Application of Ultra-Small Micro Grinding and Micro Milling …
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 .

This minimizes load on the square edged cutter. We're all familiar with how a radius on the edge of a square endmill (often called a bullnose cutter) can increase tool life. This is the micromachining analog. At micro-scale, you need the much bigger radius of a ballnose to make a difference. 12. CADCAM Considerations for Micro-Milling

Scale-up of micro- and milli-reactors: An overview of strategies
The aim of this review is to summarize the strategies, engineering principles and recent development for the scale-up of MRs. Generally, the volume of a MR can be expressed as (1) V = π 4 ∙ N ∙ L ∙ D 2 where N is the number of the channels connected in parallel, L is the length of the channel and D is the hydrodynamic channel diameter. Consequently, the scale-up …
