Spindle Upgrade: Tramming, Locating, and Dust Collection

My machine is an AvidCNC 4’x10′. It’s not a standard size but AvidCNC’s are like legos so you can build what you want, basically. In this video, I’m upgrading my spindle to the 8.7HP plug and play spindle. I won’t be getting the full 8.7HP though. That rating comes from running it with a 3 phase power source. I’m running mine on 240v single phase which will result in around 27% material removal reduction. My power rating will be 6.4HP. That’s more than double the power of my previous spindle.

  1. Hi Jay
    If you had machined a known position dowel hole in your spoil board before spindle change. You could have clocked steel dowel after spindle swap and found the exact offset required. I know it’s too late now but something to bear in mind.
    And ‘yes’ I used to work in engineering for my sins lol.

  2. Thanks Jay for the very interesting and careful upgrade demo. Your use of decimals in inches shows you are inching closer to using metric measures.

  3. Was your machine/spindle rigid enough to machine 3/4 plywood full depth at the recommended chip load and get quality edge finishes with a 1/4″ compression bit prior to changing the spindle? Same question for a 3/8″ bit. Same question for a 1/2″ bit.
    I assume the reason for the spindle change is for the large surfacing bits. I’m wondering if your CNC has the power and rigidity to support production speed cutting with 1/4, 3/8 and 1/2 inch router bits with the stock spindle and then what difference do you experience with the upgrades spindle.

    Thanks in advance for sharing. I really enjoy your content.
