Toolholder

A Mechanical Clamping Tool Holder / Mechanical Chuck, used on vertical machining centers and CNC lathes, is a tool-holding system designed to secure the cutting tool safely and rigidly by means of mechanical clamping force. In this type of holder, the clamping action is achieved through components such as a collet, nut, screw, clamping sleeve, or mechanical wedge mechanism. The applied mechanical force centers and locks the cutting tool shank inside the holder, allowing torque and cutting forces generated during machining to be transmitted reliably. On vertical machining centers, mechanical clamping holders are commonly used for holding end mills, drills, reamers, taps, and various rotary cutting tools. On CNC lathes and turn-mill machines, they are widely used especially in live tooling units and other cutting tool interfaces. The main advantages of mechanical clamping tool holders are high clamping force, rigid construction, wide application range, easy maintenance, and adaptability to different tool diameters. They provide a reliable and economical solution, particularly for applications requiring high torque and heavy-duty machining.
