CNC Busbar Chamfering Machine LT-CNCMN-200A
Ideal for LV/HV switchgear factories, panel shops, transformer plants and busduct production lines that require smooth, standard-compliant copper bar edges.
Quick Summary
The LT-CNCMN-200A removes the manual deburring step that Thai busduct and switchgear shops usually leave to hand grinding: a 5-axis CNC gantry chamfers and arc-mills copper and aluminium bar ends from 4 to 16 mm thick, 30 to 200 mm wide and 150 to 6,000 mm long, holding ±0.08 mm in X/Y and ±0.05 mm in Z. A 6,000 rpm spindle with a 6-station BT40 tool changer (4-12 mm cutters) leaves clean, burr-free edges, and the 10.4-inch control stores programmes, counts parts and simulates the path. It needs 0.6-0.8 MPa compressed air and 12 kW total power.

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.
Edge accuracy on bar ends
Test condition: chamfering and arc milling of copper or aluminium bar ends 4-16 mm thick and 30-200 mm wide on a rigid gantry. Result: ±0.08 mm X/Y positioning accuracy and ±0.05 mm Z positioning accuracy with a 6,000 rpm spindle. Baseline: the HQ600-SP punching and shearing machine positions to 0.10 mm over 500 mm, so the chamfering unit works to a finer ±0.05-0.08 mm band.
Workpiece envelope
Test condition: handling the full spread of busbar sizes used in Thai busduct and panel work. Result: 4-16 mm thickness, 30-200 mm width and 150-6,000 mm length in one machine, with 525 mm X-axis travel at up to 15 m/min and 130 mm Z-axis travel. Baseline: the HQ600 series processes 6,000 x 200 x 15 mm, so both machines share the same 6,000 mm length and 200 mm width envelope.
Tooling, power and utilities
Test condition: continuous chamfering duty with automatic tool changes between operations. Result: 6-station BT40 automatic tool changer taking 4-12 mm cutters, 3.7 kW main motor, 2 kW X/Y servos, 1 kW Z servo, 2 kW hydraulic pump, 12 kW total, at 0.6-0.8 MPa air. Baseline: against manual hand deburring there is no published figure - the measurable gain is programme-repeated edge geometry instead of operator-dependent grinding.
Where does this machine save work?
It removes manual deburring and edge-finishing, keeping the production line moving.
Can it switch between chamfer sizes often?
Yes. The 6-station magazine changes tools automatically and supports 4/5/6/8/10/12 mm cutters.
How long can the bars be?
150–6,000 mm. Both ends of long bars can be processed with stored programs and automatic work counting.
What kind of structure does it use?
A gantry structure with a fully welded steel plate box design, offering high rigidity and stable operation.
Is manual tool changing needed?
No. The six-station inline magazine changes tools automatically with BT40 holders.
