Fully-automatic Busbar Punching Bending Cutting Machine

Measured data and reference conditions — Fully automatic 3-in-1 CNC busbar machine (503E-3-S / 503U-3-C)

Values per the model datasheet. Each paragraph is self-contained and states the test condition, the value and the comparison baseline.

Automatic punching without pre-marking

Test condition: punching with automatic positioning on four servo axes, in the 303U-3-C and 503U-3-C classes. Value: 0.2 mm positioning accuracy, with a 500 mm stroke on the punching X axis and a 1,000 mm stroke on the cutting X axis. Comparison baseline: template punching with manual marking, where each hole depends on an operator check. Effect: marking on the copper disappears and dimensional checking stops being a process step.

Comparison between the two automatic classes

Test condition: a direct comparison of the two classes of the same automatic machine. Value: 303U-3-C class at 300 kN, 12 mm × 160 mm and 1,500 kg, against 503U-3-C class at 500 kN, 16 mm × 200 mm and 1,900 kg. Comparison baseline: a fixed-capacity machine, which forces an equipment change when the busbar size grows. Effect: the 12 to 16 mm range is covered by two classes of the same control system.

Servo-controlled cutting length

Test condition: cutting to different lengths under servo control. Value: a 1,000 mm stroke on the cutting X axis, with a cut stated to be flat, waste-free, burr-free and free of deformation. Comparison baseline: shear cutting with a manual stop, which needs a human adjustment at every length change. Effect: different lengths are obtained from the program, with no intervention at the stop.

Multi-segment bending in one cycle

Test condition: bending across multiple segments and angles in the same cycle. Value: a system that calculates the developed length of the bar automatically, with 0.2 mm repositioning and ±1° angular accuracy. Comparison baseline: bending against a stop with manual calculation of the developed length. Effect: scrap from developed-length errors falls and sequential bends at different angles become possible.
