Vacuum Brazing of Cemented Carbide Ultrasonic Cutting Tools (YG10) with Titanium Alloy

Vacuum brazing is a highly reliable joining process for manufacturing cemented carbide ultrasonic cutting tools made from YG10 grade bonded to titanium alloy holders. These tools are widely used in precision and ultrasonic machining applications, where high hardness, wear resistance, and vibration stability are essential.
The brazing process is carried out in a high-temperature vacuum brazing furnace, which provides an oxygen-free environment to prevent oxidation and ensure clean joint formation. A carefully selected brazing filler metal, commonly silver- or nickel-based, is placed between the YG10 cemented carbide cutting tip and the titanium alloy body. During heating, the filler metal melts and flows into the joint by capillary action, forming a strong and uniform metallurgical bond.
Vacuum brazing minimizes thermal stress and prevents cracking of the cemented carbide while maintaining its hardness and cutting performance. The titanium alloy holder provides lightweight strength and excellent vibration damping, which is critical for ultrasonic cutting operations. The finished tool exhibits high bonding strength, excellent wear resistance, and stable performance under high-frequency vibration.
Due to these advantages, vacuum brazed YG10 cemented carbide and titanium alloy ultrasonic cutting tools offer long service life, precise cutting accuracy, and reliable performance, making them ideal for advanced manufacturing and precision machining industries.
