10 HP spindle

[George484]

Hello,

I am just about to begin a CNC router build but am having quite a bit of trouble finding a 10 HP spindle.

I am posting to see if any of you guys have any recommendations on where to source such a spindle, or any other details that may benefit??

Thanks!!!
George

How big of a machine are you building that you need a 10HP spindle?

Lots of spindle here https://spindlerepair.com/welcome/

I am building a 4' x 8' machine, my goal is 16'' Z travel. The machine will be used to shape large timber components. I will be mainly running a 7'' long, 3/4'' diameter cutting tool which will be cutting through solid wood up to 6 inches thick. Based off all my research 10HP will be the minimum I want to go with.

But I am quite new to this realm and would be open to any suggestions you may have. I will be starting a build thread in the coming days so you will be able to see more details asap.

10 HP seems reasonable for what you propose. I have a 12 HP Colombo spindle sitting on the shelf. It looks like you have your private message function turned off.

Hey Jim, I turned my messaging on, it was off for some reason. I shot you over a message

[Jim Dawson]

You should have my reply by now.

The machine needs to have some serious rigidity (for a DIY router anyway) to handle a 10hp spindle. Can't wait to see your build thread.

For what you want to do, you'll want areally heavy and rigid machine.

Do you have 3 Phase power to run it

[George484]

Yes I have 200 amps of 3 phase power, with an additional 1000 available if required, so lots of power!

Are you planning to cut this deep with a milling type cutter ? Or to shape the outside of a job by swarf cutting ?

A 6" deep cut could start some serious vibrations, even when done in stages, and the vibrations will not just be in the tool, but the wood too. If you can get a good finish on the sides of the cut I'll be impressed. It's also going to get very hot in there.

I use 20mm tooling often, though only 100mm long, the best cutting are the serrated edge roughers. Something to bear in mind is the work holding, you will need to feed fast enough to prevent burning, a decent chipload is essential, and this can put quite a strain on your workholding. You also need to think carefully about what happens to the pieces you cut off, a ripper cutter will grab them and launch them out of the machine or worse drag them into the toolpath. Both have happened to me when cutting 40mm plywood.

Weight and rigidity will have to be high. My commercial router weighs 3.5 tons and it still vibrates.

You'll need a big dust extraction system. The dust hood on mine takes a 12" flexible hose and the extraction motor is 10hp. The vacuum pump is 10hp too. This all adds up to a lot of heat and big electricity bills, it's noisy as hell.

It might be easier to buy an old Biesse or Morbidelli and increase the Z travel than start from scratch.

Good luck with your project.
