Roll Form Taps
Chip-less manufacturing by thread forming
Depending on the application in question, we offer the following cutting materials: HSS-E, powder metal and solid carbide.
Roll Form Taps with carbide strips
The combination of elastic tool body and hard carbide strips produce a high degree of bending strength and wear resistance in the tool. This produces extremely long tool life and economic results.
Compared to tapping, no chips are produced when doing roll form tapping.
Materials with an elongation of >5% and a tensile strength of <1000N/m2
are suitable for thread forming.
Formed threads have a smoother surface and are stronger under dynamic stress than those that are cut.
Solid carbide roll form taps achieve a tool life up to 20 times longer than those in HSS-E.
Patented thread forming tools in HSS-E with brazed carbide strips are particularly suited to use on transfer lines. The flexible tool body compensates for small alignment errors while the carbide produces maximum durability in the working area.
Restrictions: thin-walled components with a wall thickness <2x pitch are not suitable for thread forming.
