Chinese 500W spindle

Post by tuxsoft » Fri Apr 18, 2014 9:08 pm

I have installed a 500W Chinese spindle with ER11 collets so I can use metric and imperial tools with shafts from 1mm to 7mm.

The Good:
  • Quiet, no more screeching dremmel clone
  • Cooling air does not blow cuttings everywhere
  • Constant speed on spindle
  • ER11 collets
  • Looks better
  • Price, and helpful seller
The Bad:
  • No documentation
  • Runs hot
I prototyped the clamps out of 15mm Supawood (MDF) and manufactured the final clamps out of 10mm HDPE as I could not get thicker where I stay. Hopefully with these clamps I will be able to make a set of 10mm aluminum clamps. I plan to add spindle control.
Due to lack of documentation and my inability to read Chinese I connected the spindle as shown in the pictures my first test run was a massive dissapointment until I realised the spindle was running in reverse :oops:

Here is a video of it running http://youtu.be/cmi2YnWn9LY sorry in the rotation it lost some quality.

I am eagerly waiting to see you do the new brackt mount in aluminum with this spindle.

Can you share your stl file for your spindle mount or the source file if made sketchup

So your connection what red was ground and black was positive . if that is so I also think mine is running in reverse because I did red to positive and black to ground

Here is the inkscape file for the spindle mount, the centers for holes to mount must be 25mm from the outside edge.

Nice, that sounds super quiet! How do you control the speed? And where did you buy it?

I just bought the same spindle and I'm very pleased! The spindle is very quiet, but as you said it gets hot. The noise from the actual milling and my vacuum makes more noise;) It came with a potmeter for speedcontrol (controls the voltage to the spindle 0-100v), but I run it at full speed anyway.

How hot is hot?
touchable by hand?

General speaking electrical motors can run up to ~100C but hotter than that and the magnets inside the motors will permanently lose its magnetism.

That spindle looks nice. The last one I tried was the 400w (0-48v) and was less than impressed by it's performance (tended to stall quite often, even at moderate passes). I'm anxious to hear some long term reviews on the 500w.

Regarding heat: Making a set of mounts out of aluminum is going to help the heat dissipation dramatically! If you wanted to get fancy, you could design a pattern of shallow slots into the top of the mount profile to allow for additional airflow through the mount itself (ala how a heatsink is designed to work). Using a thicker stock of aluminum will only help, I would shoot for 1/2" or thicker.

I ran three jobs, 20 min each and I would have guess around 50-60 degrees celsius.


edward: Mine came with an alu mount but the holes did not align and the bolts where to short to make an adapter plate right then. I've sat mine up with some spacers and the stock mount for now, but I'll get around to make an adapter plate for the included alu mount. Also, thanks for the advice on making some slots.
