Technical Capabilities

CNC precision optics manufacturing involves high-accuracy machining processes to produce optical components and housings with exacting dimensional tolerances and superior surface finishes. These components are typically used in imaging systems, laser assemblies, aerospace sensors, and medical devices where alignment, clarity, and mechanical stability are critical.

3-axis, 4-axis, and 5-axis CNC milling, along with precision turning, enable complex geometries, tight tolerances, and fine surface finishes required in optical applications. Multi-axis capabilities allow for reduced setup次数 and improved positional accuracy, especially for non-symmetric or freeform optical mounts and enclosures.

Parameter	Description
Machining Capabilities	3-axis, 4-axis, and 5-axis CNC milling; CNC turning (including live tooling for mill-turn)
Tolerance Range	±0.0001″ (±0.0025 mm) typical; tight feature-to-feature and concentricity tolerances maintained for optical alignment
Surface Finish (Ra)	As low as 8–16 μin (0.2–0.4 μm); polished finishes available for critical sealing or light control surfaces
Positional Accuracy	< ±0.0002″ (±0.005 mm) with 5-axis continuous interpolation for complex contours
Max Work Envelope (Milling)	20″ × 40″ × 25″ (508 × 1016 × 635 mm); larger upon request with multi-setup planning
Max Turning Diameter	Up to 12″ (305 mm); bar stock capacity up to 3″ (76 mm) for Swiss-type turning
Materials Supported	Aluminum (6061, 7075), Steel (4140, 17-4 PH, 303/304 SS), ABS (for prototyping), Nylon (6/66, glass-filled options)
Material Suitability	Aluminum: lightweight, anodizable for durability; Steel: high rigidity, EMI shielding; ABS: low-cost prototypes; Nylon: wear-resistant, low friction for moving optical stages
Secondary Operations	Deburring, precision cleaning, metrology (CMM, optical comparators), anodizing, plating, black oxide, passivation
Quality Standards	ISO 9001:2015, AS9100D (aerospace), full first-article inspection (FAI) and PPAP documentation available

Components such as lens barrels, mirror mounts, optomechanical stages, and sensor housings benefit from multi-axis machining, which ensures alignment of optical bores and mounting surfaces within microns. Material selection is driven by thermal stability, weight, corrosion resistance, and compatibility with optical coatings or adhesives. Nylon and ABS are typically used in non-critical or prototype assemblies where cost and speed are prioritized, while aluminum and steel dominate in production-grade precision optics systems.

From CAD to Part: The Process

Honyo Prototype CNC Precision Optics Workflow

Our CNC precision optics process integrates advanced manufacturing with rigorous technical validation to deliver components meeting stringent optical performance requirements. The workflow begins when a client uploads a native CAD file (STEP, IGES, or native SOLIDWORKS) through our secure customer portal. This file must include critical optical specifications: surface form tolerances (e.g., λ/4 @ 632.8nm), surface roughness (e.g., <5Å RMS), material type (e.g., N-BK7, Fused Silica, ZnSe), and coating requirements. Incomplete specifications trigger an automated notification for clarification before proceeding.

AI-Powered Technical Quoting
The uploaded CAD undergoes immediate analysis via our proprietary AI engine, which cross-references geometric complexity, material properties, and tolerance demands against historical production data. Unlike generic quoting systems, our AI evaluates optical-specific constraints:
Feasibility of achieving required surface figure and finish via CNC diamond turning or milling
Material stress risks during machining (e.g., crystalline structure challenges in CaF₂)
Metrology validation pathways for specified tolerances
The output is a formal technical quotation within 4 business hours, detailing not only cost and lead time but also preliminary process recommendations and potential DFM flags. This phase includes a preliminary risk assessment score (1-5 scale) for critical features.

Optical-Specific DFM Analysis
All quotes undergo mandatory Design for Manufacturability (DFM) review by our optical engineering team. This is not a checklist but a collaborative technical dialogue focused exclusively on optical performance preservation. Key considerations include:

Feature Category	Standard CNC DFM Focus	Honyo Optical DFM Focus
Geometry	Draft angles, wall thickness	Edge thickness for mounting stress, clearance for metrology probes
Tolerances	±0.05mm dimensional	Surface power (fringes), irregularity (λ/20), centering (arcsec)
Material	Machinability, cost	Homogeneity requirements, birefringence sensitivity, coating adhesion
Metrology	Caliper/ CMM accessibility	Interferometer path clearance, reference surface definition

The DFM report identifies actionable optimizations: adjusting edge profiles to prevent chipping, modifying datums for alignment during coating, or recommending stress-relief steps for brittle materials. Clients receive annotated CAD markups and a revised technical proposal within 72 hours of DFM initiation.

Precision Production Execution
Approved designs enter production in our ISO Class 7 cleanroom environment using dedicated optical CNC platforms (e.g., Moore Nanotech 350FG, Precitech Optimum 2800). The process sequence is strictly controlled:
Rough Machining: High-speed milling with diamond-coated tools to achieve near-net shape while minimizing subsurface damage
Fine Machining: Sub-aperture deterministic finishing (e.g., MRF, IBF) for λ/10 surface accuracy and <2Å roughness
In-Process Metrology: Real-time verification via Zygo interferometers and white-light profilometers after each critical stage
Stress Relief: Annealing cycles for crystalline materials per MIL-O-13830A standards
All environmental parameters (temperature ±0.5°C, humidity 45±5% RH) are logged to correlate with metrology results. Production batches include witness samples for coating validation.

Verified Delivery Protocol
Final inspection generates a comprehensive test report per ISO 10110, including:
Full-aperture interferometry maps (power, irregularity, RMS)
Scatterometry data for surface roughness
Dimensional verification of mechanical interfaces
Coating performance metrics (if applicable)
Components are packaged in class 100 VCI bags with desiccant, mounted in custom foam cradles, and shipped in shock-monitoring containers. Delivery includes full traceability: material certificates, process logs, and metrology datasets. Typical lead time from DFM sign-off to shipment is 15-25 business days for prototypes, with expedited optical polishing options available.

This end-to-end process ensures optical components meet functional performance targets while minimizing program risk through embedded technical validation at every phase. We maintain AS9100 and ITAR compliance for defense and aerospace applications.
