These components are workholding devices, typically used in machining and other applications requiring precise and secure grip. One part serves as the clamping element, designed to constrict around a workpiece. The other part provides the structural support and mechanism for actuating the clamping force. An example involves securing a drill bit in a milling machine, ensuring accurate and stable operation.
Their significance lies in the ability to provide concentric clamping, which is essential for maintaining accuracy and minimizing runout. This leads to improved surface finish, extended tool life, and tighter tolerances in manufacturing processes. Historically, their development paralleled the advancement of precision machining, becoming indispensable tools in industries demanding high levels of accuracy and repeatability.
