Precision Thermal Break Aluminum Window Machinery For Energy-Efficient Window Manufacturing

The 550 CNC Internal Swivel Precision Saw is engineered for high-accuracy 45° and 90° cutting of aluminum, UPVC, and curtain wall profiles. Featuring an inward-tilting (inner swing) dual-head design with 550mm blades, it delivers clean, burr-free cuts with minimal material waste. Ideal for aluminum window, door, and façade manufacturing where precision and repeatability are critical.

This 550 CNC outward swing precision cutting saw is designed for high-accuracy 45° mitre and 90° square cutting of aluminum profiles, thermal break aluminum windows, and UPVC/PVC profiles. The saw head swings outward for safe, easy operation and material loading. Equipped with a Ø550 mm carbide blade, CNC control, and pneumatic clamping, it delivers clean, burr-free cuts with excellent repeatability. Available in single-head and double-head configurations.

This CNC fixed-length cutting saw is purpose-built for high-precision glazing bead (glass bead) processing in thermal break aluminum and UPVC window & door fabrication. Equipped with a servo-driven length stop system, it delivers accurate 90° cut-to-length results with ±0.1 mm repeatability. The pneumatic clamping, high-speed carbide blade, and user-friendly CNC touchscreen ensure clean, burr-free cuts and fast cycle times. Compact in design yet robust in performance, it is ideal for high-volume glazing strip production. CE certified, 12-month warranty, global technical support

This 550 CNC precision cutting saw is designed for high-accuracy fixed-length cutting of aluminum profiles, UPVC, and light metal sections. Equipped with a CNC servo-driven length stop system and a 550 mm carbide circular saw blade, it delivers repeatable precision at both 45° mitre and 90° square angles. The heavy-duty steel frame, pneumatic clamping, and user-friendly CNC touchscreen interface ensure stable performance, clean cuts, and easy operation. Widely used in aluminum window & door manufacturing, curtain wall fabrication, and industrial profile processing. CE certified, with 12-month warranty and global technical support

The 450mm CNC Double Head Internal Swing Precision Cutting Saw (45°/90°) is a high-end profile cutting machine designed for aluminum, thermal-break aluminum, and UPVC/PVC window and door production. Equipped with two synchronized Ø450mm TCT carbide blades and CNC-controlled inward-swing saw heads, it performs simultaneous two-end mitre cutting at 45° and 90° with repeat accuracy up to ±0.1mm. The machine features pneumatic auto-feed with adjustable damping, horizontal and vertical pneumatic clamping, and CNC digital positioning for cutting lengths up to 3700mm. The internal swing head design saves floor space while ensuring stable, vibration-free operation. Built for batch production, it delivers burr-free, square ends ready for assembly. CE certification and voltage customization (220V/380V/415V) available for global markets.
