The service life of the brazed glass saw blade depends not only on the quality of the product itself, but also on the operating details during use. Incorrect operation may accelerate the wear of the saw blade, reduce cutting efficiency, and even cause safety problems. From preparation before cutting to operation during cutting, to maintenance after use, operating factors in multiple links will affect the service life of the saw blade.
Equipment debugging and parameter setting before cutting are the primary factors affecting the life of the saw blade. If the concentricity of the saw blade is not strictly calibrated during installation, the saw blade will vibrate eccentrically when rotating at high speed, which will cause the cutter head to bear uneven stress, accelerate the separation of the brazing layer from the substrate, and aggravate the wear of the cutter head. In addition, the speed setting of the cutting equipment is also crucial. If the speed is too high, the friction heat between the saw blade and the glass will increase sharply, and the excessively high temperature may destroy the metallurgical bonding strength of the brazing layer, causing the abrasive particles to fall off prematurely; if the speed is too low, the cutting performance of the saw blade cannot be fully utilized, causing the saw blade to bear greater resistance during the cutting process, which will also shorten the service life. Therefore, according to the specifications of the saw blade and the material of the glass, it is an important prerequisite to reasonably adjust the equipment speed to extend the life of the saw blade.
The feed speed control during the cutting process is directly related to the durability of the saw blade. Too fast a feed speed will cause the saw blade to bear pressure beyond the design load, causing the abrasive grains of the cutter head to wear out quickly or even break, and may also cause quality problems such as edge collapse and fragmentation of the glass. On the contrary, although a slow feed speed can ensure the cutting quality, it will increase the contact time between the saw blade and the glass, resulting in excessive frictional heat generation, which will also damage the saw blade. Only by selecting a suitable and stable feed speed according to the hardness, thickness and performance of the glass, and keeping the saw blade under uniform force during the cutting process, can its service life be effectively extended.
The use of cooling and lubrication measures has a significant impact on the brazed glass saw blade. During the cutting process, the friction between the saw blade and the glass will generate a lot of heat. If the heat cannot be dissipated in time, the excessively high temperature will reduce the hardness of the brazing layer, reduce its holding force on the abrasive grains, and cause the abrasive grains to fall off prematurely. Therefore, sufficient and appropriate cooling lubricant must be used. The cooling lubricant can not only take away the heat generated by cutting, but also form a lubricating film between the saw blade and the glass to reduce friction resistance. However, if the flow of the cooling lubricant is insufficient, the nozzle position is improper, or an unsuitable cooling lubricant is used, a good cooling and lubrication effect cannot be achieved, thereby accelerating the wear of the saw blade.
The standardization of the cutting operation is also an important factor affecting the life of the saw blade. During the cutting process, if the saw blade is subjected to excessive lateral force, such as forcibly changing the cutting direction, uneven force during cutting, etc., the saw blade head will be subjected to excessive force locally, causing the head to crack or the brazing layer to crack. In addition, frequent starting and stopping of the cutting equipment will cause the saw blade to be subjected to repeated impact loads, which will also shorten its service life. Operators need to master the correct cutting posture and force method, keep the cutting process stable, and avoid unnecessary impact and vibration. This is crucial to protecting the saw blade and extending its service life.
Cutting different types and states of glass will also have different effects on the saw blade. Glass of different hardness and thickness will wear the saw blade to different degrees when cutting. For example, when cutting tempered glass or ultra-clear glass with higher hardness, the wear rate of the saw blade will be significantly accelerated; when cutting thicker glass, the saw blade needs to withstand greater cutting force, which will also accelerate its loss. In addition, the flatness and cleanliness of the glass surface will also affect the use of the saw blade. If there are impurities, protrusions or unevenness on the glass surface, the saw blade will be unevenly stressed during the cutting process, increasing the wear of the saw blade. Therefore, choosing a suitable saw blade according to the specific situation of the glass and pre-treating the glass as necessary will help extend the life of the saw blade.
Maintenance after use is an important part of extending the service life of the brazed glass saw blade. After the cutting is completed, if the glass debris and cooling lubricant remaining on the surface of the saw blade are not cleaned in time, these residues will dry on the surface of the saw blade, which will affect the heat dissipation and lubrication effect of the saw blade during the next cutting, and may scratch the surface of the saw blade and destroy the integrity of the brazing layer. In addition, if the saw blade is not used for a long time and the storage environment is humid, it will cause the saw blade substrate to rust, which will affect the bonding strength between the brazing layer and the substrate. Therefore, the saw blade should be thoroughly cleaned and properly stored after each use. If necessary, a rust inhibitor can be applied to provide a good storage environment for the saw blade.
During the use of brazed glass saw blade, multiple operating factors such as equipment debugging, feed speed, cooling and lubrication, operating specifications, cutting objects, and maintenance will have a significant impact on its service life. Only by fully understanding and reasonably controlling these factors and standardizing the operating procedures can the performance of the saw blade be maximized, its service life be extended, the cost of use be reduced, and at the same time, the efficient and safe cutting work be ensured.
