This stainless steel locating pin exemplifies the precision engineering and manufacturing excellence that defines Changxinda's capabilities, delivering a high-performance positioning component for demanding automation applications.

The stainless steel locating pin is a critical precision component used in industrial automation systems to provide accurate, repeatable positioning of workpieces, tooling, fixtures, and machine components. This precision-turned component serves as a fixed reference point that ensures consistent location of parts during assembly operations, machining processes, and automated handling sequences. The locating pin's dimensional accuracy directly impacts the repeatability and quality of manufacturing operations, making it an essential component in precision automation architecture.

Manufactured from high-grade stainless steel using advanced CNC lathe machining technology, this locating pin delivers exceptional hardness, wear resistance, and corrosion resistance essential for demanding industrial environments. The stainless steel material provides excellent mechanical properties including high strength, good toughness, and resistance to corrosion from various industrial fluids and environmental conditions. The CNC lathe machining process enables production of precise cylindrical geometry with tight diameter tolerances and excellent surface finishes, which are critical for proper fit and function in precision locating applications.

The component features a precision-machined cylindrical body with multiple diameter sections that provide the functional locating surfaces. The main locating diameter is machined to tight tolerances to ensure proper fit with corresponding bushing or hole features, providing accurate positioning without binding or excessive clearance. The stepped geometry includes a larger diameter head section for tool engagement during installation and removal, and the precision-machined transitions between diameter sections ensure smooth assembly and reliable performance.

Surface finish is carefully controlled on the locating surfaces to ensure proper fit and minimal wear during repeated insertion and removal cycles. The smooth machined surface reduces friction during assembly operations and provides consistent contact with mating components. Optional features such as chamfered ends facilitate easy insertion into mating holes, reducing the risk of damage to either the pin or the mating component during assembly operations. The high-grade stainless steel construction provides long service life even in demanding production environments with frequent cycling.
