchange. Didnt know it until we went to change tools. The coolant tube was swaged onto the spindle through coolant. Turned into a service call, set the machine to unclamp and then pried the tool loose with a slide hammer locked into the tool. I believe the only damage was to the toolholder and a snap ring in the spindle. assumed we'd damage the coolant connector also but dont remember.

Now all coolant tubes on my machine have lock-tight on the threads before installing the tube.

 

Good Luck.

We work on the waterfront right off the ocean, turned out to be bad corrosion on one of the holders that hasnt been used in a while, got it out and cleaned and oiled every holder, few taps with a ballpeen on the holder did the trick, dead blow was too soft i guess

Was worried the drawbar failed, not an easy job on an integrex 400

There's only ONE way to handle that in nearly all cases and you're not gonna like it. Ask me how I know. <laughter> I mean there may be a SLIGHT chance you can remove the tool and tighten the coolant tube through the tool's bore but that is a "do you feel lucky" scenario. 

Removing it will most likely involve a die grinder with a carbon fiber blade and you're going to cut the holder 5-10mm  below the face of the spindle. Rotating the spindle by hand and not going hard on it until it is through.

 

JM2CFWIW YMMV

This also happened to me a few years back . I cut the tool at its very base with a huge  angle grinder and was able to reach the tube and screw it out of the holder.

It was a DMG DMU 60 with a 24 000 spindle. 

The service  guy  that cam to see this quoted me 2 months  waiting time and removing all the spindle from the back , my cutting lasted 15 min  and he took pics  of

huge sparks flying from a grinder as if I was crazy or smthg :) .
