MICROMETER-PRECISION ACTUATION POWERS CLEAN, HIGH-SPEED PRODUCTION
E
lectric vehicle (EV) battery cell manufacturing demands extreme precision and reliability. As manufacturers scale up output to meet soaring EV demand, production lines are incorporating advanced automation that can position components with micrometre-level accuracy while maintaining contamination-free operation. Production solutions are becoming increasingly important as the UK accelerates its transition to electric mobility.
One recent case study illustrates how Rollon’s TH Precision System linear actuators enabled a high-speed battery cell assembly line to achieve ±5 µm positioning accuracy, solve chronic

lubrication failures, and integrate seamlessly with sensor-driven quality control systems. This engineering-led solution, involving over 100 actuators, highlights the importance of precision motion components in modern instrumentation and automation for battery production.
CHALLENGES IN HIGH-PRECISION BATTERY CELL AUTOMATION In high-volume battery cell production, even minor mechanical shortcomings can impact yield and throughput. In this case, a leading battery manufacturer (via its automation OEM partner)
encountered four key challenges hindering its existing production line: accuracy, stiffness, compactness, and lubrication. The line’s previous actuators were inconsistent and plagued by lubrication problems, leading to unplanned downtime and throughput loss. Ineffective lubrication had caused actuators to seize or slow down, interrupting the flow between workstations and negatively affecting cycle time, efficiency, and yield. The OEM integrator needed to resolve these lubrication failures and ensure consistent, repeatable motion.
The battery manufacturer required an
