Technical Capabilities

Technical Specifications for CNC Machining Services at Honyo Prototype

As a Senior Manufacturing Engineer at Honyo Prototype, I oversee all precision machining operations. Our “CNC Hire” service provides contract machining for prototyping and low-to-mid-volume production, with a focus on 3/4/5-axis milling, turning, and tight-tolerance capabilities. Below are detailed technical specifications for our standard capabilities. All work adheres to ISO 9001 quality standards, with in-process inspection and final CMM verification.

1. Machine Capabilities

3-Axis Milling

• Travel Range: Up to 1,000 × 600 × 500 mm (X/Y/Z)
• Spindle Speed: 10,000–24,000 RPM (variable, tool-dependent)
• Tooling: ATC (Automatic Tool Changer) with 20–30 tool positions; ER32 collets for precision holding
• Typical Tolerance: ±0.005″ (±0.127 mm) standard; ±0.001″ (±0.025 mm) achievable for critical features with process optimization.
• Best For: Flat geometries, simple contours, and large parts where 5-axis isn’t required.

4-Axis Milling

• Additional Axis: Rotary B-axis (0°–360° continuous rotation)
• Travel Range: Up to 800 × 500 × 400 mm (X/Y/Z) + 360° B-axis
• Spindle Speed: 10,000–18,000 RPM (optimized for rotational stability)
• Typical Tolerance: ±0.003″ (±0.076 mm) standard; ±0.0015″ (±0.038 mm) for indexed features.
• Best For: Cylindrical features, multi-sided parts, and complex angles (e.g., turbine blades, medical implants).

5-Axis Milling

• Axes: Simultaneous 5-axis (X/Y/Z + A/B or C) with tilt-head or table-rotary configurations
• Travel Range: Up to 600 × 400 × 300 mm (X/Y/Z) + 120° A-axis / 360° C-axis
• Spindle Speed: 15,000–20,000 RPM (high-speed for fine finishes)
• Typical Tolerance: ±0.002″ (±0.051 mm) standard; ±0.0005″ (±0.013 mm) for aerospace/medical components with temperature-controlled environments.
• Best For: Freeform surfaces, complex aerospace components, and single-setup parts requiring no re-fixturing (e.g., impellers, molds).

Turning (CNC Lathe)

• Max Diameter: 200 mm (with live tooling)
• Max Length: 500 mm (bar-fed or chucking)
• Spindle Speed: 100–8,000 RPM (variable for low-speed turning of hardened steel)
• Live Tooling: Y-axis capability for milling/drilling on rotating parts
• Typical Tolerance: ±0.001″ (±0.025 mm) for diameters; ±0.0005″ (±0.013 mm) for precision shafts (e.g., hydraulic components).
• Best For: Rotational symmetry parts (shafts, bushings), threaded components, and combined turning/milling operations.

2. Tight Tolerance Standards

• Definition: “Tight tolerance” at Honyo means tolerances ≤ ±0.001″ (±0.025 mm) for metal parts and ≤ ±0.002″ (±0.051 mm) for thermoplastics. Achievability depends on:
• Part Size: Smaller features (e.g., <10 mm) require tighter process control.
• Material Properties: Thermal expansion, stress relief, and moisture sensitivity affect consistency.
• Process Controls:
  • Temperature-stabilized workshop (22°C ±1°C) for precision work.
  • In-process probing and zero-point fixturing to eliminate setup errors.
  • Statistical process control (SPC) for high-volume runs.
• Real-World Examples:
• Aluminum aerospace bracket: ±0.0005″ positional tolerance on mounting holes.
• Stainless steel medical pin: ±0.0003″ diameter tolerance for press-fit applications.
• ABS prototype housing: ±0.0015″ tolerance on snap-fit features (accounting for thermal drift).

3. Material-Specific Machining Capabilities

We specialize in precision machining across metals and thermoplastics. Key specs for your requested materials:

| Material | Common Grades | Machining Notes | Typical Tight Tolerance | Surface Finish (Ra) | Special Considerations |
|—————|————————|———————————————————————————|————————–|———————|————————|
| Aluminum | 6061-T6, 7075-T6, 2024-T3 | Excellent machinability; high chip evacuation required. Use sharp carbide tools @ 20k+ RPM. | ±0.0005″ (±0.013 mm) | 16–32 μin (0.4–0.8 μm) | Stress-relieve before finish machining; avoid coolant-induced warpage. |
| Steel | 303/304 SS, 17-4PH, 1045 Carbon | Hardened grades (e.g., 40+ HRC) require slow speeds + coolant. 17-4PH often heat-treated post-machining. | ±0.0003″ (±0.008 mm) | 8–16 μin (0.2–0.4 μm) | Use diamond-coated tools for hardened steel; control thermal distortion during heat treatment. |
| ABS | Standard, Flame-Retardant | Low thermal conductivity; prone to melting. Use high RPM (8k–15k), sharp tools, and air blast cooling only (no liquid coolant). | ±0.002″ (±0.051 mm) | 32–64 μin (0.8–1.6 μm) | Must be dried (80°C for 4+ hours) before machining to prevent moisture-related warpage. |
| Nylon | 6/6, 6/12, Glass-Filled | Highly hygroscopic; moisture causes dimensional instability. Machining requires low speeds (2k–6k RPM) and minimal tool pressure. | ±0.0025″ (±0.064 mm) | 32–64 μin (0.8–1.6 μm) | Critical: Dried at 180°F/82°C for 12+ hours. Avoid sharp corners to prevent stress cracking. |

4. Quality Assurance & Process Controls

• Inspection: CMM (Coordinate Measuring Machine) with 0.0001″ (0.0025 mm) resolution; optical comparators for small features; surface profilometers.
• Documentation: Full GD&T (Geometric Dimensioning & Tolerancing) analysis per ASME Y14.5; material certs (e.g., mill certs for metals, SGS reports for plastics).
• Prototyping Focus: We optimize for rapid iteration—typically 24–72 hour turnaround for simple parts, with DFM (Design for Manufacturability) feedback included at no cost.
• Limitations:
• For plastics, tolerances loosen for parts >100 mm due to thermal expansion.
• 5-axis work requires 3D CAD models (STEP/IGES) and feature-specific tolerance callouts.

Why Choose Honyo Prototype?

“Our integrated approach—combining precision machinery, material-specific process protocols, and rigorous QA—ensures your tight-tolerance requirements are met without compromising lead times. For example, a recent aerospace project required ±0.0005″ tolerance on a 7075-T6 aluminum bracket; we achieved it via in-process thermal compensation and SPC-controlled machining. We’re experts in turning complex challenges into repeatable, high-quality results.”
