2、Performance Advantages of LBC12s Carbide Rods
Superior Wear Resistance
With a hardness of 91.5 HRA and ultrafine grains, LBC12s offers excellent wear resistance, reducing tool replacement frequency and lowering production costs.
High Strength and Toughness
The combination of 12% cobalt and a TRS of 4400 MPa makes LBC12s extremely strong. It withstands heavy cutting forces and impact loads, reducing tool breakage risks.
Thermal Stability
Carbide rods must endure high cutting temperatures. LBC12s retains hardness and edge stability under elevated temperatures, ensuring consistent performance in high-speed machining.
Dimensional Stability
The uniform microstructure guarantees minimal deformation, which is critical for producing precision cutting tools such as drills, reamers, and end mills.
Versatility
Its balanced properties make it suitable for multiple machining applications, from steel and stainless steel to cast iron and titanium alloys.
3、pplication Scenarios
The LBC12s tungsten carbide rod is widely used across industries due to its versatility and performance. Below are its primary application areas:
1. Cutting Tools Manufacturing
End Mills: For milling hardened steels, stainless steels, and non-ferrous metals.
Drills: For precision drilling with high feed rates and long tool life.

4、Features and Characteristics
Micro-Grain Technology: 0.6 μm ultrafine structure improves hardness without sacrificing toughness.
Uniformity in Quality: Controlled manufacturing process ensures consistent properties across batches.
High-Polish Capability: Smooth surface finish reduces friction and improves cutting efficiency.
Customization Available: Can be supplied as solid rods, coolant hole rods, or ground rods according to customer requirements.
5、Precautions and Best Practices
While LBC12s rods are robust, users should follow best practices to maximize tool life and ensure safety:
Proper Cutting Parameters: Avoid exceeding recommended cutting speeds and feed rates to prevent premature wear.
Coolant Usage: Use appropriate cutting fluids to control temperature and reduce thermal shock.
Grinding Considerations: Use diamond grinding wheels for re-sharpening to maintain edge precision.
Avoid Impact Loads: Even though the rods are tough, sudden impacts or incorrect tool clamping can cause breakage.
Storage and Handling: Store rods in a dry, clean environment to prevent corrosion of the cobalt binder.
6、Technological and Patent Innovations
