So with all the talk in the other thread about broken pull studs lets start a new discussion on hard are you pushing your Speedio/Robodrill (BT30).
I have not broken a pull stud (Running High torque pull studs) but I am getting major Fretting. I have always noticed it since i bought the machine new.
I was also talked out of Big plus which now i wish i bought it.
The last job I was running a bunch of 1" thick 6061 plate and lost a endmill 3/4 of the way through the job. When I pulled the tool the holder was very fretted. Pioneer SX16 with a 3/8" Diamondback 1"LOC. Was doing 16Krpm, 1" deep., .100 stepover and 300ipm. Not a huge cut.
I run a 2" Korloy ripper at 16k 1.9 stepover .125 deep at 175ipm and way less fretting on the holder.
I run a 1/2" 1.5"LOC Diamondback at 1.5" deep .100 stepover and 250ipm.
So now I'm thinking these cuts are way too much for Non Big plus spindle. Maybe even Big plus.
How hard is everyone pushing and what do your holder look like standard or Big plus.
Also looks like my spindle is trashed now.
