Micro-mills look similar but operate in a different world than conventional cutters do… Makino says micro-milling involves features smaller than about 0.001″ (what they actually say is smaller than 0.00098″).A little more common definition says it involves cutters smaller than 0.015″ in diameter and tolerances measured in tenths. Either way, these are very small numbers.

Back to Basics Hammer Milling and Jet Milling Fundamentals

A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding

Pavement milling - Wikipedia

Micro milling. Micro milling is also known as carbide grinding. It is a lower cost alternative to diamond grinding of pavement. Micro milling uses a specialty drum with three to four times as many cutting teeth than a standard milling drum. Micro milling can be used either as the final surface or as a treatment before applying a thin overlay.
