Frequently Asked Questions
What is a 5-axis CNC machined aluminum optical instrument lens barrel support?
A high-precision complex structural component designed for industrial optical instruments requiring complex curved profiles, multiple mounting holes at different angles, irregular locating slots, and deep inner bore for lens mounting. All features are produced in a single one-piece 5-axis CNC machining operation with hard anodizing treatment.
Why is 5-axis simultaneous CNC machining essential?
5-axis capability enables single-setup production of complex curved profiles, multi-angle holes, and deep features that cannot be efficiently machined with 3-axis equipment. This eliminates cumulative tolerance buildup and ensures accurate relative positioning critical for optical alignment.
What is Type III hard anodizing and why is it used?
Type III hard anodizing creates a thick aluminum oxide layer (25-75μm) providing surface hardness of 60-70 Rockwell C, excellent wear resistance, and superior corrosion resistance. The matte dark gray appearance reduces glare for industrial optical applications.
What dimensional inspection is performed?
Full dimensional inspection using ZEISS CMM verifies position tolerance of mounting holes relative to optical axis, cylindricity of inner bore, perpendicularity of mounting surfaces, and concentricity of critical features. Inspection occurs both before and after anodizing treatment.
What customization options are available?
We offer customization of curved outer profiles, mounting hole configurations, bore specifications, slot designs, material selection (6061/7075/2A12 aluminum), and surface treatment options. Our engineering team provides DFM feedback to optimize designs for manufacturing.
