Increase of efficiency, reduction of cost and change to "lean production", however, optimizing quality at the same time.
So the today's requirements of the modern manufacturing. In order to carry for this development calculation, the positive taper lock was developed and tested in co-operation between the industry and the tool laboratory of the TH Aachen.

The positive taper lock connects the machine spindle as interface with the tool. The special requirements of a modern tool change system are:

• Particularly high changing accuracy and repeatability
• Safe transmission of high torques with a defined, radial location
• High static and dynamic flexural strength
• Particular suitability for high-speed operations in milling, drilling and turning machines
• Decrease of weight and building length opposite SK tools
• Simple handling
