The LT CNCMN-200A is a high-speed CNC busbar chamfering and edge-milling center built for Canadian switchgear, transformer and busway shops that need burr-free, radius-accurate edges on copper and aluminum bars at volume. It processes widths of 30–200 mm and thicknesses of 3–20 mm with chamfering radii from R2 to R10, driven by an 8000–12000 rpm spindle at ±0.1 mm positioning accuracy. A 7.5 kW drive and 1800 kg frame, with Yaskawa/Panasonic servos and HIWIN rails, support transformer options for 208 V, 480 V and 600 V three-phase shop power.
CNCMN-200A — Processing width range: 30–200 mm. Test condition: copper/aluminum busbar width at the milling head. Result: 30–200 mm width processed for edge radiusing. Baseline: matches the CNCMN-200A Canada-version row in family_ref.txt (30–200 mm); the single-head page (aid 140) lists the same 30–200 mm.
CNCMN-200A — Processing thickness range: 3–20 mm. Test condition: busbar thickness for chamfering. Result: 3–20 mm thickness handled. Baseline: matches family_ref.txt Canada-version row (3–20 mm); wider than the single-head page (aid 140) which lists 4–16 mm.
CNCMN-200A — Chamfering radius: R2–R10. Test condition: edge radiusing and deburring of conductor ends. Result: chamfer radii from R2 to R10, customizable per program. Baseline: this radius window is defined by the model on this page; no narrower, number-comparable sibling is published on the site.
CNCMN-200A — Spindle speed: 8000–12000 rpm. Test condition: hardened tungsten-carbide cutters on copper and aluminum. Result: spindle runs 8000–12000 rpm. Baseline: matches family_ref.txt Canada-version row (8000–12000 rpm); the single-head page (aid 140) does not publish spindle speed.
CNCMN-200A — Positioning accuracy: ±0.1 mm. Test condition: CNC positioning of the busbar for chamfering. Result: positioning held to ±0.1 mm. Baseline: matches family_ref.txt Canada-version row (±0.1 mm); tighter than the 3-in-1 family, e.g. the 303E-3-S lists repeat accuracy of ±0.3°/±0.5° (a different, angle-based metric).
Yes — transformer options cover 208 V, 480 V and 600 V three-phase at 60 Hz to match your facility supply. Confirm your incoming voltage when ordering so we size the transformer correctly.
Yes. The CNCMN-200A delivers burr-free, radius-accurate edges for busbar used inside switchgear and panelboard assemblies built to CSA C22.2. Share your radius range and documentation needs and we will confirm the build.
Edge-milling cutters are hardened tungsten carbide, servos are Yaskawa/Panasonic and rails are HIWIN; spare cutters, replacement pins, commissioning and operator training are available. Confirm spare-part lead times with our team.

| Component Name | Brand / Quality Standard | Industrial Advantage |
|---|---|---|
| CNC Control System | Delta / Mitsubishi | High-speed multi-axis coordination |
| Edge Milling Cutters | Hardened Tungsten Carbide | Ultra-long service life for copper/aluminum |
| Servo Motors | Yaskawa / Panasonic | Zero-backlash precision positioning |
| Linear Guide Rails | HIWIN (Heavy Duty) | High rigidity for vibration-free milling |
| Why is automated chamfering critical for Canadian electrical compliance? | Manual grinding is inconsistent. CNC chamfering ensures every radius meets the insulation requirements for arc-flash prevention, which is vital for CSA-certified switchgear assemblies. |
| How does the machine handle dust and metal chips? | The system features an integrated high-volume chip extraction port that connects to standard industrial vacuum systems, keeping your shop floor clean and compliant with health and safety regs. |
| Can this machine process non-standard busbar sizes used in custom panels? | Yes. The CNCMN-200A allows for easy programming of custom widths and radii via the touchscreen, making it ideal for the custom "one-off" jobs common in Canadian electrical shops. |
| What are the power requirements for North American installation? | We provide transformer options for 208V, 480V, and 600V (3-phase) to ensure the machine integrates perfectly with your facility's existing electrical infrastructure. |
