Carbide brazing inserts are commonly used metal cutting tool inserts on machine tools, and are generally used for turning tools and milling cutters. Tungsten carbide brazing inserts Nine points for the use of cemented carbide brazing inserts: 1. The structure of the brazing tool should have sufficient rigidity to ensure the maximum allowable boundary size, high-strength steel grade and heat treatment. 2. The carbide inserts should be fixed firmly. The cemented carbide brazing inserts should be firmly fixed, and its groove and brazing quality are guaranteed. Therefore, the groove shape of the inserts should be selected according to the shape of the inserts and the geometric parameters of the tool. 3. Please check the inserts carefully before brazing the inserts to the inserts. If necessary, check the inserts. First, check whether the supporting surface of the inserts is severely bent. There should be no serious carburized layer on the hard alloy brazing surface. At the same time, the dirt on the surface of the carbide inserts and the embedded groove of the inserts should be removed to ensure reliable brazing. 4. In order to ensure the brazing strength, suitable solder should be selected. During the brazing process, good wettability and fluidity should be ensured, air bubbles should be eliminated, and the brazing should be in full contact with the alloy brazing surface without lack of brazing. 5. It is recommended to use industrial borax to choose the correct brazing flux. Before use, it should be dehydrated in a drying oven, then crushed, and the mechanical debris is sieved out, ready for use. 6. When brazing high-titanium and low-cobalt fine-grain alloys and slender alloy insertss, in order to reduce brazing stress, it is recommended to use 0.2-0.5mm thick thin plates or 2-3mm mesh diameter patch gaskets for brazing. 7. Use the correct grinding method. The tool is brittle and has a strong sensitivity to the formation of cracks. The cutting machine should avoid overheating or quenching during the grinding process. At the same time, it is necessary to choose a suitable grinding wheel and a reasonable grinding process to avoid grinding cracks and affect the service life of the tool. 8. Install the tools correctly. When installing the tool, the length of the tool head extending from the tool holder should be as small as possible. Otherwise, it is easy to cause the tool to vibrate and damage the alloy sheet. 9. When the correct regrind and grinding tools are used to achieve normal dullness, regrind must be performed. The cutting edge and the rounded corners of the sharpening tool must be polished with oilstone to improve the service life, safety and reliability of the sharpening tool.
