303U-3-C 3 in 1 manual hydraulic busbar machine FAQ

Q1: What functions does the LT-303U-3-C busbar machine provide?

A: The LT-303U-3-C is a 3-in-1 multifunction busbar processing machine that can punch, cut, and bend copper and aluminum busbars. It supports round holes, oblong holes, shearing, vertical bending, flat bending, U-bending, and Z-bending through mold changes.

Q2: What is the punching capability of this machine?

A: The punching unit uses an integral six-mode turnplate to ensure upper and lower mold alignment. 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 cutting unit adopts double-column shearing dies for stable performance. It can shear copper or aluminum busbars up to 12 mm thick and 160 mm wide.

Q4: What type of bending structure does the machine use?

A: The machine uses a closed bending structure, which provides uniform force during horizontal bending and embossing, and improves repeat positioning accuracy, especially in mass production.

Q5: Can the machine be equipped with customized molds or tools?

A: Yes. Different molds or special tools can be customized based on user requirements to perform special-shaped processing.

Q6: What bending precision does the LT-303U-3-C achieve?

A: 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 is the total power of this busbar machine?

A: The machine is equipped with 3 × 4 kW power units.

Q9: What components are included in the machine?

A: Main parts include: CNC touch screen, industrial lamp, punching turret unit, positioning ruler, cylinders, cutting unit, bending unit, electrical box, line switch, foot switch, and tool box.

Q10: What after-sales service is provided?

A: Our after-sales engineers will provide regular return visits, collect customer feedback, and continuously improve machine quality. Technical guidance and support are available.

Q11: How is the busbar machine packaged for delivery?

A: The machine is wrapped with waterproof plastic film inside and packed in wooden cases outside to ensure safe transportation.

Q12: Does the LT-303U-3-C have quality certifications?

A: Yes, the product is certified with ISO9001:2000 and CE standards.

Q13: What is the overall machine dimension and weight?

A: The machine size is 1720 × 1220 × 1240 mm, the container size is 1800 × 1300 × 1450 mm, and the total weight is 1320 kg.

Q14: Is this machine suitable for transformer or switchgear manufacturing?

A: Yes. With punching, cutting, and bending in one unit, it is commonly used in transformer plants, switchgear factories, and electrical panel manufacturing.
