Precision Machined Round Flanges
Weforging specializes in manufacturing CNC machined round flanges that deliver exceptional strength, precision, and long-term reliability.Each flange is made through precision forging and CNC machining, ensuring refined grain structure, high material density, and excellent surface finish. These flanges are ideal for industrial, automotive, and marine applications, where stability, sealing, and dimensional accuracy are essential.
Forging and CNC Machining Process
Each round flange starts with high-quality carbon steel or alloy steel, precisely cut and heated for optimal plasticity. Under controlled pressure, the metal is forged to refine grain flow and enhance density. This process enhances density and forms a strong, stable structure. The forged blank is then heat-treated—through normalizing, quenching, and tempering—to achieve the right balance of hardness and toughness. During CNC machining, multi-axis lathes and milling centers produce accurate bolt holes, sealing faces, and smooth concentric geometry. Critical surfaces are polished to achieve fine finishes and dimensional precision. Finally, each flange undergoes CMM and ultrasonic inspection for quality. These steps ensure ISO-certified performance and long-term reliability in use.
Benefits of CNC Machining for Flanges
CNC machining provides exceptional accuracy and consistency for every forged flange.With computer-controlled tools, it maintains tight tolerances, smooth surfaces, and precise bolt alignment.This advanced process enhances sealing accuracy, improves assembly efficiency, and supports consistent production results.Furthermore, CNC technology enables complex geometries, making it ideal for high-performance flanges used in industrial and marine systems.When integrated with forging, it enhances both structural strength and dimensional stability. It’s ensuring dependable performance throughout the product’s service life.
