CNC Servo End Milling Equipment for Unitized Curtain Wall Fabrication for unitized curtain wall aluminum profile fabrication, this CNC servo end milling equipment delivers high-precision end face milling, tenon cutting, notch grooving, and angle processing. It is the core automated machine for factory prefabrication of unitized curtain wall panels, ensuring seamless assembly and structural accuracy of curtain wall systems. Equipped with a full servo drive system and CNC control, it meets the demands of high-efficiency, Our Lebulang brand is the high-quality batch production for modern architectural facades.

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.

.Purpose-built for architectural aluminum and façade manufacturers, this advanced 3+2 axis CNC end miller solves the industry’s most persistent challenge: achieving flawless end-milling on complex, irregular mullion profiles. By integrating three high-rigidity CNC axes with a tilting spindle, it executes multi-angle face milling, step-cutting, and chamfering in a single setup—eliminating cumulative positioning errors and guaranteeing seamless, gap-free assembly in premium system windows and curtain walls. With servo-driven accuracy (±0.1mm), automatic tool calibration, and intelligent program storage, it drastically reduces labor dependency, scrap rates, and changeover times, making it the definitive solution for both high-mix custom projects and high-volume production lines.

The 400mm Double Head Cutting Saw is a professional profile cutting machine engineered for PVC, UPVC, and vinyl window and door production. Equipped with two synchronized carbide-tipped saw blades (Ø400mm), it performs simultaneous two-end cutting at 45° and 90°, delivering burr-free, melt-free ends with repeat accuracy up to ±0.3mm. The machine features pneumatic auto-feed with adjustable damping, horizontal and vertical pneumatic clamping, and a movable head with digital length positioning (450–3500mm range). Designed for batch processing, it cuts window frames, sashes, mullions, and transoms in a single pass, significantly improving production efficiency. Built with a welded steel frame and precision linear guides, it offers low-vibration, long-service operation. CE certification and voltage customization (220V/380V/415V) are available for global markets.

Precision CNC Aluminum Spacer Bending Machine​ is a high-accuracy automatic equipment designed for bending aluminum spacer bars (6–27mm) into seamless frames for insulating glass units (IGU). Featuring servo-driven feeding, PLC control, and a user-friendly touch screen, it delivers ±0.1mm bending accuracy and supports continuous production of rectangles, triangles, and arches. Ideal for double glazing and IG glass manufacturers seeking efficiency and quality
