When Cold Forming Threads Makes Sense Modern Machine Shop

Oct 09, 2007 Tapping via cold forming is appropriate for materials with tensile strength less than 1,200 N/mm2 and fracture strain of 5 percent. As a rule of thumb, if a continuous chip is created when drilling, then the material is likely a good candidate for cold forming the threads. However, suitable materials react to cold forming in different ways.

Don’t Cut Threads — Form ‘Em

Mar 25, 2021 Cold forming technology has been used to produce threads for more than 100 years. Tap designs have changed considerably in that time, and speeds up to 260 sfm (79 m/min) are possible with coated taps, according to Emuge Corp. (Northborough, MA).

Making Micro Threads Production Machining

Apr 19, 2013 Cold formed threads are stronger than cut threads. Forming forces can be significantly lower than in cutting. Thread blank diameter is very important for correct rolled threads. A 2.4-micron (0.0001 inch) increase in blank diameter increases thread form by 10.1 microns (0.0004 inch). Both thread form and size can be varied by varying part blank
