    Default Tooling for cutting wood on a CNC lathe

    With all of the CNC routers now available, there has been (thankfully) quite a bit of new tooling appearing for cutting wood on a CNC mill. However, there does not seem to much if anything available for cutting wood on a CNC lathe.
    In particular, I am looking for tooling that will enable me to cut sharply defined profiles (like on a stair ballister). Also, tooling that will produce a nice surface finish on wood. Most of the tooling that I have experimented with leaves the wood fuzzy at best. And nothing that I have found will duplicate the sharp profiles commonly found on architectural woodworking....
    Any ideas where to look?

    It might not be tooling but speed of your bit.
    But someone that has more exp. than me might know better.

    I've only been cutting wood for about a 14 months on a probotix's machine at 15k rpm.
    I know most cnc lathe's only max out at 4k?

    Yeah you could be right about that - my lathe maxes out @ 2500 rpms. That said, my mill maxes out @ 5100 rpms, and I have been able to get get beautiful results cutting wood.
    ToolsToday sells quite a bit of tooling made specifically for cnc routers, that I have used with great results on my mill. Unfortunately they don't carry anything for cnc wood lathes.
    There are videos online that show custom-made machines producing beautiful work in wood, but I have no information about the tooling that they are using.

    rarely I turning porchspindles, and making replacements for stair spindles..

    the vgct insert what you need.. they have one type, without chipbreaker ""dots"" and ground, sides use to be 3-5 deg undercut..
    need straight, and left-right toolholder..

    Taegutec carbide insert VCGT 160408 FL K10 wholesale VCGT160408FL K10 for Aluminum -in Turning Tool from Industry & Business on Aliexpress.com | Alibaba Group

    its only for showing what approximately I thinking..

    finish,

    as others pointed out, the federate what determine the surface.. the feed shouldn't exceed the tooltip radius at finish pass..

    for slim spindles, you need steady rest on the middle..

    the posted video shows if you don't try to hurry, but let tool working, it makes a nice finish..

    Thanks for the tip! Any idea where I can find 1/2" or 3/8" shank holders for these inserts?
