    Practical way to true a Diamond grinder wheel?

    I think crossing over a soft material Moblyb, mild steel, or brass with .002down feedsd would put a dome/ a convex bottom to the wheel...down feeding one or two tenths might be ok so just taking the wheel where it was one or two tenths high. A diamond on an AO dresses flat..and a brake wheel...

    Okamoto service engineer- ask me anything

    QT: As eKretz said earlier, the OP hasn't been posting since late 2017, so you're unlikely to get a response from him. Better would have been for the OP to post "grinder expert to answer grinder questions." Likely the OP found that thatposting a lot of Okamoto problems was making the Okamoto...

    Okamoto service engineer- ask me anything

    Alan Warner said: OK. so, whyy won't Okamoto sell me spindle for my 6-18 linear/ newbe crashed cause he forgot the mag and raked the dresser block into the wheel. long /short, the taper mount runs out .0005 at the extreme small end. This is a hack method..but I have indicated a run-out spindle...

    What kind of tip to indicate vitrified aluminum oxide abrasive?

    QT OP: But I need to measure a number of wheels and blocks when they're off a machine for QA purposes. Then the tape idea, or perhaps a sealed ceramic bearing, might be the ticket...

    What kind of tip to indicate vitrified aluminum oxide abrasive?

    QT OP (original poster): I used copper foil shaped into a sort of cup and held above a test indicator contact tip with some sticky tape. It was ok, but it got about 2 thou thinner with each rotation of the wheel being measured. Copper is likely the worst material to consider using. I have never...

    Smithy at300 dead center

    If you can measure the hole likely, you can tell what taper it is. MT #2 would be a little smaller than 3/4" https://littlemachineshop.com/reference/tapers.php

    Spindle rotation direction opposite to carriage lever on new lathe.can this be right?

    A darn shame that machines don't have standard controls. Good that one checks with the manufacturer because a miss wired machine can travel the wrong way to not safely stop going in the wrong direction, and so break the machine. for odd machines, it is good to add a direction pointer/sign.

    Practical way to true a Diamond grinder wheel?

    I hack-dress a diamond wheel coming down on a piece of brass or steel to only grind /dress on the high place of the wheel with down feed..if hack cross-travel dressing, I will come down .0002 or so to just hit/take wheel from the high place. I think the molybdenum method would be best served...

    General advice on using reamers

    End sharpening a reamer is best done with the but end on a dead center and the cutting end in a bushing, or held between two dead centers. Holding a reamer in a collet or a chuck for sharpening is a poor method. Generally, 8 to 12* is a good primary clearance, and more for aluminum. Perhaps 10...

    reducing OD of a glass lens on a cylindrical grinder

    OT: Here is another failure in grinder use instruction. https://openoregon.pressbooks.pub/manufacturingprocesses45/chapter/chapter-5-surface-grinder/ Very important is " always look at the wheel specs (printed on the wheel blotter) to see that the wheel RPM is at or lower than the spindle." I...

    What kind of tip to indicate vitrified aluminum oxide abrasive?

    Name brand AO wheels run very true/close Od to ID. The wheel hole needs to be made a few thousandths larger than the mount/adaptor so it can go on. Indicating diamond wheels is common but indicating AQ wheels is not common because diamond dressing is so much faster and more accurate than...

    reducing OD of a glass lens on a cylindrical grinder

    I'm pretty sure Amazon ships to Germany This may be an OK wheel running wet. https://www.amazon.com/Diamond-Grinding-Concentration-Carbide-Tungsten/dp/B07VJ1C4W6/ref=sr_1_30?crid=3K66ATASC1YIU&keywords=diamond+grinding+wheel&qid=1685099655&sprefix=diamond+grinding+wheel%2Caps%2C147&sr=8-30

    Can the Precision Matthews PM-728VT CNC kit able to do micro machining?

    Only if you thought you could make the $50 parts that likely cost $25 to make for $12 bucks.then you could make some money..but it is likely it is a $100k special machine doing the making, not a $4,000 bench machine...so it will likely take $300 worth of time to make the part you can sell for 50...

    General advice on using reamers

    Reamers usually ream .0002 over the micrometer size, but some can be difficult to measure because one may measure not exactly straight across at exactly 180* We used to have a fussy reamer manufacturer leave a portion of the web (area between the flues) intact to have a better place to measure...
