Well let us know how it works.

Hopefully they figure it out with the manuals sent. So far no joy I guess.

Think I found something on it.

I don't read Chinese (or patent language), but the drawings (more after page 34 in second patent document listed) are helpful. There are clearly some similar concepts, but these show a flat sharpening platten / surface, versus a round one, and a gear driven grinding head, versus a gravity fed one.

This patent may have been a precursor in the development? But compare those drawings to the cut away photos and IPLs in the Temco thread.

Thanks.

For those interested, that link is to a thread on a similar (identical?) auto grinder that I had he chance to evaluate almost a year ago. Includes IPL, 'cut-away' photographs of the innards, and my impressions as a user.
