How It Works – Precision Thread Rolling | Today's ...

Thread rolling is primarily a cold forming process done at room temperature, but a niche does exist for hot rolling when materials are greater than Rockwell C 45, because die life would be seriously compromised. Like centerless grinding, its sister process, the thread rolling process can be infeed or thrufeed. Thread rolling is the method of choice for highvolume production threading ...

Roller Mill Maintenance00

Operating out of tram or parallel and trying to make a fine grind or thin flakes may cause the "close" end (or center of the rolls if out of tram) to actually make metal to metal contact. If the roller mill is operated with the rolls out of tram or out of parallel, significant thrust loads may be exerted on the rolls .
