Core Service: Custom high-precision CNC machining for industrial & humanoid robot components
Robot joint bushings are critical core components for industrial and collaborative robots, directly governing positioning accuracy, motion stability and overall service life. Even tiny machining deviations cause joint backlash, vibration, noise and accelerated wear, resulting in poor robot repeatability and higher maintenance costs.
Most EU and US robot manufacturers struggle with inconsistent bushing precision and unreliable lead times for custom prototypes and mass orders. As a professional Shanghai precision machining factory, Shanghai Jinxi Precision Machinery delivers standardized robot bushing machining, data-backed quality control and transparent delivery schedules to eliminate your procurement risks.
Strict Machining Standards for Robot Joint Precision Bushings (Data-Supported)
For harmonic reducers, RV reducers and rotating robot joints, our bushings strictly follow EU industrial precision standards with verified, stable technical parameters:
Dimensional tolerance: Strictly controlled within ±0.005mm, meeting H7 precision fit standard for robot bearing holes
Geometric tolerance: Concentricity & perpendicularity ≤ 0.003mm, eliminating joint jitter and transmission deviation
Surface roughness: Ra ≤0.8μm, reducing friction coefficient and extending component fatigue life by 35%+
Applicable materials: 304/316 stainless steel, 6061/7075 aluminum alloy, brass, and wear-resistant alloy (customizable per client’s working conditions)
Standard Machining Process of Jinxi Robot Joint Bushings
Robot joint bushings are prone to stress deformation and dimensional drift. Jinxi adopts a standardized 6-step precision process tailored for robot core parts to guarantee long-term stability:
1.Material Selection & Preprocessing
We select low-thermal-expansion, high-rigidity materials and apply aging treatment to eliminate internal stress and prevent operational dimensional deviation.
2.5-Axis CNC Rough Machining
Imported 5-axis CNC centers complete one-clamp rough machining for inner holes, outer circles and positioning surfaces, avoiding repeated clamping errors.
3.Stress Relief Secondary Aging
Secondary stress relief aging eliminates cutting-induced stress, solving the common industry issue of delayed part deformation.
4.Precision Finishing & Fine Boring
Precision fine boring and finishing strictly maintain micron tolerances to meet high-precision robot assembly requirements.
5.Surface Treatment
Custom anodizing, passivation and anti-wear coatings enhance corrosion and wear resistance for high-intensity working conditions.
6.Full-Parameter Quality Inspection
Full inspection via CMM equipment covers all dimensions and geometric tolerances. We provide official test reports with full data traceability for overseas clients.
Transparent Production Capacity Guarantee
Stable lead times are critical for overseas robot projects. Jinxi offers clear, reliable delivery cycles for custom robot bushing orders:
Large-batch customized orders: Negotiable customized cycle, supporting stable long-term OEM/ODM cooperation
