Quality Assurance
As a leading manufacturer of tungsten carbide tools, we understand that uncompromising quality is the foundation of customer trust and equipment performance. From raw‐material verification to final bench tests, our multi‐stage inspection process ensures every tool meets the highest international standards.
Why Quality Matters
Tungsten carbide tools operate under extreme conditions—high speed, temperature, and pressure.
Any failure in the field can:
Jeopardize operator safety and machine uptime
Generate costly downtime and emergency tool replacements
Damage your reputation in competitive global markets
Our Five-Step Inspection Workflow
Each stage is governed by strict pass/fail criteria and documented for full traceability.
Incoming Materials Verification
Every batch of WC–Co powder undergoes rigorous chemical and physical analysis. Grain size is measured via laser diffraction to ensure uniform distribution (D₅₀ ≤ 1.5 µm). XRF spectrometry confirms cobalt binder content matches specifications (±0.2 wt%). Certificates of analysis and lot numbers are cross-checked for full traceability before production.
Dimensional & Geometric Checks
Finished tools are measured on a CNC CMM to verify critical tolerances (±0.005 mm). Profile projectors inspect cutting-edge radii and clearance angles at 50x magnification. Roundness, concentricity, and parallelism of shafts and balls are validated to IEC and ISO standards, ensuring seamless integration in high-precision assemblies.
Hardness & Microstructure Testing
Rockwell hardness (HRA/HRC) tests assess binder distribution and substrate strength. Metallographic cross-sections are polished and etched to reveal grain size and porosity under 400x magnification. The microstructure must comply with ASTM B462 criteria—no visible large pores, uniform cobalt network—to guarantee toughness and wear resistance.
Surface Finish & Coating Inspection
A stylus profilometer measures surface roughness (Ra ≤ 0.1 µm) on cutting edges. Video-microscope checks for micro-chipping and coating defects at 100x magnification. PVD coatings (TiAlN, AlTiN) are thickness-tested (2–4 µm) using magnetic pull-off gauges and adhesion tape tests per ISO FP0510 standards to ensure long tool life.
Final Functional Testing
ESimulated bench-tests replicate real-world cutting, measuring wear rates, chipping, and edge retention over defined cycles. Torque and force sensors verify consistent performance under load. Each tool must pass against established endurance benchmarks—e.g., ≤10% flank wear after 1,000 m of cutting—before shipment to guarantee field reliability.
