    Cool! Always keeping machines running. You are the best on those CNC machines. Always having brilliant ideas.

    Hi Luciano! rocking
    Please talk to dude from Brazil for me!
    We have many people here from Brazil now.

    Anybody can design something complex, it takes brains to come up with a design this simple, I love the simplicity Scott.

    Well, I like it so far....?? :)

    Thank goodness we did not make any serious design flaws that I know about yet.

    I hate doing things 2 or 3 times until correct! :banghead:

    Really fast and easy to change disks. No more auto-loading automation. :(

    But still a great machine for Sintered Metal machining! (Sintron , from AG)

    The Computer controller and electronics are in sealed cabinet separate from the Machining chamber.

    Minimal risk of short-circuit from the metal dust. I would NOT machine this material in a table-top mill myself.

    On average, how many more units can fit into the disk rather than a Wonka block?

    The rectangles are the most efficient.

    Really fast to nest Eight, or Four.....Never spruing issues and takes 2 seconds to sprue.

    Machining is faster due to minimal distance to jump around in each pocket.

    overhead of material is less due to same or less wasted material.

    I hate 98mm disks!

    We just add 98mm capability because of Sintron. No other reason.

    we pay same per gram for rectangles as for 98mm disks.

    We can machine right to edge of all rectangles. ( use Super-Glue to hold rectangles to Aluminum frame and all Zirconia is available! )

    You loose 2mm ring around the 98mm disk.....so really you have a 94mm disk! ( 2mm on both sides remember!)

    First two sintron copings.

    0.3mm thickness!

    Margin is 0.05mm thick!

    Marks from us adjusting one linear axis...

    Maybe 0.25mm is possible?
    We try next!

    nice.
    how long is the sintering cycle ? and in witch furnace ? with or withour Argon ?

    Oh, we have not sintered yet! lol

    I have a new furnace here. I sell them.
    I have Three more in the crates, and regular sintering furnace.
    This is a vacuum chamber furnace and we do have Argon to displace the air.
    We use really low pressure at room temp of Argon.
    The pressure will increase with heat!
    Time to experiment with that.

    I have now Three Lava Form CNC mills with 98mm disk-holder.
    Two for Zirconia, Wax, PMMA....One for Sintron.
    The other Eight or Nine stay with Rectangles for now.

    Here is the scary looking furnace
