Optical Precision Manufacturing Services for Custom Optomechanical Parts

XY-GLOBAL provides optical precision manufacturing services for custom optomechanical parts used in imaging systems, laser modules, inspection equipment, medical-related optical devices, and precision instruments.

We do not manufacture optical lenses or coatings. Our focus is the precision mechanical parts around optical elements — the parts that hold lenses, position sensors, support mirrors, protect modules, and keep the optical assembly stable.

For these parts, normal CNC machining is often not enough. Optical mechanical components usually require controlled bores, accurate threads, flat mounting faces, clean edges, stable anodizing, and reliable inspection of critical dimensions.

Optical Parts We Commonly Manufacture

Most optical parts are made according to customer drawings and 3D models. The key is not only machining the shape, but also understanding which areas affect optical alignment and assembly.

Typical materials include Aluminum 6061 / 7075, stainless steel 304 / 316L / 17-4PH, titanium, brass, copper alloy, PEEK, POM, alumina ceramic, and zirconia ceramic.

For optical housings and lens barrels, aluminum with matte black anodizing is commonly used when reflection control or surface protection is required. For parts requiring higher strength or long-term stability, stainless steel or titanium may be considered.

Reference Manufacturing Capabilities

The final tolerance depends on part size, geometry, material, and inspection method. The values below are reference ranges we often review for precision optomechanical parts.

For optical precision manufacturing, we do not recommend applying the tightest tolerance to every dimension. A better approach is to mark the true functional areas first: lens seat, sensor seat, mounting face, bore, thread, positioning hole, or reference surface.

This helps control cost while keeping the important dimensions accurate.

Application Example: Black Anodized Aluminum Lens Barrel

A typical optical project involved a small aluminum lens barrel used in an imaging device. The part included an internal bore, external fine thread, positioning shoulder, retaining groove, and several small mounting holes.

The part size was approximately OD 28 mm × length 42 mm. The key requirements were stable lens positioning, smooth thread assembly, and low-reflection internal surface after black anodizing.

After reviewing the drawing, we focused on four areas:

• Inner bore tolerance for lens fit

• Coaxiality between the bore and thread

• Shoulder height for lens positioning

• Burr control around grooves and small holes

The part was produced by CNC turning and milling, followed by matte black anodizing. Critical features were inspected before shipment, including bore size, thread fit, shoulder height, and visual condition of the anodized surface.

This type of component may look simple, but small errors in the bore, thread, or positioning shoulder can affect optical alignment. That is why we review the drawing before production and separate critical optical features from non-critical outer surfaces.

How We Support Optical Precision Projects

XY-GLOBAL supports prototype, small-batch, and repeat production for custom optical mechanical components. Our team can review 2D drawings and 3D models before production to identify machining risks, tolerance conflicts, surface treatment concerns, and inspection points.

For optical parts, we pay special attention to:

• Burrs around holes, slots, grooves, and threads

• Coaxiality and concentricity of lens-related features

• Flatness of mounting and reference surfaces

• Thread quality for smooth assembly

• Surface finish before and after anodizing

• Cosmetic consistency for visible optical housings

• Clean packaging to reduce handling marks before assembly

We can also support inspection reports for key dimensions when required. For medical-related optical projects, production and documentation can be reviewed under ISO 9001 and ISO 13485 quality system requirements.

What We Need for Quotation

To quote optical precision manufacturing services accurately, please provide:

• 2D drawing with tolerances

• 3D model, such as STEP, STP, X_T, or IGS

• Material requirement

• Quantity for prototype, pilot batch, or repeat order

• Surface treatment requirement, such as black anodizing

• Critical dimensions or assembly areas

• Inspection report requirement

• Application information, such as lens mount, sensor housing, laser module, or imaging device

If the drawing has many tight tolerances, we can help review which dimensions truly affect function and which areas can use normal machining tolerance. This can reduce unnecessary machining cost and improve production stability.

FAQ

What are optical precision manufacturing services?

Optical precision manufacturing services refer to the production of precision mechanical parts used in optical assemblies, including lens barrels, optical housings, mirror mounts, spacers, brackets, holders, and laser module components.

Do you manufacture optical lenses?

No. We mainly manufacture optomechanical components used around lenses, mirrors, sensors, and laser modules. We do not focus on optical glass grinding or optical coating.

Can you make black anodized optical parts?

Yes. We can manufacture black anodized aluminum optical parts such as lens barrels, housings, mounts, and internal structural components.

What tolerances can you support?

For many precision machined features, ±0.01 mm to ±0.02 mm is common. Critical local features such as bores, reference surfaces, and ground areas can be evaluated separately based on the drawing.

What files are needed for quotation?

A 2D drawing with tolerances is recommended, and a 3D model is helpful for complex parts. STEP, STP, X_T, IGS, and PDF files are commonly used.
