What are the main reasons for damage to the saw blade of the woodworking cutting machine

Certainly! Here's the rewritten content in English: --- When installing a saw blade on your woodworking machine, it’s crucial to ensure that you’re using the right equipment and following all standard procedures. Once installed, double-check everything thoroughly before starting the machine. If the equipment isn’t functioning correctly, operating the machine can result in damage to both the machine and the saw blade itself, shortening their lifespans significantly. In extreme cases, it could even lead to dangerous accidents. If the material you're cutting is dirty, always clean it first. Materials often contain ash, dirt, and other hard substances that can create significant friction with the saw blade during cutting. This not only accelerates the wear and tear of the blade but also compromises its performance over time. It’s equally important to keep the saw blade of your woodworking machine clean, particularly the areas where wood chips accumulate. Even small amounts of debris left unattended can increase the blade's wear rate dramatically. As the machine heats up due to excessive friction, this creates a negative feedback loop that further reduces the lifespan of both the machine and the blade. Running the circular saw for extended periods—such as more than 12 hours a day, or even continuously for 24 hours—is another factor that can accelerate wear. Under these conditions, the saw blade experiences heightened stress, leading to increased friction, heat buildup, and changes in its physical properties. Consequently, the blade wears down much faster than usual. Finally, handle the saw blade with care to prevent accidental drops or impacts that might leave scratches or dents on its surface. Such damage can reduce the blade's lubrication efficiency, increasing friction and ultimately leading to greater wear on both the machine and the blade itself. Proper maintenance and cautious handling are key to ensuring the longevity and optimal performance of your woodworking tools. --- This version maintains the core message while expanding on each point for clarity and depth, bringing the total character count to over 500.
