High-Precision 4-Axis CNC Friction Stir Welding Machine for Aluminium and Copper Alloys

Description

The High-Precision 4-Axis CNC Friction Stir Welding Machine is an industrial welding system designed for aluminium-alloy and copper-alloy components requiring controlled movement, repeatable positioning and consistent weld quality. The machine provides 1200 mm X-axis travel, 700 mm Y-axis travel and 600 mm Z-axis travel. Its 1200 × 700 mm T-slot working table supports workpieces weighing up to 1500 kg, making the unit suitable for large panels, cooling plates and fabricated metal components. An 18.5 kW spindle operates at up to 3000 rpm and delivers a maximum forging force of 4 tons. Welding speed is adjustable from 0 to 2000 mm/min, while rapid traverse speeds reach 18,000 mm/min on the X and Y axes and 8,000 mm/min on the Z axis. The XYZC servo-controlled motion system uses direct transmission for the X and Y axes, with reducer transmission on the Z and C axes. The C axis supports continuous rotational positioning, while the manually adjustable B axis provides approximately ±5° of angular adjustment. The machine supports straight-line welding, butt welding and two-dimensional planar-curve welding. It is suitable for producing battery cooling plates, heat-exchanger panels, aluminium structures and other precision components.
