FAQ

Robotics CNC questions.

Joint bearing seats: ±0.01 mm (for direct bearing press-fit). General mounting: ±0.05 mm. Structural features: ±0.1 mm. Cosmetic: ±0.3 mm. Robotics is tolerance-intensive on bearing and motor interfaces — these are critical for smooth motion and repeatability. We CMM-inspect critical features by default.

Yes — ISO 9409-1 tool flanges are standard. Common interfaces: ISO 9409-1-40-4-M6 (small robots), 9409-1-63-5-M8, 9409-1-80-6-M10, 9409-1-125-6-M10 (large industrial). We maintain CAD templates for common ISO 9409-1 flanges; specify flange size in RFQ and we apply the correct pattern.

Yes — robotics customers are weight-sensitive. Techniques we use: 7075-T6 over 6061 (40% stronger, allows thinner walls), pocket out non-load-bearing material, avoid overspec tolerances that force thick ribs, topology-optimized design review (we suggest weight reductions). For extreme weight reduction: titanium Gr.5 over aluminum (40% lighter than steel for same strength).

Yes — humanoid robot startups are a growing customer base. Common work: leg and arm joint housings (weight-critical, precision bearing seats), actuator housing for harmonic drives, cable management hardware. We understand the balance of weight, strength, and cosmetic finish that humanoid robots require.

Typical robotics progression: 5–10 CNC prototypes (v1 testing) → 50–100 pilot production → 500+ production. We support the entire journey. For production quantities, CNC remains competitive up to 5,000–10,000 units per year on complex robotics components. Above that, investment casting or specialty processes may become more cost-effective.

Yes — our 5-axis capability (DMG Mori DMU 80 P, Hermle C 42 U, Makino V56i) is well-suited to modern robotics design. Topology-optimized brackets, integrated joint housings with complex internal features, multi-orientation mounting patterns — all routine. 5-axis typically required for unified joint housings with bearing seats on multiple axes.
