I don’t have a VFD:
Hi Guys,
I just found that Maffell got two new spindles out with a manual quick tool change.

what you are thinking about ?
did some of you is already using Maffell spindles ?
The only thing that keeps me away from this are the Brushes… i am using a Chinese spindle and that thing performes super and it is very quiet even with air cooling im around 60db. (without load)
But a missing tool change always bothers me…
what are you thinki…
and I just use the default feeds and speeds in Carbide Create for the most part, since my stuff is all one-offs, and the worst thing that happens if a cut runs long is I stay up late monitoring it.
There were a couple of threads which hashed this out pretty thoroughly previously, one was:
A couple thoughts:
The 65mm VFD spindle is already capable of a lot. This was a test where I pushed it very close to stalling, but if you back off the speeds just a little bit it can be run reliably: https://www.youtube.com/watch?v=UqL-VyHb8l0
Yes a larger collet is nice, but in aluminum I would basically never use a 1/2" endmill unless I was doing light surfacing. Bigger endmills have to be run at lower RPMs, and you’ll fall out of the torque band of the spindle. The sweet spot for aluminum m…
and see:
It was Fusion 360’s Adaptive Toolpath. Nerdy details are as follows:
Tool Type: 1/2" 3-Flute Flat Endmill, ZrN Coated
Toolpath Type: Adaptive Roughing (Fusion 360)
Spindle Speed: 18,000 RPM
Feedrate: 4320 mm/min (170 in/min)
Depth of Cut: 4.8mm (3/16")
Stepover: 1.2mm (0.05")
Note, we did not push the machine or spindle to failure. We had even more performance on tap, but opted for these settings because the cut sounded pretty good. Also, if you push much harder, the chips coming off the …
but like I said, the folks in Sales should be able to answer that sort of question — that said, the bigger question is what folks make:
