    Viewing photos problem -for PM software people

    Same here It's been a few years since recent pictures started not to show in threads. Beeing logged in or not doesn't seem to matter.

    Rare Deckel Compatible

    Indeed, I owned an Hispano Suiza mill in the past. Interesting machine, with advanced features such as power feed (three rates !) and stops on the quill of the vertical head (no quill on the horizontal though)... But very awkward to use due to the handwheels layout. The machine had only two...

    Isoma Centering microscope

    Hi What you have is the terminal part of an EWAG WS11 microscope with arm. I have no clue about the sale value but judging from the complete example below, it is probably not that much. Much less than I would have thought for exotic swiss equipment ! Setting and measuring microscope - Ewag

    Next time, bolt a trailer coupling head to your manual pallet jack, hook it up to your truck, and offer free delivery to your customer ! ;)

    Deckel FP1 -helicoïdal milling accessory, beginners question

    Michel If your helical milling attachment has a 40 taper, the spindle nose probably has 4 radial tapered holes. Those holes are meant to mount a chuck backplate such as this one directly. No taper. Please note that the backplate in the ad is for a plain dividing head. I don't know if the OD...

    Hermle Universal index table

    Yes it does. To a certain extend. If you want it to work, your tool will never have the same exact full profile as the tapered hole, because that would mean there's no relief at all. So theoretically, you should be able to plunge, then feed the tool radially to finish the hole. Indeed, a...

    Hermle Universal index table

    Look for a Wohlhaupter UK4 then, Bruce ! As for the D-Bit tool, yes, that's the thread I post a link to. Didn't you see it ? If you decide to give it a try, you'll see that a D-bit is very easy to grind. Now just a thought for the kind of tool required to enlarge a pre-drilled hole to a...

    Some interesting reading... And guess what ? I found it on that forum ! ;)

    Hermle Universal index table

    My mistake ! I had overlooked that point..;) Nevertheless, keep in mind the key will provide some centering effect of the adapter on the spindle nose in one axis at best (perpendicularly to the key). And once the accessories mounted, you don't have access to the bolts anymore, so you can't rely...

    Hermle Universal index table

    I don't know if clearance value is very important. It must be enough to make operation easy. But if you want your adapter to be relatively easy to mount and to take off, the required clearance will be more than one can accept for a centering workholding device (be it a centering vice or lathe...

    Hermle Universal index table

    I can not see your part yet, but the easiest / best solution for keeping ID/OD concentricity in you case will be to pre-drill/tap a 90mm OD piece of round stock, chuck it up, face the end, the,finish the OD so as to be able to light press your adapter onto it,... Mount your adapter, and secure...

    Ok, ok.... You don't have to be sarcastic just because you're jealous you can't take the top plate off your 2038 ! :D:D:D;):D

    Hermle Universal index table

    And what's the problem ? :D Re-thinking about it again after all, I'm glad we did not launch production yet, because I wonder if there would really be any kind of benefit in taking the "regular" T-slot top plate of the table to mount all those accessories after all... One could just make an...

    Hermle Universal index table

    Yes, but that kind of arrangement is much more difficult to make. Plus in Bruce's situation, the centering of the attachment would be provided by the OD of the spindle nose. So no need (nor even possibility) for the short taper. I don't think it's that simple. If you make your accessory...

    Hermle Universal index table

    May be, but the bolts are best located (read : on a wider circle) to handle the loads, than an plain central arbor. Plus the flat surface of the spindle nose also plays a big role in the stiffness of the assembly. In that regard, I wonder if a central arbor would work the same way as the four...
