Formation Mechanism of Grain Cutting Edges in Micro

This paper presents a mechanism for the formation of grain cutting edges in the micro dressing of coarse-grain polycrystalline cubic boron nitrite (cBN) grinding wheels using a fine-grain diamond dresser. Many grain cutting edges having a flat surface consisting of ductile smooth surfaces as well as many brittle micro dents are formed on the working surface of the coarse-grain (#80 mesh) cBN

A good starter size is the 150 mm (6") mirror. A 200mm (8") will also work. Most ATM books and websites recommend a Pyrex® mirror blank but in my opinion annealed plate glass is better for this first "learn and practice" mirror is cheaper it is softer and grinds faster needing less abrasives and with these small sizes the low expansion glass like Pyrex has no practical (visible at
