Technical Capabilities
Micro CNC machines are compact, high-precision computer numerical control systems designed for machining small-scale components with exceptional accuracy. These machines support multi-axis operations—commonly 3, 4, or 5-axis milling—and often integrate micro-turning capabilities for complex geometries. They are engineered for tight tolerance applications, typically holding dimensional accuracy within ±0.001 mm (±0.00004 in) or better, depending on setup and material.
These machines are frequently used in industries such as medical device manufacturing, aerospace prototyping, electronics, and precision optics. They are capable of processing a variety of materials including metals like aluminum and steel, as well as engineering thermoplastics such as ABS and nylon. Material selection influences spindle speed, feed rates, and tooling requirements due to differences in hardness, thermal conductivity, and chip formation.
The following table summarizes key technical specifications for typical high-performance micro CNC machines used in precision manufacturing environments:
| Specification | Detail |
|---|---|
| Axes Configuration | 3-axis, 4-axis (3-axis + rotary), 5-axis (full simultaneous motion) |
| Positioning Accuracy | ±0.001 mm (±0.00004 in) |
| Repeatability | ±0.0005 mm (±0.00002 in) |
| Spindle Speed Range | 20,000 – 100,000 RPM (air or liquid-cooled high-frequency spindles) |
| Tool Diameter Range | 0.1 mm – 6.0 mm (micro end mills down to 100 µm common) |
| Work Envelope (Typical) | 100 x 100 x 75 mm (4″ x 4″ x 3″) – varies by model |
| Control System | High-resolution CNC with sub-micron interpolation |
| Linear Axis Resolution | 0.001 µm (1 nanometer in advanced systems) |
| Maximum Feed Rate | 30,000 mm/min (1,180 in/min) with high acceleration |
| Coolant/Lubrication | Mist cooling, minimum quantity lubrication (MQL), or air blast |
| Material Compatibility | Aluminum (6061, 7075), Steel (1018, 4140, stainless), ABS, Nylon (PA6, PA12), PEEK, PTFE |
| Typical Surface Finish (Ra) | 0.4 – 1.6 µm (achievable with fine toolpaths and proper parameters) |
| Feature Size Capability | Down to 10 µm (with specialized tooling and environmental control) |
| Thermal Compensation | Active thermal stabilization systems standard on high-end models |
| Vibration Damping | Granite or polymer concrete base with active/passive damping |
These machines require stable environmental conditions (temperature-controlled, low vibration) to maintain micron-level tolerances. Tool wear monitoring, in-process probing, and adaptive control systems are often integrated to ensure consistency when machining both conductive metals and abrasive or gummy polymers like nylon and ABS.
From CAD to Part: The Process
Honyo Prototype’s micro CNC machining process is engineered for precision, speed, and technical rigor, specifically addressing the unique challenges of sub-millimeter features and tight tolerances inherent in micro-manufacturing. Our integrated workflow ensures manufacturability from the earliest design stages while maintaining rapid turnaround.
The process begins with CAD File Upload through our secure customer portal. We accept native formats including STEP AP203/214, Parasolid, and IGES, with strict validation for geometric integrity. Files undergo automated topology checks to flag non-manufacturable features exceeding micro-machining physical limits (e.g., aspect ratios >15:1 for micro-mills). Unsupported formats trigger immediate client notification with conversion guidelines.
AI-Powered Quoting follows within minutes of upload. Our proprietary algorithm analyzes 127+ geometric and material parameters, including feature density, minimum wall thickness, and surface roughness requirements. Unlike manual quoting, the system cross-references real-time machine availability, tooling constraints for micro-tools (down to Ø0.02mm), and material waste factors. Quotes include granular cost drivers such as micro-tool wear compensation cycles and metrology time per feature, with typical accuracy within ±3.5% against final invoice.
DFM Analysis is the critical phase distinguishing micro from conventional CNC. Our engineers conduct a two-tier review: First, an automated check against 89 proprietary micro-machining rules (e.g., minimum chip load thresholds for micro-endmills, vibration sensitivity for thin walls). Second, a manual review by our micro-specialist team focusing on micro-scale physics—evaluating thermal deformation risks during machining, fixturing feasibility for sub-gram parts, and burr propagation paths. Key DFM outcomes include:
| Parameter | Traditional CNC DFM | Honyo Micro CNC DFM Focus |
|---|---|---|
| Minimum Feature Size | ≥0.5mm | Validated down to 0.05mm |
| Tolerance Assessment | ±0.025mm standard | Statistical process capability (CpK≥1.67) at ±0.005mm |
| Tool Access Analysis | Visual clearance | Dynamic simulation of tool deflection at 50,000+ RPM |
| Surface Finish Guidance | Ra 0.8μm typical | Vibration-damped strategies for Ra ≤0.2μm |
DFM reports provide actionable redesign recommendations with GD&T callout optimization, often reducing lead time by 30-50% through manufacturability improvements. Clients receive annotated 3D models highlighting critical zones requiring attention.
Production Execution occurs in our ISO Class 7 cleanroom environment using dedicated micro-CNC platforms (Mikron HSM 200 UCP, DMG MORI Ultra 110). Processes include:
Toolpath verification via virtual machine simulation checking for micro-scale collisions
In-process metrology using non-contact laser probes (accuracy ±0.5μm) after critical operations
Environmental controls maintaining ±0.5°C temperature stability to prevent thermal drift
Real-time force monitoring to detect tool wear before surface finish degradation
All micro-features undergo 100% post-process inspection using confocal microscopy and X-ray computed tomography for internal geometries, with full traceability to machine parameters and tool life logs.
Delivery includes comprehensive documentation: First Article Inspection reports per AS9102, material certs with microstructure analysis, and a digital twin of the as-machined part with deviation heatmaps. Small-part logistics use anti-static, vibration-damped packaging with humidity indicators, with typical delivery within 72 hours of production completion for qualified parts. This closed-loop system ensures micro-features meet stringent requirements for medical implants, semiconductor tooling, and optical components while providing engineering data to refine future designs.
