Tungsten carbide saw blade tips for cutting

The cemented carbide welding tool is made of cemented carbide blades and ordinary structural steel knives by welding. It is made of dehydrated borax, copper, ferromanganese, glass powder and other solders. It is melted at high temperature to make alloy, high speed steel and cubic nitride. Boring, diamond, ceramic and other blades are bonded to the same type of shank to meet the requirements of machining operations. The most widely used welding blade is the cemented carbide welding blade. Because the hardness of the hard alloy is high, it can meet the requirements of most materials to be processed, and it is widely used compared with other materials.

Hard alloy welding inserts have high hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC); good thermal hardness (up to 900 ~ 1000 ° C, maintain 60HRC); good wear resistance. Carbide tools are 4 to 7 times faster than high-speed steel, and tool life is 5 to 80 times higher. The molds and gauges are manufactured. The life is 20 to 150 times higher than that of alloy tool steel. It can cut hard materials of about 50HRC, but hard. The alloy is brittle and cannot be cut. It is difficult to form a whole-tool with a complicated shape. Therefore, it is often made into blades of different shapes and is mounted on the body or the mold body by welding, bonding, mechanical clamping or the like.
