Cutting Edge Density Life Cycle and Sustainability of Abrasive Tools

Cutting edge density is important to understand tool performance during the grinding process. Many researchers analyzed the statistical nature of the cutting edges [KASS69, BUTT68, SALJ88, HOU03, LORT75, etc.]. 6.2.1 Definitions Static Cutting Edge Density Researchers differentiate between grit number and cutting edge number because each grit can have several cutting edges. However, both Read more

Grinding Process Model Life Cycle and Sustainability of Abrasive Tools Traditional Fundamental Requirements in Grinding Manufacturing processes have to accomplish certain tasks depending on workpiece material, stock removal (finishing or roughing operation), availability of machines, batch size, form and dimension tolerances, achieved surface roughness and integ­rity, and more [LINK12c]. The following discussions focus on ductile material in finishing operations and the choice of the Read more

Abrasives Life Cycle and Sustainability of Abrasive Tools

Look at this small grit, this tiny grain, so small one must rub hundreds of them between finger and thumb to feel their sharpness. Insignificant little grits and easily slighted in our sophisticated technological world, but without this small fragment of abrasive, transformed, when viewed under a microscope, into jagged heroic blocks — without these Read more

Thermal, Electric and Magnetic Properties Life Cycle and Sustainability of Abrasive Tools Effect on Tool Production High sintering temperatures over 1300 °C can occur in manufacturing of vitrified bonded tools. In particular, diamond features low thermal wear resistance in air, which forced manufacturers to develop special low-temperature sintered bonds and to apply inert atmospheres [LINK15]. Electric and magnetic properties are important for electro-plated bonds because they Read more

Adhesion Life Cycle and Sustainability of Abrasive Tools

The direct contact of body and counter body can lead to atomic bonds (“micro weldings”), which are defined as adhesion [GAHR87, RABI95]. A relative movement of the contact partners does not necessarily involve that the bonds break within the original contact areas, so that material transfer can happen [HABI80]. Adhesive layers change the friction conditions. Read more
