Influencing factors
Factors affecting quality
and process reliability during knurling
Numerous factors must be taken into account and optimised in order to
manufacture a high-quality and functional knurling profile.
The factors listed below are crucial for process reliability, quality,
precision and surface quality and should be taken into account in
order to optimise the application.
