Wood grain and sawing techniques. Grain patterns can influence the way wood behaves as it adjusts moisture content. Wood that's cut from the heart of the tree is generally more stable against shrinking and warping. Very straight grain with only 1/32 in (about 0.79 mm) between grain lines is less likely to warp, regardless of wood species.

Impact Mills (Micronizer) Impact mills are high-speed grinders that produce fine flours used for cakes, pastries, and bread. Due to the high speed of impact mills, you'll only find electric versions. Rather than two grinding plates grains are ground down by two steel plates that have rings of teeth on them.
