Подробное введение
What Are Precision-Engineered Cemented Carbide Brazed Tip Inserts?
Precision-engineered cemented carbide brazed tip inserts are cutting tools featuring a brazed carbide tip fixed onto a tool body. The carbide tip is composed of tungsten carbide particles bonded with a metallic binder, typically cobalt. This combination results in a material with exceptional hardness and wear resistance, ideal for cutting, milling, and drilling operations.
Working Principle
The working principle of cemented carbide brazed tip inserts hinges on the superior properties of tungsten carbide. In cutting operations, the carbide tip retains its sharpness and integrity even under high temperatures and pressures. The brazing process, which involves melting a filler metal to bond the carbide tip to the tool body, ensures a robust and durable connection capable of withstanding machining stresses.
How to Use
- Selecting the Right Insert: Choose the appropriate carbide brazed tip insert based on the material to be machined and the specific application.
- Установка: Mount the insert in the tool holder, ensuring it is aligned and secured.
- Adjusting Machining Parameters: Adjust cutting parameters such as speed, feed rate, and depth of cut according to the characteristics of the carbide brazed tip insert.
- Regular Maintenance: Regularly inspect and replace inserts to maintain cutting efficiency and prevent workpiece damage.
Производственный процесс
- Preparation: Clean and prepare carbide blanks to ensure a clean surface for coating adhesion.
- Coating Application: Apply the selected coating using Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD) processes.
- Контроль качества: Strictly test the coated inserts to ensure coating thickness, adhesion, and uniformity meet industry standards.
