EMAC-BP-40

EMAC-BP-40 is a CNC punching and shearing machine for copper and aluminium busbar up to 6000 × 205 × 12 mm. Both the punching and shearing units develop 400 kN. The machine runs at up to 150 hits per minute, carries five punch tool sets and one shear set, and holds a hole pitch accuracy of ±0.20 mm/m across three controlled axes. Maximum punched hole diameter is 32 mm and minimum oddment length is 55 mm. Installed power is 15.7 kW. The machine reads 3D and 2D drawing files directly, so no separate programming step is required, and it is shipped fully assembled and commissioned.

How is the required press force determined?

Sizing follows the worst case rather than the average: the largest hole the machine will ever punch, in the thickest and hardest bar it will ever run. Punch force is the hole perimeter multiplied by material thickness multiplied by shear strength. The punching force calculator performs the arithmetic and shows which machines clear the result.

What is the difference between the three shear modes?

Punch shear removes a slug and leaves two finished ends but consumes bar. Single shear cuts in one stroke with no material loss but leaves a small burr direction to manage. Saw cutting is slowest and leaves the cleanest edge, which matters when the cut face becomes a joint.
