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 ...
Centerless Grinding for Micro Metal Parts & Stainless Tubing
Centerless Grinding. Centerless Grinding is so named because it removes material without the use of a spindle. Centerless grinding is accomplished by placing the tubing or rod on a work rest that positions it between a regulating wheel that spins the stock in one direction, and a grinding wheel that spins in the opposite direction.

It is concluded that vitrified bond diamond wheels are the most …
Metallographic Grinding: Grinders & Consumables :: QATM
The aim of metallographic planar grinding is to remove roughness from the metallographic cutting process and to achieve flatness of the ground surfaces. The abrasive itself depends on the material to be ground. For soft materials, this is essentially silicon carbide (SiC) as paper, foil, disc or stone.For harder materials ( 300 HV, e. g. hardened steel or ceramics), diamond discs are however used.
