CNC Rubber
CNC Rubber is a class of elastic materials commonly used in applications requiring high elasticity, compression resistance and shock absorption. Compared with metal and engineering plastics, rubber has excellent softness, wear resistance, sealing and fatigue resistance. When CNC machining rubber materials, special attention needs to be paid to their softness and elastic characteristics to ensure cutting accuracy and performance.

Why Rubber Make Sense for CNC Machining
Excellent elasticity and flexibility
Rubber materials can deform and recover repeatedly, making them suitable for seals, gaskets, cushions, and vibration-damping parts.
Good sealing performance
Rubber conforms well to mating surfaces and helps prevent leakage of air, water, oil, or other fluids.
Shock and vibration absorption
Rubber absorbs impact and vibration effectively, helping protect equipment and improve noise reduction.
Material options for different environments
Different rubber types such as silicone, EPDM, NBR, and Viton can be selected for heat, oil, weather, or chemical resistance.
