Machined Multi-Hole Disc Flange

Disc-shaped mechanical interfaces with a central bore and concentric arrays of mounting holes are critical for shaft alignment and component coupling in rotating assemblies. The visible stepped profile suggests a design optimized for axial positioning, where the flat face provides a stable seating surface against mating parts while the hub or recessed center accommodates shaft clearance.

Manufacturing these components requires precise CNC turning to maintain tight concentricity between the outer diameter, inner bore, and peripheral hole patterns. Uniform spacing of the drilled holes is essential to prevent vibration and ensure balanced rotation at operational speeds. Surface finish on the contact faces must be controlled to minimize friction and wear during assembly, often necessitating secondary grinding or fine milling operations depending on the specified tolerance class.

Production capabilities include high-precision vertical turning centers and machining centers capable of handling complex hole patterns and maintaining geometric tolerances across batches. Material selection ranges from carbon steels and alloy steels for high-strength applications to stainless steel or aluminum for corrosion resistance and weight reduction. Final specifications, including heat treatment requirements and surface coatings such as zinc plating or black oxide, are determined based on the specific load conditions and environmental exposure of the end-use application.
