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.
