sharpening burr blades

[seankohmescher]

Any suggestions on sharpening burr blades: mazzer, ditting, etc.

Has anyone had any luck using a high speed grinding wheel?

I've never heard of anyone doing that - I think it would be so incredibly time consuming as to not be worth it - not to mention that results would be likely to be inaccurate unless you have special equipment. Ditting has a price competitive trade program for used burrs. Send them your Ditting burrs and if the set you send in is in a condition such that they can still be sharpened then they will send you a reconditioned/resharpened set in return (not the same set but for the same model). I've sent in some fairly worn 804 burrs a few times and always got a nice sharpened set back in return within a week or two.

You can purchase replacement burrs so inexpensively for most common machines as to make resharpening inefficient. You can get Mazzer burrs for as little as $20 or $30 dollars. Possibly Titanium burrs it may make sense or very expensive sets.

I neglected to mention that there is of course a charge for the Ditting burr trade-in program but IIRC it's about 13/ to 1/2 the cost of brand new burrs.

Jack makes a good point about new Mazzer burrs. These days, depending on the source, Super Jolly burrs seem to be mostly in the $35 to $50 range and Major burrs are in the $50 to $75 range. The conical burrs for the Robur and Kony are about 3X the price of major burrs but will grind about 3X the number of pounds of beans before needing replacement.
