Thread grinding

The thread grinding process is generally used in the manufacture of thread cutting tools for internal threads. Thread rolling dies for external threads require higher profile accuracy today and are therefore frequently machined by grinding.

Due to the extremely high requirements for profile retention, vitrified bonded grinding wheels are almost exclusively used in this grinding process. Either aluminium oxide or silicon carbide are used as the abrasive grain depending on the material.

Selection of the suitable grit size mainly depends on the pitch and profile radius of the thread being machined. The smaller these are, the finer the grain that is to be selected. Grit sizes here range between 150 and 500.
