About Tungsten carbide rod

Uses

  • Cemented carbide rods is with good wear resistance and bending strength. It can be used to manufacture tungsten carbide end mills, drill, reamers, taps, engraving bits, printed circuit boards special cutter, automobile special cutter, special cutter for engine, and watch processing. Ground tungsten carbide rod can also be made hard metal punches, dead centre, core rod, perforating tool, anti-vibration boring bar.

Process materials

  • Solid carbide rod is suitable for machining common steel, cast iron, carbon steel, alloy steel, stainless steel, nickel-based alloy, titanium alloy, heat-resistant alloy steel, hardened steel, glass fiber, plastic aluminum, hardened steel, composite wood, high hardness aluminum alloy, acrylic, PCB materials, etc.

Application industry

  • Tungsten carbide round bar is used in metalworking, woodworking, papermaking, packaging, printing, chemical, petroleum, metallurgy, electronics, and defense industries.

How to make ground tungsten carbide rod

Main process flow

powder milling → formula according to grade→ wet grinding → mixing → crushing → drying → sieving → adding forming agent → redrying → sieving to obtain a mixture → granulating →extrusion molding or mould pressing→ forming → low-pressure Sintering →blanks→inspect straightness, runout→ rough ground by centerless grinders → finish ground → measure the size →packing → storage
