Purpose-engineered for high-volume architectural aluminum fabrication, this 4-meter CNC machining center redefines efficiency in long-profile processing. Unlike conventional short-bed machines that rely on repeated repositioning, it executes full-length drilling, tapping, milling, and slotting in a single cycle—eliminating cumulative errors and guaranteeing flawless linear accuracy across every meter. Powered by a high-speed electrospindle, a seamless automatic tool changer (ATC), and servo-driven clamping, it delivers ±0.1mm precision with industrial-grade repeatability. Designed for manufacturers who refuse to compromise between throughput and quality, it slashes labor dependency, minimizes material handling, and provides the ultimate scalable solution for system windows, premium façades, and curtain wall systems.

This CNC double-head precision cutting saw is designed for simultaneous 45° mitre and 90° square cutting of aluminum profiles, thermal break aluminum windows, and UPVC/PVC profiles. Equipped with two independent CNC-controlled saw heads, it cuts both ends in one cycle — doubling throughput while ensuring perfect angle matching for corner joints. Features servo-driven length positioning (±0.02 mm repeatability), Ø500–550 mm carbide blades, pneumatic clamping, and a user-friendly 7" touchscreen. Heavy-duty steel frame ensures long-term cutting stability. Ideal for high-volume window, door, and curtain wall fabrication. CE certified, 12-month warranty, global technical support.
