What are the reasons for the tooth loss of diamond saw blades?

2021-01-13 18:33:13

Diamond saw blades, as a high-performance multi-blade tool, are widely used for the sawing of various brittle and hard materials.(Chian Stone Blade Segment Multi-Blades Saw Manufacturer

In the actual sawing process, the problem of tooth loss often occurs. The reason: in addition to common misoperations that cause the saw blade to wear out in advance, the quality of the saw blade itself is also the key. As long as the diamond saw blade with excellent quality, its life and fatigue resistance are often very outstanding, but the relative cost is also very high.

Regardless of the factors in the use link, from the manufacturing link, the welding temperature is the key to affecting the tooth loss. In the entire production process of diamond saw blades, there are two most common ways of tooth welding: high frequency brazing and laser welding.

From the perspective of welding quality, laser welding is undoubtedly the best. The welding temperature can be perfectly controlled within a reasonable range, and the saw tooth and the base can be perfectly combined, and the fatigue resistance of the saw tooth is improved. However, due to the high cost of laser welding equipment, the current mainstream welding method adopted by domestic saw blade manufacturers is high-frequency brazing.

The diamond saw blade is durable and the temperature control of the welding teeth is the key

Although high-frequency brazing has also achieved automatic welding(Wholesales Diamond Blade Brazing Machine), the actual welding process still requires manual assistance. The temperature of the welding teeth requires manual attention at all times. Because in the welding process, once the temperature of the welding tooth is higher than 950 degrees Celsius, a large amount of martensite structure will appear around the saw tooth. In this way, the welding effect of the sawtooth will be greatly reduced.

In addition to controlling the temperature during welding, the tempering of sawtooth is also an important link. After the saw tooth is tempered, a large amount of tempered martensite structure will be formed on its surface. This structure changes the fragile characteristics of the martensite structure and can effectively enhance the wear resistance and fatigue resistance of the saw tooth itself.

How to prevent the problem of diamond saw blade tooth loss?

Choosing a diamond saw blade should focus on the production process of the saw blade manufacturer. It is a must-do homework to understand the technical strength of the saw blade manufacturer in many ways. Of course, this can only ensure the quality of diamond saw blades in terms of source quality. In the process of actual use of diamond saw blades, it is a must to train operators to operate norms and equip the sawing equipment with necessary lubrication devices. The installation of a micro-lubrication device on the sawing equipment of the diamond saw blade can effectively solve the problem of heat dissipation of the saw blade during operation. The micro-lubrication device continuously sprays atomized lubricating oil to the saw blade at a rate of 0.05 milliliters per second to reduce the thermal wear of the saw blade.

Preventing diamond saw blades from losing teeth is actually a systematic project. Quality control at the production stage is far from enough. From the saw blade manufacturer responsible for the production to the user. Any error in any of the links in the middle will cause the necessary strain on the saw blade. To completely solve the problem of diamond saw blade tooth loss, it is more necessary for the cooperation between industries to tide over the difficulties.
