Dawopu Group is the specialist provider of honing and super finishing services.
Honing is the process used to finish round bores using abrasive stones to achieve close tolerances, excellent surface finishes & improved geometry. Specialist tubing is often only available in a standard range of sizes & so it is necessary to use honing to produce non-standard sizes & finishes.
