    Toyoda Grinder single point diamond dresser question

    I'd like to find a way to automatically adjust the feed rate of the single point dresser based on how many dressing cycles its made. A new dresser has a .016 radius on it and sits at a 30° angle from the wheel. After dressing the wheel 50 times or so, there's a flat worn on the diamond. After...

    Do Heat Shrink and Hydraulic tool holders really improve tool life?

    I've see tool life improve by nearly 10x when milling sintered powdered metal parts.

    1 - 1/4 8tpi thread drill size

    I agree with the Ø1.125 drill diameter. The Tolerance on the minor diameter ranges from Ø1.140 to Ø1.115 so depending on the thread percentage your aiming for, you could fall anywhere within this zone and be ok

    What could cause my thread pitch to be off in a G76 cylcle?

    When they said "gaining pitch" maybe they meant gaining pitch diameter? Are you sure that it's not just a a taper issue?

    Does this count as "computer aided manufacturing"?

    This is for you lathe programmers who don't always have access to a PC. I wrote an app to help program chamfers, tapers, fillets, or a combination of the three. Check out my video: See more at cncdirt.com Thanks, Shane

    Rotary Broaching aluminum , NLX2000

    I've never used an external rotary broach but I assume it's similar to the internal style. If I remember right it sits at a 1.5 degree angle so you must dial it in while extending out a specific distance. Are you dialing in off of the spline itself?

    Calculating SFM with a smart phone

    Hey guys. It's been 5 months since I've posted about the Machinist Calculator App that I've been working on. A few weeks ago I made some big changes to the SFM calculator and wanted to share it with you. You can now find SFM based on material type, material hardness, cutter type, & machining...

    CNC honing

    I'm definitely not an expert in burnishing, but the little I have done required the bore diameter to be held closer than +/-.001". So far I haven't been able to hold any tighter than that. Are they reaming first?

    CNC honing

    Rene41 does not like to be burnished or machined for that matter. I can't hold a close enough tolerance boring the hole. It's diameter to length ration is too high. Rene41 is a nickel alloy with 19% chrome, 10% molybdenum, & 10% cobalt.

    CNC honing

    Has anyone on here had any experience honing on a CNC? I found a company online called Bates Technologies that looks pretty cool. I have a production part made out of Rene 41 with a Ø.7500" +/-.0002 blind bore that's roughly 4.5" deep. It has a .170 wide relief at the bottom. This part takes way...
