Does anybody know how I can apply diamond abrasive grit to metal bits, wheels, etc. ?
I know some are plated & some a glued, but I don't know how to do either. I see cheap diamond abrasives on Alibaba, but asking the Chinese how to use them is next to impossible. I've been using a diamond product made by Scomac that is in the form of thin copper sheet imbedded with diamond grit; the copper is easily cut and glued onto bits. It is relatively affordable and works pretty well, but the copper strips can break loose. I recently bought a new supply of the copper/diamond and recoated a bit, but it's stopped grinding and I'm wondering if I got a bad batch. I really wish I knew how to apply the diamond grit directly onto my bits.
The bits are relatively large and made of steel. They are a tapered cone shape, about the diameter of a soda can, that I used to countersink my blown glass sinks.
I wonder if I can braze the diamonds on? The bit is has quite a bit on mass (think of a solid steel hockey puck), so it would take a long time to cool and I don't know how to keep the grit in place while it cools. Maybe that isn't an issue? I guess I could test the process on a horizontal piece of flat steel plate, using a cheaper grit than diamond.
Any ideas or tips?
