Metal cold sawing is a metal sawing technology performed at room temperature, usually using a circular saw blade for quick cuts.

Here are some details about metal cold sawing:

1.Sawing process: In the process of metal sawing, the heat generated when the saw teeth of the saw blade cut the work piece into two parts is mainly taken away through the sawdust, so that the sawed work piece and the saw blade itself remain relatively small. low temperature.

2.Type: Metal cold sawing is mainly divided into two types, one is high-speed steel cold cutting saw blade, and the other is TCT toothed alloy saw blade. These saw blades are suitable for different types of materials and sawing requirements.

3.Advantages: The significant advantages of metal cold sawing include the flat end face of the cut, high smoothness, and the avoidance of changes in material structure and the generation of internal stress caused by high temperatures. In addition, since the pressure of the saw blade on the material is small, it will not cause deformation of the material being cut.

4. Application material: The material used in metal cold sawing is usually a special alloy cutter head, such as cermet. Saw blades made of these materials are suitable for cutting ferrous metals such as iron and steel, and usually work at a lower speed, about 100-120 rpm.

5. Applicable materials: Metal cold saws can be used to cut profiles, bars, etc. with various wall thicknesses, such as stainless steel, cold rolled iron, solid iron, car door and window clips (including stainless steel), high carbon steel, low carbon steel, bearings Steel, medium carbon steel, etc.

6. Comparative difference: Compared with hot sawing, cold sawing can better maintain the structural integrity of the material and reduce dimensional changes caused by increased temperature. Therefore, cold sawing is often chosen as the processing method for materials that require high precision and high quality cuts.

7. Problems and their solutions: Although metal cold sawing has many advantages, some problems may be encountered during actual application, such as saw blade wear, cutting accuracy control, etc. These problems usually need to be solved by optimizing sawing parameters and selecting appropriate saw blade materials and tooth shapes.

To sum up, metal cold sawing is an efficient cutting method that maintains material quality and is very suitable for demanding metal processing fields. Understanding different materials and sawing requirements can help select the most appropriate cold saw equipment and saw blades to achieve the best cutting results.
