    ER16 "Quick" Change Collet Chuck System

    I have a limited number of sets of ER16 Collet Chucks modeled after the tooling system used in the Dyna Myte DM2400 bench top mills. It was a limited run on the tools that were made and never did anything with them.
    They are being sold As-Is for $239 for a set of 8 holders, 1 special spindle nut, two wrenches and a tightening fixture. When they are gone they are gone. Contact me directly if interested.

    Marty mind if I share these on the Sherline site? I have a set of the Dyna's and always thought they were a great idea.

    Not a problem at all. I just used the Dyna Dm2400 as a basis for the design. They may be helpful for all bench mills with an ER16 spindle taper. Though I don't know which machines had those.
    They do eat a little bit of "daylight" under the spindle, but that's not a problem for the DM2x00 series because of their spindle head post.

    I felt doing ER16 collet chucks were the most flexible holder so went with those.

    Thanks!

    An interesting concept it is similar to the Kwik-Switch system that was used on some Bridgeport mills just a lot smaller

    Mactec, very similar concept.
    Always wondered why Sherline didnt run with it. Dyna had it figured out for a manual repeatable tool change.

    The only problem is the tooling makes it to long for such a small spindle, just to much stick out for stable cutting

    Yes the actual Dyna ones I have just have a bore for the specific tool diameter.
    They dont use an additional ER16.
    Much shorter stickout than these but still lock in with the same kind of clover nut.

    Dyna Myte's allow you to adjust the headstock up on a post giving you more spindle daylight.
    Such a small machine, they work pretty well. The spindle motor is a small 1/2hp DC Brush motor.

    I have a DM2400, purchased from Marty nearly 2 years ago, which includes his spindle collet system. It works very well. Never had any kind of problem with stickout. Everything remains rock solid.

    What I really love about this system is that numerous end mills can be pre-mounted in their own collet chucks (which position precisely and reproducibly in the mill spindle), and the tool heights measured and stored ahead of time. Tool changes during a job are thus fast and easy - no need to measure the tool height every time you change cutters.

    I've machined aluminum, plus several flavors of plastics.

    Re: ER16 "Quick" Change Collet Chuck System

    I get it guys. It may not be for everyone.
    I know of one guy that tested it on a Taig and he was happy.
    I know of two people with DM2400(John who "Hman" is one of them who has had a set for awhile and got some extras. I think John has a friend with a DM2400 who got some for his machine as well) that didn't have any of the original tooling and were really happy to find them so they could setup their tooling and tool library. (Both were converted to new steppers and Centroid Acorn)
    If you buy direct from me instead of ebay, I can save anyone here the 10% ebay commission, so I'll sell a set to anyone here for $215. I'm picking up USPS First Class Priority Shipping.
    I have 8 sets left.

    Thank you!
    Marty

    Yes they will work very well for light cutting in the materials you are using, I used to make some solid tool holder for them which only stuck outside the nut by 3mm, which worked very well for steel and any other materials you wanted to cut

    I would like to get some of the main spindle Nuts if Marty has any

    Re: ER16 "Quick" Change Collet Chuck System

    I have a few holders and special nuts left. The tool holder is machined slightly differently from the original sets. (Though, they interchange)
    What you will get:
    1 Special ER16 Spindle nut (Clover opening to accept the ears on the tool holder
    1 Wrench to fit the Special Spindle nut above
    5 ER16 QC Tool Holders with ER16 Collet Nuts

    You will have to supply your own wrench for the ER16 nut.
    NO Fixture block for tightening. You will have to make it yourself. Just an aluminum block clearanced for the taper and the 3 ears.
    $169 shipped USPS Priority Mail.

    PM me if interested. When these are gone, they are gone.

    Let me clarify a couple of things. These were a design based on the original Dyna Mechtronics DM 2000 series tool holders. These were made in China by a large company that makes tooling. The project never got off the ground, so I am selling these to recoup my investment in the project. They well made, but being sold as-is, for "parts" I assume no liability for their use and you are expected to use good practice in their use. There are over a dozen sets out there with no problems. I get asked what their run out accuracy is. .001" or better.

    The way they work is that there is a special ER16 spindle nut with 3 cut outs where the ears of the tool holder go through. There is a 0 on the nut and there is a 0 over each ear of the holder. The 0's must be in alignment when tightened up. You get the feel for how to clock the nut in order to ensure the assembly is properly secured and aligned when tightened. See the attached pictures for a visual.

    I can't have these made again, today they would be much more costly, and I don't think the market is there. If I got a lot of response, I would go back and ask for an updated quote.
    By agreeing to purchase, you understand what you are getting into.

    Marty
