Component Specifications

Definition
A tool shank is a critical mechanical component in bonding equipment that serves as the interface between the bonding tool (such as a welding electrode or ultrasonic horn) and the machine's spindle or actuator. It provides rigid mounting, accurate positioning, and efficient power transmission while maintaining thermal and mechanical stability during operation.
Working Principle
The tool shank operates by providing a standardized mechanical interface that ensures concentric alignment between the bonding tool and machine spindle. It transmits axial force, rotational torque (if applicable), and sometimes electrical current or ultrasonic vibrations from the machine to the working tool while maintaining precise dimensional stability under operational loads.
Materials
Typically manufactured from high-strength alloy steels (AISI 4140, 4340), tool steels (D2, H13), or stainless steels (17-4PH). Heat treatment to 45-55 HRC for wear resistance. Some applications use carbide-tipped or ceramic-coated variants for extreme conditions.
Technical Parameters
  • Shank Type HSK, BT, CAT, or custom
  • Taper Angle 7:24 or 1:10
  • Concentricity <0.005 mm TIR
  • Diameter Range 10-50 mm
  • Surface Finish Ra 0.4-0.8 μm
