Centerless grinding processes are often highly developed series processes for the economically efficient machining of rotationally symmetrical components, such as piston rods, jet needles, gas pressurised springs, needle rollers, crankshafts, camshafts and valves.

The workrest blade for supporting components during the grinding process is one of the most important wearing components on the machine, and this plays a large role in determining the dimensional and shape accuracy as well as the surface quality of the component. The low friction of diamond compared to steel reduces the machining forces and therefore improves the quality of the work pieces. Often, PCD can do even more than this: the polished PCD surface smoothes down the workpiece surface and reduces roughness.

To achieve optimum results over a long period, there is no real alternative to PCD coatings
