800mm CNC Curtain Wall End Milling Machine

Shandong Lebulang Precision Machinery Co., Ltd., operating under the Lebulang Machine brand, has been manufacturing aluminum processing equipment at its Jinan, China factory since 1996. This 3-axis servo CNC end miller processes aluminum curtain wall and facade profiles, door and window frames, and architectural extrusions. It features an 800 mm X-axis travel, automatic spindle rotation from 0° to 90°, a heavy-duty cast iron base, and multi-profile clamping for batch production. A SYNTEC industrial CNC system with a user-friendly HMI supports USB CAD import and pre-loaded profile libraries for quick setup.

• 800mm X-axis travel: The 800mm CNC Curtain Wall End Milling Machine provides 800 mm of working length along the X axis, accommodating large curtain wall and facade profiles in a single setup.
• 3-axis CNC servo control: X, Y, and Z axes are driven by servo motors coupled to precision ball screws. Positioning accuracy is specified at ±0.02 mm, supporting consistent tenon and groove dimensions across production batches.
• Heavy-duty cast iron base: The machine bed is cast iron, designed to damp vibration and maintain stability during high-speed milling. This contributes to smooth, burr-free end faces and longer tool life.
• Automatic 0° to 90° spindle rotation: The milling spindle can rotate from 0° (horizontal) to 90° (vertical) under program control. Horizontal and vertical profile ends can be machined in one clamping without manual repositioning of the workpiece or tooling.
• Multi-profile clamping: The clamping fixture can secure 3 to 5 profiles simultaneously, allowing batch processing of identical end-milling operations in a single cycle.
• SYNTEC industrial CNC system: The control unit includes a color HMI, USB port for CAD file import, and pre-loaded profile libraries with common tenon and notch geometries. Operators select the program, load the profiles, and start the cycle without writing G-code.

800mm CNC Curtain Wall End Milling Machine

How It Works

The 800mm CNC Curtain Wall End Milling Machine operates with the operator loading up to five aluminum profiles into the pneumatic clamping fixture. After selecting the machining program from the SYNTEC controller — either from the pre-loaded library or a CAD-imported file — the cycle starts. The servo-driven X, Y, and Z axes position the milling cutter at the first profile end. The spindle can rotate automatically between 0° and 90° to machine both horizontal and vertical surfaces without unclamping the workpieces. A Φ350 mm carbide milling cutter running at 2800 rpm removes material to form tenons, notches, and grooves. The maximum tenon depth is 100 mm, and the maximum profile cross-section is 330 mm wide by 180 mm high. After completing the programmed sequence on one end, the axes reposition to the next workpiece. Once all profiles in the batch are finished, the clamps release and the operator removes the machined parts.

Key Components

• Cast iron machine bed: Provides a rigid, vibration-damping foundation for the linear guide rails and moving axes. The mass of the casting helps maintain cutting stability during heavy milling passes.
• Servo motors and ball screws (X/Y/Z): AC servo drives with precision-ground ball screws deliver the ±0.02 mm positioning accuracy across the 800 mm X-axis travel, 330 mm width capacity, and 180 mm height capacity.
• Rotating spindle assembly: A 3 kW motor drives the Φ350 mm milling cutter at 2800 rpm. The spindle housing rotates from 0° to 90° under servo control for automatic switching between horizontal and vertical end milling.
• SYNTEC CNC controller: Industrial-grade CNC system with a color touchscreen HMI. Stores profile libraries, imports CAD drawings via USB, and manages axis motion, spindle rotation, and clamping sequences.
• Pneumatic multi-profile clamp: Holds 3 to 5 profiles simultaneously. Clamping force is regulated by the air pressure supply set between 0.5 and 0.8 MPa. Jaw inserts can be changed for different profile cross-sections.
• Safety enclosure: Guards cover the milling zone during operation. An emergency stop circuit halts all axes and spindle rotation when activated.

FAQ

Q1: What profiles can this machine process?

A: It is designed for aluminum curtain wall profiles, facade extrusions, and door and window frame sections. The maximum processing cross-section is 330 mm wide by 180 mm high, with a tenon depth up to 100 mm.

Q2: How does the automatic spindle rotation work?

A: The spindle rotates from 0° (horizontal) to 90° (vertical) under servo control. This allows the machine to mill both horizontal and vertical profile ends in one clamping without the operator needing to reposition the workpiece or change tooling manually.

Q3: How many profiles can be machined at once?

A: The pneumatic clamping fixture can hold 3 to 5 profiles simultaneously, depending on profile cross-section. All clamped profiles are machined in the same cycle.

Q4: Is programming difficult?

A: The SYNTEC controller includes pre-loaded profile libraries with common tenon and notch geometries. CAD files can also be imported via USB. Operators select the program from the touchscreen and start the cycle. An English manual and operation video are provided.

Q5: Can the power supply be customized for different countries?

A: Yes. The standard configuration uses 380V/50Hz three-phase power. Other voltages and frequencies can be specified at the time of order to match local electrical standards.
