Results of a study into the possibility of the application of special tools for microgrinding on a single-disc lapping machine are presented in the paper. One of the tools has a layer of electroplated diamond grains (grit size 63 µm or 53 µm) and another consists of multiple abrasive discs (grit size 3 µm or 2 µm).
micromilling and microgrinding. Microgrinding is used after micromilling, as a rule, to eliminate the defects impermissible in high-preci-sion components [1–3]. In Fig. 2, we show an exam-ple of such defects (burring). It is difficult to use microgrinding after micromill-ing because the small size of the part significantly
Applying these setups, we are able to produce ultra-small micro grinding and micro milling tools with typical diameters of 50 µm and down to 4 µm. However, the …
