Bonding Diamond Grit
|
This is a tangential topic at best. The question is does anyone know of a way to bond diamond grit to a steel plate? I am thinking about experimenting with general purpose epoxy. However they bond brake linings could work, but I do not know how. Regular epoxy seems like it would fail as the plate heated, but the brake lining adhesive should be more than adequate.
?
Background: I have a 1950's era grinding machine that uses steel discs with bonded diamond grit on the flat side of the disc. It would be perfect for HSS or carbide sharpening given its adjustable angle work table. The problem is that the abrasive plates are not available any more. Self-adhering sanding discs are an option, but not preferable.

I would think about the epoxy used for industrial floor coatings

The diamond plate sharpening stones are bonded by spreading the diamond grit on a piece of steel and nickel plating it to hold the diamonds bonded there.

Ebay has a lot of grinding materials for lapidary processing. All sorts of grits are available, up to about 3,000.
You can start browsing with this example and see if it is useful:

??? Yea , that was my thought hitting up a lapidary place . I
have a couple small rock saws & one has a grinding wheel on
one outboard side with a diamond wheel . I just went out &
looked? sorry no name on either the grinding wheel or the saw
blade . But their still using diamond wheels? today so I know
their out there . Ya may be able to get by using a diamond blade
with some backing & when it fizzles out just flip the blade
over to the fresh side ?
please keep us posted on what ya end up with .

Thank you for the replies. I will be researching the nickel plating
process now that I know it is done commercially. No one makes
replacement grinding plates for this machine. I have searched all of
the obvious places. Not sure when they quit making it, but it is
perfectly designed to grind lathe/shaper cutting tools. I will try
to post a picture tomorrow.

I have one of these Leonard grinder-lap machines and it is awesome.
Uses 5-inch magnet based diamond wheels, runs at about 350 rpm and has an eccentric to make it wobble a little.
Awesome for sharpening and polishing lathe tools and carbide inserts.??

You can make your own using those lapidary disc's. Cut their diameter to size and mount them on a steel disk using neodymium magnets.

That's mine. Great design. I saw the link for the replacement plates
too! $109 a plate is not awesome, but probably cheaper than making
one. Do they last? Which grits do you use? This is a great example
of being careful of how much you pay at an auction because the part
you need to get it to work could cost you a lot.

Could these engraving tool sharpening wheels be adapted to your machine? Pricey, but may save you some trouble. I do have a few if you need dimensions.
