⚡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 ↑

### 🏭 PRODUCTION PROCESS full process (clamp welding integrated production line)

1️ ** Tooth formation **

Youdaoplaceholder0 Precision forging +CNC machining → error ≤0.05mm!

▸ Surface treatment: Sandblasting for rust removal → as bright as mirror ✨

2️ Flux coating

Youdaoplaceholder0 Exclusive formula brazing agent → alloy welding strength ↑50%

(Close-up of flux application 🎯)

3️ Quenching process

🌡️ 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%!

### 💬 Real feedback from users

"After CHANGING THE picks of THIS HOUSE, drilling SPEED took OFF directly 🛫! The teeth that used to be replaced every two days can now be used every five days! -- Mr. Wang from Shanxi Coal Mine

The customized high-cobalt formula performs exceptionally well in the clay layer, so there's no need to worry about the knife sticking anymore!  "" -- Sichuan Tunnel Project Department

🔍 ** Did you know ** : The Angle of the alloy head of the picks affects drilling efficiency directly! Our home offers a full range of Angle customization from 15° to 45°
