OEM Customized Tungsten Carbide Button Bits – High-Performance Cemented Alloy.

The detail information of product

. Definition & Issues (The "Why")

Cemented Tungsten Carbide buttons are the critical cutting teeth for rock drill bits, tunneling machines, and road headers. Buyers often encounter:

Thermal Shock & Impact Failure: Substandard powder metallurgy processes result in brittle buttons that fracture easily when encountering inconsistent rock hardness.
Rapid Profile Wear: Incorrect Cobalt (Co) content for specific formations leads to premature blunting, significantly slowing down the Rate of Penetration (ROP).
Shape Limitations: Special geological conditions require unique button profiles (Bullet, Ballistic, Spoon), but most factories only stock standard sizes.

Vina CNC eliminates these risks through our OEM Customization service, allowing clients to specify alloy grades and geometric shapes tailored to their specific equipment and terrain.

2. Technical Classification (The "How")

Alloy Grades: Premium WC-Co compositions with hardness ranging from 86 HRA to 92 HRA.
Tailored Geometric Shapes:
- Spherical/Ball Buttons: Maximum durability for extremely hard formations.
- Ballistic/Conical Buttons: Designed for fast penetration in soft to medium rock.
- Spoon/Parabolic Buttons: Optimized for high-productivity tunneling and coal mining.
HIP Sintering Technology: Utilizing Hot Isostatic Pressing (HIP) to remove internal porosity, increasing the alloy's density and transverse rupture strength.
Precision Grinding: High-accuracy finishing of the base diameter maintained at ±0.01mm for perfect interference-fit in drill bit bodies.

3. Technical Advantages (The "Proof")

Enhanced Performance: Extends drill bit service life by 20-40% using premium wear-resistant carbide grades.
Flexibility: Full capacity to manufacture based on custom 3D CAD drawings for DTH, Tricone, and Rotary bits.
Metrology: Rigorous microstructure analysis and hardness testing for every production lot.
