Use of cemented carbide tools

2019-05-10


  Structural parts: There are many products used for hard alloys as structural parts, such as rotary seal rings, compressor pistons, lathe chucks, grinding machine spindles, bearing journals, etc.

  Wear-resistant parts: wear-resistant parts made of hard alloys include nozzles, guide rails, plungers, balls, tire studs, snow shovels, and so on.

  Cutting tools: Carbide can be used as a variety of cutting tools. The amount of cemented carbide used in cutting tools in China accounts for about one-third of the total cemented carbide production, of which about 78% is used for welding tools and about 22% is used for indexable tools. The hard alloy for CNC tools only accounts for about 20% of the hard alloys for indexable tools. In addition, there are solid carbide drills, solid carbide small garden saw blades, and hard alloy micro drills.

  Mold: Carbide used as various types of molds accounts for 8% of total cemented carbide production. There are drawing die, cold die, cold extrusion die, hot extrusion die, hot forging die, forming die and drawing. Mandrel rods, such as long core rods, spherical core rods, floating core rods, etc., the use of various types of cemented carbide rolls for rolling wire has increased rapidly in the past decade, and cemented carbides for rolling mills in China have accounted for cemented carbide production. 3% of the total.

  Geological mining tools: Geological mining tools are also a major use of cemented carbide. China's geo-hard alloys account for about 25% of the total cemented carbide production, mainly used for impact rock drill bits, geological exploration drill bits, mining oilfield down-the-hole drills, roller cone drills and coal cutter picks. , building materials industry impact drills, etc.

  Cavity for high pressure and high temperature: The more common use is to produce top hammers and pressure cylinders for synthetic diamonds. Hard alloys for top hammers and cylinders account for 9% of the total cemented carbide production in China.

  Other uses: Carbide is used more and more widely. In recent years, it has been expanding in the civilian field, such as bracelets, case, zipper heads for high-end bags, and carbide labels.
