Wondering how many people are using a 1.5 Kw spindle? Doing my first build. The spindle arrived today and it’s a bit heavy! Has that posed any problems for others? Maybe upgrading to 9mm wide GT2 belts could help a little? I have all kinds of GT2 belts and pulleys I could work with here from other projects.
I mostly work in aluminum plate so when ordering the spindle I got the 1.5 Kw for not much more than the 500W kit. I already have a VFD from my big manual shop machines so saved on that and put it towards the bigger spindle. My logic was that I could slow the spindle speed way down (8000-24000 rpm spindle) and still have some semblance of torque left to make proper chips. Seemed like a good thought on paper when ordering, but now that it’s in my hands I think the weight could be an issue.
I searched the forum and a couple folks mentioned the 1.5Kw spindle but without much elaboration on their experience with it.
What are others experience with this?
