Tool turret
The tool turret or turret head is a tool holder or holder for several tools when machining workpieces.

The “Multifix” system was a forerunner to the tool turret. The quick-change system made it possible to align turning tools for lathes exactly in a tool holder and then to connect the tool holder together with the tool holder to the tool slide in just two steps. This enabled the tools to be changed without losing any time. The system was invented in Switzerland in 1943 by JFMinder and JEWeigle.

When machining workpieces with machine tools , different tools are required for different work steps. So that the production process does not have to be interrupted after each step so that the tool can be changed, several tools are clamped in a rotatable tool holder. After each step, the tool turret is rotated into the working plane so that the right tool for the next step can be used. The tools are calibrated and clamped in the tool head in such a way that they are already correctly positioned in relation to the workpiece for the respective steps in series production.
Tool turrets are used in particular in automatic production with CNC machines for turning , milling and drilling . In complex production processes, the turrets are equipped with additional tools from a tool magazine using robots during the production process. Used or defective tools are also automatically recognized and replaced with new ones.
Systems
A distinction is made between linear, star, polygon, drum, crown and disc turrets.
