Cemented carbide tipped

Carbide welding blades are the most common tool blades for metal cutting on cutting machines. They are generally used on turning tools and milling cutters.Nine points of use for cemented carbide welding inserts:1. The structure of the welded cutting tool should have sufficient rigidity. The rigidity is guaranteed by the maximum allowable dimensions and the use of higher strength steel and heat treatment.2, the cemented carbide blade should be fixed firmly. The cemented carbide welding blade should have sufficient fixedness. It is guaranteed by the sipe and welding quality. Therefore, the blade insert shape should be selected according to the blade shape and tool geometry.3. Carefully check the arbor. Before welding the blade to the arbor, it is necessary to check the blade and the shank. First, the blade bearing surface should be inspected without severe bending. The hard alloy welding surface must not have a serious carburizing layer. The dirt on the surface of the carbide insert and the groove in the shank should also be removed to ensure the welding is firm.4. Reasonable use of solder In order to ensure the welding strength, suitable solder should be selected. During the welding process, good wettability and fluidity should be ensured, and air bubbles should be eliminated, so that the welding and the alloy welding surface are in full and there is no shortage of welding.5, the correct choice of welding flux is recommended to use industrial borax, should be dehydrated in the drying furnace before use, and then crushed, screened to remove mechanical debris, to be used.6. When using mesh compensation gaskets to weld high-titanium low-cobalt fine-grain alloy and welding long and thin alloy inserts, in order to reduce the welding stress, it is recommended to use a sheet with a thickness of 0.2--0.5mm or a mesh aperture of 2--3mm. The mesh compensation pad is welded.7. Correctly adopting the sharpening method Because the carbide insert has high brittleness and strong sensitivity to crack formation, the cutter should avoid overheating or quenching during the sharpening process, and at the same time select the grinding wheel with proper grain size and reasonable grinding process. To avoid sharpening cracks and affect tool life.8. Correct installation of the tool When installing the tool, the length of the tool holder extending the tool holder should be as small as possible. Otherwise, it will easily cause the tool to vibrate and damage the alloy piece.9. Correct re-grinding and grinding tool When the tool is used to achieve normal blunt, it must be re-grinded. After re-grinding, the tool must be ground with the oil stone to sharpen the cutting edge and the tool tip. This will improve the service life of the tool. Safety and reliability.
