Hi all, how hot does your av70 get when you are running longer jobs? I have had my spindle for about 6 months now and I never remember it getting so hot that I can’t touch it. I keep my shop at 68 degrees. This last job it ran for 28min and the spindle was so hot that I could t couch it.
Can someone help me out on this?
Thank you
I have the AV40S, and I can tell you that runs very hot as well. Its funny, the two older spindles ran very cool, and the stepper motors were always very hot. Now that I’ve gone to the AV40S and servos, the spindle is always hot and the motors are cool.
These have a 24V electric cooling fan instead of a shaft driven fan, so the fan is quieter, and gives a consistent airflow down at lower spindle speeds, but I think probably not as much airflow as the shaft driven fans at higher speeds.
Anyway, it was 104 in my shop yesterday, and the motor was definitely hot (probably around 50-60C) but I don’t think thats going to hurt anything, most motors are made to take that kind of heat.
I live in AZ as well and I have always worried that my 4HP hitecho gets too hot, even with the spindle driven fan.
