CNC Busbar Bending Machine HQ400-2000B
Ideal for busduct factories and large power distribution assemblies that bend long bars and want to eliminate workpiece joints.
Quick Summary
Take the HQ400-2000B when long bars are the constraint: its 2,000 mm gauge length bends a long copper bar in one pass, which removes the joints that Thai busduct and large distribution-panel builders otherwise have to splice. Accuracy is unchanged from the 1200B - ±0.15 mm gauge, ±0.3° angle and ±0.02 mm Y-axis repeat - because it uses the same servo main drive and closed bending frame, and it handles 15 x 200 mm flat and 12 x 120 mm vertical bending at 400 kN. The cost is floor space: 4,300 mm long and 3,300 kg.

Reference Figures by Test Condition
Values below are the manufacturer's nominal figures for the stated condition. Each paragraph is written as condition + value + comparison baseline so it can be quoted on its own. Baseline machines are other models in the same LTMC catalogue; these are factory specification figures, not third-party laboratory reports.
One-pass bending of long bars
Test condition: bending a long copper bar in a single pass without re-clamping or re-positioning, at 400 kN. Result: 2,000 mm maximum gauge length with 15 x 200 mm flat bending and 12 x 120 mm vertical bending. Baseline: the HQ400-1200B is limited to a 1,200 mm gauge, so the 2000B adds 800 mm (+67%) of one-pass length and removes the intermediate joint.
Accuracy retained at the longer gauge
Test condition: CNC bending at full 2,000 mm gauge with a servo main drive and closed bending frame. Result: ±0.15 mm gauge accuracy, ±0.3° angle accuracy, ±0.02 mm Y-axis repeat, on a 250 mm hydraulic cylinder stroke. Baseline: identical figures to the HQ400-1200B - the longer bed buys length, not tighter tolerance.
Floor space and weight cost
Test condition: installation in a busduct or large panel production bay. Result: 4,300 x 1,450 x 1,850 mm machine at 3,300 kg with a 5.5 kW main motor. Baseline: the HQ400-1200B is 3,500 mm long and 3,100 kg, so the 2000B needs 800 mm more floor length and 200 kg (6.5%) more weight for 67% more gauge length.
Is it suitable for long busduct bars?
Yes. This model is specifically designed for long bars and busduct production.
Does it support batch bending files?
