Technical Capabilities

Important Clarification Before Specs:
There is a critical industry misconception here. “Mini CNC routers” do NOT support milling, turning, or 5-axis operations for metals like aluminum or steel. This is a common confusion between routers, mills, and lathes. Let me explain why:

• Routers vs. Mills:
• Routers are designed for soft materials only (wood, plastic, foam, PCB) with low rigidity, low spindle power (<1 HP), and no coolant systems. They cannot machine metals (aluminum/steel) safely or accurately.
• Mills (CNC milling machines) are built for metalworking with high rigidity, high power (2–5+ HP), coolant systems, and precision spindles.

• Turning requires a lathe, not a router/mill. Lathes rotate the workpiece against a stationary tool—routers never do this.

• 5-Axis Limitations:
  True 5-axis machining requires a massive, rigid frame (typically industrial-grade), complex kinematics, and high torque. No “mini” machine (under $10k) can achieve true 5-axis metal machining. Even 3-axis mini mills struggle with metals beyond soft aluminum.

• Tolerance Reality:
  Tight tolerances (e.g., ±0.001″ / 0.025mm) require industrial-grade machines. Mini routers/mills typically achieve ±0.005″ (0.127mm) only in plastics—never in steel or hardened aluminum.

✅ What a Realistic “Mini CNC Mill” (Not Router) Can Do for Your Needs

If you need to machine aluminum, ABS, or nylon with tight tolerances, you need a small 3-axis CNC mill (not a router). Below are accurate specs for a professional-grade mini mill (e.g., Haas Mini Mill, Sherline, or similar industrial-grade desktop mill).

| Category | Specs for Mini CNC Mill (Not Router) | Why It Matters |
|———————|———————————————————————————————————-|———————————————————————————–|
| Axes | 3-Axis only (X, Y, Z). No true 5-axis capability. Optional 4th axis (rotary table) for indexing—not continuous 5-axis motion. | True 5-axis requires industrial machines ($20k+). Mini mills lack the rigidity for simultaneous 5-axis cuts. |
| Spindle Power | 1.5–3 HP (for aluminum/ABS). Critical for metal work.
• Not suitable for steel (requires 5+ HP + coolant). | Routers typically have <1 HP—insufficient for metals. Steel machining needs hardened tooling and coolant. |
| Table Size | 12″ x 18″ (300mm x 450mm) | Larger beds for complex parts; mini routers often have <10″ x 10″ beds. |
| Travel Range | X: 16″, Y: 12″, Z: 6″ (400mm x 300mm x 150mm) | Adequate for small parts; routers often have <10″ travel. |
| Tolerance | ±0.001″ (0.025mm) achievable in aluminum/ABS with proper setup (calibration, tooling, fixturing).
• Not possible in steel (requires industrial mill). | Mini routers typically achieve ±0.010″ (0.25mm) in plastics—unusable for precision metal work. |
| Materials | Aluminum (6061, 7075): ✅
ABS/Nylon: ✅
Steel (Mild/Tool): ❌ Requires industrial mill + coolant. | Routers melt steel; mini mills can cut soft aluminum but not hardened steel. |
| Spindle Speed | 0–24,000 RPM (variable speed) | Essential for different materials: low RPM for steel (if possible), high RPM for plastics. |
| Coolant System | Yes (flood coolant for aluminum). No coolant on routers—causes tool failure on metals. | Critical for heat control in metal machining; routers lack this entirely. |
| Frame Rigidity | Cast iron base, granite ways, high-preload ball screws | Routers use aluminum frames—flex too much for metal tolerances. |
| Controller | Industrial-grade (e.g., Siemens, Fanuc) with closed-loop servo motors | Routers use cheap stepper motors—prone to missed steps during heavy cuts. |
| Typical Use Case| Prototyping small aluminum parts, medical devices, aerospace fixtures, or high-precision plastic models. | Not for wood, signage, or hobbyist projects—those belong to routers. |

❌ Why “Mini CNC Router” Specs Are Misleading for Your Request

• Turning? Impossible. Routers/mills don’t rotate the workpiece—only lathes do.
• 5-Axis? No mini machine (under $15k) has true 5-axis capability. “5-axis” claims on cheap routers are usually marketing hype (e.g., a 4th-axis rotary table + 3-axis motion = 4-axis, not 5-axis).
• Steel Machining? Routers cannot cut steel—they lack rigidity, power, and coolant. Even mini mills struggle with steel beyond soft alloys (e.g., 1018 mild steel) and require specialized tooling.
• Tight Tolerance? Mini routers (e.g., $300–$2k desktop units) typically hold ±0.010″ (0.25mm) in plastics—far too loose for precision metal parts. Industrial mini mills achieve ±0.001″ but cost $10k+.

💡 What You Actually Need

1. For Aluminum/ABS/Nylon Prototyping:
2. Buy a small 3-axis CNC mill (e.g., Sherline 5400, Tormach PCNC 1100).
3. Expect to pay $8,000–$20,000 for a reliable machine.

4. Avoid “mini router” listings—they’re sold for wood/foam only.

5. For Steel Machining:

6. You need a desktop CNC lathe (for turning) or a full-size industrial mill (e.g., Haas VF-2).

7. Mini lathes start at $5k+; industrial mills start at $30k+.

8. For Hobbyist Wood/Plastic Projects:

9. A mini router (e.g., Shapeoko 4, X-Carve) is fine—but only for wood, acrylic, or foam.
10. Expect tolerances of ±0.010″ and no metal capability.

🔍 Key Takeaway: If you need to machine aluminum or steel with tight tolerances, ignore all “mini CNC router” listings. They are fundamentally incapable of this work. Invest in a proper industrial mini mill or lathe. For professional metal parts, contact a machine shop—they’ll have the right equipment.

From CAD to Part: The Process

Honyo Prototype – “mini-CNC router” workflow
(≤ 600 × 400 mm work envelope, 0.05 mm tolerance, 1-100 pc runs)

1. Upload CAD
   • Portal accepts STEP, IGES, STL, 3MF, SolidWorks, Fusion.
   • Auto-check: closed solid, min. feature 0.3 mm, min. wall 0.5 mm.
   • Instant file-repair bot heals 92 % of bad edges; remainder flagged in <15 s.

2. AI Quote (30–120 s)
   • Geometry classifier decides 2.5-D, 3-D or litho approach.
   • Runtime estimator converts mesh to toolpaths with 0.2–0.01 mm adaptive step-over; adds 15 % safety margin.
   • Material picker cross-checks stock shelf (aluminium 6061, 5052, brass C360, acetal, FR-4, etc.).
   • Dynamic pricing = raw blank + machine hours + consumables + finish; learning model retrained nightly on shop-floor data → ±5 % accuracy vs. final invoice.

3. DFM (Engineering sign-off, 2–4 h)
   a. Accessibility scan – 3+2 axis reachability map; flags under-cuts >0.4 mm.
   b. Thin-wall FEA – predicts chatter risk if L/t > 15; suggests tabs or thicker ribs.
   c. Burr forecast – predicts feather burrs on 304 SS if exit angle < 30°; adds chamfer tool.
