0.8 kw spindle vendor

Post by blueshorts » Tue Apr 21, 2015 6:50 pm

So I'm going to get a water cooled spindle because air cooled spindles add too much noise to my machine. Does anyone have an opinion about where to buy a good 0.8 kW water cooled spindle?

I was thinking of laying down the money for a water cooled spindle setup from Ugra-CNC:

http://ugracnc.com/WATER-COOLED-SPINDLE ... 20V-R.html
http://ugracnc.com/CNC-SPINDLES/Delta-V ... -110V.html

But after I buy the spindle, VFD, collets, and cooling pumps/setup from Ugra CNC I'm looking at ~$650-$750 without shipping added.

Then I see on ali express that I can get everything I need for $351.00 shipped:

I generally live by the adage of you get what you pay for, so with only a small amount of education on spindle quality I'm leaning towards the Ugra CNC setup, but is there any reason I should go with a different brand of spindle (more or less expensive)?

From what I've seen of people posting on this forum, random ebay spindles have runout that's worse than specified but still decent. Support is non-existent.

Ugra is the only hobby-level spindle retailer I've seen, but I think you're right to go for something the seller stands behind, especially if you are doing production work. If you're just having fun with the machine, I suppose you can't beat the China price and if it turns out that the collets are terrible you can replace them with something better as needed.

Another place you can get spindles other than ebay is
http://www.automationtechnologiesinc.com

Contact address says based in Illinois. The only thing I've ever ordered from them is stepper motors. The arrived quick and well packaged, no issues.

The 2.2kw spindle/vfd I have was purchased from ebay for about $350. Still working great since July 2013. Runout was within spec.

Thanks for the input. I "feel" better about the Ugra cnc spindle, they guarantee the amount of runout (<0.02 mm or<0.001in) at least. It's a big investment, but I think it will pay off. I use my machine for a lot of different things- my PhD research, children's toys, household necessities, gifts, maybe someday a business. My wife recently deemed my shapeoko necessary for the house and suggested we make it larger, so I guess it's going to be around for a while.

I hadn't seen the automation technologies website, If I see something I like I'll send them an email and see if they respond.

Can a shapeoko support a 2.2kw spindle well?

For what it's worth, Automation tech has been around for awhile. I think I got some steppers atleast 5 years ago from them. I recently ordered some nema 17s last December. That's all I know about them. They do have good prices on steppers.

My 2.2kw spindle is on a much bigger gantry router in my basement. It would be too heavy for a Shapeoko.

Oh by the way I bought my er collets off ebay. I just found the cheapest seller. No problems and work just fine.

The water pump I got was one from surplus place electronic goldmine. $15 or so very high quality wash down pump made by flojet. You don't need high flow rate . I believe it was a 12-24volt pump but I run it off a 6volt phone charger. At 6 volts there was plenty of water flow to keep the spindle cool and the pump runs quieter.

Weight Moving to a larger spindle can require that one (re)adjust the machine as noted in Fine Tuning --- Motor Current. Two kilograms is, if not past the upper limit of weight, very close to it.[http://www.shapeoko.com/forum/viewtopic ... 845#p24845]

That makes sense, I thought you had a Frankenstein of a shapeoko for a second.

I had never seen electronic goldmine before. The number of websites I haven't found amazes me because I do hours of searching for parts usually. Thanks for the heads up on those sources.

Ya electronic goldmine has been around forever, 20 years or more maybe. We probably order stuff from them once a month for all the different projects we do. You never know what cool stuff they have so I check their website weekly.
