Each MSF machine is equipped with a nozzle cleaning and calibration station. It has three functions: cleaning the nozzle of the laser cutting head, a camera for checking the status of the nozzle, and calibration of the capacitive height sensor.
In order to clean the spatters of the laser cutting head nozzle after punching, the cutting head will automatically perform a nozzle cleaning cycle after the programmed number of punches, and, if necessary, clean it at the request of the operator. After the nozzle is automatically cleaned, the machine will automatically continue its cutting process. The calibration of the capacitive height sensor can be performed automatically after each cleaning cycle, or according to the requirements of the operator. The cutting head positions itself above the small disk and moves down to contact it. Then, it performs the measurement and linearization of the voltage/distance curve in the capacitive sensor electronics.
The nozzle camera is used to check the status of the nozzle. After placing it on top of the camera, the enlarged picture of the nozzle will be displayed on the LCD of the MMI console. The operator then decides whether the nozzle needs to be replaced or another cleaning cycle is required.
