CNC (Computer Numerical Control) processing is a commonly used technique in aluminum mold making. It involves using computer-controlled machines to precisely cut and shape the aluminum material into the desired mold design. The process begins with creating a 3D model of the mold design using computer-aided design (CAD) software. This model is then converted into a set of instructions that the CNC machine can understand. Next, a block of aluminum is secured onto the CNC machine's worktable. The machine's cutting tools, such as end mills or drills, are then programmed to follow the instructions and remove excess material from the block to form the mold shape. The CNC machine can perform various operations, including milling, drilling, and engraving, to achieve the desired mold design. During the CNC processing, the machine continuously measures and adjusts its position to ensure accuracy and precision. This allows for the creation of complex and intricate mold designs with high dimensional accuracy. Once the CNC processing is complete, the aluminum mold may require additional finishing processes, such as polishing or surface treatment, to achieve the desired surface quality. Overall, CNC processing is a versatile and efficient method for aluminum mold making, enabling the production of molds with high precision and intricate details.
