Optical Lens Housings CNC Machining for Semiconductor Industry

Simple lens cell housings with standard geometry typically require 1-2 weeks from approved drawings to delivery. Complex multi-bore assemblies with tight concentricity requirements need 2-3 weeks including precision boring, honing, and inspection. Components requiring surface treatments add 3-5 business days for anodizing and coating processes. Prototype quantities for optical system development can be expedited to 5-7 business days for most configurations. We provide detailed scheduling information during quotation and coordinate surface treatment timing to meet your project deadlines.
 

Type II black anodizing typically adds 0.0002-0.0005″ per surface, which we account for in machining dimensions. Critical bore diameters are often masked during anodizing or are post-machined to final dimensions after coating. We provide detailed dimensional callouts specifying “before coating” or “after coating” requirements. Our anodizing partners maintain tight process controls for consistent coating thickness. For maximum precision, critical optical interfaces can be machined after coating application. We coordinate all surface treatment specifications to ensure final dimensions meet your optical system requirements.
 

We routinely achieve bore tolerances of ±0.0002″ through precision boring and reaming operations. For critical applications, honing processes can achieve ±0.0001″ with surface finishes of Ra 4-8 microinches. Concentricity between multiple bores within 0.0005″ TIR is standard through single-setup machining strategies. Perpendicularity of mounting surfaces to bore axis within 0.0002″ ensures proper lens seating without tilt. CMM inspection and air gauge measurement verify all critical dimensions before and after surface treatment.
 

Aluminum 6061-T6 is most popular due to excellent machinability, good thermal stability, light weight, and compatibility with Type II black anodizing for stray light control. Titanium Grade 5 (Ti-6Al-4V) provides superior dimensional stability with low thermal expansion, ideal for precision optical systems. Stainless steel 303/304 offers rigidity and corrosion resistance. Brass C360 provides excellent machinability for prototype development. Material selection depends on environmental conditions, weight requirements, thermal considerations, and required surface treatments.
