This monograph focuses on abrasive tools for grinding, polishing, honing, and lapping operations. The book describes the life cycle of abrasive tools from raw material processing of abrasive grits and bonding, manufacturing of monolithic or multi-layered tools, tool use
1/1/2015· Blocky diamond grades with low grinding wheel wear should be considered where rigid machine systems are used, contact length engagement is small, and sufficient coolant/lubricant can be applied. Together with suitable bonds, the conditions then may be such that damage-free workpiece surfaces can be achieved only with blocky, high-impact-strength grit types  .
Waste silicon carbide (waste SiC) filled high-density polyethylene (HDPE) with and without surface modifiers were studied. Two types of surface modifiers namely; high-density polyethylene-grafted-maleic anhydride (HDPE-g-MA) and 3-aminopropyltriethoxysilane have been used in this study.
