Product DescriptionMain Features1. The shearing/cutting unit adopts double colum
The LTMC 303U-3-C is a 3-in-1 CNC busbar processing machine that combines punching, shearing and bending in a single unit, built for switchgear builders, panel shops and transformer manufacturing. It processes copper (C11000/Cu-ETP) and aluminium busbars, with nominal force of 300 kN. Repeatability is held across production runs and the machine integrates with CAD/CAM workflows for switchgear builders. It is built in a 20,000 m2 plant in Jinan, China with more than 100 machining units, with CE certification and IEC/UNE compliance, and exported to more than 50 countries with commissioning, operator training, spare parts and continuous technical support.

Product Description
Main Features
1. The shearing/cutting unit adopts double column shearing dies.
2. The punching unit is an integral six-mode turnplate, which ensure the upper and lower molds are absolutely in the center.
3. The bending unit adopts a closed bending structure, which makes it more uniform during processing horizontal bending and embossing, and improves the repeat positioning accuracy in mass production.
4. Different molds or tools can be installed according to user requirements to complete special shape processing.
