HJN-70A V Notch Saw

This machine is a special equipment used for cutting 90° V-shaped grooves in aluminum-plastic door and window profiles. It is suitable for profiles with a thickness of no more than 120 mm and can complete cutting in a single pass, making it an essential device for aluminum-plastic door and window processing operations.
Its main electrical and pneumatic components adopt imported and high-quality domestic products. The design is based on the specifications of domestic plastic profiles and the structural forms of doors and windows to meet application requirements.
This machine features a horizontal structure with linear horizontal movement and double saw blade cutting. It is mainly used for cutting V-shaped notches and can also perform 45° cutting, with adjustments made according to the set data for profiles and doors/windows.
The profile clamping and cutting feed of this machine are controlled by a combination of pneumatics and electricity. The feed speed is adjustable at will, ensuring convenient operation, stable running and high safety performance.
The saw blades are carbide-tipped circular saw blades with high wear resistance, suitable for high-speed cutting of aluminum-plastic profiles. The machine boasts advanced structure, reliable performance, easy and flexible operation, stable and safe running, high processing accuracy and long service life, making it one of the most ideal processing equipment for plastic-steel doors and windows in China at present.
The bed is welded from high-quality steel plates after bending and forming, with internal stiffening plates. It undergoes aging treatment after welding, ensuring sufficient rigidity and stability of the bed.

Applications:

This machine is specially designed for cutting 90° V-shaped grooves on aluminum‑plastic and plastic‑steel door and window profiles, and can also perform 45° cutting. It is suitable for profiles with thickness ≤120 mm and achieves one‑pass forming. It is widely used in plastic‑steel door and window factories, aluminum‑plastic profile processing workshops and building materials processing enterprises. It meets the requirements of V‑notch and angle cutting for various standard door and window structures, supports batch and customized processing, and provides stable and accurate groove processing for the production of high‑quality plastic‑steel doors and windows.
