This resource provides field-tested starting parameters for Minnexon Solid Carbide Metric Thread Mills. We designed this data to help engineers who are new to thread milling achieve reliable results immediately.
Note for Experts: All parameters are conservative and aimed at maximizing tool life and stability. Once you are familiar with your machine’s rigidity and the material’s behavior, you can optimize by slightly increasing the Vc (Cutting Speed) and fz (Feed per Tooth) for higher productivity.
