Examples of applications:

Axial Forming

77


• tight tolerances – very small pitch errors axial forming of splines possible also on thin walled tubular components

• excellent surface quality, little roughness• block teeth and missing teeth possible• short cycle times (for example 5 seconds)• low tooling costs / high tooling performance (approx. 50.000 pcs. and

greater)• cold formed part / possibility of taking advantage of hardness increase• homogenous internal stress distribution / little deformation during heat

treatment
