303E-3 is a 3-in-1 busbar machine for shearing, punching and bending copper and aluminium busbar. It suits workshops with small and medium batches where three separate machines have neither space nor utilisation. All three operations run in one machine with quick-change tooling. Delivery includes the CE declaration, installation, operator training and a 12-month warranty.
Test conditions: Copper Cu-ETP (99.9% Cu), busbar 10 x 100 mm, shearing plus 12 mm punching plus 90 degree bending, workshop temperature 20 °C, one-off and small batch run of 30 pieces.
Measured values: Punching force 300 to 500 kN depending on station, position deviation ±0.15 mm, angle deviation ±0.3°, setup time between operations 30 s, total part time 4.5 min.
Comparison baseline: Baseline: three separate machines, setup time 6 min, total part time 11 min, two operators.
303E-3 busbar punching shearing bending busbar shear machine

Main Function:
To cut/punch(all kingds of round/square/special holes and slot type)/chamfer/horizontal bending/vertical
bending/ emboss/Press cable thread /twist/anti-press flat the copper/aluminum busbar ect.
Function Introduction
●● 1. Cutting unit adopts double-column shear structure (patent number: ZL201120262802.1),Cut mouth flat, no
burr, no waste.
●● 2. Punching unit adopts Nodular cast iron,4/6/8 modes position turrent punching structure which is a totaly
whole one,improving concentric degree of moulds,prolonging the service life of the moulds,saving time of
change.
●● 3. Bending unit adopts closed bending structure,making it is more uniform when processing horizontal bending
and embossing. Also prolonging the service life.
●● 4. Bending unit adopts double work table,achieved a real sense of the three position working at thge same time
while working without impact each other.
●● 5. Adopting PLC controlled,compared to the traditional relay,more stable and reliable.
●● 6. Three units of the machine can work at the same time,not affecting each other,Improving the processing
efficiency.
●● 7. Hydraulic tank with thick plate welding,and is treated by phosphating, making hydraulic oil can be long time
used and will not degenerate.
