Honing, Lapping, and Superfinishing Grinding Services

Honing is a finishing process used to improve the geometry of a part, readjust the alignment of features such as holes or bores, and produce a finer surface finish. In the honing process, a small, bonded, abrasive stone or super-abrasive stick is rotated over the surface of a part over a controlled path.
