    We are converting Two of our Twelve 3M Lava mills to accept 98mm disks today!

    Just thought I'd share that. Pics to follow....

    We just finished testing the travel limits and we have the needed range to do this.

    Will modify the loading system and making custom fixture.

    No auto-loading for first experiments because we need to get this done ASAP.

    That would be awesome for the CNC 500 , using blocks sucks

    AMAZING..... the original lava mills are among the most reliable milling units on the market. shame that many are simply collecting dust. please let us know how to save these golden beasts from extinction.

    I have the back-ups for most all Lava mills in North America.
    We can make new flash-cards and HDDs as well.
    I have Axis motors, Spindles, can fix chiller units, etc.
    We have a calibration station for Steinbichler ST scanners and new cameras as well!
    I got my hash pipe.

    That Spindle can hold 4mm or 4mm collet as options!

    The CNC 500 is not made to be wet mill.

    We are using only plastic to machine soft materials. We 3d print it in 3hrs on 3d systems Projet to test idea and fit. But, now we are just going to use it and maybe no Metal?

    We leave One top side attached but only loosen a little. We remove One-half of the top to change the disk.

    If necessary, we will make metal fixture and the Lava Mill will cut it's own fixture while clamped in the machine.

    We are going to change a few things....but this fits fine.
    The spindle can get everywhere.

    We used Urine colored Resin from 3d systems.

    Ugly, right? :eek:

    20 tools.

    Can be 3mm, 4mm, or 6mm shank tools.

    We are having the final product manufactured out of White POM (aka "Delrin")

    Since we are only machining soft materials....we are going to go with this material.

    Aluminum would have been same price, but I think it may cause cracks to form in Zirconia and Sintron materials if clamped too hard on a little piece of debris. The POM will be slightly more forgiving for clamping and holding the material and I think it will absorb vibrations better than Aluminum.

    2nd prototype

    I think we are ready for production now.
