Abstract

A novel conditioning routine of metallic bonded diamond grinding worms is reported. The competitive manufacturing time is realized by a combination of orthogonal and quasi-tangential laser processes. The introduced quasi-tangential process is only limited by the maximum available laser power of 100W at 10 ps and 800 kHz for roughing. Hence, a maximal ablation rate of 55mm³ min^-1 is reported and the accumulated ablation rate for conditioning is 3mm³ min^-1. Following, the manufacturing of grinding tools within a maximal geometric deviation of 40 μm is shown. The threaded tool is finished by a laser sharpening process exposing the bonded diamonds on the surface for increased cutting characteristics. Thermally induced phase transitions are assessed via Raman spectroscopy and reveal a negligible heat-affected zone.
