CNC complex surface machining: The cutting processing of three-dimensional curved surfaces mainly adopts imitation milling and CNC milling methods or special machining methods. Biica milling must have a prototype as a mold. Contact the prototype surface at a certain pressure. Follow us: Mechanical engineers, focusing on the machinery industry, professional, professional information sharing, serving millions of engineers in manufacturing. The motion of the imitation head is transformed into inductance, and controls the motion of the three axes of the milling machine to forming the movement of the knife head along the surface. Milling tool mostly use the ball head milling tool with imitation head radius. The emergence of numerical control technology provides a more effective method for surface processing.
