Driven tool holders are also called "driven head", installed on the driven tool turret of the lathe center and can hold drill bits, milling cutters, and taps, which can rotate under the drive of the driven tool turret motor, drive the tool rotation, and can perform milling, drilling, and tapping processes on the workpiece after turning is completed.
With the increasingly complex processing of modern factory parts, the processing efficiency of precision grades has become a top priority for major factories. However, the lathe driven tool holders have the performance of multi-axis, high-speed, and high-efficiency. As long as it rotates along the bearing and transmission shaft, it can easily perform the processing of complex parts on the same machine, with high speed and accuracy. As an example, its maximum torque can reach 150Nm, and the maximum speed can reach 15,000r.p.m.. This reduces the time for the operator to change lathes.
In addition to processing, one of its major advantages is the use of an integral structure with good system rigidity. While performing processes such as lateral drilling, reaming, and thread processing, it can also obtain dimensional accuracy, shape accuracy, contour, and geometric element position accuracy of other items, so it can be described as being "rigid yet flexible". This avoids errors in inspections by operators. Due to the double guide rail design of the tool holder, it can maintain a relatively high level of accuracy and stability during operation.
The lathe driven tool holders can not only perform turning, drilling, and tapping, but also perform side, reverse, and contour cutting. It can even perform end cutting and maintain high speed. Moreover, one tool holder can complete all the processing steps of a workpiece, which conforms to the concept of one machine with multiple uses. Therefore, it has become an indispensable tool for any processing factory.
