The LTMC CNCMN-200A is a high-speed CNC busbar milling machine designed for perfect edge chamfering & radius milling of copper/aluminum bars. Ensure burr-free edges for CSA-compliant switchgear fabrication. Ideal for North American panel shops and hydro-power distribution projects. Request a quote!
The LTMC CNCMN-200A is a single-head CNC busbar milling and chamfering machine built for Canadian switchgear and transformer shops that need burr-free corner arcs on copper and aluminum bars. It handles busbar widths of 30–200 mm, thicknesses of 4–16 mm and lengths of 150–6000 mm, making it suitable for standard panel and busway conductors. A six-position inline tool changer with BT40 holders and a two-axis CNC system keep setups quick and maintenance simple, while the gantry structure delivers the rigidity needed for consistent edge quality on CSA-compliant assemblies.
CNCMN-200A — Processing width range: 30–200 mm. Test condition: copper/aluminum busbar fed through the gantry milling head. Result: busbar widths from 30 mm to 200 mm are accepted for corner-arc milling. Baseline: matches the CNCMN-200A single-head row in family_ref.txt (30–200 mm); the Canada-version CNCMN-200A page (aid 201) publishes the same 30–200 mm width.
CNCMN-200A — Processing thickness range: 4–16 mm. Test condition: corner-arc milling of busbar ends. Result: thicknesses from 4 mm to 16 mm are handled. Baseline: matches the CNCMN-200A single-head row in family_ref.txt (4–16 mm); the Canada-version page (aid 201) lists a wider 3–20 mm window, but that figure is not claimed for this page.
CNCMN-200A — Processing length range: 150–6000 mm. Test condition: bar length for end-corner milling. Result: lengths from 150 mm to 6000 mm are supported. Baseline: matches the CNCMN-200A single-head row in family_ref.txt (150–6000 mm); consistent with the gantry structure described in the source.
The mill runs from its two-axis CNC control; the exact incoming voltage and any transformer requirement depend on your facility. Confirm the supply specification for your shop with our team when you request a quote.
Yes. The CNCMN-200A produces the burr-free, radius-accurate edges busbars need inside switchgear and panelboard assemblies built to CSA C22.2. Share your radius and documentation requirements and we will confirm the build for your shop.
Tool changes use standard BT40 holders with a six-position inline changer, and spare cutters plus operator training are available. Confirm cutter stock and commissioning lead times with our team.
Product :
CNC Busbar Milling Machine
Serial：CNCMN-200A
Main Function:
The main function of the busbar arc machining center is to mill comers (arcs) on the ends of copper
and aluminum busbars.
Main Feature:
It is mainly used for milling comner arcs on busbars with a thickness of 4-16mm, width of 30-200mm, and length of 150-6000mm.
It features a gantry-style structure, simple design, smooth operation, and good structural rigidity.
It is equipped with a six-position inline tool changer, automatically adjusting tool changes based on busbar width.
It features an automatic work hour counter that cannot be reset, along with a production counter that can be reset.
The machine uses BT40 tool holders for easy tool change, high rigidity, and precision.
A two-axis CNC system is used, offering simple operation and easy maintenance.
It supports simulated operation and manual online programming.
