Manufacturing Insight: Micro Machining Services

Precision Micro Machining Solutions for Demanding Engineering Applications

Honyo Prototype delivers advanced CNC micro machining services engineered to meet the exacting requirements of medical devices, aerospace components, semiconductor tooling, and other high-precision industries. Our specialized capabilities in CNC Swiss turning and multi-axis milling consistently achieve tolerances down to ±0.0002 inches (±0.005 mm) on complex geometries with feature sizes below 0.5mm. We machine challenging materials including titanium, nitinol, stainless steel, and engineered polymers with uncompromised surface integrity and repeatability.

Unlike conventional machining providers, Honyo integrates proprietary fixturing, sub-micron toolpath optimization, and real-time process monitoring to eliminate common micro-machining pitfalls such as tool deflection, burr formation, and thermal distortion. Every component undergoes rigorous first-article inspection using coordinate measuring machines (CMM) and optical comparators to validate dimensional accuracy against your critical-to-quality specifications.

Technical Capabilities

Honyo Prototype delivers precision micro machining services tailored for complex, high-accuracy components across aerospace, medical, and industrial sectors. Our capabilities include advanced 3, 4, and 5-axis CNC milling and precision turning, optimized for tight tolerance requirements down to ±0.0002″ (5 µm). These multi-axis systems enable intricate geometries, reduced setup cycles, and superior surface finishes on a range of engineering-grade materials.

We specialize in machining both metallic and engineering thermoplastic materials, including Aluminum (6061, 7075), Steel (4140, 17-4 PH, 303, 316), ABS, and Nylon (6/66/46), ensuring material compatibility with functional and environmental demands. All processes are supported by in-house metrology, including CMM and optical inspection, to validate dimensional accuracy and repeatability.

From CAD to Part: The Process

Honyo Prototype delivers precision micro machining services through a rigorously controlled five-stage workflow designed for speed, accuracy, and zero-defect outcomes. Our process begins when customers upload native CAD files (STEP, IGES, Parasolid) or 3D models via our secure client portal. This triggers immediate geometric analysis by our proprietary AI quoting engine, which evaluates feature complexity, material utilization, and machine time requirements against live production capacity data. Unlike manual quoting systems, our AI generates binding cost estimates with tolerance validation within 2 hours for 95% of submissions, eliminating traditional 3-5 day quotation delays.

The AI Quote stage transitions directly into mandatory Design for Manufacturability (DFM) review. Our engineering team conducts a full technical assessment focusing on micro-scale constraints including minimum wall thicknesses (<0.1mm), aspect ratios exceeding 20:1, and surface finish requirements down to Ra 0.05µm. Critical DFM parameters are documented through structured analysis:

DFM Parameter	Micro Machining Threshold	Honyo Standard Action
Feature Size Tolerance	±0.001mm to ±0.005mm	Electrode design validation
Corner Radius	<0.05mm internal	Tool path simulation verification
Material Hardness	>55 HRC	EDM process substitution
Surface Roughness	Ra < 0.1µm	Multi-stage polishing protocol

Approved designs enter micro-machining production on dedicated DMG MORI ultra-precision centers with thermal compensation systems and sub-micron positioning accuracy. All operations occur in ISO Class 7 cleanrooms with environmental controls maintaining ±0.5°C temperature stability. We utilize custom-tuned toolpaths for micro-milling, wire EDM, and micro-turning processes, with real-time in-process metrology via Zeiss O-INSPECT multisensor systems. Every component undergoes 100% first-article inspection against GD&T callouts before batch processing, with full traceability of cutting parameters and inspection data.

Final delivery includes certified components in ESD-safe packaging with comprehensive documentation: CMM reports showing actual vs. nominal dimensions at critical features, material certification, and process validation records. For medical and aerospace clients, we provide full AS9102 or FDA-compliant FAI packages. Standard lead time from CAD upload to shipment is 72 hours for prototypes and 5-7 days for low-volume production, with expedited 24-hour micro machining available for qualifying geometries. All shipments include digital twins of measured data for seamless integration into customer quality management systems, ensuring supply chain continuity from prototype to production.
