Teknomotor QTC Electrospindles

Quick Tool Changers

In milling motors with a manual tool change system (MTC), the milling tool is placed directly in the ER collet in the spindle nose. This is an affordable solution and works well when the number of tool changes is limited. As the number of tool changes increases, an automatic tool changer (ATC) becomes interesting. An ATC is perfect for daily industrial use, but this system is also expensive. The price of the motor itself is not too bad, but many additional components are needed, such as pneumatics and a safety system, and the CNC control must also be programmed in such a way that the tool can be picked up and released in the correct position.

Together with Teknomotor, we have developed an intermediate solution that allows for quick tool changes, but does not have the complexity (and costs) of an automatic tool change system. With this so-called QTC system, entire tool holders can be changed quickly and manually. The spindle nose contains a mechanism that can accommodate an HSK tool holder. No air pressure is needed; only an Allen key is required for the change (we recommend using the supplied torque wrench).
