As demand for electrical components grew in complexity and volume, the limitations of sequential, standalone processing became apparent. The industry's answer was a move toward integration, culminating in the development of multifunctional and Computer Numerical Control (CNC) busbar machine. This evolution marked a shift from manual, process-specific tools to automated, precision-fabrication centers.

The early concept of integration is exemplified by multifunctional machines designed to combine several key processes. One such design featured a rotating swivel plate equipped with four different mold jigs, each dedicated to a specific task: rounding (fillet machining), punching, shearing, and coining (embossing or pitting). A single, centrally located pressure mechanism, often hydraulic, would act upon these different stations. This ingenious design dramatically reduced the need for multiple pieces of equipment, saving valuable factory floor space, minimizing the staff required for material handling, and boosting overall equipment utilization while cutting down on resource waste.

The true revolution, however, came with the infusion of CNC technology. Modern multifunctional CNC busbar machines represent a leap forward in automation and capability. They go beyond the basic trio of shearing, punching, and bending to incorporate more advanced and critical processes. A landmark innovation in this space is the integration of a riveting unit for laminated busbars. Laminated busbars, which are multi-layer assemblies crucial for compact, high-power distribution, require precise insertion and connection of components. Advanced CNC machines now integrate a riveting unit that can punch a groove, insert a component (like a connector pin), and then rivet it in place—all in a single, automated sequence.

This level of integration delivers profound benefits. It eliminates multiple setups and manual transfers, drastically improving machining accuracy and processing speed. The automation extends to material handling, with features like conveyor chain mechanisms and programmable clamps that move the busbar through each station without human intervention. The result is a "set-and-forget" production cell where a raw bar enters, and a finished, complex component exits, with consistency and quality levels unattainable by traditional methods. This transformation has made busbar fabrication faster, more reliable, and capable of meeting the sophisticated demands of today's power electronics.
