3+2 Axis CNC End Miller for Special-Shaped Aluminum Mullions | Window & Curtain Wall Machinery

One-Setup, Multi-Angle Machining

Eliminates repeated clamping and manual repositioning. The tilting spindle handles 0°–90° (or wider) angles in a single cycle, making complex mullion geometries simple and repeatable.

✅ Seamless Assembly, Zero Gaps

±0.1mm precision ensures perfect mullion-to-frame mating—critical for high-end system windows and curtain walls where aesthetics, airtightness, and structural performance matter.

✅ Drastically Reduced Labor & Scrap

Automatic tool calibration and intelligent program storage minimize operator skill dependency, human error, and material waste.

✅ Maximum Production Flexibility

Handles standard, reinforced, arched, and special-section mullions with equal ease—ideal for both bespoke architectural projects and high-volume series production.

✅ Industrial-Grade Reliability

Heavy-duty frame, precision ball screws, and servo-driven axes ensure long-term dimensional stability and consistent machining quality.

Multi-Angle 3+2 End Miller -- The Ultimate Solution for Special Shape Aluminum Mullion Processing.

How It Works）

Load & Secure – Place mullion profiles on the worktable and clamp using pneumatic or servo clamping systems.

Select Profile Program – Choose the correct machining program via the CNC touchscreen interface.

Auto Tool Calibration – The machine automatically sets tool zero and cutting depth for absolute accuracy.

3+2 Axis Machining – The spindle tilts and moves along X/Y/Z axes to perform end milling, step cutting, and chamfering in one continuous cycle.

Unload Finished Parts – Remove perfectly machined mullions, ready for immediate assembly.

FAQ

Q: Is this a full 5-axis machining center?

A: No. It is a 3+2 axis machine: 3 CNC linear axes plus spindle tilt positioning. It is purpose-built for aluminum mullion end milling—more efficient and cost-effective than a full 5-axis center for this specific application.

Q: Can it handle my special mullion design?

A: Yes. Send us your profile cross-section and end-face drawing. We will verify angles, tenon depth, and step dimensions, then recommend the optimal configuration.

Q: How many profiles can be machined at once?

A: Depending on table width and clamping fixtures, multiple mullions can be processed per cycle—significantly improving productivity.

Q: What software does it use?

A: Standard CNC/PLC HMI. Optional integration with ERP/MES or window-profile software is available.

Q: What is the delivery time?

A: Standard models: 10–30 days. Customized models: 25–45 days.
