3+1 Axis CNC Aluminum End Milling Machine for Thermal Break Window Mullion

G50 CNC Machining Center for 6.8m aluminum profile fabrication. Features 18-axis servo, 3-head 90° & 45° cutting, 4-side milling, dual 2KW lasers. Handles thermal break profiles with ±0.1mm accuracy, 60% higher labor efficiency.

The 3+1 axis CNC end milling machine is designed for end processing of thermal break aluminum window mullions, transoms, and frame profiles. It combines fixed-angle cutting at +45°, 90°, and -45° using diamond saw blades with dual-laser drilling and scribing on both front and rear faces. Electric spindles positioned on four sides (front, rear, top, and bottom) handle drilling and milling operations in a single clamping cycle. Common applications include tenon and groove cutting, step face machining, chamfering, and notch work for high-volume aluminum door and window production lines.

The machine runs on 380V 3-phase power with a total rating of 4 kW, including a 3 kW spindle operating at 2800 rpm. Diamond blade diameters range from φ230 to φ300 mm, and maximum milling depth is 70 mm. Workable profile dimensions are up to 120 mm in width and 150 mm in height. Overall machine footprint is 1500 × 800 × 1400 mm, with a weight of approximately 400 kg. Working air pressure is maintained between 0.5 and 0.8 MPa.

Lebulang Machine, a China-based manufacturer with nearly 30 years of factory experience in aluminum profile processing equipment, produces this end miller. CE and ISO certification is available. Custom OEM configurations are supported, and the equipment is supplied on a factory-direct basis. The design emphasizes ease of maintenance, and remote installation guidance is provided without additional charge.
