We have to use the "spindle run-in" program which circulates the accumulated oil out from the spindle and allows it to run at higher speeds. It's always very noticeable because the spindle gets extremely hot if we didn't perform the run-in program, afterwards the temperature is more normal. But that run-in program takes hours to complete..
