Operating a Zhongrui CNC press brake requires systematic training and adherence to safety protocols. Start by installing the appropriate tooling (punch and die) using the quick-clamping system, ensuring proper alignment. Program the CNC system by inputting part dimensions, bend angles, and sequences via the touchscreen interface, or import designs from CAD software. Adjust the backgauge to position the material accurately, and set the bending force and speed based on material type and thickness. Perform a trial bend on scrap material to verify dimensions, using the built-in angle measurement system to make adjustments. During production, monitor the process for any deviations and use safety features like light curtains to prevent accidents. After operation, clean the machine, inspect tooling for wear, and store parameters for future jobs to streamline repeat production.
