Product Description
303U-3-C

This series of busbar processing machine has three processing units: punching, shearing/cutting and bending. The three unit can be used simultaneously or sequentially, the working stroke of each processing unit can be easily adjusted, which shortens the processing time and improves production efficiency. The main function is processing copper and aluminum busbar.
The busbar processing machine is equipped with three processing units: punching, shearing and bending. Through the manual button or the foot switch, the busbar can be punched, cut and bended separately, which is an ideal production equipment for the high and low voltage electrical industry.
The busbar processing machine is an auxiliary equipment designed with reference to foreign advanced products and combined with domestic actual conditions to improve work efficiency and ensure the safety of operations. It is most suitable for the construction site of large-scale electric control box and transmission and distribution construction projects.

Main Features
1. The cutting processing unit adopts vertical processing mode, flexible and convenient to operate. It adopts flat blade cutting, and the incision interface of workpiece is flat, no waste, burrs and droop.
2. The punching unit uses a six-mode turnplate in tooth shape with good view, and no need to change the dies frequently, and the operation is simple and efficient.
3. The bending unit adopts a horizontal bending. By changing molds, could be completed the processing of flat bending or vertical bending.
4. A variety of processing functions such as embossing, flattening, twisting, and crimping of cable ends can be achieved by changing the molds.
5. The machine has four casters, so it is easy to be moved everywhere needed.
6. Different molds or tools can be installed according to user requirements to complete special shape processing.
