DB-200S Spindle USA
« on: January 02, 2011, 08:01:48 PM »
Happy New Year to all........

For my new CNC router machine I was planning to get the Bosch Colt router but searching on eBay I fount this DB-200S high speed precision spindle, 110V, 1/8” tri-split collet, max. T.I.R 0.0004”, end play <0.0003”, 2 SS sealed and greased bearings, SS housing, max speed 24000 RPM, Spindle length 5” x 0.750” body diameter. Price is $120, made in USA.

I plan to engrave aluminum, wood and plastic and since I know nothing about spindles I’m asking your opinion. The price of this spindle is less than the Bosch Colt but that is not important. Also I was told that I can use an external variable speed switch I have to control the speed of this spindle

I believe this is the Wolfgang spindle, no?

EDIT: just so you realize, you still need to buy a motor to spin it.

Right on Dave, it is the Wolfgang spindle

So is it better to get this one or go for the Bosch Colt?

If you're going to buy the motor along with it, it's going to be much more cost than the colt.

I've heard some decent words about this for engraving so if that's all you'll be doing, it should work nicely for that.

LOL Dave you may be right because I thought the motor is included. Your link is for a TB-350 and the one I'm looking for is DB-200S

I will have to ask the vendor

Thanks for the info, would have been a big surprise to get the thing and then find out that I also need a motor

There is another one listed which has 2 high speed bearings which may be better for what you plan on doing with it ( additional $60 ).
Both should work for engraving as the cut depths are going to be rather shallow. The motors look like the high speed motors used on sewing machines.
There was a guy on ebay custom making them and quality look excelant some time ago. That end play is good and 1/2 thou runout will become two or three at the end of
a small end mill just somethng to note. End play is important since in fine engraving you want to be able to control the depth quite accurately and end play can start to play
 in to what you may want todo.

I use hand pieces which are driven by a flex shaft and the motor is 1/4 hp. Machine Al 1/8" deep at slow ipm....small stuff. Never have any problems just doing engraving work.
To share my experience on using it for 3 axis work where i let it run for 4 hours or more my hand piece is getting up around 150 deg F and it sits inside a big block of AL.
No problem with the motor but i know that the bearings won't hold up / i dont konw when they will give out. I can always replace them and should add some cooling to the spindle.
Mine are  modified spindles from Grizzly and they are better than all the Foredom ones at less  than 1/3 the price.
Link shows some of the spindles i use:

The air driven ones ( Dumore, Dotco, Ingersoll Rand ) are noisy i may add. Would drive you insane if run for 4 hours!

Just some info FWIW,
RICH

Sorry but I still dont have enough info to see if these spindles are good for me.

I noticed that they come in 100 Watts or 240 Watts. Would either of these be enough to engrave aluminum or hardwood?

I bought one last year, had to replace bearing after one month and had a lot of trouble.

Just do a search for the motor, I've seen some for only $4.95 from others seller.

Maybe mine had bad bearing but when I got it, was very good to engrave PCB, not much more than very light pass and soft material like wax.

If you have a lathe, just make one, that's what I will do.

I bought an ER8 holder with shaft  http://cgi.ebay.com/New-Straight-Milling-Shank-C10-ER8-100L-Collet-Chuck-/110454114354?pt=BI_Tool_Work_Holding&hash=item19b7940832

Bought some bearing and will try making one and put a DC motor rather than AC, will be able to mount the motor at the end on the shaft rather than beside the spindle.
