Sound comparison between DW660 and 300w ER11 DC spindle

Post by Tom Smith » Fri Feb 08, 2013 4:38 pm

Both are running unloaded, I'll do a cut test later this weekend. Pardon the gravelly, getting over a cold voice of the narrator :-)

Great!
Thanks for the video! :)

It should also be noted that the Chinese spindle is much, much less powerful.

Here is a picture of two cuts with the same G-code and endmill.

On the left is the 300W spindle in plywood.
On the right is the DW660 in hard maple.

I stopped the G-code on the left early because it was obvious that the results were going to be unacceptable.
The plywood should have cut much more easily than the hard maple but the spindle just did not have the power to cut cleanly.

I am not saying that the 300W is bad. I just wanted to point out that with the noise reduction you also have a serious power reduction.
If noise is your primary concern then the 300W spindle is probably a good choice.
If you are like me and have a large working area, you might be more concerned with max speed and depth of cut.

Yeah, the DW660 is really powerful, and if I wasn't running this thing in my apartment, then I would take the power over the noise. However, I, and others here, am sadly lacking in the super-cool workshop space catagory, so some compromises must be made :) I'm not trying to sell this thing, just provide some information for those considering it.

I am anticipating cuts in the 1mm or less at a feed rate of less than 800mm/min, as opposed to the 2mm@ 1400mm/min with the Dewalt. Sometimes tradeoffs are necessary, right? :)

Nice phone dock, by the way :)

I totally hear you on that one. I was really excited about the lack of noise but disappointed with the performance.
I am still looking for something with the power of the DeWalt and the quietness of the 300W spindle.
There are lots of 220v options but not much that runs on 110v.
By the way the garage in my rental house only has one 20 amp circuit for the whole garage including the lights and garage door opener. :(

Reminds me of the place I was in 10 years ago - nice big garage, but the breaker box for all the outlets in it was in the attic of the house. So whenever I would blow the breaker with my radial arm saw (which happened often) I had to get the ladder, climb up to the attic, and crawl halfway across the house to flip the breaker. Whoever wired that place must have been on something...

I miss that garage tho :)

Did you find 220v options with low noise AND power? Please let us know.. :)
I need 220v and the only options I have found so far is the Kress 800/1050 or the Metabo FME 737.
They both seem like a great deal and I might just buy one anyway, but the Kress lists as 89dB of noise in the data sheet.

How is that compared to the DeWalt, the "dremel" and the 300W spindles? Maybe we need a Wiki noiselevel chart? :-D

I was going for the 1.5KW chinese spindle until someone said it was 6KG, then I took a step back.. :)

What power supply are you using?
