Particularly in high gear cutting quality and a long service life can only be achieved with precisely can only be achieved with precisely adjusted cutterheads. The Oerlikon cutterhead setting and testing device CS 200 enables quick and easy setting of the individual knives and simple adjustment of the individual knives, it checks the position and documents the measurement results. The measuring sequence on the CNC-controlled testing device is partially automated: The individual actions for carrying out the actions for carrying out the sequence are displayed on the screen via the operator guidance. The positioning of the individual knives in the cutter head and the height of the knife tips is largely automatic thanks to a special sequence and is simultaneously documented by means of a run-out diagram. A subsequent measuring sequence checks the radial position of the inner and outer cutting edges of all knives in the cutterhead. If individual test parameters on the knives do not correspond to the the tolerance specifications, this can be individually repositioned. The combination of semi-automated setting sequence, operator-guided set-up actions Njdpfx Ajul Efmod Nocl and automatic operator-guided set-up actions and automatic measuring sequence, cutterheads can be can be set conveniently, quickly and with high precision. Operator-guided setting and test sequence - Graphic display of the cutter head design and the measurement results with tolerance check - Instructions for the operator in plain text Instructions for the operator in plain text (without coded information) - Simple assignment of the measurement results to the knives - Documentation of the setting and measurement results via printer- Setting and test sequence suitable for ARCON®, RSR, Spirapid, SPIRON®, TRI-AC® types - Interface for neutral data
