Burr grinders use a steel mechanism that grinds coffee between a pair of abrasive surfaces. Burr grinders are further sub-divided by conical and flat burrs, with conical burrs being the most common among home brewers. Burr grinders can range in price from $50 for a low-end budget model to $1,000 for pro-level that can grind to a fine powder.

Run-out or runout is an inaccuracy of rotating mechanical systems, specifically that the tool or shaft does not rotate exactly in line with the main axis.For example; when drilling, run-out will result in a larger hole than the drill's nominal diameter due to the drill being rotated eccentrically (off axis instead of in line). In the case of bearings, run-out will cause vibration of the ...

If 75% of the particles are 10 to 100 in diameter, and 25% are 100 to 200, the relative volume is 50 cubed to 150 cubed or 125:3375 or roughly 3%. It doesn't even look like 75% of the particles are fines in your graph (that's a high end grinder) -- my collection of …
Some of the extra cost can't be avoided - faster grinders require larger burrs, and this takes a larger motor to spin them. Flat burrs tend to be less tolerant of machining differences because of how it affects axial alignment (and even high-end grinders aren't immune to these issues, pre-'14 EK43s are notoriously bad out of the box for alignment).
A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

I define a CNC machine tool's accuracy as how precisely its axes can follow intended paths to commanded end points while under load. I define its repeatability as how precisely it can duplicate commanded motions (again, under load) during multiple cycles throughout the day. These are definitions for dynamic accuracy and repeatability.

The beans were a medium roast, Mexican origin. Right now I'm using a grind setting of 240 (2.4.0 on a Kinu M47 Phoenix) with a 16g dose in a 58mm portafilter. A 1:2 pull is taking 35-40 seconds total. I would expect that a setting of 230 would be unacceptably slow and 220 would likely choke the machine.
