Temperature Compensation : Modern Machine Shop

Temperature stratification within a room may create temperature differences between components placed near the floor, and components placed on a high shelf. The relative masses of the components may make a difference. For example, an engine block may take longer to reach equilibrium with ambient temperature than a bore gage.

Ground coffee temperature - Grinders - home-barista

Like I mentioned above, the ground coffee temperature till a certain range doesn't have a negative impact on taste, just because people or some manufacturer repeating these things again and again, doesn't make it true. You will get this "burned" ground coffee from some blade grinders or some 100 grinders for sure, but that is another story.

How Temperature Affect Grinding Efficiency

The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects. The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached. The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1.
