China Manufacturer CNC Cutting Machine Solid Carbide Cutting Tools Imperial Tungsten Carbide Rod

The production process of hard alloy rods mainly includes milling, formulation, wet grinding, mixing, crushing, drying, sieving, adding forming agents, re drying, sieving to obtain a mixture, granulation, pressing, forming, low-pressure sintering, external grinding and precision grinding (blank does not have this process), size inspection, packaging, warehousing and other steps. Among them, low-pressure sintering technology is one of the key technologies for producing high-quality hard alloy rods.

Hard alloy rods can maintain stable performance at high temperatures and have excellent corrosion resistance, making them suitable for long-term use in harsh environments. Hard alloy rods also have the characteristics of good red hardness, high elastic modulus, strong bending strength, and good chemical stability (acid, alkali, high temperature oxidation). Widely used in various cutting materials such as turning tools, milling cutters, planers, drills, boring cutters, etc., including cast iron, non-ferrous metals, plastics, synthetic fibers, graphite, glass, stone, and ordinary steel.
