CNC Aluminum 6061 Optical Instrument Mounting Base Natural Finish

Product Specification

Dongguan Changxinda Precision Technology Co., Ltd. specializes in CNC precision machining of aluminum 6061 optical instrument mounting bases with natural finish. Manufactured using advanced 4-axis and 5-axis CNC milling centers, these precision mounting bases deliver the dimensional accuracy and surface quality demanded by modern optical systems and measurement instruments. The natural aluminum finish with visible machining marks and silvery metallic luster showcases the authentic CNC machining quality that customers trust for critical optical applications.

The aluminum 6061 alloy offers excellent machinability, good corrosion resistance, and superior dimensional stability. With medium strength, good weldability, and excellent surface finish characteristics, aluminum 6061 is the preferred choice for precision optical mounting applications. The natural finish preserves the authentic appearance of machined aluminum, displaying the characteristic tool marks and bright metallic sheen that indicate high-quality CNC processing. This finish is ideal for applications where the natural aluminum appearance is preferred or where additional surface treatments are not required.

Precision is fundamental to optical mounting base performance. Changxinda's CNC milling operations achieve tolerances of +/-0.01 mm on critical dimensions, ensuring consistent alignment across production batches. End face flatness is controlled to extremely strict standards, typically achieving flatness within 0.01-0.02 mm across the mounting surface. This level of flatness is critical for optical systems where any deviation can cause alignment errors, measurement inaccuracies, or degraded optical performance. The rectangular center opening and surrounding threaded holes, counterbored holes are precision machined to exact specifications.

The mounting base features a rectangular center opening milled to precise dimensions, surrounded by multiple threaded holes and counterbored holes for secure attachment to optical assemblies. These mounting features are machined using high-precision drilling and tapping operations, ensuring that the base aligns correctly with corresponding optical components. The natural aluminum finish provides a clean, professional appearance while maintaining the dimensional stability and flatness required for precision optical applications. The visible tool marks from CNC machining demonstrate the authentic manufacturing process.

Production flexibility is a key advantage. Changxinda supports the full production lifecycle from prototype development to mass production. Quick-turn prototyping enables rapid design validation and optical testing, while scalable production capacity accommodates batch orders ranging from small series to large quantities. Each optical mounting base undergoes rigorous in-process inspection and final quality verification using coordinate measuring machines, surface flatness measurement equipment, and precision gauges, with statistical process control applied to critical dimensions.

Dongguan Changxinda Precision Technology Co., Ltd. is ISO 9001:2015 certified and committed to delivering precision machined components that meet the highest industry standards. With a team of more than 30 experienced professionals and comprehensive 4-axis/5-axis CNC machining capabilities, the company provides fast delivery, responsive communication, and reliable quality that has resulted in many successful cooperation cases with satisfied customers worldwide.
