Thread: Suhner 1550w router spindle

Hi Sapherion,

I'm interested. Just a few questions - this is obviously a quality machine - have you measured the runout with a bit in the collet? Also, what do you find the advantages are of changing to a VFD and spindle? Thanks

Hi mate,

I haven’t measured the run out, but this is my 2nd Suhner spindle I’ve used. They are designed for heavy duty industrial grade cnc work and runs very quiet and cool. I dare say the run out would be absolute minimal but you are welcome to bring your gauges and measure when you test it out.

As for the vfd spindle, I couldn’t tell you spend more time on it!

There are lots of reviews online about it, I know people are deterred from the fact that you have to watercool them.

Cheers

Ok, I'd expect the runout to be minimal too. I live in QLD though (no lockdown atm, yay!) so wouldn't be able to measure it before purchase. So were you happy with the performance of this unit in a router table? Any drawbacks that you found?

I have no experience with VFD spindles (but I do have a VFD running an induction motor), but as I understand it, yes, some are water cooled, but others are air cooled.

Also, you mentioned it is wired for 15amp - it was a bit hard to tell from the photo but does it have a 15amp plug with the larger earth pin or a 10amp plug? I'm not sure that a 1550W input would need a 15amp plug as I assume it's a brushed motor.

Yes it is a 15amp plug with the large earth pin.

I have been using a similar model in the suhner range previously and a number have people have commented how quiet it runs. Never skipped a beat and what I like most is there was never loss of power even when pushing dense timbers thru the bits.

See below how it was mounted also.

Thanks Sapherion, sounds like a great unit but on further reflection I'd prefer one that takes a 1/2 inch bit natively. So I'll pass this time and leave it for someone else.
Thanks

Price dropped to $300 for a quick sale!

Hi Sapherion,

Can you advise what the diameter of the spindle body is and does it take a ER collect?
I want to check whether it will fit my cnc.

Thanks!

Hope these diagrams help. It doesn’t take an ER20 collect, slightly smaller but I can’t find the size specs.

Thanks. Doesn't look like it fits so will give it a miss this time.
