Normal work will not f^^k the spindle, it heats a bit /50-55C/ but that's all. But with that cover...
Just been experimenting with cooling of these spindles and I've got it down to sealed system with no external water tank etc which all fits inside my spindle covers. Lovely and neat running lovely and cool in bench testing @ 24K going to give it a serious thrashing cutting over weekend to see if can fry it.!!
