It gives a general indication of the hardness and grit size of any wheel as compared with another. Coding of a grinding wheel consists of six symbols as described below
Cutting, grinding and finishing applications is a balance of numerous factors like choosing the right product and methods. There are various ways and means to select such right choices that help us in looking beyond the specific application and considering a bigger picture.
Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by …

Introduction [] Grinds vs. carousels vs. conversions []. For the purposes of this guide, a grind is a single repeatable action that reliably gives decent quantities of the expected item at little or no cost (besides actions). Grinds tend to generate lower-tier items, like Shards of Glim and Primordial Shrieks.
Grinding is a combination of rubbing, ploughing and cutting (actual chip formation with contribution of each being highly governed by grit geometry, work material characteristics, grinding loop stiffness and the grinding velocity The various stages of grinding and grinding force with grit depth of cut is shown in Figure 6.
