Honing Tools Life Cycle and Sustainability of Abrasive Tools

Other than in grinding, diamond has far fewer limitations when machining steel by honing. This can be explained by the low cutting speeds, cooling and lubrication conditions in honing, which tend to suppress the reaction between diamond and workpiece materials with carbon affinity [KOPP81]. 2.3.4.2 Dressing Technology Natural diamonds of high purity are commonly used Read more

Manufacturing of Resin Bonds Life Cycle and Sustainability of Abrasive Tools

Resin bonded grinding tools are manufactured via mixing, pressing and hardening at temperatures up to 200 °C (Fig. 3.5) [COLL88]. Resins consist normally of the two main components resin and hardener. Mixing both parts results in the reactive resin material. During hardening, the resin’s viscosity rises and a duroplastic material is generated. 3.1.2.1 Mixing and Read more

Metallic Multi-layer Bonds Life Cycle and Sustainability of Abrasive Tools

Metallic bonds are either multi-layered (produced by sintering or infiltration) or single-layered (produced by electroplating or brazing) [MARI07]. They are only applied to superabrasive grits because conventional grits wear too quickly to use the bonding strength to full capacity. 1.3.1 Chemistry and Types of Metallic Bonds for Multi-layer Abrasive Tools Metallic multi-layered bondings consist of Read more

Tool Wear Mechanisms Life Cycle and Sustainability of Abrasive Tools

Abrasive machining processes themselves can be regarded as tribological systems where workpiece material and abrasive tool interact under the influence of cooling lubricant and atmosphere [MARI04]. Abrasive tools are subjected to high tem­peratures and high pressures in the active cutting zone. Consequently, tool wear occurs. Tool wear happens because of mechanical effects (vibrations and grinding Read more

Case Study on Grit Size Choice Life Cycle and Sustainability of Abrasive Tools

Grit size and grit size distribution affects tool manufacturing and tool use (see Sect. 2.8.1 “Grit Size”). Therefore, these grit characteristics provide a good case study on sustainability [LINK12c]. Grit size can be controlled by different stan­dardized methods, such as sieving and sedimentation (Sect. 2.9.1 “Grit Size Selection”). The user might want to consider the Read more
