Product DescriptionMain Features1. The shearing/cutting unit adopts double colum
The LTMC 303U-3-C is a 300 kN CNC 3-in-1 busbar machine that punches, shears and bends copper and aluminum busbar for Canadian panel shops building switchgear, control panels and transformer links. Its integral six-mode punching turret keeps upper and lower dies centered for clean round and oblong holes up to 25 mm, while the closed bending structure holds ±1° with ±0.5° repeatability on bars up to 12 mm thick by 160 mm wide. At 1320 kg and 1720×1220×1240 mm it fits a compact fabrication cell, and it carries ISO9001:2000 and CE marks for shops documenting quality systems. Standard LJMC tooling and changeable molds cover special shapes without custom fixtures.
303U-3-C — Nominal force: 300 kN. Test condition: three-pump hydraulic drive on punch, shear and bend units. Result: 300 kN rated force for busbar up to 12 mm thick. Baseline: 503U-3-C at 500 kN and 803U-3-C at 800 kN in the same family (family_ref.txt), so the 303U-3-C is the entry model for lighter gauge work.
303U-3-C — Maximum busbar size: 12 mm thick × 160 mm wide. Test condition: copper/aluminum bar through punch, shear and bend. Result: 12 mm thickness, 160 mm width. Baseline: 803U-3-C processes 20×250 mm (family_ref.txt); the 303U-3-C covers standard switchgear busbar while the 803U-3-C handles heavy transformer links.
303U-3-C — Punching diameter range: 4.3–25 mm. Test condition: six-mode turnplate punching round and oblong holes. Result: 4.3–25 mm diameter. Baseline: 503U-3-C 4.3–30 mm and 803U-3-C 4.3–34 mm (family_ref.txt); the 25 mm top suits typical lug and connector holes.
303U-3-C — Bending precision: ±1° (repeat ±0.5°). Test condition: closed bending structure, horizontal/vertical/U/Z bending. Result: ±1° angle, ±0.5° repeat. Baseline: matches 503U-3-C and 803U-3-C (family_ref.txt); same angle control across the family.
303U-3-C — Power and weight: 3×4 kW, 1320 kg. Test condition: three-pump hydraulic system. Result: 12 kW installed, 1320 kg. Baseline: 803U-3-C 3×5.5 kW / 2100 kg (family_ref.txt); lighter and lower power for smaller shops.
It runs on a 3×4 kW three-pump hydraulic system fed from your 600 V, 60 Hz service through a transformer. Confirm the exact incoming supply and disconnect rating with our team.
The 303U-3-C carries ISO9001:2000 and CE marks and is specified for busbar going into assemblies built to CSA C22.2 in Canada and UL in the US. Share your AHJ component and wiring checklist and we will confirm the build options for your shop.
Standard LJMC tooling and changeable molds cover common holes and bends, and training is arranged around installation. Confirm spare-part stock and on-site training scope with our team for your region.
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.

Processing Samples
LTMC-303U-3-C is a three functions busbar processing machine.
Function one: punch
For round hole punch, oblong hole punch.

Function two: cut

Function three: bend.
It can do vertical bending, flat bending, U-bending, and Z-bending by changing the molds.
