550 CNC External Pivot Precision Miter Saw, 45°/90

Product Overview

This 550 CNC outward swing precision cutting saw is engineered 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 from the machine body, providing operators with a clear line of sight, safer blade access, and effortless material loading — especially for long or bulky profiles.

Equipped with a high-performance Ø550 mm carbide circular saw blade, CNC servo control, and a robust pneumatic clamping system, this machine delivers clean, burr-free cuts with exceptional repeatability. Whether you're fabricating window frames, door profiles, or industrial aluminum extrusions, the outward swing design minimizes operator fatigue while maximizing cutting precision.

Available in single-head and double-head configurations to match your production scale.

Key Features

Swing-Out Head Design — Cutting heads pivot outward, creating a completely open work area for effortless loading and positioning of long profiles. No awkward maneuvering, no material clearance issues.

Dual-Angle CNC Positioning — Switch between 45° and 90° with a single command. Digital angle control eliminates manual adjustment and ensures every cut hits tolerance.

550mm High-Performance Blade System — Large-diameter blades handle wide and thick profiles — thermal break aluminum, multi-chamber UPVC, heavy curtain wall extrusions — with smooth, burr-free edges.

Pneumatic Clamping System — Fast-acting clamps secure profiles instantly at cycle start. No hand-tightening, no mid-cut slippage. Operator loads, presses start, the machine does the rest.

Heavy-Duty Frame Construction — Rigid welded steel frame absorbs vibration and maintains alignment under continuous production loads. Built for multi-shift operation.

Dust Extraction Ready — Integrated collection ports connect to shop dust systems. Cleaner work area, better visibility, healthier operators.

User-Friendly CNC Interface — Intuitive digital control panel with preset cutting programs. Most operators are productive within a single day of training.
