Product Features
1. Utilizes low-pressure sintering technology for stable and reliable quality: the sintering pressure can reach 100 kgf, effectively eliminating internal porosity in the alloy and producing green compacts with excellent density, high hardness, and high strength. An advanced temperature-control system further minimizes variations in product quality.
2. Utilizing ultra-high-pressure automatic pressure-relief extrusion equipment, we can produce bars of various specifications. This fully automated extrusion line, imported from Germany, allows pressure to be adjusted according to different requirements, facilitating the production of bars in diverse models.
3. High-precision fine grinding of bar stock to achieve a mirror finish: A CNC grinding machine with higher polishing efficiency is used to rapidly remove the damage layer generated during the polishing process, thereby improving surface finish and attaining a mirror-like appearance. The dimensional tolerances for precision-ground bar stock are as follows: diameter tolerance D ≤ ±0.01 mm; length tolerance L ≤ ±0.5 mm.
4. Stable mechanical properties, easy weldability, high wear resistance, and high impact resistance.
Product Range
Zhuzhou Liling cemented carbide rods are primarily used for drill bits, milling cutters, reamers, and similar tools. They can also be employed in cutting, stamping, and measuring instruments.
They are used in the paper-making, packaging, printing, and non-ferrous metal processing industries. In addition,
They are widely used in the machining of high-speed steel cutting tools, carbide milling cutters, carbide tools, NAS tools, aerospace tools, carbide drill bits, solid carbide drills, high-speed steel, tapered milling cutters, metric milling cutters, micro-milling cutters, reamer guide sleeves, electronic tools, step drills, metal-cutting saws, double-protected drills, gun barrels, angle milling cutters, carbide rotary files, and carbide tools, among others.
Carbide rods are not only used in cutting and drilling tools—such as micrometer drills, twist drills, and vertical mining drill bits—but also as delivery needles, various wear-resistant roller components, and structural materials. In addition, they are extensively employed in numerous fields, including machinery, chemical engineering, petroleum, metallurgy, electronics, and national defense.
