High-Precision CNC Busbar Milling Machine | Automatic Copper Bar Chamfering & Edge Rounding Solution

Superior Edge Finishing for High-Voltage Reliability. Sharp edges on busbars are a major risk for electrical discharge. Our CNC Milling Machine provides the perfect "R-angle" to ensure long-term insulation safety and professional aesthetics.

Core Technical Advantages:

• Natural Language Programming: No complex CNC coding required. Operators can input parameters through simple commands, drastically reducing training time and setup errors.

• Automatic Tool Magazine: Seamlessly switches between different milling cutters to achieve various R-angles or flat surfaces in one continuous cycle without manual intervention.

• Boosting Clamping Function: High-pressure automated clamping ensures the copper bar remains perfectly stable during high-speed milling, resulting in a mirror-like surface finish.

• Precision R-Angle Rounding: Delivers consistent, burr-free edges that comply with the strictest global high-voltage engineering standards (IEC/IEEE).

• High-Volume Consistency: The intelligent PLC control system guarantees that the 1,000th busbar is as precise as the first one, essential for large-scale switchgear projects.

Strategic Impact:

• Eliminate Partial Discharge: Directly improves the safety rating of your switchgear panels.

• Reduce Skill Dependency: Standard operators can produce master-level precision results.

• Enhanced Aesthetics: Provides a premium, high-end look to your internal busbar systems.

4.1 Applicable specifriistics This machine is suitable for processing the cross-sectional arc of the busbar with a thickness ≤ 12mm, width ≤ 200mm, and length ≥ 160mm. 

4.2 Arc Types In response to the current regulations on the design of the busbar, there are four standard modes available on the control interface: semicircle, arc, oblique angle, and fillet.

4.3 Mother row clamping The fixture has the function of automatic centering of the busbar, so as to keep the pressure head at a reasonable point of action and achieve automatic clamping once. 

4.4 Boosting clamping The pressure head adopts a booster structure, which makes the workpiece clamping more stable and the machining surface effect better. 

4.5 Automatic tool magazine The equipment has an automatic tool magazine and can be pre configured with 4 forming circular arc cutting tools. Adopting the international standard BT40 handle, one click tool change is available according to different processing requirements, making it simple and fast.

4.6 Transmission System The ball screw and linear guide of the transmission system both use high-speed and high load components to ens ure good dynamic characteristics of the motion pair and machining quality. 

4.7 System ConfigurationThe components of the control system are all from well-known international and domestic brands. To ensure the stability and reliability of the overall performance of the system.

4.8 Human Machine Performance The system operating program is our company's proprietary technology, with an intuitive and clear human- mach ine interface and natural language programming. Even if you don't understand CNC G code, you can proficiently maste r the use of the equipment in a short period of time. Parameterized programming in human-computer interaction enviro nments can not only simplify the programming process, but also avoid input errors in manual programming. 

4.9 Safety Protection The rotating components of the equipment are designed with full protection, ensuring safety and reliability

4.10 processing quality The surface roughness of the processed busbar can reach Ra1.6, with no pointed discharge. The use of end arcs and chamfers can reduce the spacing between busbar arrangements. Therefore, more cabinet design space can be relea sed.
