A carbide drill bit is a drill bit used for drilling hard materials (such as steel, iron, alloys, etc.). A carbide drill bit is a drill bit used for drilling hard materials. It is made of carbide material. Cemented carbide is an alloy material composed of metal carbides such as tungsten carbide, titanium carbide and cobalt. It has high hardness, high strength and high wear resistance, so it is widely used in the field of machining.
The manufacturing process of carbide drill bits usually includes the following steps:
- Material preparation: First, metal raw materials such as tungsten and titanium and carbide raw materials are mixed in a certain proportion, and then carbonized in a high-temperature furnace to prepare cemented carbide powder.
- Mold design: According to the drill bit specifications and drawing requirements, design the shape and size of the drill tip angle, chip flute, helix angle and other parts.
- Press molding: Pour the cemented carbide powder into the mold, and then press it under a certain pressure and temperature to obtain a cemented carbide blank.
- Sintering treatment: Put the cemented carbide blank into a sintering furnace for high-temperature sintering treatment to densify the cemented carbide material and improve its mechanical properties.
- Surface treatment: Finally, the sintered carbide drill bit is subjected to surface treatment, such as grinding, polishing, chrome plating, etc., to meet processing requirements and safe use.
Carbide drill bits are widely used in machining due to their high hardness, high strength and high wear resistance, long service life and low processing costs. At the same time, the carbide drill bit is also an efficient processing tool, which can achieve high-speed drilling and deep hole drilling, improving production efficiency. Carbide drill bit is an excellent tool for drilling hard materials. It has the characteristics of high hardness, high strength and high wear resistance, which can improve processing efficiency and reduce processing costs.
