How are cemented carbides separated from the cutting tools?
Brazing heating to melt after the pain, you can take off!
Tools are usually brazed by high-frequency induction:The blade part on the induction coil, through high frequency alternating current induction electromagnetic field, the induced electromotive force generated in the workpiece surface coupling, forming eddy current on the metal surface by eddy current heat generated in the metal surface, the welding parts usually coated with solder powder, welding can be reached until the melting temperature of workpiece. Take off the blade, too.
The hard alloy cutter head and the tool body junction part are heated to 600~800 degrees, and the solder can be melted, and the cutter head and the cutter body of the carbide cutter can be separated.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.
