Utilizing a high-dynamic five-axis linkage machining center, coupled with specialized vibration-damping tools and processes, high-precision machining of complex streamlined thin-walled shells is achieved. Wall thickness uniformity can reach [percentage missing]. ±0.1𝗆𝗆 The deformation is controlled within 0.05mm, ensuring structural rigidity while maintaining lightweight design.

② Precision bearing bore and motor mounting surface are machined in one clamping operation

By using customized chemical fittings and a precision rotary table, the output flange bearing hole and motor installation stop can be completed in a single clamping operation.
Machining of key features such as ports and servo mounting surfaces. Ensuring coaxiality of all mounting surfaces. ≤Φ0.01mm With end face runout ≤0.005mm and flatness ≤0.008mm, it provides a perfect reference for precision transmission systems.

③ Precision machining of internal cooling channels and cable channels

Utilizing micro-volume lubrication (MQL) high-speed milling and deep hole drilling technology, complex internal cavity features such as internal spiral cooling channels, sensor cable channels, and vent valve interfaces are precisely machined. The channel surface is smooth (Ra ≤ 1.6μm), burr-free, ensuring cooling efficiency and smooth wiring.

We can provide one-stop solutions for automated testing,sorting,and precision test fixtures in conjunction with package-level system products.

①Topology optimization and structural contouring precision machining

Based on the topology optimization or finite element analysis model provided by the client, high-speed cutting technology is used to precisely realize the optimized structure of internal contour ribs, reinforcing ribs, and weight-reducing cavities, minimizing weight while meeting strength and stiffness requirements (weight control precision). ±1% ).

②Stress relief and dimensional stability processes

The aluminum alloy shell is subjected to solution aging treatment (T6), and for large or complex structures, multiple stress-relieving annealing is arranged. Symmetrical machining and layer milling are adopted to control machining stress and deformation to the maximum extent and ensure long-term dimensional stability.

③Dynamic Equilibrium and Vibration-Resistant Structure Fabrication

For high-speed rotating components, precision milling of dynamic balancing grooves is performed on key parts of the housing, and fine adjustments can be made through local additive manufacturing or the insertion of counterweights to meet the low vibration requirements under high-speed operation.

①High-precision machining of sealing grooves and O-ring grooves

Using custom-designed cutting tools, radial and end-face static sealing grooves are precision milled. Groove width, depth, and fillet tolerances are strictly controlled within ±0.02mm, resulting in a clear profile and providing a reliable sealing foundation for achieving IP65/IP67 or even higher protection ratings.

②High wear resistance and high appearance surface treatment

We offer a variety of surface treatment options: hard anodizing (thickness 25-50μm, hardness ≥HV400), micro-arc oxidation (ceramic layer), precision sandblasting (multiple mesh sizes available), high-gloss polishing, and RAL/PANTONE standard color spraying, to meet the requirements of wear resistance, corrosion resistance, and brand appearance.

③Corrosion protection and conductivity treatment

For special application environments, chemical nickel plating, conductive oxidation, and other treatments can be provided to meet corrosion resistance, electromagnetic compatibility (EMC), or grounding requirements.

①Virtual assembly and tolerance chain analysis support

It provides 3D scanning data (STL format) of the processed shell, supporting customers to perform virtual assembly and tolerance chain analysis, and providing early warning of potential interference or fit problems.

②Functional trial installation and leakage testing

Before leaving the factory, we can perform functional trial assembly of key components such as bearings and seals based on the customer's specifications. We also provide airtightness (pressure or helium test) and waterproof test reports to ensure sealing reliability.

③Full-size digital inspection and data package delivery

We use large coordinate measuring machines, laser scanners, profilometers, and other equipment to conduct a full inspection of the critical dimensions, geometric tolerances, and sealing surface quality of each housing component. The delivered product includes a complete inspection report, 3D model comparison images, and a digital data package containing material certifications.
