Équilibrage vs Tendeurs de fil pneumatiques
Lorsque la scie à fil diamanté sans fin est en marche, Il nécessite une certaine tension dans la zone de traitement pour passer d’un état flexible à un état rigide, générer une force de coupe pour produire des pièces de qualité.
Le maintien d’une ligne droite dans la zone d’usinage permet d’obtenir une bonne qualité de coupe, surfaces lisses, et une fine rugosité. toutefois, si la scie à fil diamanté sans fin dans la zone d’usinage se plie, La qualité de coupe se détériore, conduisant à des marques linéaires proéminentes sur la surface et à une mauvaise rugosité.
Pendant le traitement, factors such as heat generated by high-speed endless diamond wire saw operation, tension, excessive feed speed, and mismatched cutting forces can cause the wire to elongate. If the machine’s operating path does not adjust accordingly, issues like wire loosening and vibration may occur, affecting cutting effectiveness.
To keep the endless diamond wire saw in the processing area close to a straight line, a wire tensioning device is installed on the machine’s operating path. This device provides a certain tension and automatically adjusts it when needed, ensuring the endless diamond wire saw maintains a straight line and meets processing requirements.
Actuellement, there are two types of wire tensioning devices for endless diamond wire saw cutting machines: the counterweight wire tensioning device and the pneumatic wire tensioning device. What sets them apart?
The counterweight wire tensioning device utilizes heavy iron blocks (or other materials) to control tension based on the fixed weight. It provides a consistent tension level, which cannot be adjusted or controlled, regardless of the endless diamond wire saw’s diameter variations.
D’un autre côté, the pneumatic wire tensioning device requires an air compressor and offers flexibility in tension control through a tension adjustment valve. It allows for the adjustment of tension levels according to different endless diamond wire saw diameters, ensuring prolonged endless diamond wire saw lifespan.
This is my personal understanding of the counterweight and pneumatic wire tensioning devices for endless diamond wire saw cutting machines. I have had the opportunity to experience both devices and would like to provide a brief introduction here. If there are differing interpretations, please feel free to reach out to us.
