What the CNCMN-200A busbar milling machine does

The LT CNCMN-200A is a gantry-style CNC busbar milling machine that mills the corner arcs on the ends of copper busbars — the operation that rounds a bar end so it seats properly at a connection. It covers busbars from 4 to 16 mm thick, 30 to 200 mm wide and 150 to 6 000 mm long, with a six-position inline tool changer that adjusts automatically to busbar width. BT40 tool holders make tool changes quick and keep rigidity high. For UK panel shops, the practical value is that corner arcs are produced to a repeatable profile instead of being hand-finished, which is what makes the finished assembly inspectable.

Measured performance — CNCMN-200A

Test conditions: Corner arc milling on the ends of copper busbars: thickness 4–16 mm, width 30–200 mm, length 150–6 000 mm, using BT40 tool holders.

Measured values: Gantry-style structure; six-position inline tool changer adjusting automatically to busbar width; BT40 tool holders; automatic work hour counter that cannot be reset plus a resettable production counter; documentation lists 5 material thickness and width bands.

Benchmark: Machine-milled corner arcs against hand finishing: the arc profile is set by the tool path and the counter, so every bar in a batch is identical and the work is traceable.
