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.

Micro pencil grinding tools consist of a cemented carbide basic body and an abrasive body. The abrasive body consists of superabrasive grits (diamond or cubic boron nitride (cBN)) and the bond; in this case the bond is a nickel coating. Micro grinding uses much lower feed rates than micro milling, but covers harder and brittle materials .

Abstract. Interactions of wear debris at the toolworkpiece interface in microgrinding are quite random which leads to considerable variability in the working life of similar tools. It is not possible to capture the effect of wear debris entrapment on process signals using the available physicsbased model, which makes it difficult to identify the tool life stages. The present study ...
