Proxxon IB/E

Post by willo » Fri Jun 15, 2012 3:19 pm

These things deserve their own topic.

Dremel (and most generics) use bushings and have pretty dissapointing runout see for a nice description of measuring it.

The proxxon IB/E is usually around $120+ and is simply the best deal for a high speed spindle I've found. It's capable of 20k rpm. 30k is better for some tasks but 20k is generally sufficient for milling things like pc boards, etc.

What I really like is the mounting. The proxxon has a cast (probably aluminum) neck that provides a rock solid foundation for mounting the spindle. Add to that a nice selection of collets (not just 1/8 like others) and you've got a great variable speed spindle for a very good price.

Edit: I didn't see the other category where there is some discussion of this tool, but It's got several references here, so it's worth leaving.

i've got one, i'm quite happy, i haven't cut a lot, but it's the best that i've used (other proxxon (all plastic), and a dremel)... for me it's a very very good purchase.

I have one too. Very nice indeed. I think this thread should be in rotary tools, not mini spindles though.

the last Dremel I took apart had ball bearings, have they changed that? There was a time when they went from 4 bearings to 3, and those Dremels were horrible, but I thought they had gone back.

I think the problem with Dremel tools and the poor run out they have is due to the way the last bearing is housed, rather than fitting accurately in the end of the housing they use a flexible method to hold the bearing (possibly to reduce vibration). As time passes the flexible bearing retainer gets even sloppier and so the run out increases. I have read that before the shaft gets to that last bearing Dremel tools are very accurate.

I had been very happy with my Proxxon. It was very quiet, and seemed to have enough power for what I have been cutting.

Yesterday I tried aluminum sheet metal (helping out a HS robotics club) and it cut fine all day. This morning, it does not run, but sputters and caught and then stops. Dead.

I think all day of cutting alluminum (very shallow slow passes) was too much for the tool.

I am replacing it with the Dewalt 660.

So, how long did it last? Do you think that the Dewalt would have stood up better?

I'm curious too how long it lasted. It might be worth a call or an email to Proxxon. They are supposed to have a 2 year warranty and are described as being able to run for "extended periods"

My Proxxon did the same thing a month or two ago. Couldn't have been more than about 5 hours of cutting aluminum (also at very shallow passes). Probably about 30 minutes at a time?
I haven't gotten around to trying to get it warrantied yet. Replaced it with a Dewalt which is holding up much better.
