Application of Double-head Cutting Saw for Aluminum Profiles in Door and Window Processing

The double-head cutting saw for aluminum profiles is a core piece of equipment in the door and window processing field. It is mainly used for high-precision fixed-length and fixed-angle cutting of aluminum alloy door and window profiles, directly determining the splicing accuracy, sealing performance and appearance quality of finished doors and windows, and thus has an irreplaceable application value in door and window production.

Its specific application scenarios and functions are as follows:

1. Angle cutting of door and window frame and sash profilesThe splicing of aluminum alloy door and window frames and sashes usually requires 45° angle butt joint (such as the frame splicing of casement windows and sliding doors). The two saw blades of the double-head cutting saw can synchronously adjust the angle (mainly 45°/90°). One-time feeding can complete the symmetrical cutting of both ends of the profile, ensuring consistent angles at both ends, greatly improving the fit degree of gaps after splicing, and avoiding problems such as "angle misalignment" and "excessively large gaps".For profiles requiring 90° right-angle splicing (such as the mullions of some sliding windows), the equipment can also quickly switch to the angle mode to meet the cutting needs of different structures.

2. High-precision fixed-length cutting to ensure the dimensional uniformity of doors and windowsThe double-head cutting saw is equipped with a CNC positioning system or a precision scale, which can accurately control the cutting length of profiles with an error range of 0.1~0.3mm.In the mass production of doors and windows of the same specification, it can ensure that the length and angle of each profile are completely consistent, avoiding assembly difficulties caused by dimensional deviations, while ensuring the dimensional accuracy of finished doors and windows to meet installation standards.

3. Efficient cutting of complex profilesThe cross-section of door and window profiles often has complex structures such as grooves and reinforcing ribs (e.g., the cavity structure of thermal insulation broken bridge aluminum profiles). The saw blades of the double-head cutting saw are made of cemented carbide, featuring strong stability during cutting, without profile deformation or edge chipping, and can ensure the flatness of the profile cross-section, laying a good foundation for the subsequent installation of hardware and sealing strips.

4. Improving the production efficiency of doors and windowsCompared with single-head cutting saws that require two clamping operations to cut both ends of a profile, the double-head cutting saw can complete the processing of both ends with one-time clamping, greatly shortening the cutting time of a single profile. Meanwhile, the equipment can be adapted to an automatic feeding system to realize semi-automatic or fully automatic production, which is especially suitable for the mass production needs of door and window processing plants and significantly improves the overall production capacity.

5. Adapting to the processing needs of different types of doors and windowsWhether it is broken bridge aluminum insulated doors and windows, ordinary aluminum alloy doors and windows, or frame profiles of sunrooms, the double-head cutting saw can meet the cutting requirements of profiles with different thicknesses and hardness by adjusting the saw blade speed, cutting pressure and angle, making it a universal core equipment for door and window processing.
