ABSTRACT:
Switching equipment for numerically controlled machine tools is provided with at least one controllable switch for initiating a measuring process and a switch control which closes the switch when a supply voltage appears on a connecting wire, for example on a power supply connecting wire of an electric pump for cooling water. Therefore it is possible to measure automatically without any additional program-steps of the central processing unit.
