CNC Heavy Duty Curtain Wall Notting Saw

Overview

The Heavy Duty Curtain Wall Notching Saw is a professional-grade cutting solution engineered specifically for aluminum curtain wall and facade profile fabrication. Built with a rigid steel frame and advanced CNC servo control, it delivers repeatable precision, multi-angle flexibility, and industrial-grade durability for high-volume production environments.

Whether you're processing commercial curtain walls, storefront systems, or architectural aluminum extrusions, this machine ensures clean, burr-free notches with minimal material waste — reducing manual rework and boosting overall throughput.

Key Features

1. CNC Precision Control

Equipped with a high-response servo drive system and CNC programmable controller, the cutting head positioning accuracy reaches ±0.1mm. Operators can store multiple notch programs for quick recipe switching between different profile types.

2. Heavy-Duty Rigid Structure

The machine body is constructed from thick-walled steel tubing with stress-relief treatment, eliminating vibration during high-speed cutting. This ensures consistent cut quality even under continuous 24/7 operation.

3. Pneumatic Clamping System

Dual-action pneumatic cylinders with adjustable pressure provide secure, mar-free clamping on delicate anodized or powder-coated aluminum surfaces. Quick-release function reduces cycle time between workpieces.

4. Multi-Angle Notching Capability

Supports 0°–90° (or specify your range) adjustable notch angles to accommodate various curtain wall mullion and transom configurations. Angle settings can be adjusted via digital readout or CNC interface.

5. High-Efficiency Chip Extraction

Integrated dust/chip collection port connects to standard industrial extraction systems, maintaining a clean work environment and extending blade life.

6. Operator-Friendly Interface

Intuitive touchscreen HMI with multi-language support (English, Spanish, Russian, Arabic). Visual programming allows operators to set notch dimensions without advanced technical training.

How It Works

1. The operator places the aluminum profile onto the worktable and activates the pneumatic clamps, which secure the workpiece from both vertical and horizontal directions.
2. The desired cutting angle is set using the magnetic scale digital display, and the dual saw blades are positioned accordingly within the ±45° range.
3. The hydro-pneumatic feed system advances the spinning blades into the profile at a controlled rate (0–3 m/min), cutting notches, grooves, or compound angles in a single pass.
4. The CNC system supports CAD graphic import and graphic programming, allowing operators to define notch patterns, hole positions, and slot dimensions directly from design files.
5. The three-axis full servo motor configuration (X, Y, Z axes driven by rack and pinion and ball screws) enables true three-axis linkage for drilling, milling grooves, round holes, special-shaped holes, key holes, and countersinks in one clamping.
6. An optional three-sided flip worktable allows the profile to be machined on three faces without repositioning, improving processing efficiency for complex aluminum extrusions.
7. After the cutting cycle completes, the blades retract, the clamps release, and the machined profile is removed.

FAQ

Q1: What is the maximum profile size this machine can process?

A: The standard model handles profiles up to 300×250 mm with a maximum cutting depth of 175 mm. Custom configurations for larger sections up to 350×300 mm are available on request.

Q2: Can it cut angles other than ±45°?

A: The standard model supports arbitrary angle cutting within ±45° on both sides. An optional CNC version extends the range to ±90° for more complex profile geometries.

Q3: What is the processing accuracy?

A: Positioning accuracy is specified at ±0.1 mm, with repeat positioning accuracy of ±0.05 mm under consistent operating conditions.

Q4: Do you provide after-sales service and training?

A: Free online operation training and remote technical support are provided. On-site training and installation can be arranged separately. A 12-month warranty applies, with lifetime technical support available.

Q5: Is the machine suitable for mass production?

A: The dual-blade synchronous cutting, pneumatic clamping, and controlled feed system are designed for continuous production in curtain wall fabrication facilities. Monthly production capacity from the factory is approximately 50 sets.
