Re: Bonding Diamond Grit

 

开云体育

??? 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 .

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:

Will any of these work?

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.

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.
