Sub $600 Spindle Options

Sub $600 Spindle Options

Postby TekkSki » Tue Aug 21, 2018 6:13 pm

Buying the Shapeoko 3 XXL. If I don't buy the Dewalt or Makita I have roughly $600 left in my budget to upgrade to a spindle. I plan on doing aluminium where it makes sense. I have seen the wiki with spindle options but they top about about the 800 - 1kw range.

I've seen 1.5kw and 2.2kw used on some machines and I would like to lean towards that. What is a good option with VFD in my price range? I see a ton of these things for sale so it is difficult to sift through it as a newbie. Square spindle ? Round? Does it matter?

I'm shooting for a machine that can cut aluminium and have an oversize spindle as down the road I may want to modify the machine to utilize it.

If possible:
ER collets as they seem to be a standard
I would like to be able to use up to 1/2" endmills
Would be nice if down the road I could control the VFD with code
I know at these power levels staying at 110v is probably not an option. I can wire in 220v if need be

Are you sure you don't want to just get the Makita and spend half the money on tooling and save the balance for later?

It's really a shame that there isn't an option which:

- has a narrow diameter (like the Kress)
- has a metal body and good-quality bearings in the casting which are easily replaced (like the Makita)
- has an ER-20 collet (like the larger spindles)
- is easily wired into the controls (like the less expensive spindles)
- has a brushless motor --- is that even an option?

One thing which I've been considering is getting the battery-operated version of the Makita (which has a brushless motor) and just wiring an 18V power supply directly to it.

I am skeptical of anything over 1.5kW on 120VAC. The 2.2kW will draw 20Amps or more at peak depending upon the efficiency of the VFD. Generally the cheaper the electronics the less efficient they are.

Most household breakers are 15A with wire sized for 15A based on length of run from the panel.

If you can size your wire and breaker properly, it may work fine.

It would be nice if the spindle came w/ a power plug which would limit its use to 20amp outlets.
