What spindle is that? Aircooled? How many hours you have been using it? What seems to be proper speed range?
Always with the questions....
It's a 60,000RPM spindle (obviously), 300W and about 50mm diameter
It's water cooled and has an ER-8 collet. Less than 15minutes run time on it to date, but that will change soon.
I bought it for two reasons:
1. I did some 3D machining of MDF vac forming plugs last year, lots of fine cuts at 20KRPM... Those jobs took anything up to 6 hours to run on the big router and getting a decent finish was a hassle because the toolpath was only using the very tip of the ball nosed mill. The idea is that 6 hours at 20KRPM=2 hours at 60KRPM and this is good!
2. We sent a design off to be 3d printed as a final check before we had injection mould tooling made. When the prototyping company heard that these were t o be IM check parts they flatly refused to 3d print them and insisted that we let them machine them from ABS on their 5 axis machines. The parts came back absolutely perfect! I've had parts SLS and SLA printed before and they never looked anything like these machined parts. I could have easily sold them as finished product. So the intention is to add a couple of axii to the mill and try to find some 5axis CAM software so that I can do this at home.
