Joint Connection Bar Processing Center
Customizable CNC System for Precision Punching, Counter-Boring, Cutting, and Multi-Angle Folding
Traditional busbar punching and bending often lead to misaligned bolt holes. KIANDE joint connection bar processing center ensures every component fits perfectly the first time. We use integrated CNC technology to master the most complex connection shapes.
Our process starts with high-speed automated feeding for raw copper bars. This is followed by multi-unit CNC punching and precise shearing according to your specific joint designs. The final stage integrates heavy-duty hydraulic folding and shaping with real-time accuracy compensation.
KIANDE systems control joint tolerances strictly (as tight as ±0.1mm). This precision ensures perfect hole-to-hole alignment for secure bolt fastening and low contact resistance. Our CNC busbar punching machine enables stable, 24/7 high-output production for various connection shapes. You can get maximum fabrication capacity with minimal labor dependency.

How do you prevent surface scratches on plated copper bars?
We use specialized rollers and polished die coatings to protect tin or silver plating. This ensures the lowest possible contact resistance and prevents oxidation during the bar's service life.
