⚡The strongest rotary cutting teeth on the surface! Revealing the entire manufacturing process of "diamond drills" in mining engineering⚡

###💎 Core Materials: Hardcore CP combination

**Tooth body material**:

42CrMo/30CrMnTi alloy steel 💪  

Hardness range: HR48-52 (after quenching) | HRC43-47 (after tempering)

👉 The "skeletal system", equivalent to teeth, is the ultimate impact-resistant force!


**Alloy formula**:

🔹 Tungsten powder (W) → hardness bearing (hardness comparable to diamond!)


🔹 Cobalt (Co) → Toughness King (flexural strength increased by 30%+)


💡 The golden ratio is customizable! Different strata match different formulas:


- Soft rock strata → Cobalt content ↑


- Hard rock strata → Tungsten content ↑

🌡️ Cool to -196 ° C instantly!


➤ Hardness is directly maximized → Wear resistance is enhanced by 3 times!




4️ Tempering treatment

🔥 200-600 ° C precision control (different models may vary) :


| Temperature range | Characteristic variation |


|----------|----------|


| 200-300℃ | Maintain hardness + relieve stress |


| 400-600℃ | Toughness significantly improved |




5️ ** Ultimate polishing **


💎 Mirror finish → friction coefficient reduced by 15%!
