ZJK Industrial Boosts Production Efficiency for AI Servers and Robotics components with Patented Six-Flap Eccentric Chuck

ZJK announced the integration of a six-flap eccentric chuck into its production line for machining irregularly shaped, eccentric, and thin-walled workpieces. This advanced chuck significantly improves production efficiency, reduces the risk of workpiece deformation, and minimizes reliance on operator alignment skills.

 The core advantage of this six-flap eccentric chuck lies in its ability to efficiently, precisely, and conveniently clamp challenging workpieces that are difficult to secure using traditional clamping methods.

Patented by the China National Intellectual Property Administration with a 10-year term, the chuck features a unique eccentric structure that automatically adapts to the geometric center of a workpiece. It is especially effective when the geometric center (or center of gravity) does not coincide with the rotational center, or when handling workpieces with non-standard contours, such as non-circular, polygonal, or bossed/recessed surfaces. This structural innovation significantly reduces or even, in certain applications, eliminates the need for manual alignment, greatly improving clamping efficiency and consistency. It is particularly well-suited for batch processing of workpieces that share the same design but may exhibit minor variations from casting or forging.

Furthermore, the chuck distributes clamping force evenly across the contact area, especially when the jaws are custom-fitted to the shape of the workpiece. This reduces the risk of deformation, making it ideal for securing thin-walled, easily deformable parts—such as rings or sleeves—without causing flattening or distortion. Its high structural rigidity also enables it to withstand high cutting forces after clamping.

The new chuck can be easily integrated into automated or semi-automated production lines, allowing for fast and reliable clamping and unclamping through a single, simple operation. This reduces the technical requirements for operators and supports ZJK’s ongoing automation efforts.

Overall, the six-flap eccentric chuck offers excellent flexibility and cost-effectiveness, helping ZJK reduce clamping times and improve processing capabilities for complex components.

Irregular or bespoke workpieces—such as custom chassis, accelerator sleds, brazed micro-channel blocks, custom brackets, seals, and EMI shields—are becoming increasingly critical in AI servers, robotics and industrial automation. Parallel to the rapid expansion of global AI server market, particularly accelerator-server segment, the demand for irregular and bespoke components is accelerating.

 The opportunity for suppliers of these specialized components is substantial, driven directly by surging AI-infrastructure investment and build-out of advanced cooling and precision-machining ecosystems. From an operational and technological standpoint, Computer Numerical Control (CNC) milling dominates the precision-machining revenue mix—the exact processes at the core of ZJK’s expertise. The Company’s new chuck technology, with enhanced gripping accuracy and versatility, positions ZJK at the forefront of manufacturing irregular components for AI-servers, robotics and industrial automation. This advancement reinforces the Company’s industry leadership while accelerating its market-share gains in this high-growth segment.
