The application of aluminum profile CNC screw drilling machine in doors and windows

The CNC screw-drilling and milling machine for aluminum profiles is a key equipment in achieving high-precision and large-scale assembly in the production of aluminum doors and windows. Its application runs through the processing stages of core components such as door and window frames, sashes, and middle beams. The specific application scenarios and value can be classified into the following categories:

1. Core processing of corner connections for doors and windows

This is the most core application scenario of this equipment. The corner connections between the frames and sashes, as well as between frames, require a mechanical connection structure of screws + angle brackets to ensure strength.

The CNC screw-drilling and milling machine can precisely process the screw holes and angle bracket positioning grooves at the ends of the profiles according to the cross-sectional dimensions of the profiles and the specifications of the angle brackets. The precise control of the CNC system can ensure that the depth, spacing, and verticality errors of the holes and slots are extremely small, allowing the screws to firmly embed in the connection parts of the angle brackets and profiles, completely solving the problems of traditional angle bracket connections being prone to loosening and corner cracking.

Whether it is a flat door and window, sliding door and window, or heavy-duty insulated aluminum doors and windows, they all need to be processed with corner connection holes through this equipment, especially suitable for high-end door and window products with high requirements for sealing and wind pressure resistance.

2. Connection processing of middle beams and frames

The middle beam is a key component for separating the glass of doors and windows, and the connection accuracy between the middle beam and the main frame directly affects the overall flatness and sealing performance of the doors and windows.

The CNC screw-drilling and milling machine can process the screw holes and对接 slots at both ends of the middle beam and the corresponding positions of the main frame， achieving a rigid connection between the middle beam and the main frame. Compared with traditional screw fixation or welding methods， this screw connection is more stable and does not damage the insulation and heat insulation structure of the profiles， ensuring the insulation performance of the doors and windows.

The equipment supports the storage of parameters for multiple middle beam specifications， allowing for quick switching of processing programs and adapting to different grouting designs of door and window orders.

3. Milling processing for installation benchmarks of hardware components

The installation accuracy of door and window hardware components (such as hinges， handles， and actuators) determines the smoothness and sealing performance of the doors and windows.

In addition to drilling holes， the CNC screw-drilling and milling machine can also perform milling processing on the surface of the profiles， such as milling out the installation grooves and positioning reference surfaces for the hardware components， ensuring that the hardware components can be accurately embedded and firmly fixed， avoiding problems such as door jamming and leakage caused by installation deviations.

For heavy-duty doors and windows with multiple hardware components， the high-precision milling capability of the equipment can ensure the consistency of multiple hardware installation positions， improving the durability of the doors and windows.

4. Adaptation for large-scale and standardized production

In the batch production of door and window manufacturers， the automation characteristics of this equipment demonstrate significant advantages：

Multi-specification compatibility： It can store hundreds of processing parameters for different profiles， and for different series and models of door and window orders， only the corresponding program needs to be retrieved to switch the processing， without the need for repeated manual debugging， significantly reducing the changeover time.

Semi-automatic / fully automatic process： Combined with automatic feeding and discharging devices， it can achieve continuous processing of profiles， and the processing time for the holes and slots of a single profile can be shortened to 30-60 seconds， meeting the delivery requirements of large-scale orders from door and window manufacturers.

Quality stability and controllability： CNC processing replaces the randomness of manual drilling and milling， ensuring consistent processing accuracy of the same batch of door and window products， reducing the rework rate caused by human operational errors.

5. Customized processing for special door products

For special door products (such as arc windows， corner windows)， system doors and windows， etc.， the flexibility advantage of the CNC screw-drilling and milling machine is obvious：

It can precisely process the holes and slots at the ends of non-standard profiles by importing CAD drawings， meeting the connection requirements of non-standard doors and windows.

System doors and windows have extremely high requirements for profile processing accuracy， and the micro-mill error control capability of the CNC equipment can match the strict assembly standards of system doors and windows， ensuring the core performance of the products such as sound insulation， heat insulation， and wind pressure resistance.
