The
thread rolling process produces results far superior to those
of traditional "cut" threads,as the thread rolls
used are optically ground and "cold form" the thread
on to a pre-machined blank, producing a thread of perfect
form, pitch and accuracy - within microns - whilst eliminating
weak spots and stress points - the burrs and toolmarks usually
found on a cut thread.
Certain
materials have the characteristic of work hardening when being
rolled - resulting in threads of greater strength and wear
resistance. Virtually all materials can be rolled, including
stainless steel, nimonics, titanium and heat treated steels.
