All About Thread Grinding - Precision Tools and Gage …

As far as lead is concerned, some thread grinding machine manufacturers guarantee to hold the lead within 0.0001 inch per inch (or mm per mm) of thread; and while it is not guaranteed that a higher degree of accuracy for lead is obtainable, it is known that threads have been ground to closer tolerances than this on the lead.

The Engineer's Guide to Identifying Lead Screw Thread Forms

Thread Form Terms Pitch – The axial distance between threads. Pitch is equal to the lead in a single start screw. Lead – The axial distance the nut advances in one revolution of the screw. The lead is equal to the pitch times the number of starts. Screw Starts – The number of independent threads on the screw shaft; example one, two or four in the

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 in-feed or thru-feed.

The Fundamentals of Thread Rolling

Thread rolling makes use of hardened steel cylindrical dies to shape materials; the dies, imprinted with the thread profile, penetrate the work metal at ultra-high pressures in order to displace and mold it into a mirror-image thread. Unlike traditional cutting and grinding methods, no metal is lost or cut away during the thread rolling process ...
