    There are more benefits to just quick change collets....

    The collets are more precise
    You grip along the entire length of the collet not just the end of the collet like 5c
    because of this you can make more aggressive cuts without having push-back
    The collet chuck is smaller in diameter so you have more clearance.

    Lots of extras over 5c

    Hardinge also makes a QC-65 chuck. They had a deal were you buy the chuck and get 4 free collets and the tool. They also have a 5c adapter, S collet adapters, expanding mandrel adapters for ID holding. Royal collets also fit the Hardinge. Lyndex also makes chucks and collets that fit both and surprisingly MSC sells the collets for about $210 each.

    This is exactly why I want to get a cnc with this collet setup. I feel like I could run bar fed diameters and remove lots of material. I really like the way they clamp along the length of the material and not just at the end like a 5c.

    I also found a neat tool holder for circular form tools to adapt to a cnc turret. I could easily throw my Brown and Sharpe jobs on it with the same tooling.

Somehow we managed to get two Doosans in with Big-Plus. This totally pissed me off, Here we have probably 2500 Bilz cat 40 tool heat shrink holders and another 1500 of miscellaneous cat 40 holders yet I was constantly bottlenecking because I had to order a tool that we already had 100 of.

    Is this just a warranty thing? I had a Doosan with a big-Plus spindle and ran normal cat40 holders in it for everything but the face mills and it worked just fine..
    This is not correct. They will warranty the spindle if it comes apart as long as you aren't the cause of it. This spindle is designed to run *either* Big Plus holders or CAT40 holders that are "normal" (ie not big plus)

    You do not have to exclusively run Big + holders in that machine. Secondary to that, you shouldn't be running old holders in a new spindle anyway. Follow that and the mixed spindles in your shop is a non issue.
