Tools were falling out of the spindle, and then after reassembly, you can't get a tool into the spindle? Am I reading that right???
If you were dropping tools, I would have replaced the bellevilles and the drawbar floater. The floater can get beat up really bad and will give inconsistant tool clamping, but a bad floater shouldn't keep the tool from realeasing, unless its really really mangled.
Did you replace the bellevilles or just drop the same ones back in?? I tried getting cheap once and used a comparable belleville and couldn't get the tool in the spindle, removing a spring fixed that, but I wasn't getting the tool retention that I wanted.
If the machine will do an automatic toolchange(even without the tool in the spindle), then you know that the piston is traveling far enough, there is a hall effect or magnetic sensor in the base of the piston, that if not triggered will not allow the machine to do an auto toolchange, and it will error out. |
