Mechanical Disruption Methods: Grinding
To grind, hold the pestle with a gloved hand (use a protective glove) and firmly press on the sample while twisting. The sample will typically shatter into small pieces, some of which may fly from the mortar so use added caution with biohazardous materials.
The Best Games With The Most Grinding
You can't enjoy Minecraft without grinding, the two go hand in hand. Even with the smartest and most intuitive Redstone inventions, the entire premise of the game is to harvest resources.Whether that's digging long tunnels for diamonds or sitting completely still at the base of a mob farm, you won't be able to defeat the Ender Dragon without putting the hours in.
What's The Best Way To Grind Beef? | The Burger Lab
Grinding Tips: To minimize smearing, cut meat into 1- to 2-inch chunks and place them in a single layer on a sheet tray or large plate in the freezer for about fifteen minutes before grinding. Grind in batches no larger than a half pound for a 10-cup food processor. Pulse rather than constantly running the grinder to get a more even grind.
Mechanical Disruption Methods: Grinding
In single-step disruption experiments, conical glass homogenizers liberate about half as much enzyme as compared to larger more expensive high throughput homogenizers. Glass tissue grinders are approximately 30-40% as efficient as the best methods (see Fig. 20), but the relative cost is fractional ($70 vs. $15,000).

You have to make a tool anyway, and you MAYBE skipped one grade of grinding. Working by hand, hogging a 6" f/4.0 mirror and getting to radius is maybe 30 minutes of work, 40 tops. So you would be done with #80 hand grinding and have your curve before you even produce your g-code, let alone solve your work-holding problems and cooling problems.
