Tungsten carbide round parts (hard alloy round parts) are one of our core competitive products. We select high-quality domestic and imported ultra-fine tungsten carbide substrates (such as Burgersen and Sandvik), and the cobalt content can be flexibly adjusted according to wear resistance or impact resistance requirements. Final processing is carried out through high-precision centerless grinding, CNC cylindrical grinding, and optical profile grinding, with diameter tolerance controlled at h5 level, roundness ≤0.001mm, and surface finish reaching mirror level. Tungsten carbide round parts, with their near-diamond hardness, excellent wear resistance, and good corrosion resistance, are widely used in precision stamping dies, drawing dies, powder metallurgy dies, precision measuring tools, and semiconductor packaging tools, significantly extending die life under harsh high-speed, high-load conditions.

Technology and Process
We specialize in customized tungsten carbide (cemented carbide) round rods, punches, drawing cores, tungsten carbide balls, and other precision round components. Using ultra-fine grain tungsten carbide materials, we achieve micron-level accuracy through multiple precision grinding processes under high hardness conditions. Diameter tolerance can reach h5 grade, roundness ≤0.001mm, while providing extended services including mirror polishing, PVD coating, and tungsten copper brazed components.
High Precision Centerless Grinding
Used for high-volume continuous machining of tungsten carbide round bar outer diameters. Through-through centerless grinding achieves ±0.002mm diameter tolerance. Combined with a coolant filtration system, it completely prevents grinding burns and ensures that the original hardness and microstructure of carbide materials remain unaffected.
CNC Cylindrical Grinding
Designed for step grinding and taper grinding of working sections such as tungsten carbide punches and core rods. Using diamond wheels with online dressing technology, we achieve step-to-step concentricity ≤0.002mm, cylindrical surface roughness Ra0.05 or below, with no spiral marks or vibration marks, meeting precision stamping requirements.
Optical Profile Grinding
Used for complex-profile tungsten carbide parts, such as cutting blades and fine blanking punches. Through optical projection magnification and precision alignment, ultra-fine profile machining is performed to achieve shape tolerance within ±0.002mm, while supporting extremely small R corners and sharp edge finishing structures.
