Actually, the stones make the carbide edges duller...the purpose is to
take the sharp edges off very evenly, making the carbide more durable
in heavy cutting operations...but i'm still inclined to agree with you
that it's a far from brilliant process. In most instances it actually
works, though.

Hello,

The shop that I work at has special order carbide inserts, and due
to
heavy feed to speed ratios on our machines, we have found it
necessary
to hone the inserts. To keep them in tolerance (.002 hone) we have
put
them in a tumbler with some stones and silicon carbide sludge...
this
method because its worked for us on lighter hones. This time
though,
the inserts are all chipping to hell! I tried putting even one
piece
at a time to fix it in case they were bumping each other, no help.

Now I am getting the blame from my boss, and whether it is somehow
my
fault or not, getting the blame is just unacceptable.

Any advice from those experienced in honing carbide??

Thanks,
Erik

So to make the fragile, easily broken pieces of carbide sharper, you
put them in a bouncing box of rocks?

This is a troll, right?
