Nice upgrade Schallbert! Half an hour warm-up procedure.. My HSD requires less time. I refuse to buy a spindle that requires that huge amount of time. In my work i don't use the spindle for that long closed period of time, even with ATC. It's a dealbreaker for me wasting that amount of time before you can think about using it.
This is the required warming-up for my 9kw HSD spindle; 5 minutes, perfectly acceptable. Hiteco uses 2 minutes 50%, 2 minutes 75% and 1 minute 90%.
50 % of the maximum rated speed for 2 minutes.
75 % of the maximum rated speed for 2 minutes.
100 % of the maximum rated speed for 1 minute.
My HQD ISO30 atc spindle doesn't require a warm-up, according to HQD, but i prefer to give it a slight swirl before hammering it. For light opps (drilling <6000rpm with <6mm drills) i don't bother to warm her up. It's an air forced cooled spindle, but i tamed down the 70W fan to a more suitable level (with a WOT above 29 degrees) I've used it two entire day off and on for some work last week, but the spindle was still lukewarm, well below 29 degrees even. (haven't used it above 14000rpm, cutting HMPE)
