This guide explains the six fundamental metal fabrication processes—cutting, stamping, welding, extrusion, forging, and casting—and highlights the importance of selecting the correct abrasive products for each application. From ultra-thin cutting discs and depressed-centre grinding wheels to ceramic flap discs, fibre discs, coated abrasives, and non-woven products, GC Abrasives offers solutions designed to improve cutting efficiency, surface quality, and tool life. Manufactured according to EN12413 safety standards, GC Abrasives products are widely used in automotive, construction, aerospace, shipbuilding, foundries, and general metalworking industries.

With over 20 years of industry experience, Englau Group supplies high-performance abrasive solutions for sheet metal fabrication and industrial surface treatment applications worldwide. Its product portfolio includes ceramic cutting discs, grinding wheels, flap discs, fibre discs, coated abrasives, non-woven abrasives, and wire brushes, all manufactured in accordance with the German EN 12413 safety standard. The article explores the characteristics of common sheet metal materials—including aluminum, brass, bronze, copper, carbon steel, and stainless steel—and explains how selecting the proper abrasive technology improves cutting efficiency, surface quality, and productivity. It also outlines the three major fabrication processes—cutting, forming, and joining—and recommends suitable abrasive products for each stage.

This article provides a comprehensive overview of bonded abrasives, highlighting their types, materials, and industrial applications. It explains the different forms of bonded abrasives, such as grinding wheels, stones, and sticks, and details the common abrasive grains used—including aluminum oxide, silicon carbide, garnet, tungsten carbide, and alumina-zirconia, as well as superabrasives like diamond and cubic boron nitride (CBN). The article discusses various bonding agents (vitrified, resin, rubber, shellac) and their impact on abrasive performance. It covers the importance of grit size and standards for selecting the appropriate abrasive for specific tasks. Additionally, the article examines the mounting and application methods for bonded abrasives in manufacturing, surface finishing, and tool sharpening, emphasizing their role in precision engineering and material removal processes.
