Spindle Speeds

[Muzzer]

Good point to check the required spindle power for a planned operation. As well as checking the spindle motor is powerful enough, it's often worth checking how much or little of its capability you are making use of.

Lots of Youtube warriors seem scared to get anywhere near what their machines can achieve and have little idea where that is because they never check. My larger machine has "only" 3kW but when you see what 3kW can do, it can be quite a revelation. If you experiment and go a little too far, what do you have to lose? Cutters aren't expensive and underwear can be washed.

There are a few free f&s apps beyond the fswizard that include spindle power estimates. And many VFDs can display the actual load as a % of max.
