How To Eliminate The Tensioning Of Brazed Diamond Saw Blades

The tension of the diamond saw blade, also known as the stress, is the external force received by any point on the base of the diamond saw blade, and the influence of these forces on the entire saw blade. The force on diamond is divided into tensile stress, shrinkage stress, bending stress, etc. When these stresses exceed a certain critical value, the entire saw blade will bend and break.

So how is the tension of the diamond saw blade formed? The main points of formation are as follows:

1. Metallurgical factors: the memory of the influence of the steel itself on the process of forming, machining, cutting and heat treatment because of the material characteristics. Simply put, because the substrate maintains some memory during processing, such as tensile memory, bending memory, etc.

Local heating: local internal tension caused by uneven expansion and local volume change due to sunlight, welding, etc.

In the process of saw blade leveling, there is mechanical or percussion, hammer equal operation.

After the saw blade is produced and leaves the factory, the saw blade has a collision, bump, etc., resulting in local deformation or tension memory.

The brazed diamond saw blade is mainly affected by the first two factors, resulting in some tension on the saw blade. If these tension cannot be eliminated, it is found that the life of the saw blade will be greatly shortened during the cutting process. There are also obvious situations in which the sharpness is not high and the deformation is easy, so tension relief is a process that the saw blade must go through. So how to eliminate the tension of the vacuum brazed diamond saw blade?

1: It can be solved by placing the saw blade naturally for a period of time to eliminate the tension of the saw blade: natural tension elimination is to place the saw blade for a certain period of time, half a month to a few months, and brazing the diamond saw blade through continuous links tension memory. In general, most of the residual tensions in this type of saw blade can be resolved in this way.

2: Heat treatment: Simply put, the residual tension of the saw blade is eliminated by annealing or tempering. Simply put, after the saw blade is heated to 400-700 degrees Celsius, the saw blade is tempered, which can quickly eliminate the tension of the saw blade. High frequency welding saw blades can also be treated in this way.

3: Vibration treatment: In simple terms, this method is an additional tension imposed on the saw blade through resonance. In terms of specific performance, the entire saw blade will undergo microscopic deformation in resonance, thereby reducing brazing. Residual tension of diamond saw blades.

4: Static treatment: Give the saw blade a strong driving force, but keep the saw blade in a static state. In short, continue to increase the static force, and finally reach the yield limit value that the saw blade can withstand. The object gets stuck on the saw blade teeth, and the torque is continuously increased, and finally reaches a critical value. After a period of time, the tension of the brazed diamond saw blade can be eliminated. However, this method is affected by the detection instrument and is not commonly used.
