In modern manufacturing, choosing the appropriate blade is crucial for improving processing efficiency and product quality. Below is a detailed analysis on how to choose the appropriate blade.
Firstly, starting from the information on the blade box, you may see a series of labels such as YBG205, M20-M40, WNMG060404-EM, etc. These markings are not only the model of the blade, but also have complex processing parameters behind them. Here we focus on introducing cutting parameters, including cutting speed (Vc), feed rate (fn), and cutting depth (ap). These three are known as the three elements of cutting and are key to ensuring smooth machining.
The cutting speed (Vc) is the surface speed at which the tool moves along the workpiece, usually provided by the blade manufacturer's data. This parameter directly affects the wear of the cutting tool and the surface quality of the workpiece. The cutting speed of workpieces with different diameters needs to be adjusted accordingly, and theoretically, the larger the diameter of the workpiece, the higher the cutting speed should also be. In addition, increasing the cutting speed appropriately usually improves production efficiency, but if it exceeds the tolerance range of the tool, it may lead to accelerated wear and even affect the surface quality of the workpiece. Therefore, understanding and selecting the appropriate cutting speed is crucial for improving machining efficiency.
Feed rate (fn) refers to the displacement of the tool relative to the rotating workpiece per revolution. This parameter not only affects the service life of the tool, but also affects the fracture state and shape of the chips. The ideal feed rate should ensure tool life while maximizing production efficiency. If the feed rate is too small, the tool life may be reduced, while if the feed rate is too large, it will increase the cutting temperature and accelerate tool wear. Therefore, choosing a feed rate that matches the characteristics of the tool is crucial.
Cutting depth (ap), also known as cutting depth, is the vertical distance between the unprocessed surface and the processed surface. A cutting depth that is too small can easily cause tool scratching and accelerate wear, especially when facing workpieces with hardened layers. The appropriate cutting depth should be chosen to prevent damage to the tool tip. Adjusting the cutting depth based on the power and actual working conditions of the machine tool can ensure that the tool performs cutting in the optimal state, thereby effectively improving the efficiency and lifespan of the tool.
Next, we will analyze the importance of blade models in detail. Different brands of cutting tools may be suitable for different materials and processing methods. Therefore, when selecting a blade, it is necessary to consult the technical information provided by the manufacturer to confirm the applicable scope and performance of the selected tool. This not only ensures the best match between the tool and the workpiece material, but also fully utilizes the performance of the tool during the machining process.
Overall, the selection of blades requires comprehensive consideration of multiple factors, including cutting parameters, tool materials, machining conditions, and workpiece characteristics. Reasonably utilize the information on the blade box, improve processing efficiency, reduce tool wear, and ultimately achieve high-quality product output.
