I believe many friends who use angle grinders have heard this sentence. If the cutting blade of the angle grinder is installed backwards, it is particularly prone to dangerous situations such as exploding fragments. The reason for this view is mainly because the two sides of the cutting piece are different. One side is an ordinary unlabeled side; the other side is labeled, and there is a metal ring in the middle. Many people mistakenly think that the label side is facing outward. Let the outer pressure plate of the angle grinder hold it down, which is equivalent to holding down the entire cutting blade. So is this statement true? How to install the angle grinder cutting blade correctly?
How to install the angle grinder cutting disc correctly?
The main function of the metal ring of the angle grinder cutting disc is to use it for center positioning when making the cutting disc; the second function is to protect the rotating spindle of the angle grinder from wear; the third function is Avoid eccentricity of the cutting blade due to wear during long-term operation. Once the cutting blade is eccentric during high-speed rotation, it is particularly easy to explode. Therefore, the installation of the cutting blade requires concentricity, that is, the center point must be particularly positive. At the same time, as an important cutting and grinding tool, the angle grinder needs to replace the cutting blade regularly. The sharpness of the cutting blade directly affects the operating efficiency of the angle grinder.
Many people don’t know how to install the angle grinder cutting blade correctly, which not only affects efficiency, but also increases unsafe factors.
How to install the angle grinder cutting disc correctly? Correct installation steps
1. Prepare tools. The precise installation of the cutting blade requires the use of special tools, such as a cross-shaped screwdriver or wrench. The Vickers WU980 series brushless angle grinder is equipped with a special wrench, which is easy to use and greatly improves the installation efficiency of the cutting blade.
2. Install the cutting blade. First, install the flat side of the inner pressure plate into the spindle with the flat side facing inward, and rotate it until it is stuck; then put the label-free surface of the cutting piece and the convex side of the outer pressure plate with the convex side of the outer pressure plate facing outward, and install them into the spindle in sequence. Vickers cutting blades are made of abrasive material and resin, with higher durability and safety index.
3.Fix the outer pressure plate. After the cutting blade and outer pressure plate are installed, in order to ensure their stability, use the special wrench equipped with the Vickers
