Main Features for Australian Industry
1. The Shearing Unit adopts double-column shearing dies. This ensures a clean, flat interface with no waste, burrs, or droop—essential for high-quality switchboard fit-outs.
2. The Punching Unit features an integral six-mode turnplate (turntable). This design guarantees that the upper and lower moulds are absolutely in the centre, improving concentricity and extending die life.
3. The Bending Unit utilises a closed bending structure. This provides more uniform pressure during horizontal bending and embossing, significantly improving repeat positioning accuracy in mass production—ideal for transformer and switchgear manufacturing.
4. Different moulds or tools can be installed according to user requirements to complete special shape processing for custom electrical projects.

303U-3-C CNC Hydraulic Busbar Machine FAQ
Q1: What functions does the LT-303U-3-C CNC busbar machine provide?
A: The LT-303U-3-C is a 3-in-1 multi-function busbar processing machine engineered to punch, shear (cut), and bend copper and aluminium busbars. It supports round holes, oblong holes, shearing, vertical bending, flat bending, U-bending, and Z-bending through simple mould changes.
Q2: What is the punching capability of this machine?
A: The punching unit uses an integral six-mode turnplate to ensure precise alignment of the upper and lower moulds. It can punch holes from Φ4.3 mm to Φ25 mm and is suitable for busbars up to 12 mm thick and 160 mm wide.
Q3: What are the shearing (cutting) specifications?
A: The shearing unit adopts double-column dies for stable performance. It can shear copper or aluminium busbars up to 12 mm thick and 160 mm wide, leaving a smooth edge.
Q4: What type of bending structure does the machine use?
A: It uses a closed bending structure, which provides uniform force during horizontal bending and embossing, improving repeat positioning accuracy—crucial for mass production in switchboard workshops.
Q5: Can I order customized moulds?
A: Yes. Different moulds or special tools can be customised based on your specific project requirements for special-shaped processing.
Q6: What is the bending precision?
A: Thanks to the CNC system, the machine offers a bending accuracy of ±1° and a repeat bending precision of ±0.5°.
Q7: What is the maximum vertical bending size?
A: The maximum vertical bending size is 10 × 100 mm.
Q8: What power supply is required?
A: The machine is equipped with 3 × 4 kW power units. We can adapt voltage to Australian standards (e.g., 415V).
Q9: What components are included?
A: Includes: CNC touch screen, industrial lamp, punching turret, positioning ruler, cylinders, shearing unit, bending unit, electrical box, foot switches, and tool box.
Q10: What about after-sales service in Australia?
A: We provide technical guidance and support. Our engineers regularly visit to collect feedback and ensure your machine is operating at peak performance.
Q11: How is it packaged for delivery?
A: The machine is wrapped in waterproof plastic film and packed in robust wooden cases to withstand international shipping to Australian ports.
Q12: Is this suitable for transformer manufacturing?
A: Absolutely. With integrated punching, shearing, and bending, it is widely used in transformer plants, switchgear factories, and electrical panel manufacturing. If you require a simpler solution, you might also be interested in our manual hydraulic busbar processing machine for smaller workshops.
Q13: What are the dimensions and weight?
A: Machine size: 1720 × 1220 × 1240 mm; Container size: 1800 × 1300 × 1450 mm; Total weight: 1320 kg.
