In the wave of industrial automation upgrading, polishing, a process requiring high precision and consistency, is gradually being taken over by polishing robots and cobot arms. As a leading provider of collaborative robot solutions, JAKA has launched two outstanding product lines—the S Series and Zu Series—to meet diverse polishing needs of different industries. Both series are high-performance cobot arms designed for industrial scenarios, but they differ in functional positioning and application focus. This article compares the two series around polishing application requirements, helping enterprises choose the most suitable cobot arm for their polishing tasks.

Core Positioning: Flexible Adaptation vs. Stable Performance

The JAKA S Series, represented by the JAKA S12, is positioned as a flexible and easy-to-deploy cobot arm for polishing. It boasts the core features of zero installation, zero configuration, and singularity protection, allowing quick deployment on polishing production lines without complex debugging, which greatly shortens the startup cycle. In contrast, the JAKA Zu Series, including models like Zu3s, Zu12s, and Zu18s, focuses on stable and high-precision performance, with a complete range of payload specifications from 3kg to 18kg, suitable for polishing tasks of different workpiece weights and sizes.

Polishing Performance: Force Perception vs. Versatile Adaptability

For polishing tasks, the JAKA S Series excels in force perception capability. The JAKA S12 is integrated with a built-in force sensor, enabling multi-dimensional force perception at the robot end, which meets the high-level demands for high adaptability, fast response, and high precision of perception technology in polishing. This allows the cobot arm to adjust polishing force in real time according to the workpiece surface, ensuring consistent processing precision and reducing the defect rate. The JAKA Zu Series is equipped with industrial force sensors (installable at the base or end) and supports three force control modes—constant force, normal tracking, and speed mode—making it competent in polishing complex surfaces and irregular workpieces, with a repeatability of ±0.02mm to ensure polishing accuracy.

Practical Application: Efficiency Priority vs. Scenario Coverage

In practical polishing applications, the JAKA S Series shows obvious advantages in efficiency and flexibility. As a polishing robot, it can replace manual operators, minimizing direct contact with hazardous processing equipment and reducing accident risks. It is highly reprogrammable, allowing users to adapt programming for different workpieces, shortening the product modification cycle and reducing associated equipment investment. The JAKA Zu Series, with its diverse payload and reach options, covers more polishing scenarios—from small precision parts to large workpieces, and its excellent MTBF ensures long-term stable operation, suitable for large-scale continuous polishing production.

Choose the Right JAKA Cobot Arm to Unlock Polishing Automation Value

Both JAKA S Series and Zu Series cobot arms are high-quality choices for polishing automation, with their own advantages to adapt to different enterprise needs. The S Series is more suitable for enterprises that pursue quick deployment, flexible adjustment, and high-precision force control in small to medium-sized polishing tasks. The Zu Series is ideal for enterprises with diverse workpiece sizes, large-scale production demands, and high requirements for long-term stability. By selecting the appropriate JAKA cobot arm according to their own polishing scenarios and needs, enterprises can effectively improve polishing efficiency, ensure product quality, and truly realize the value of polishing robot automation.
