KNM P series

portable gear inspection and 3D measuring systems

machine concept
With KNM P series, KAPP NILES Metrology GmbH - manufacturer of the currently largest gear measuring machines (stationary or transportable) in the world - offers the first portable independent measuring equipment for larger gears, ring-shaped workpieces, housings etc. directly on the production machine or on the shop-floor.

The device is a new development based on well proven technologies, as well as innovations and has been perfectly adjusted to customer requirements specifically for the independent measurement of spur and helical gears or ring-shaped parts such as bearing rings and also housings etc. directly on the production machine or on the shop-floor without rotary table.

Its setup as CNC-controlled 3-axis measuring equipment permits determination of profile, lead, pitch and runout deviations on gears as well as general parts contours. Proven software for fully automatic measuring cycles is available.

The system needs to be mounted on a stable support connected to the base / foundation of the production machine.
