  • jet JMD-15

    I just bought a used Jet JMD-15, anybody has any experience with these machines? It doesn't have any accesories, any sugestions as what to buy?

    I'm not familiar with that particular machine, but you likely need, as a minimum:

    1. Collets -- 3/16", 3/8", and 1/2" will get you started. IMO good collets are worth the money.

    2. A drill chuck, either on a 1/2" straight shank to fit the 1/2" collet or on a shank to match your spindle taper, it doesn't much matter either way.

    3. A milling vise. I assume what you have is a mill/drill, in which case probably a 4" vise would be about right.

    4. A clamping kit to fit the table T-slots. T-nuts, step blocks, clamps, studs, and nuts.

    Add to that list: end mills, sets of drills, sets of parallels, a boring head, a rotary table, a dividing head....there are no end of ways you can spend money! Get yourself a copy of the MSC catalog www.mscdirect.com (it's free) and look at all the stuff....

      JMD 15 Mill Drill

      We have a JMD-15 in our lab at work. Pretty much your typical mill-drill. Not bad really. Typical issues with loosing registration when you raise/lower the head on the round column. Ours could use a good clean and lube as the table sticks a bit. Some of our engineers/tech's that use it don't have a clue. Present company excepted of course.

      Pretty much everything that SGW said about tooling applies. It's an R-8 spindle so get a drill chuck for that that has the thread for the drawbar. We have a full set of R-8 collets but typically use only the 1/2" and 3/8" most of the time.

      We have a drill press vise that is less than optimal but useable. Try to get something better if you can. 4" to 6" (MAX) wide jaws with a way to clamp to the table. Defineately a clamp kit. Those aren't too spendy.

      Enjoy!

        I have a Jet 16 M/D,and second all the above suggestions.I added a gas strut to the side of the column to help in raising the head.(Two fingers instead of two hands).Also use a small laser pen ,held to the head with magnets,pointed across the shop at a vertical strip.Point the laser at the strip,raise the head,lower the head,point the laser at the strip again and things fit fine.Make your own power feed drives,use small gearmotors,variable speed drills,etc.

          I had the same model years ago. Sold it to some guy in KY. I was using it mainly as a drill press. Worked great for that. Milling was another matter. I'd have to crank the 2 head bolts down with an air wrench to keep the head from twisting.

          "Also use a small laser pen ,held to the head with magnets,pointed across the shop at a vertical strip"

          Very good idea George. Wish I had thought of that when I had it. Would have saved me alot of time.

            I have a Jet 15 which has an MT3 spindle taper. This is an older mill, but not all of them take the R8 collets.
