"Combining CNC Machining and 3D Printing" is a machining technique that combines the advantages of traditional metal 3D printing and CNC machining processes to achieve more efficient and precise fabrication. While metal printing can achieve high accuracy manufacturing, it may not meet the requirements for certain complex parts. By integrating CNC machining, not only can the cost of metal parts be significantly reduced, but production speed can also be increased by over 80%. This approach offers high flexibility, efficiency, and cost-effectiveness, improves accuracy and quality, and meets the demands of advanced manufacturing requirements.
CNC machining, the fundamental principle of which involves using computer-controlled machine tools, enables cutting, drilling, and other operations by controlling the movement and positioning of the tool and workpiece based on programmed instructions. On the other hand, 3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects layer by layer. Unlike subtractive manufacturing, which involves cutting products from larger material blocks, 3D printing minimizes material waste.
The application of "Combining Machining" is suitable for certain special parts with complex shapes and precision requirements that traditional metal printing alone cannot fulfill. By integrating CNC machining, high-precision and high-efficiency fabrication can be achieved, meeting the quality requirements of the product.
Key technical requirements include:
Dimensional accuracy: CNC machining requires micron-level precision to ensure the dimensional accuracy of the parts, often involving multiple cutting processes to achieve the desired precision.
Surface quality: CNC machining can achieve high-precision surface finishing, ensuring the quality of the part's surface.
Processing speed: CNC machining can enhance production efficiency by controlling the speed and depth of the machine tool, ensuring the product's production cycle.
Case analysis:
Fine parts, which require strict control over accuracy and quality, may not meet the requirements solely through 3D printing. Therefore, the use of CNC machining is necessary to enhance the part's safety and effectiveness. Architectural models, on the other hand, are popular art pieces that can be achieved using CNC machining alone to create complex and delicate appearances and structures. However, the cost can be high, so combining technologies like 3D printing is recommended to reduce costs.
In summary, by utilizing the combination of machining techniques, the strengths of traditional metal 3D printing and CNC machining can be fully utilized. Different processes can be flexibly combined according to specific needs, making the production process more versatile and efficient.
