Compressor for PM7 mill

[JonnyLathe]

Hey all, what compressors are you all with the PM7 mill using? I'm having a hard time finding out what specs are needed for this thing. Thanks!

We have a Kaeser SX3. Not sure of the exact specs. Your ivoclar rep should be able to get you that info.

By the way, this mill is awesome. We got ours about 3 years ago. Very happy.

Great to hear! I'm excited about it. Do you mill PMMA with it at all? If you do how loud is it realistically?

As a small 1 man lab with no room for the size and volume of the air compressor that it took for a PM3 on up, took it out of the picture for me. The liters per minute is the main number you want to be sure of.

I mill PMMA about once every other week. I let everyone in the lab know before so they dont think the mill has an issue. It's not terribly loud. It just sounds a lot different than when its milling wax or zirc. I do know milling PMMA is much harder on the spindle than the those other two materials FYI. Since we got our PM7, we had one issue where we had to send out work to Troy Michigan to mill while they sent out a tech to repair our mill. I think it was down for three days total. All the milling was done free of charge so it wasn't a a big deal.

I think too, that the older the tools get, the louder it is when milling PMMA.

Increase the spindle rpm to 19000 it would be much easier for the mill
