China CNC busbar machine
Made by MAC, multi-functional, servo automatic positioning, semi-automatic CNC, used for busbar bending, punching and cutting.
Professional CNC busbar machine manufacturer
MAC is a CNC busbar machine supplier dedicated to providing busbar manufacturers with process solutions such as bending, punching and cutting. Through the perfect design and application of servo motors and PLC systems, we have helped more customers in the power industry to achieve CNC automated busbar production. In terms of busbar production efficiency and processing accuracy, our busbar processing machine’s humanized CNC operating system is unique and well received by the market.

With the introduction of servo and roller screw, our busbar bending, punching and cutting machine has been upgraded from semi-automatic bending to fully CNC semi-automatic. Based on the multifunctional structure of the 3 in 1 busbar machine, we have installed servo stopper on the bending unit, punching unit and cutting unit, which are independent of each other, realizing the automatic positioning of the busbar processing position and simultaneous operation by three people, completely replacing the manual calibration of the busbar processing position scale, greatly improving the busbar production efficiency and accuracy.

How to buy a suitable CNC busbar machine
Our technical engineers will recommend busbar machine models to customers based on the maximum thickness and width of the busbars they process. Our 3 in 1 busbar machine has three models, equipped with 300KN, 500KN and 800KN hydraulic pumps, for processing copper busbars with a maximum of 12mm/160mm, 16mm/250mm and 20mm/300mm.
Different from our 3 in 1 busbar machine, the bending unit and cutting unit in our CNC busbar machine are each equipped with a servo stopper with an effective stroke of 1000mm, which is responsible for positioning the busbar processing position; the punching unit is equipped with two servo stoppers, namely a length servo stopper with an effective stroke of 1000mm and a width servo stopper with an effective stroke of 150mm, which are responsible for the X-axis and Y-axis coordinate positioning of the busbar punching.

What are the functions of CNC busbar machine?
Our CNC busbar machine consists of three independent working units: bending, punching and cutting. It has the functions of bending, punching and cutting. On each independent working unit, the operator can bend the copper busbar or aluminum busbar at different angles and punch holes of different shapes or sizes by replacing different dies. Each of our equipment is equipped with 5 sets of bending dies, 8 sets of punching dies, 1 set of embossing dies and 1 set of cutting dies, which can meet the processing requirements of international conventional standard copper busbars. As shown in the following table:
Punching Mold | Φ7, Φ9, Φ11, Φ13, Φ17, Φ11*15, Φ13*18, Φ17*21 |
Bending Mold | R3, R5, R10, R80 or R50, U-SHAPE Mold |
Embossing Mold | 1 Set |
Cutting Mold | 1 Set |
Twist Mold | 1 Set (Option) |
Tips: If you have a special busbar processing technology, please send the busbar drawing to our technical engineer by email. We can customize the busbar mold according to your drawing, including one-time forming bending molds and unconventional shape punching molds.

How to use cnc busbar machine?
Different from the semi-automatic busbar bending machine, the first operation of the CNC busbar machine requires the operator to visually input the busbar drawing parameters into the PLC program through the HIM mobile panel, including bending angle, busbar parameters, cutting length, punching position coordinates, etc., and store them in program memory, without repeated input each time, and can be directly called.
After ensuring that the input parameters are correct and the correct mold is selected, the operator can perform busbar processing by controlling the foot pedal switch without other manual operations.
CNC busbar punching operation
Tips: If you have sufficient budget, high requirements for automation and high busbar accuracy, we recommend that you purchase CNC busbar bending machine and CNC busbar punching and shearing machine, which support the import of 2D and 3D drawings. The two devices can share programs through LAN and WIFI. When the busbar punching and shearing are completed, there is no need to debug the busbar bending machine, and the bending can be directly operated, which greatly improves the busbar production efficiency.
In principle, the punching capacity of the same specification of punching die in different models of equipment is also different. For example, the punching capacity of Φ13 is different in different models of equipment. Even so, we still recommend that the thickness of the punching busbar should not exceed the specification value of the punching die, for example, the maximum punching thickness of the Φ7 punching die is 6mm.
Our technical engineers have given the punching capacity range of each punching die according to the different specifications of punching dies for different models of equipment. As shown in the table:
Model | MAC-303CN PRO | MAC-503CN PRO | MAC-803CN PRO |
Φ7 | 2-6mm | 2-6mm | 2-6mm |
Φ9 | 2-8mm | 2-8mm | 2-8mm |
Φ11 | 6-10mm | 6-10mm | 6-10mm |
Φ13 | 6-12mm | 6-16mm | 6-20mm |
Φ17 | 8-12mm | 8-16mm | 8-20mm |
Φ11*15 | 8-12mm | 8-16mm | 8-20mm |
Φ13*18 | 8-12mm | 8-16mm | 8-20mm |
Φ17*21 | 8-12mm | 8-16mm | 8-20mm |

Advantages of CNC Busbar Machine
Full servo automatic positioning, higher process automation.
Each unit of the copper busbar machine is equipped with a servo-driven roller screw, which can easily control the busbar processing length through the PLC system, automatically locate the busbar punching or cutting parameter coordinates, and has excellent accuracy in busbar cutting, bending and punching. This level of precision ensures that the final product meets strict quality standards, which is critical for electrical applications because accuracy is essential for safe and efficient operation.
At the same time, our CNC busbar machine can easily process different types and sizes of busbars through the PLC system and different mold combination applications, providing flexibility for various busbar manufacturing needs. This adaptability allows busbars to be customized for specific applications.


CNC full process access, the final busbar product quality consistency is higher.
Our equipment uses Siemens ST-1200 new generation CNC controller and is equipped with a mature PLC system, which can accurately control bending, punching and cutting, reduce manual intervention, and produce identical busbars with consistent quality.
With the access to CNC technology, the punching unit of our busbar processing machine supports multi-axis control, which can simultaneously control multiple axes (such as X-axis, Y-axis) to perform complex processing tasks, greatly improving busbar production efficiency. Multi-axis control makes the processing process more flexible and can handle busbars of different shapes and sizes.
