Custom 440C Stainless Steel Precision Medical Shaft CNC Machining

Custom 440C Stainless Steel Precision Medical Shaft CNC Machining This precision machined shaft is manufactured from premium AISI 440C stainless steel, specifically designed for high-performance medical and precision equipment applications. Combining CNC turning, milling, reaming, heat treatment, and precision grinding, the component achieves exceptional dimensional accuracy, wear resistance, and surface quality required by demanding OEM customers. Unlike conventional machined shafts, this component requires multiple critical manufacturing processes after heat treatment. The outside diameter is finish ground after hardening to achieve tight dimensional tolerance and excellent cylindricity, ensuring stable performance in precision assemblies. The part is heat treated to 53–58 HRC, providing superior hardness and wear resistance while maintaining dimensional stability during long-term operation. Precision reamed holes, milled slots, and geometric tolerances are carefully controlled using advanced CNC machining centers and precision inspection equipment. Every production batch undergoes complete dimensional inspection before shipment. Material certificates, inspection reports, and RoHS compliance documentation are available upon customer request.
