In the aluminum door and window manufacturing industry, hinges, as the core components connecting door/window frames and sashes, have their machining accuracy directly determining the smoothness of opening/closing, sealing performance, and service life of doors and windows. Meanwhile, aluminum door and window hinge manufacturing machines, with their integrated processing capability that combines aluminum hinge drilling, cutting, and counterboring in one, are becoming key equipment for modern door and window production enterprises to improve efficiency and ensure quality. They have completely overcome the limitations of traditional manual processing or single-process machining.
Precise Drilling: Ensuring Hinge Assembly Accuracy
The hole position accuracy of hinges directly affects the fit of subsequent door and window assembly. Equipped with high-precision servo motors and a CNC system, the equipment can automatically adjust drilling position and depth based on hole parameters of hinges of different specifications (such as hinge-type, sliding stay-type, etc.), controlling the hole diameter error within ±0.05mm. Whether it is round mounting holes or special-shaped positioning holes, they can be accurately completed through preset programs, avoiding problems such as hole deviation and inconsistent hole diameters caused by manual drilling, and ensuring the perfect fit between hinges and door/window frames and sashes.
Efficient Cutting: Achieving Fixed-Length Processing of Hinge Profiles
Aluminum hinges are mostly cut from aluminum alloy profiles. Traditional cutting equipment is prone to profile deformation and uneven cutting surfaces, which affect the structural strength of hinges. The aluminum door and window hinge manufacturing machine is equipped with high-speed alloy saw blades and an automatic feeding mechanism. It can realize fixed-length cutting of profiles according to hinge length requirements, resulting in smooth and burr-free cutting surfaces with a perpendicularity error ≤0.1mm. Meanwhile, the equipment has automatic feeding and waste collection functions, increasing the cutting efficiency of a single profile by more than 30% compared with traditional equipment and effectively reducing material waste.

Precision Counterboring: Enhancing Hinge Installation Aesthetics and Stability
The counterboring process provides a hidden space for the heads of hinge screws, avoiding protrusions that affect door and window appearance and opening/closing feel. The counterboring mechanism of the equipment adopts adjustable tools, which can precisely control the counterbore depth and diameter according to screw specifications, ensuring that the screw heads are completely embedded in the hinge surface. This not only improves the overall aesthetics of doors and windows but also prevents screws from being damaged by external collisions, extending the service life of hinges.
