In all seriousness tho, thats a crazy amount of work to produce burrs in house, let alone on top of making all the parts and grinders in house. Must take alot of coffee and caffeine to keep up
crazy that 2nm is enough to mount the blank and later the burr. One would think that grinding vibration would loosen that screw in a heartbeat if no locktide is use.
Would be interested see how mass production decent quality burrs like the ode gen 2 get made in China. This super high end is cool to watch. But how to get it down to $80 retail would be fascinating. Doubt they’d be nearly as open about their process.
Good question. A few differences come to mind right away such as the steel used. Kafatek uses a surgical stainless steel, he shows its a solid extruded bar that is cut to size, I'd bet the cheap ones are just poured (cast) from a less costly or durable metal. Might not even be stainless so they could put rust in your cup. I bet that one blank in the video costs more than most cheap burr sets. Next I've seen other videos showing what is essentially an angle grinder disc make the cuts in the burr and as demonstrated in this video when they looked under a microscope, the finish was ragged and would not make uniform particles. He also mentions heat treatment and distortion which is why many people have to put shims of tinfoil under burrs to try to get them flat in inexpensive grinders. Just my 3 cents
Very cool video! Love seeing the process of burr making.
@7:50 This is why ssps taste better after seasoning. 👌
Burry good content Mr Quan

Approx 1.5 ft pounds per screw, times 3 is not insignificant
Burr good
I wonder if Denis manufactures other stuff in his workshop, I can't imagine the grinder business can turn a profit by itself on these machines
Burry burry good video

Thought of another point, the coating. That can't be cheap
burr good
Burry burry gud
I'm surprised their burrs aren't more expensive. Hopefully he's paid well
