The Latest from Our Experts

The critical costs involved in any manufacturing endeavor always include time, materials and overhead. Most frequently we strive to control material and tooling costs as our best solution to control product cost. Time is usually the highest cost involved in…

Fixturing a thread rolling head in a modern CNC machine can be enhanced with the addition of a fixturing flat on the shank of the tool. The present design of the modern EVO style Fette thread rolling tool can be…

Thread rolling on CNC machines unattended requires a closing scheme to reset the head after each rolling cycle. This is accomplished with a program move that will cycle the closing handle past a fixed point within the machine that will…

Technology is constantly evolving. The Ford model T eventually evolved in to the F40 and beyond. Thread rolling likewise is a constantly evolving technology. The tools themselves have become more user friendly and the rolls have improved in performance over…

It started with the wheel and later led to the telephone and electricity. Invention and discovery continue to change the face of our world as we know it. Thread rolling developed in the early twentieth century and has mostly remained…

We recently introduced a Patent Pending attachment to convert a traditional pop open threading tool to a Roll-On Roll-Off™ device. When used on modern CNC machines a closing strategy had to be engineered specific to the individual machine. To ease the…

For too many years rolling threads on metal parts was considered a “black art.” And, indeed, depending on the individual circumstances, it was. Bump rolling was a popular method used on a variety of screw machines. It required precise knowledge…

For many CNC applications thread rolling is the best choice for creating higher quality external threads in one pass without chips. The technology has spanned years on multi spindle machines, engine lathes and dedicated thread rolling machines. CNC machines can…

It started with the wheel and later led to the telephone and electricity. Invention and discovery continue to change the face of our world as we know it. Thread rolling developed in the early twentieth century and has mostly remained…

While we often extol the various attributes of cold formed (rolled) threads, the materials that can be rolled are seldom outlined in broad terms. Steels are virtually all roll-able. Included in the steel family are Structural, Case Hardening, Nitriding, Free…
