What Is Friction Sawing Machinery?
Friction sawing machinery is machinery using a cutting wheel to quickly cut long, thin metal materials such as steel pipes and wire ropes.
Compared to disc grinders, which are similar products, friction sawing machinery has two main features: first, the cutting wheel is larger and the motor output is higher than that of a disk grinder. As a result, the cutting time is faster; second, while disk grinders are hand-held, high-speed cut-off machines are used on a tabletop and can cut a targeted area with high precision.
However, friction sawing machinery is a cutting-only machine and cannot be equipped with an abrasive wheel, as is the case with a disk grinder.
Uses of Friction Sawing Machinery
Friction sawing machinery can cut metal stably because the cutting wheel and the material to be cut are held in place by the arm and vise. Therefore, they are suitable for cutting thin or long materials.
Thus, friction sawing machinery can cut large quantities of metal materials in a short time and is utilized for cutting out agricultural materials and monopipe pipes. Furthermore, angle cutting is possible up to 45 degrees by adjusting the inclination of the vise. Therefore, it is also useful when making frames that combine angle materials.
Principle of Friction Sawing Machinery
When selecting a model, it is necessary to check the size of the cutting wheel, vise opening, rotation speed, and power consumption according to the application.
First, the size of the cutting wheel differs depending on the thickness of the material that can be cut. Currently, the most common cutting wheels are 305mm, 355mm, and 405mm. The 305mm can be cut up to a thickness of 90mm, making it suitable for cutting several pieces at once. On the other hand, the 355mm wheel can cut up to 120mm thick and is suitable for cutting round pipes one by one. The 405mm cut-off wheel is for professional use, and larger-size cut-off wheels are also available.
Next, select a vise opening that matches the size of the material to be cut.
The rotation speed is related to the beauty of the cut surface.
Lastly, power consumption is a factor to consider.
In addition, it is necessary to confirm the angle at which angled cutting is possible on the left and right sides of the machine, as it may differ depending on the model.
