What Robotics Parts Demand from a Precision Machining Partner
⚙
H6/H7
Bearing Bore Tolerance
Joint bearing and harmonic drive interface bores held to H6 or H7 fit. Roundness ≤0.003 mm to prevent bearing pre-load asymmetry.
○
±0.003mm
Coaxiality / Runout
Input-to-output bore coaxiality on joint housings. Critical for harmonic drive pre-load and transmission accuracy.
📐
±0.003mm
Base Plate Flatness
Reference positioning bases CMM-verified. Stress-relieved T651 eliminates long-term dimensional creep.
🔬
0.8mm
Min Wall Thickness
Fingertip shells machined to 0.8 mm wall in titanium. 5-axis simultaneous required for internal pocket access.
⚙
5-Axis Joint Housing Machining — One Setup
Multi-face joint housings require all bore positions and flange faces referenced from a single datum. 5-axis in one setup eliminates re-fixture error and maintains coaxiality ≤0.005 mm — which multi-setup methods cannot reliably deliver.
🔬
Miniature Feature Machining — Down to Ø1.5 mm
Dexterous hand phalanges with Ø1.5 mm pivot bores and 0.8 mm wall thickness demand 40,000 RPM spindles, micro-carbide tooling, and vibration-free fixturing. We maintain these as standard for robotics customers.
📐
Harmonic Drive Interface Tolerance — H6 & Runout
Harmonic drive interfaces require H6 bore and face runout ≤0.003 mm. We work with supplier tolerance documents for Harmonic Drive AG, SPINEA, and Nabtesco reducers to machine mating components to spec.
📋
CMM Full GD&T Report — Bore Position & Coaxiality
Robot joint housings inspected with full GD&T CMM report — bore diameter, roundness, cylindricity, coaxiality, perpendicularity, and fastener position. A complete functional qualification of the joint housing geometry.

Our Advantage
Why Robotics Engineers Specify Our Parts
5X
5-Axis — All Bores from One Datum
Joint housing coaxiality ≤0.005 mm between bores — only achievable in a single 5-axis setup. Re-fixturing introduces ±0.01–0.05 mm error that cannot be recovered.
H6
Harmonic Drive Interface Expertise
H6 bore, face runout ≤0.003 mm, and axial preload surfaces machined to reducer supplier spec — not generic ISO tolerances that may not satisfy the reducer’s requirements.
1.5
Miniature Machining for Dexterous Hands
Ø1.5 mm pivot bores, 0.8 mm wall, tendon channels in titanium — quoted as standard and delivered with CMM pivot-to-pivot axis alignment reports.
GD&T
Full Geometric Qualification Report
Every robot joint housing: bore diameter, roundness, cylindricity, coaxiality, flange runout, fastener position — a complete functional qualification, not a dimensional check.
