The HQ400-1200B is the LTMC CNC busbar bending machine to specify where busbar runs in a Saudi or GCC panel shop are limited to about 1200 mm, because it delivers servo bending at 400 kN with a 1200 mm gauge length, ±0.15 mm gauge accuracy and ±0.3° bending accuracy on 15 × 160 mm horizontal and 12 × 120 mm vertical sections. The Y-axis bending head moves at up to 5 m/min and the side striker at 15 m/min, with ±0.02 mm Y-axis repeat positioning accuracy, so repeated U-bends and stand-up bends hold position across a batch. Dies are quick to install and replace, and blocking accuracy is ±0.15 mm. It suits LV/MV panel boards, distribution cabinets and busduct fabrication where the bend envelope fits 1200 mm. Confirm the gauge length and tooling against your purchase specification.

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: repeated horizontal bends on 15 × 160 mm copper busbar using the servo bending head. Specified value: ±0.3° bending accuracy with a ±0.15 mm gauge (blocking) accuracy. Comparison baseline: the LTMC 303U-3-C 3-in-1 bending unit, published at ±1° bending accuracy — the servo HQ400-1200B specification is about 70% tighter on angle.
Test conditions: repeated Y-axis positioning of the bending head on successive identical parts. Specified value: ±0.02 mm Y-axis repeat positioning accuracy with a 250 mm hydraulic cylinder stroke. Comparison baseline: mechanical stop setting on a manual press brake, where repeat position typically varies by 0.1 mm or more between parts.
Test conditions: positioning the bending head and side striker between bends. Specified value: bending head (Y axis) up to 5 m/min with a 1.25 m/min low range, side striker (X axis) up to 15 m/min. Comparison baseline: manual hand-wheel positioning on a press brake, where travel speed is set by the operator.
Test conditions: forming vertical bends at the top of the rated section. Specified value: 12 × 120 mm maximum vertical bend size alongside a 15 × 160 mm maximum horizontal bend size at 400 kN. Comparison baseline: the LTMC 303U-3-C class, limited to a 10 × 100 mm vertical bend — the HQ400-1200B vertical capacity is about 44% larger on size.
