CNC Machined Stainless Steel Lens Holder Ring for Medical Endoscope Optical Modules
This product case focuses on a stainless steel lens holder ring used inside a medical endoscope optical module. The part supports the optical stack, maintains the lens position and provides side features for assembly or locking. Although the geometry is compact, the manufacturing challenge is substantial because bore accuracy, concentricity, surface quality and burr control all influence assembly performance.

Application
The ring can be used in endoscope lens modules, camera head subassemblies, inspection optics, illumination carriers and other compact medical imaging devices. It is suitable for prototype validation, pilot production and low-volume precision batches.

Material Options
Common materials include 303, 304 and 316L stainless steel for corrosion resistance and cleaning compatibility. Aluminum can be selected for lightweight prototypes, while titanium may be considered where strength-to-weight ratio is important. Material certificates can be supplied when requested.

Key Machining Features
The part includes a precision internal bore, reference shoulder, outside locating diameter, small side holes, chamfers and optional thread features. Turning establishes the core cylindrical geometry, while milling or live-tool operations create side details. Controlled clamping and finishing cuts reduce distortion and preserve concentricity.

Quality Control
Inspection can cover bore size, OD, shoulder height, concentricity, runout, hole position, thread quality, chamfer condition and surface finish. Optical measurement, CMM, bore gauges and microscope review are selected according to drawing tolerance and batch size.
Finishing and Packaging
Parts may be passivated, cleaned, dried and packed individually in trays, foam inserts or sealed bags. Packaging is planned to avoid contact damage, mixed lots and particle contamination during international shipment.
FAQ
Can the lens holder ring be customized?
Yes. Bore size, outer diameter, side holes, threads, chamfers, material and finish can be made according to customer drawings.
What tolerance range can be discussed?
Tolerance depends on material, geometry and inspection method. Critical bores and locating diameters should be clearly marked on the drawing.
Is 316L stainless steel available?
Yes. 316L can be used when corrosion resistance and cleaning compatibility are required.
Can you support prototype quantities?
Yes. Prototype and low-volume batches are typical for optical module development and verification.
How are side-hole burrs checked?
Side holes are deburred and inspected visually or under microscope depending on the drawing and application risk.
Can parts be packed individually?
Yes. Individual bags, trays, foam inserts and lot labels can be arranged according to the purchase requirement.
