    medical mfg standards

    My company is going ISO 9001/2000. We are in need of a reconised manufacturing standards book that we can keep on site for auditing purposes and to use and implement. Our contracted "trainer" in the ISO process gave us a monumental handbook used in aerospace. We are a medical device mfg. with a...

    6 ball versus 7 ball ceramic bearing design

    "Are the HC bearings being touted as a speed secret due to "reduced friction?" Yep. Exactly. I know loading is a problem as ceramic isn't exactly "load bearing material" Some people just want too much. thanks for your replys!

    6 ball versus 7 ball ceramic bearing design

    6 ball ceramic versus 7 ball design in a "608" size. The application would be in skateboards. I have been asked this question and feel that maybe 6 balls would generate too much in the way of sympathetic harmonics in the cage leading to vibration and that 7 balls would help to cancel this out...

    "oil treatment" of metals

    Thanks for all your replies, they have been most helpful!

    Yes tripleZ, actually these are stamped parts. Sintered pieces I can understand, but stamped??. I think the PM was feeding the chiefs a line of crap. At our place we do Class A medical/cleanroom work on one side and on the other side we make fishing reels. Go figure. The reel side of the company...

    10:1 ratio long tools

    that .120 radius on the edge of your tool prevents decent penetration of the cutter into the material. -try smaller radii and increase feedrates. -what shape is your spindle in? -locating tapers ok? -try a 3 flute cutter. -buy a 5 axis mill

    locating to a centerline of a hole that use to be round???

    have you tried diamond shaped locating pins?

    "oil treatment" of metals

    Our since departed plant manager has previously perscribed a dubious "oil treatment" of many stainless steel components in an assembly of a certain product we make. No one seems to know if such a treatment actually works. I have taken on the task of flow charting the mfg. process for this...
