Custom-made precision aluminum lens barrel parts – manufactured using reliable 5-axis CNC machining
Custom-made precision aluminum lens barrel parts - manufactured using reliable 5-axis CNC machining
Ganyuan Factory has focused on manufacturing aluminum lens barrel parts for over 20 years. Relying on high-precision CNC equipment and optical-grade surface treatment technology, we strictly control the coaxiality of the barrel, the smoothness of the inner wall, and the precision of the assembly interface to ensure that the lens barrel is both lightweight, highly rigid, and has excellent optical stability.
Core Characteristics and Advantages of CNC Machining for Aluminum Lens Barrel Parts
As a key structural component of optical systems, the performance of aluminum lens barrels directly affects imaging accuracy and system stability in fields such as aerospace, precision measurement, and high-end photography. Their machining quality must simultaneously meet stringent dimensional and positional tolerances, lightweight requirements, and thermal stability indicators. CNC machining, with its high precision and digital control capabilities, provides a systematic solution for the high-quality manufacturing of aluminum lens barrels.

Core Characteristics of CNC Machining for Aluminum Lens Barrels
Achieving Micron-Level Coaxiality and Complex Internal Cavity Forming
Aluminum lens barrels typically feature multi-segment stepped internal holes, precision sealing grooves, and weight-reduction structures. A five-axis machining center completes the machining of both inner and outer surfaces in a single setup, ensuring that the coaxiality between the lens mounting surface and the mechanical interface is ≤0.005mm and the end face perpendicularity is ≤0.003mm.
Ensuring Thermal Stability and Stress Control
Through finite element analysis and the linkage of CNC process parameters, a variable parameter machining strategy is adopted in the lens barrel flange area, improving the uniformity of residual stress distribution by 60%. A low-temperature constant-temperature cutting system ensures that the dimensional change rate of the 6061-T651 aluminum alloy lens barrel is ≤3μm/100mm under operating conditions ranging from -50℃ to +80℃.
Achieving Optical-Grade Surface Quality
Utilizing diamond tool mirror-finish cutting technology, coupled with an online waviness detection system, the roughness of the lens barrel mounting surface reaches Ra≤0.025μm, and the surface shape accuracy is ≤0.1μm. Ultrasonic-assisted polishing creates micro-chamfers on the threaded mounting surface, eliminating assembly stress concentration and reducing lens offset to within 0.002mm.
Technological Development Trends
Integration of diffractive optical elements with CNC machining: Direct machining of diffraction positioning references on the lens barrel end face; ion beam shaping technology to compensate for machining errors in large lens barrels; digital twin systems to simulate lens barrel deformation under different gravity environments, optimizing the support structure design in advance. 
CNC machining technology is driving the upgrade of aluminum lens barrels from traditional mechanical parts to optomechanical integrated core components. It not only solved the problem of high-precision thin-walled tube machining, but also provided key technological support for the independent development of my country's high-end optical equipment. With the increasing demand in fields such as space exploration and precision manufacturing, CNC-machined aluminum lens tubes will continue to make breakthroughs in ultra-lightweighting, intelligent thermal control, and rapid response, becoming an important technological foundation for China's optical industry.
