Followed the previous news, we continue to talk about the challenges we will face in making tungsten carbide textile slitter knives.
HUAXIN CEMENTED CARBIDE manufactures a wide variety of blades for use in the textile industry. Our Industrial blades are designed for precision cutting of textiles.
IV. Performance Matching and Failure Modes
1. Adaptability Challenges Due to Fiber Material Differences
| Fiber Type | Cutting Challenges | Tool Optimization Direction |
|---|---|---|
| Nylon | Melt adhesion | Hydrophobic coatings (e.g., fluorine-DLC) |
| Carbon fiber | Abrasive wear + fiber tearing | Ultra-fine WC grains (0.2 μm) + high Co (12–15%) |
| Aramid | Rapid edge blunting | Negative rake angle (-5° to -10°) + high-frequency hardened edge |
2. Typical Failure Analysis
Edge Chipping:
Caused by residual stress concentration → Apply cryogenic treatment (-196°C × 24h).
Excessive Wear:
Optimize Co content (6–10%) and WC grain size matching.
V. Industry-Leading Solutions for you
1.Additive Manufacturing (3D Printing) of Cemented Carbide Tools
Use binder jetting (BJT) to form internal cooling structures for thermal management.
2. Smart Monitoring and Life Prediction
Embed RFID sensors to monitor wear in real-time and enable replacement alerts.
III. Edge Processing and Coating Challenges
1. Ultra-Precision Edge Grinding Difficulties
Problem might be:
Achieving sharp edges (edge radius <5 μm) is hindered by high hardness (HRA ≥90), causing low grinding efficiency and rapid wheel wear.
Process Optimization:
Employ diamond wheels (grit size W10–W20) with electrolytic in-process dressing (ELID).
Adopt laser-assisted grinding (LAG) to reduce grinding force and improve surface roughness (Ra ≤0.1 μm).
