I had been thinking about having a special insert made to do exactly that, but I just haven't had the time. One thing that I was not sure about is what normal wiper geometry was like - in other words is the whole wiper actually in contact with the feature you are cutting, or does it have some relief, just less than 5° that an 80° insert would normally have?
The feedrate of .0005"/rev. is the other thing that I was not sure of. Would a wiper still be able to aid in this situation? I suppose it depends on the geometry, which I was unsure about.
We spent about a year of messing around trying to get all the other problems worked out of that particular part, and product line, and when everything works I don't mess with it anymore, because it was so seldom that everything would be going right at the same time.
Right now buying stuff off the shelf is about the only option that I have with all that's going on around here. So far this year we have made almost exactly twice as many production parts as we made in the whole year last year, and it's only July. Have open orders for another 60% of last years production, with more every day. Last year we did 2 1/2 times the production we did the year before, etc. Got nowhere near enough dudes in the shop, and we're running machines
24/7, literally.BTW, we have a BN20 coming in some time next week, but maybe you know as much about that as I do. Thanks for pointing it out to us, I saw one that Traver was showing at a small local toolshow also. Can't wait to see it here.
