Component Specifications

Definition
Alignment pins are precision-engineered cylindrical components designed to ensure exact positioning and alignment between mating parts in mechanical assemblies. In blade holder frames, they provide critical registration points that maintain dimensional accuracy, prevent misalignment during operation, and enable repeatable assembly and disassembly processes. These pins typically feature tight tolerances and specific geometric configurations to interface with corresponding bushings or holes.
Working Principle
Alignment pins work by providing precise geometric reference points between mating components. When inserted into corresponding holes or bushings, they create a fixed spatial relationship that prevents relative movement in critical directions. This ensures components maintain their intended alignment during assembly, operation, and maintenance cycles. The interference or clearance fit between pin and hole determines the precision of alignment and ease of assembly.
Materials
Typically made from hardened tool steel (AISI D2, A2, or O1), stainless steel (304 or 416), or carbide for extreme wear resistance. Surface treatments may include nitriding, chrome plating, or titanium nitride coating for enhanced durability and corrosion resistance.
