High-speed electrospindle handles drilling, tapping, milling, and slotting in a single setup—reducing cycle times and improving overall efficiency.

✅ Automatic Tool Changing for Maximum Uptime

Integrated ATC system allows seamless transitions between tools, minimizing downtime and operator intervention.

✅ Precision That Builds Reputation

±0.1mm accuracy and rigid machine construction guarantee consistent, high-quality results—critical for premium window, door, and façade systems.

✅ Labor & Handling Savings

Servo-driven clamping and automated workflows reduce manual labor, material handling, and the risk of operator error.

✅ Versatile for Any Project

Handles standard, thermal-break, and complex architectural profiles with equal ease—ideal for both high-mix custom projects and high-volume production.

4000mm CNC Milling Machine for Industrial Aluminum Specifications

Key Components

• Servo motors and ball screws: AC servo motors on X, Y, and Z axes drive precision-ground ball screws. This provides the motion accuracy and repeatability needed for milling operations on aluminum profiles.
• Air-cooled spindle (3.5 kW): The high-speed spindle runs up to 18,000 rpm with an air-cooling system. Tool holders accept standard collets for a range of cutter shank diameters.
• Servo flip table (optional): A servo-driven rotary axis tilts the worktable to -90°, 0°, or +90°. This allows three-sided machining without repositioning the workpiece, useful for deep holes, side slots, and multi-face features.
• CNC controller: Industry-standard CNC system with a display for G-code programming and manual data input. Supports USB and network file transfer.
• Pneumatic clamps: Workpiece clamping is by pneumatically actuated fixtures positioned along the worktable. Clamp positions can be adjusted to suit different profile lengths and cross-sections.
• Machine frame and guide rails: Welded steel base with hardened linear guide rails. The structure is designed to maintain rigidity under cutting loads over the full 1500 mm X-axis travel.
