    Optronics 2G

    I'm new here, but recently acquired a 2G Optronics Generator.
    I only want to use it for cutting laps.
    Any suggestions?? Where can I find tool charts?? I'm used to just ordering custom tools, but want to be able to cut them myself for odd-ball scripts.
    Anyone have any experience with this?

    Look up member shanbaum he will be able to give you great information about tools and rangs, as well as what index of tool would be a great choice. I remember not to long ago a thread on tools. You may want to use the search function.

    Will that machine cut aluminium? Plastic tools are ok today but after they set on the shelf for a week or two they chang curves.

    I don't intend to cut aluminum - just plastic. We have a very wide range of tools, and a policy to order, or make any tool for out of range jobs. Usually this is only a single use, but we do retain them on the rack.
    What causes the change in the curve after a week or two?

    Don't worry about that any more. Some of the original plastic laps would flatten out in the cross curve, especially if they were clamped too hard when cutting. Now they have better plastics, better bracing and you don't have the curve change happening now, at least with the new PSI laps. I don't like the Fiberlite laps from DAC because they
    a. Smell bad when cutting (not as bad as a 1.70 index lens though)
    b. The center hole sometimes needs to be reamed out a bit if your lap table bolt is a bit ragged or oversized.

    I have an Optronics Vista generator, and it does a good job on laps, until you get in the 10D range where the spirals get too far apart.

    The problem I'm having is this generator is asking for radius curve to cut.
    I want to be able to enter a tool curve instead.
    How would I convert this if I have to do it manually?

    I'm not familiar with the operating system on that one. Is it PC-based? Anyway, call Rex at Optronics if you have any questions.

    Those machines will allow you to do that.
    Have you talked to NO about this. They are very helpful people. Also I say to Dragon, go tomorrow and pull a few of those laps and check the curves (if you have a gauge). Come back and tell us what you find.

    The 2G is a newer version of the vista. There is an simple adjustment for those spirals. Check your manual or call NO, again they are very nice folks.

    I don't know I just see it all the time. You get one off power, go to the rack and it'sone of those plastic laps. Check it and it's off. It is one of those sneaky problems.

    OK.
    <walks back to rack, grabs tool>
    Hmmm this is one of our oldest PSI laps, back when they were all colored blue.
    !.50X3.37

    1.50 = 0.887 measures .880
    3.37 = 2.008 measures 2.005

    I'm happy.

    The original formulation did have a tendency to flatten out, especially in the cross, but I thought some of that might be from being clamped too hard in the tool holder, warping the cross curve. Newer ones have the metal bars in the base to stop the distortion from overclamping, and I really don't have much of an issue with them. I still have a lot of aluminumiumnun (nods to the UK'ers) laps, but as you might know, the Oldfield won't cut a base curve flatter than 3.00D (OK, we can get some 2.87 tools), and anyway it needs a new gearbox.
    I know how to narrow the spiral separation, and usually run tools at the finest spirals. But when you get too steep, even the narrowest spirals start to spread apart

    Long as you are happy. I'd of looked at a few.

    Try double checking them with a lens clock. the curve may be correct in the center but as you go out toward the edges I've found that the curves start to get steeper.
