CNC Stainless Steel Preision Bushing
Dongguan Changxinda Precision Technology Co., Ltd. is a leading CNC machining expert specializing in high-precision turned components for industrial automation, mechanical engineering, and equipment manufacturing applications. With 18+ years of manufacturing experience, the company has established itself as a trusted partner for precision component manufacturers, automation system integrators, and industrial equipment producers worldwide. This stainless steel precision bushing exemplifies the precision engineering and manufacturing excellence that defines Changxinda's capabilities, delivering a high-quality cylindrical component for demanding industrial applications.
The precision stainless steel bushing is a cylindrical turned component featuring a precision-machined through-bore and a distinctive knurled outer surface pattern. The knurled exterior provides enhanced grip for manual installation, adjustment, and removal operations, making the component ideal for applications requiring frequent handling or adjustment. The knurling pattern is precisely cut using specialized lathe tooling, ensuring uniform depth, spacing, and sharpness across the entire grip surface. The interior bore is precision-bored to tight tolerances, providing accurate dimensions for shaft fit, bearing installation, or component alignment in assembled mechanisms.
Manufactured using advanced CNC lathe machining technology, this bushing achieves exceptional precision and surface finish quality. The CNC lathe enables single-setup production of all features including the outer cylindrical surface, knurling pattern, end faces, and internal bore, ensuring perfect concentricity and dimensional accuracy throughout. The turning process achieves tight tolerances of +/-0.01mm on critical dimensions including the bore diameter, outer diameter, and overall length. Surface finishes on the bore and outer diameter are controlled to provide smooth, accurate contact surfaces suitable for precision assembly operations.
Stainless steel construction provides excellent corrosion resistance, high mechanical strength, and good wear characteristics for long service life in demanding environments. The material selection makes this bushing suitable for applications exposed to moisture, chemicals, temperature variations, and mechanical stress. Common stainless steel grades used for similar applications include 303 for free-machining characteristics, 304 for general corrosion resistance, and 316 for enhanced corrosion resistance in marine or chemical environments. The material also provides good thermal stability for applications involving temperature variations and maintains dimensional accuracy under mechanical loading.
The precision manufacturing process supports a wide range of sizes and configurations to meet specific application requirements. Standard configurations include various bore diameters, outer diameters, lengths, and knurling patterns. Custom features such as additional through-holes, slots, threads, or specialized end profiles can be incorporated based on customer specifications. The CNC lathe production system enables rapid prototyping and efficient transition to volume production, supporting both development programs and ongoing manufacturing requirements. The component is suitable for applications including mechanical assemblies, adjustment mechanisms, control devices, and various industrial equipment.
