For gear grinding we differentiate between two types - discontinuous profile grinding and continuous generating grinding:

Continuous generating grinding

For continuous generating grinding all tooth flanks of the workpiece are machined simultaneously during one stroke of the helical tool. This is accomplished with a synchronised constant rotation of the workpiece relative to the grinding tool. Due to the kinematics of this process, indexing and positioning times are greatly reduced, resulting in low cycle times. Therefore, it is a highly productive and cost-effective gear grinding process well suited for small and medium-sized gears. Both, dressable ceramic tools and non-dressable CBN tools can be used (in cylindrical or globoid design).

Discontinous profile grinding

Profile grinding of gears describes a process in which the tooth flanks are machined gap after gap with single or multi-ribbed profiled tools. This process offers the highest flexibility while still achieving optimum quality. Discontinuous profile gear grinding is mostly utilised for small batch series and prototype manufacturing. Dressable ceramic wheels as well as non-dressable CBN tools can be used for this grinding process.

KAPP NILES provides a wide spectrum of machine models suited to the processes of profile and generating grinding.

All machines of the KNG series are equipped with the innovative KN grind user interface. This allows intuitive parameterisation of the machining task. The user is guided and supported when entering the workpiece and technology data. A flexible machining sequence is then defined via a sequence control. The user can view and influence the status of the machining process at any time.
