When one thinks of CNC machining, materials like aluminum and steel typically come to mind. However, the precision and versatility of Computer Numerical Control (CNC) technology extend powerfully into the realm of polymers, specifically rubber and elastomers. For industries ranging from aerospace and automotive to medical devices and consumer electronics, the ability to precisely machine these flexible materials is critical for creating highperformance seals, gaskets, dampers, and custom components. For businesses seeking a reliable partner for custom parts, understanding this specialized process is key.

Their inherent flexibility and low melting points can lead to deformation, poor surface finish, and tool clogging if not handled with expertise. Successfully CNC machining these materials requires a deep understanding of their properties and the implementation of specialized techniques. This includes using extremely sharp, specially ground tools, often with high rake angles, to achieve a clean shearing action rather than tearing the material. Optimizing cutting speeds and feed rates is also crucial; high speeds with slow feeds help prevent heat buildup and melting, while effective chip removal (often using compressed air instead of coolant) prevents the material from adhering to the cutter.
The advantages of CNC machining for rubber and elastomers are substantial. While molding is excellent for highvolume identical parts, CNC machining is the superior solution for prototyping, low to medium production runs, and parts with complex geometries that are impossible to achieve with a mold. It allows for rapid design iterations without the cost and lead time of creating new molds. Furthermore, CNC machining can process a wide array of elastomers, including Nitrile (BunaN), Viton® (FKM), Silicone, EPDM, and Neoprene, enabling the selection of a material with the perfect combination of chemical resistance, temperature tolerance, and durometer (hardness) for the application.
