Reason one: the cutting force of the saw tooth exceeds its limit

As a multi-blade tool, the diamond saw blade has its own cutting performance determined by the serration, although the saw blade of the diamond saw blade is made of diamond. However, no matter how excellent the non-metallic properties of diamond, there is still fatigue life.

When using a diamond saw blade to cut different materials, the life of the diamond saw blade is often affected by the material of the saw cut profile, the speed at which the saw blade feeds, and the rotational speed.

When we use a diamond saw blade for sawing, if the saw blade has a cutting force per unit area that exceeds its own fatigue life peak, then the sawtooth root fracture often occurs.

Reason 2: The serrated cooling and cooling work is not done well.

Since the saw blade is working, it often requires a large amount of sawing, which makes the sawtooth often need to withstand extremely high temperatures. For the diamond saw blade, although the material of the sawtooth is excellent, the ruthless hands can't stand the time.

Among them, when the diamond saw blade is cut for a long time, there are often many scratches at the joint between the sawtooth and the substrate. After the occurrence of scratches on these substrates, if not treated in time, the aluminum chips will stick to the substrate.

Over time, the aluminum scraps stuck to the substrate tend to cause the saw blade to dissipate heat, causing the temperature of the sawtooth to rise continuously. When the time is up, the sawtooth will be deformed by heat, which will cause the saw blade to be sawed. At the time of cutting, the root of the saw tooth broke.

In this regard, whether in the speed of the saw blade or the speed of the saw blade feeding, if we want to control the cutting force of the saw tooth in a reasonable interval, we must flexibly adjust the various sawing materials according to the sawing material. Parameters to prevent breaks in the saw teeth.

Reason three: material factors for sawing

Different materials have different characteristics. The harder the material, the mechanical impact of the saw blade is different when sawing with a diamond saw blade.

For stone materials, diamond saw blades tend to wear faster, while for aluminum profiles, the mechanical impact of diamond saw blades is often lighter.

Therefore, for those diamond saw blades used for sawing aluminum, the lifespan tends to be longer and the sawtooth roots are relatively less broken.

Starting from the cause of the fracture at the root of the saw blade of the diamond saw blade, in order to effectively prevent the root from breaking in the sawtooth, we can take targeted measures to prevent it.

Measure 1: Do the cooling work during the sawing process of the diamond saw blade

When the sawtooth is in contact with the material, the heat generated by the friction is huge. Although the high-temperature resistance of the diamond saw blade itself is prominent, the saw blade will wear out for a long time.

In this regard, we need to do the cooling and cooling of the sawtooth during the sawing process. Among them, in order to effectively ensure that the temperature of the sawtooth is within a reasonable interval, a cooling device called a micro-lubrication device is currently widely used to cool the diamond sawtooth.

Since the micro-lubrication device can spray the cutting fluid into the saw blade in a volume of 0.05 ml in the form of atomization in one second, the surface of the saw blade is sawed. The temperature will be controlled within a reasonable range.

Measure 2: Saw blade grinding, revitalizing the diamond saw blade

The diamond saw blade is still a consumable in nature, even though we have added a small amount of lubrication to the saw blade, but this can only delay the wear of the saw blade.

For those diamond saw blades that have broken or worn at the root of the sawtooth, it is often not enough to rely on the measure one. In this regard, the use of grinding method can effectively improve the cost performance of a single diamond saw blade.

The damaged diamond saw blade recovers nearly 80% of the cutting performance, and for the enterprise, it is also in the purchase of the saw blade for the company.
