AB-GRAPH provides a comprehensive processing system for angle bars by combining automatic programs with an NC processing machine.


  • 3D strip steel materials can be accurately marked or cut in accordance with their warpage and curves.
  • The device can make inverse line markings and circular markings around web faces.
  • Stiffeners (various angle steels, flat steels, and valve plates) can be NC processed with high accuracy and high quality.
  • A free clamp inclination table (patent) is adopted to achieve high precision and high productivity.
  • The system can be used in conjunction with an air sensor or laser sensor.
