**Title:** Super Hard! Process of Making Diamond Cutting Blades
**Location:** Diamond Tools Factory, Korea
**Product:** Diamond Cutting Blades
**Industry:** Manufacturing, Industrial Tools

#### **Manufacturing Process**

1. **Material Selection and Preparation:**
- **Diamond Selection:** High-quality industrial diamonds are carefully selected based on their size, shape, and toughness.
- **Metal Bond Composition:** The metal bond, which holds the diamonds in place, is formulated using a mix of metals such as cobalt, iron, nickel, and copper. The composition is tailored to the specific cutting requirements.

2. **Blade Design and Molding:**
- **Design Specifications:** The blade’s design, including its diameter, segment configuration, and diamond concentration, is determined by the intended application (e.g., cutting stone, concrete, or metal).
- **Segment Molding:** The diamonds and metal bond mixture are placed into molds to form segments. These segments are then pressed under high pressure to ensure uniform density and bonding.

3. **Sintering Process:**
- **High-Temperature Sintering:** The molded segments undergo a sintering process in a furnace, where they are heated to temperatures between 800-1000°C. This process bonds the diamonds with the metal matrix, enhancing the blade’s durability and cutting efficiency.

4. **Blade Core Preparation:**
- **Core Material:** The blade core, typically made from high-strength steel, is prepared and inspected for defects.
- **Segment Attachment:** The sintered diamond segments are precisely aligned and attached to the blade core through laser welding or high-frequency induction brazing. This ensures strong adhesion and alignment.

5. **Quality Control and Testing:**
- **Precision Testing:** Each blade undergoes rigorous testing for balance, straightness, and segment bonding strength.
- **Cutting Performance:** Sample blades are tested in real cutting conditions to evaluate their performance, including cutting speed, durability, and resistance to wear and tear.

6. **Finishing and Coating:**
- **Surface Treatment:** The blade surface is treated to prevent rust and corrosion. This may involve electroplating or applying a protective coating.
- **Final Inspection:** A final quality check ensures that the blade meets all specifications and performance standards before packaging and shipment.

#### **Factory Insights**
