External cylindrical grinding machine KNG 5P expert

internal cylindricalfor gearswith rotary table

Product overview
The KNG 5P expert is a gear grinding machine designed for precision machining of external and internal gears. The compact machine concept combines efficient setup with flexible production capability. The direct-driven grinding spindle accepts grinding wheels from 60 to 350 mm diameter and runs up to 9,500 rpm. The dressing spindle swivels to an ergonomically accessible position for quick tool changes. Five-axis interpolation via an open swivelling axis enables efficient, nearly twist-free double‑flank grinding. A generously dimensioned rotary table with electric direct drive and deep bore accommodates long shafts. A wide range of configurable options allows adaptation to varied applications.
