Successful series production hinges on the prevention of scrap or rework and the attainment of consistently good workmanship. The tool is a decisive factor here. Wear or tool breakage that go undetected for extended periods, especially during unattended operation, result in defective parts and unnecessarily increase costs. Therefore, exact measurement of tool dimensions as well as periodic control of wear are absolutely essential. For tool measurement on the machine, HEIDENHAIN offers the TT touch probe and the TL laser systems.

With the TT 140 triggering touch probe, the contact plate is deflected from its rest position, sending a trigger signal to the NC control, during probing of the stationary or rotating tool.

The TL laser systems operate without any contact. A laser beam probes the length, diameter or contour of the tool. Special measuring cycles in the NC control evaluate the information.
