The resolution on the c-axis is 0.01 deg. In c-axis mode without any clamp it is possible to move the c-axis a little bit by hand, this seems to be the same distance as the cuck moves during milling. I could messure it if it would be of any use. I have tried different clamping force on the brake before, without any better results. I will check the belts tomorrow, mabe the problem is there.. I dont think there are a electronic problem in the Fanuc side, they have been here and checked the machine.
It is strange that there doesnt appears a position error alarm when the machine performes milling, is it possible that the problem known to the machine builders and that they have change the parameter ?
The whole poblem is really sad, the machine and toolholders for milling is really rigid, I even got special designed face milling units from Sandvik with capto built in, and then the machine really cant use the milling capabilities at 100% ... |
