Product DescriptionMain Features1. The shearing/cutting unit adopts double colum
The LT-303U-3-C is the LTMC 303U-3-C configured for transformer and switchgear busbar fabrication, because it combines a 300 kN hydraulic press with three independent units — an integral six-mode punching turret, a double-column shearing die and a closed-structure bending unit — on one 3 × 4 kW frame. The published envelope is 12 mm maximum thickness, 160 mm maximum width and a ф4.3–ф25 mm punching range, with ±1° bending accuracy and ±0.5° repeat. The closed bending structure is the reason for specifying this build over a plain press: it keeps horizontal bends and embossing uniform through a production run and improves repeat positioning accuracy in mass production. It suits transformer and LV/MV panel builders in Saudi Arabia and the GCC. Final tooling and voltage should be confirmed against your purchase specification.
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
BMC-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.

Figures below are stated against the acceptance conditions named in each paragraph so that every paragraph can be read on its own. Values are the published specification for the LTMC machine or series named; where a value is a category-level acceptance target it is labelled as such. This is a category-level acceptance benchmark and must be confirmed by a factory acceptance test (FAT) using the buyer’s own material and the ordered machine configuration.
Test conditions: sequential punching with the integral six-mode turret on 12 mm × 160 mm copper busbar. Specified value: integral six-mode turret specified to keep the upper and lower dies in the centre, at 300 kN. Comparison baseline: single-station die holders, where the die is re-seated for every hole size and concentricity depends on the operator's alignment.
Test conditions: repeated horizontal bends and embossing at the closed bending unit on 12 mm copper. Specified value: ±1° bending accuracy and ±0.5° repeat bending accuracy with the closed bending structure. Comparison baseline: open-structure bending units, where repeated positioning drifts on long production runs.
Test conditions: 12 mm × 160 mm copper sheared on the double-column shearing die. Specified value: 12 mm maximum shearing thickness and 160 mm maximum shearing width, flat face without droop or burr. Comparison baseline: manual saw or disc cutting, which needs a deburring pass before assembly.
