The following professional knowledge requires your patience to read.
Substrate feeding is the first and important step in the production of TCT saw blades. During this process, control the thickness, hardness, outer diameter size, and flatness of the substrate feed to ensure the effective continuation of the subsequent process.
The second step is the rough polishing process of the substrate, and the factory will use polishing equipment to polish and remove the oxide skin on the surface of the substrate. After polishing, the substrate surface should not have scratches or uneven surface irregularities, which not only improves the accuracy of the saw blade but also facilitates the subsequent process.
The third step is to expand the hole. The saw blade uses an automatic reamer to expand the center hole. This step requires ensuring that the concentricity and aperture size of the center hole are within the standard requirements, and the accuracy requirements are relatively high.
The fourth step is to use drilling equipment to perform drilling treatment on the parts that need to be welded to the cutting head. The surface at the opening position should be smooth and free of burrs. In this step, special attention should be paid to the opening angle and the wear of the opening grinding wheel. If the grinding wheel is severely worn, it is necessary to replace it with a new one in a timely manner to avoid negative impacts on the next welding process and the production of defective products.
That's right, the next step is welding. The factory will use automatic welding equipment to weld the cutting head onto each tooth of the saw blade substrate. For this process, during the quality inspection process, we will observe whether there are missing welds, defective welds, or weak welds in the welding cutting head area. Once these situations occur, we will consider it as a defective product.
The sixth step is to clean and dry the saw blade. After the above process, it is inevitable that some dust will adhere to the saw blade. Therefore, the main purpose of entering the cleaning process is to clean the oil and dust impurities on the surface of the saw blade. The purpose of drying the surface of the substrate is to ensure that the saw blade surface is free of impurities and water stains, in order to ensure the perfect progress of the next sandblasting process.
The next step is sandblasting, using sandblasting equipment to evenly sandblast the surface of the saw blade substrate. The most important step in this process is the uniformity of sandblasting to avoid unevenness or sand accumulation on the substrate surface.
The eighth step of this process is to use relevant equipment to grind the teeth of the blade on the saw blade substrate. This step requires ensuring that the blade is sharp and the surface of the blade is smooth without gaps.
After completing the grinding of the saw blade head, we will clean and dry the saw blade again. Clean the oil and dust impurities on the surface of the saw blade, and dry the water stains on the surface of the saw blade.
After completing the above steps, the TCT saw blade has roughly formed, and there are five more steps left. We will discuss and reveal them in the next product news.
